Rib-Bak U-Channel signposts are the heart of Nucor Steel Marion’s highway products. Made of tough new billet steel, it is the strongest U-channel post available, especially in the crucial load-bearing points. Its patented ribbed-back design withstands higher wind loads and saves money by supporting a lot more sign per post. Its contact points are flush surfaces, providing a solid, more permanent sign attachment.
