C-Post and Square Post Comparison

C-Posts and square posts have a lot in common, but they also each have unique qualities that make them a great fit for certain types of applications. The good news is that a C-post and a square post with the same dimensions will fit the same applications. Above is a diagram illustrating the difference between the two and below, you'll find an explanation of each type of post and what types of applications they fit best.

C-Posts

 

The open channel of a C-Post allows air to circulate better, helping to avoid condensation buildup inside the post. They are also easier to drive than most square posts - without requiring the use of concrete - and also self-anchor better. This superior anchoring and holding power makes them a great fit for traffic applications and other applications with demanding conditions. When compared to standard square posts, C-posts have a shape that facilitates superior bending strength and flexibility.

 

Square Posts

 

Square posts are fully welded all the way around, meaning they offer greater strength and stability. Without the opening that a C-post has, they have a larger surface area for affixing fencing using screws or bolts. They work well with most residential and commercial fencing applications and are easy to install. A square post, when used with a post cap, can have a tight, sealed barrier to keep moisture and other elements out and protect the interior from rust and deterioration.
