RIB-BAK U-Channel Sign Posts
The Nucor RIB-BAK is the strongest U-channel post available. New US billet steel has 25% more yield strength (80 – 100 KSI) than the rail steel used by competitors. Nucor posts are crash worthy to NCHRP 350 criteria. This RIB-BAK post withstands higher wind loads at crucial load bearing points, thus supporting heavier signs per post. Note the green posts are powder coated not painted, giving them higher chip resistance and a longer life. The U-Channel design provides a flush contact points for solid sign attachment

"The direct-bury Rib-Bak U-Channel post offers a strong, cost-effective solution to your sign support requirements. It is also the foundation of all breakaway systems.
The Rib-Bak is the strongest U-Channel available on the market today. It is produced from new-billet steel with a minimum tensile strength of 80,000 psi, and a minimum yield strength of 100,000 psi. New-billet steel is produced from 100% recycled scrap steel. Other u-channel is produced from re-rolled railroad rails with only 60,000 psi minimum tensile and 80,000 psi minimum yield. The Rib-Bak U-Channel offers 25% greater strength and wind load capacity, while its higher carbon content gives you the breakaway characteristics you need."
