Types of Lumber Uses for Wood Split Rail Fence

Farmers and ranches have been building wood split rail fence for decades. Their go to choice in lumber? Anything they could find. Whatever species of tree grew natively in the location they farmed was what they constructed the fence from.

However, today things are different. Because of how popular wood split rail fence has become, we now have many manufactures commercially manufacturing it. As a result, a trip to the local home center or lumber yard and you’ll be able to find it.

Today, commercially manufactured wood split rail fence come in three types of lumber. Western Red Cedar, Pressure Treated Yellow Pine and Black Locust Fence Posts with Hard Wood Rails. However, depending on region, one type of wood may be more readily available than others.

Black Locust Posts with Hardwood Rails

Black locust lumber is a very dense wood. As a result, making it very strong. Wood split rail posts made from black locust are stronger than any totter type of lumber. Therefore, an excellent choice for farm and ranch fence.

The extra strength of the locust fence posts is helpful when containing large farm animals like cattle and horses.

Locust posts last for decades without any maintenance or treatment. Not worrying about fence repairs is very appealing to farmers and ranchers.

The hardwood lumber used for rails comes from Poplar or Hemlock trees and taper down at the ends. Known as paddle ends. As a result, allowing them to overlap each other when inserted through the holes in the posts.

Large farm animals like to scratch themselves against fence posts. As a result, the posts shift or lean over time. Overlapping paddle ends prevent the rails from falling out if the posts should move.

With treated split rail fence, both the posts and rails are yellow pine. Chemicals pressurized into the lumber help fight against rot and decay. It is the only type of lumber that uses a chemical to fight the elements.

The post and rails are just like the locust posts and hardwood rails. However, not nearly as strong. Furthermore, the posts are more consistent when cut at the sawmill. Therefore, providing more of a uniform look that homeowners like.

For most residential and light farming purposes, treated wood split rail fence is more than strong enough. Because southern yellow pine grows so fast, it is readily available and more affordable than the other types of lumber. Life expectancy is between 15 – 20 years.

Cedar rails have different ends cut onto them from the other two types. Cedar rails have a tenon. The hole in a cedar post acts as the mortise. They fit together well when assembled. However, the tenon and mortise fit is not good for large farm animals that move posts around. The rails easily fall out as a result of them not overlapping.

Cedar trees are indigenous to the west coast. As a result, cedar fence sold in the eastern sates is often more expensive than the other two types of lumber. Furthermore, cedar does better in dryer climates.
