C-Posts Comparison Picture

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 concrete use- and also better self-anchor.

This superior anchoring and holding power make them a great fit for traffic applications and other applications with demanding conditions. Compared to standard square posts, C-posts have a shape that facilitates superior bending strength and flexibility.

Square Posts Comparison Picture

Square posts are fully welded all the way around, offering greater strength and stability. Without a C-post opening, 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. When used with a post cap, a square post can have a tight, sealed barrier to keep moisture and other elements out and protect the interior from rust and deterioration.
