• Rib-Bak® :: The heart of Nucor Steel Marion highway products.

• Made of tough new billet steel, with 25% greater tensile strength than competitor rail steel, RIB-BAK® is the strongest U-channel post available. The RIB-BAK® design withstands higher wind loads at crucial load bearing points thus supporting heavier signs per post. Contact points are flush surfaces, providing solid, more permanent sign attachment. Installation is typically completed with minimal time and conventional tools.

Multiple Sizes

Powder Coating at the Price of Paint . Only Nucor Steel Marion gives you the superior rust-resistant protection, durability and appearance of powder coating—at the price of paint. Called Powder-Shell™, it’s available for all sizes of RIB-BAK® in green, black, yellow, white, orange and brown (other colors by request). For the ultimate protection against the elements, RIB-BAK® posts are also available in hot-dipped galvanized (ASTM A-123). Crash Tested and Approved. RIB-BAK® U-channel signposts and breakaway systems are accepted by the FHWA (Federal Highway Administration) for small sign support applications, and also meet the NCHRP 350 criteria for occupant impact velocity. (NOTE: 3 lbs. /ft x 3 supports – and all 4 lbs./ft supports – must use breakaway hardware to comply with FHWA breakaway requirements.)
