What is Aluminum Fence?
Aluminum fence is a type of ornamental fencing designed to mimic the classic look of wrought iron—without the heavy weight, rust, or maintenance. It’s a popular choice for both residential and commercial properties thanks to its durability, style, and versatility.
What Are the Main Parts of an Aluminum Fence?
An aluminum fence is made up of three main components:
• Pickets – These are the thin, vertical metal bars that make up the face of the fence.
• Rails – The long, horizontal pieces that run across the top, middle, and bottom. Most aluminum fence panels have three rails. Two-rail designs are common for pool fencing, while taller fences (6 feet and above) may have four rails for added stability.
• Posts – These are the larger vertical supports placed between each fence panel. They anchor the fence and provide the main structural support.
The pickets and rails form a panel or section, which is then attached to the posts to complete the fence line.
Why Does Aluminum Fence Look Like Wrought Iron?
Today, most fences that resemble traditional wrought iron are actually made from aluminum. That’s because aluminum offers the same classic appearance without the downsides of iron—such as rust, weight, and high maintenance.
So, why should you consider aluminum over other fencing materials?
Let’s explore some key reasons homeowners and businesses choose aluminum fencing.
Why Choose Aluminum Over Iron Fence?
Both aluminum and wrought iron fences are popular for their decorative and ornamental appeal. While iron is sturdier and preferred where maximum security is needed, aluminum offers several distinct advantages that make it the top choice for many homeowners and property managers.
Aluminum Fence Doesn’t Rust
One of the biggest benefits of aluminum fencing is its resistance to rust. Unlike steel or iron, aluminum doesn’t corrode, making it a truly low-maintenance solution. That alone makes it a top pick for homeowners who want to install a fence once and forget about it.
In coastal regions, salt spray is the leading cause of rust in metal fences. Most aluminum fence manufacturers combat this by applying durable powder-coated finishes, which are tested through salt spray tests measured in hours. These finishes ensure the fence can withstand even the harshest marine climates.
Northern climates pose a different challenge—road salt. During winter, salt is spread on roads, and passing vehicles throw that salt into the air, which eventually settles on nearby fences. Compounding the issue, small stones kicked up in the summer can chip paint or coating on steel fences. Once that coating is compromised, moisture and salt penetrate the metal, causing rust to form.
With aluminum, this isn’t an issue. Even if the surface coating gets damaged, the metal underneath doesn’t rust—making it a long-lasting solution in any climate.
Lifetime Warranty
Many aluminum fence manufacturers back their products with lifetime warranties. This provides extra peace of mind for homeowners.
Aluminum won’t rust, warp, twist, or rot like wood or iron. Its finish is baked on or powder coated to ensure long-term durability. There’s no need to paint, stain, or seal—ever.
That combination of low maintenance and a lifetime guarantee is hard to beat, which is why aluminum fences have become so widely used in residential and commercial settings alike.
Aluminum is Less Expensive Than Steel
Aluminum fencing is also more cost-effective than true wrought iron.
Wrought iron is still handcrafted by skilled fabricators who weld each piece together. The labor involved in creating those ornate designs is substantial—and so is the cost.
Aluminum fencing, on the other hand, is manufactured using hollow aluminum components and assembled using streamlined, automated processes. The result is high-quality fencing at a fraction of the price, without sacrificing style or strength.
Aluminum Fence is Rackable
Another advantage of aluminum is that it’s “rackable.” This means the panels can adjust to the slope of your yard without leaving unsightly gaps underneath.
Aluminum fence sections are held together with screws, allowing the pickets to pivot and follow changes in grade. Wrought iron panels are welded, so they must remain level between posts. That often creates stair-step gaps under the fence—bad for pets, kids, and pool safety compliance.
Rackable aluminum fences maintain a consistent look and function while preventing those triangular gaps. This makes them ideal for properties with uneven terrain or those requiring pool code compliance.
Common Uses for Aluminum Fence
Aluminum fence is a versatile solution used in both residential and commercial settings. Its most popular application is around swimming pools. It offers a secure barrier while maintaining clear visibility, helping keep children and pets safe.
Many aluminum fence styles meet BOCA pool codes. These codes regulate fence height, picket spacing, and the distance between horizontal rails to ensure safety.
Another common use is for containing dogs. Aluminum fencing keeps pets safe while allowing them to see beyond the yard—great for reducing anxiety and barking.
You’ll also find aluminum fences around parking lots, shopping malls, and gas stations. Businesses choose it for its balance of security and appearance.
Commercial and industrial properties benefit from taller aluminum fence styles. The narrow picket spacing and horizontal rail placement make them extremely difficult to climb.
Because aluminum fences are open in design, they don’t provide cover for intruders. This visibility acts as a deterrent, making it a smart choice for security-conscious property owners.

Aluminum Fence Styles
Aluminum fences typically come in two main styles: flat top and spear point. Both are popular, and the choice often depends on the location and purpose of the fence.
A major benefit for homeowners is that most manufacturers price all styles the same. This makes quoting easy and allows customers to choose their preferred design without extra cost.
Let’s take a closer look at each style.
Flat Top Aluminum Fence
he name suggests, flat top aluminum fences have a smooth, level upper rail. Most designs feature two or three horizontal rails, with slight variations among manufacturers.
Flat top fences are ideal for pools. The smooth top rail provides a convenient spot to hang towels or floaties. They’re also much safer than spear point designs, especially if someone tries to climb or jump over.
You’ll often see flat top aluminum fences around restaurant patios and outdoor dining areas. While the flat rails may invite sitting, they prevent injuries if someone stumbles or falls—especially where alcohol is served.
Daycares and playgrounds also benefit from flat top fences. They’re safer for children and reduce the risk of scrapes or pokes from exposed picket ends. When safety is a concern, flat top fences are a smart and stylish choice.
Spear Point Aluminum Fence
When people picture wrought iron fencing, they often imagine decorative spear points rising above the top rail. Aluminum fencing offers a similar look—without the rust or maintenance.
There are two main spear point styles: straight and staggered.
• Straight spear point fences have pickets cut to the same height for a clean, uniform appearance.
• Staggered spear point fences alternate high and low pickets for a more dramatic look.
Both options make fences harder to climb and are ideal for areas that need extra security.
For maximum protection, some designs feature outward-facing spear points, making it nearly impossible to scale the fence. This type of design is often used in commercial settings and cemeteries, where both security and appearance are important.
Spear point fences combine traditional style with strong deterrence—making them both elegant and effective.
Aluminum Fence Add-ons and Accessories
Once you’ve chosen your aluminum fence style—flat top or spear point—there are plenty of ways to personalize it with add-ons and accessories.
Manufacturers offer a wide range of options, including:
• Finials for decorative tops on pickets
• Rings between rails for a classic, ornamental look
• Ball caps for post tops
• Scrolls to add artistic flair
• Scalloped or arched sections for a curved profile
• Puppy panels (or doggy panels) for extra pickets at the bottom to keep small pets in
These accessories allow you to tailor the look of your fence to match your style and needs. Just keep in mind—add-ons can add up. While they enhance appearance, they also increase cost, so it’s smart to choose upgrades that align with your budget and priorities.
Puppy Picket or Panels
Most aluminum fences are designed to meet code, with picket spacing kept just under the 4-inch maximum—usually around 3-7/8”. That’s fine for most pets, but if you have a small dog or a young puppy, those gaps might still be too wide.
Puppy pickets, also known as puppy panels, are a popular solution. These sections feature closely spaced pickets—typically around 1-1/2” apart—across the bottom 18 inches of the fence. An extra horizontal rail is also added for support.
While puppy pickets do a great job of keeping small pets safe, there are a few tradeoffs:
• Cost: This upgrade significantly increases the price of each section.
• Practicality: Many homeowners skip this option, knowing puppies are rarely left outside unattended. By the time they are, most have grown large enough not to fit through standard spacing.
Still, if you’re especially cautious or have a very small breed, puppy pickets can provide added peace of mind.
Concave and Convex Fence Sections
Concave (scalloped) and convex (arched) sections add a visually striking curve to your aluminum fence. These sections change height across the span of the panel, giving a radius or arch-like appearance.
Typically, manufacturers offer a 6-inch height change across the section. For example, a 48” tall section with a concave curve will dip to around 42” at the center.
When considering concave or convex sections, be mindful of your fence layout. Most aluminum fence sections are 6 feet wide, but if your design requires cut sections, it can affect the look. A 2-foot cut section, for instance, might make the curve appear disproportionate to the rest of the fence.
To maintain a consistent, flowing look, it’s essential to plan carefully and ensure that sections with curves are placed where they can be fully appreciated.
Rings, Finials, and Scrolls
Rings
If you’re aiming for a more ornate and decorative look, adding rings, finials, or scrolls to your aluminum fence is a great way to enhance its visual appeal. Rings are typically mounted between the top two rails of a 3-rail fence section.
There are two methods for attaching rings to a fence section:
1. Post-installation attachment – Rings are added after the fence is installed, typically by screwing them onto the rails.
2. Manufactured-in rings – Some manufacturers offer rings that are integrated directly into the panel during the manufacturing process.
However, one important consideration when adding rings is that they limit the ability of the fence sections to “rack” (or follow the natural slope of the land). This means that sections with rings must be installed level, which can be an issue when dealing with uneven terrain.
Finials
Finials are decorative accent caps that sit atop the pickets of an aluminum fence. They add a touch of elegance and sophistication to the fence, and are available in several different styles. The three most common types of finials are the quad flare, triad, and fleur-de-lis.
• Quad Flare Finial: This finial has a distinctive four-sided arrowhead shape, topped with a small ball. It creates a sharp, bold look.
• Triad Finial: This finial features three pointed protrusions, one straight up with two curving outward on either side. It has a dynamic, angular design.
• Fleur-de-Lis Finial: This finial is similar to the triad but is much more ornate, with a graceful three-pointed shape. It evokes a classic, sophisticated aesthetic reminiscent of wrought iron designs.
While finials can certainly elevate the visual appeal of an aluminum fence, it’s important to note that they can significantly increase the cost of the fence. So, when considering finials, it’s essential to balance your desire for style with your budget.
Scrolls
Scrolls are ornamental additions to aluminum fences that add a touch of elegance and intricate detail. Often featuring floral or swirling designs, scrolls can be a beautiful way to enhance the visual appeal of your fence. They come in various shapes and sizes, providing a versatile way to customize the look of your fence.
Typically, scrolls are designed to fit over a single picket and extend to the left and right, filling the space between pickets. They can be easily attached after the fence is installed by screwing them onto the picket. Some homeowners opt to add a different color to the scrolls, allowing them to stand out even more, creating a striking contrast with the rest of the fence.
Unlike rings, which are often found on every picket, scrolls are usually added sparingly. A few scrolls per section or on a gate can create an attractive focal point without overwhelming the overall design. This subtle addition can elevate the aesthetic appeal of your aluminum fence while maintaining a balance of style and sophistication.
Aluminum Gates
Aluminum gates are highly versatile, coming in various sizes and configurations to meet your specific needs. They generally fall into two main categories: Single or Man Gates, and Double Gates.
Double Gates
Double gates are essentially two single gates combined to cover larger openings in the fence. These gates are perfect for situations where you need more space, such as crossing a driveway or when planning to access your backyard with larger vehicles. The placement and number of gates can be customized based on your needs, but you will need at least one gate for access to your fenced-in area.
Consider future projects when planning your gates. Do you anticipate needing to bring in larger machinery, like a bobcat or backhoe? Or perhaps a landscaper will be using commercial lawnmowers? In these cases, it’s advisable to plan for a larger gate to accommodate their equipment.
Man Gates or Walk Gates
Man gates, also called walk gates, consist of a single gate panel (known as a gate leaf) and are ideal for normal day-to-day foot traffic. They are typically 48 inches wide unless a specific need arises for a smaller or larger gate. In tight spaces, a 36-inch wide gate might be better, while a 60-inch wide gate can accommodate larger equipment, such as a riding lawnmower with a 42-inch cutting deck.
When in doubt, always opt for a larger gate. It provides flexibility and ensures you have enough room for future needs.
Double Gates for Larger Openings
Double gates are perfect for larger openings where access needs go beyond what a single man gate can provide. This could include crossing a driveway or periodically needing to drive a truck into your backyard. Double gates typically feature a drop rod, which keeps one leaf stationary while you use the other half as a standard man gate.
When more access is required, the drop rod can be lifted, allowing the second gate leaf to swing open freely for easy passage. This makes double gates an excellent solution for versatile access points.
Estate Gates
Estate gates are designed to handle larger openings and are constructed from heavier materials compared to standard gates. These gates are often used to create a grand entrance, particularly for driveways, and can be either single or double-leaf gates.
Estate gates are not only functional but also make a bold statement at the entrance of your property, adding curb appeal and enhancing security. Many estate gates are equipped with automated systems, allowing for remote opening and closing using electric gate operators.
These gates come in various styles and configurations, with some manufacturers offering customization to meet your specific needs. Estate gates are usually more ornate than standard gates, making them a focal point and a symbol of elegance for both residential and commercial properties.
Aluminum Cantilever Gates
Aluminum cantilever gates are a type of rolling gate that slides horizontally across an opening instead of swinging outward. They are an excellent solution when there is limited space for a swinging gate.
Cantilever gates roll parallel to the fence line, requiring minimal room to operate. This design allows them to cover larger spans compared to estate gates—some manufacturers can create cantilever gates with a single leaf that covers up to 34 feet in width.
These gates are particularly effective in areas with heavy snow accumulation, as they don’t require space to swing open. The design also makes them ideal for high-traffic areas, such as private parking lots or apartment complexes. Additionally, cantilever gates are easier to automate, making them a great choice for businesses and properties requiring frequent access.
Aluminum Gate Options
Aluminum gates offer a variety of customization options to suit both practical needs and aesthetic preferences. Just like aluminum fences, gates can be enhanced with arches or scallops, adding a decorative curve to the top of the gate. Rings and scrolls are also popular options for adding intricate detail and elegance.
For more personalized touches, estate gates often feature the homeowner’s initials or custom designs. Gate operator rails can be added for those who want to automate their gates, allowing for easy, remote-controlled access.
While gates without any additional features will match the style of your chosen aluminum fence, you have the option to make your gate stand out. Whether for increased curb appeal or a unique design, these customizable options allow you to tailor the gate to your exact preferences.
What Color Does Aluminum Fence Come In?
While wrought iron fences often bring black to mind, aluminum fences offer a variety of color options. Standard colors typically include Bronze, White, Grey, Beige, and Green. Much like fence style, color choices generally don’t impact the price, making it easy to customize your fence without worrying about extra costs.
Black remains the classic and most popular color for ornamental fences, but dark bronze is quickly becoming a close contender. With its more subtle contrast, dark bronze blends seamlessly into wooded areas or landscape beds, and it pairs well with the earth-tone colors commonly used in today’s housing designs. Additionally, some manufacturers offer matte and hammertone finishes for a unique look that suits various preferences.
Aluminum Fence Grades
Aluminum fence comes in three primary grades: Residential, Commercial, and Industrial. These grades cater to different needs based on strength, durability, and application. While each manufacturer may offer slight variations in specifications, here’s a general breakdown of the three main grades:
Residential Grade Aluminum Fence
Residential grade is the most common type, ideal for use in backyards, swimming pools, and to secure children and pets. It provides adequate strength for most residential applications and is the most popular choice for homeowners. This grade is available in the widest variety of colors and styles, making it a versatile and attractive option. Some homeowners associations require aluminum fences, making residential grade a popular choice.
Commercial Grade Aluminum Fence
ommercial grade aluminum fence is typically used by restaurants, bars, country clubs, and apartment complexes. It is also found around swimming pools in more upscale settings. The rails and pickets are generally larger and thicker than residential grade, which adds to the overall strength and durability. Commercial grade fences are ideal for applications that require a balance of security and aesthetic appeal.
Industrial Grade Aluminum Fence
ndustrial grade aluminum fence is the strongest and most durable of the three. It’s used in areas where security and strength are top priorities, such as large businesses, public pools, and amusement parks. Industrial grade fences are often taller (6 feet or more) but can also be found in lower heights, especially for hand railing applications. This grade makes a bold statement of security and toughness, making it perfect for high-traffic or high-risk areas.
Each grade is designed to suit specific needs, so choosing the right one depends on your security requirements and the intended use of the fence.
Aluminum Fence Posts
Just like the fence panels, the posts for aluminum fencing come in different sizes and grades to provide the necessary support and strength. The size of the posts varies based on the specific application and the type of fence you’re installing.
Post Sizes
Aluminum fence posts generally start at 2” square and can go up to 6” square for the heaviest gates. Larger posts provide better support, especially in areas that need to bear extra weight or withstand more stress.
Post Wall Thickness
The wall thickness of the posts plays a crucial role in the fence’s overall strength and stability. Thicker posts are generally more durable and can withstand more wear and tear, making them a better option for high-traffic areas or gates that will see more frequent use.
Gate Posts
Gate posts should always be the heaviest posts used in your installation. Gates receive the most abuse because they are frequently opened and closed, so having a sturdy gate post prevents issues like gates not swinging properly or failing to latch correctly.
For a long-lasting and trouble-free experience, it’s worth investing in heavier gate posts. For residential gates, we recommend 3” square posts or larger. This extra investment ensures that your gates will remain functional for years without the need for costly repairs or replacements.
Heights of Aluminum Fence
Aluminum fences come in a range of heights, allowing you to choose the one that best suits your needs and preferences. The available heights generally depend on the grade of aluminum, but here’s a general guide:
Common Heights
• 36” (3 feet)
• 42” (3.5 feet)
• 48” (4 feet) – This is the most popular height for residential installations.
• 54” (4.5 feet) – Often required for swimming pools to comply with safety codes.
• 60” (5 feet)
• 72” (6 feet)
• 84” (7 feet)
• 96” (8 feet) – Common for industrial and commercial applications where security is a concern.
Custom Heights
• Many manufacturers offer custom heights, but keep in mind that additional setup charges may apply.
Considerations for Height Selection
• Residential Fencing: A 4’ tall fence is the most common choice for residential properties.
• Swimming Pools: Depending on the local safety codes, a 54” height might be required to ensure the fence complies with pool safety regulations.
• Security or Pets: For industrial use or for keeping in pets, 6’ to 8’ tall fences are often recommended. Taller fences offer more security, but remember, aluminum fences are transparent, so they don’t provide privacy.
• Privacy: If privacy is your main concern, an aluminum fence might not be the best choice. For privacy, there are other materials available, such as vinyl fences, which offer solid panels for screening.
Choosing the right height depends on your specific needs and goals, whether it’s aesthetics, safety, or security.
Aluminum Fence Maintenance
One of the key advantages of aluminum fencing is its low maintenance nature, making it an ideal choice for homeowners and businesses alike. Here’s why:
Benefits of Low Maintenance
• No Rot or Warping: Unlike wood, aluminum will not rot, warp, or deteriorate over time. This ensures your fence maintains its strength and appearance for many years.
• No Rust: Aluminum is naturally resistant to rust and corrosion. Whether exposed to rain, snow, or humidity, it remains durable without the need for frequent repairs.
• Durable Finish: The finish on aluminum fences is designed to last. It won’t fade, chip, or peel like other materials, so you won’t need to worry about repainting or refinishing.
Simple Cleaning
• Aluminum fences require very little care. Occasional cleaning is usually all that’s needed, such as hosing off dirt, debris, or bird droppings. A gentle wash with soapy water and a soft cloth will keep your fence looking great.
No Painting or Staining
• Aluminum fences never need painting or staining, unlike wood fences, which require regular upkeep to preserve their look and protect them from the elements.
Long-Lasting Investment
• If you’re looking for a maintenance-free fence that offers a classy appearance and long-term durability, aluminum is a top choice. With proper installation, aluminum fences can last a lifetime, making them a valuable and reliable option.
In summary, an aluminum fence provides peace of mind with minimal upkeep, ensuring that your fence remains an attractive and functional feature for years to come.
Aluminum Fence Installation
Aluminum fence installation is relatively simple but requires precision to ensure proper alignment and secure attachment. The installation process can vary based on the method used to attach the fence sections to the posts. Here, we discuss two common installation methods: routed posts and posts with straps or brackets.
Routed Posts
The routed post method is the most common and provides a clean, secure way to install aluminum fence sections. In this method, the rails are inserted into pre-routed holes in the posts.
How It Works:
1. Set the First Post: Begin by digging the first hole, setting the post, and securing it with concrete.
2. Insert Rails into the Routed Holes: After the first post is set, the rails are inserted into the routed holes of the post.
3. Align and Secure Sections: Use the sections as guides for spacing and alignment. Once the rails are in place, they are secured with self-tapping screws.
4. Continue the Process: Dig the next hole at the end of the section, set the post, and repeat the process for each section.
Advantages:
• The routed post method provides a strong, secure connection between the posts and rails.
• Once installed correctly, the sections cannot be easily removed, ensuring the fence remains sturdy.
• This is generally the easiest method for installing aluminum fence, especially for DIYers.
Considerations:
• You must build the fence as you go, which means you can’t set the posts first and insert the rails later.
• It requires careful measurement and alignment to ensure that the sections fit securely into the posts.
Posts Straps or Brackets
How It Works:
1. Set the Posts First: Begin by setting all the posts first. Ensure they are spaced correctly, as the distance between posts must match the length of the fence sections. If the spacing is too small, you’ll need to trim the sections; if too large, the sections won’t fit.
2. Attach Sections with Straps or Brackets: Once the posts are set, you attach the fence sections using straps or brackets. This allows you to adjust the height of the sections before securing them permanently.
3. Secure with Finial Set Screws: After the sections are attached and adjusted, secure them with finial set screws or fasteners.
Advantages:
• Flexibility: You can adjust the height of the fence sections before they are permanently secured, which is helpful if you need to make slight adjustments.
• Easy to Remove Sections: If you need to access the fenced area in the future and don’t have a gate large enough, sections can be easily removed.
Considerations:
• Requires precise measurements between posts to ensure the sections fit correctly.
• You need to plan carefully to avoid issues with spacing and adjustments.
Conclusion
Aluminum fencing is one of the most popular choices today, adding an elegant and timeless touch to your yard. Its low-maintenance nature ensures it will remain beautiful for years, while its subtle design is considerate of neighbors and highly favored by HOAs.
If privacy isn’t a concern, aluminum is the perfect option—offering long-lasting durability and serving as a valuable selling point if you ever decide to sell your home. With a wide range of colors, styles, and height options, aluminum fences can be customized to meet your needs.
Now that you’ve explored this guide, you’re equipped with the knowledge to make an informed decision when purchasing an aluminum fence. Enjoy the benefits of your new fence!
