PT 40 High Strength Fence Framework

Count on US Premier Tube Mills for high-strength steel tubing engineered to outperform Schedule 40 in strength and weight. PT 40 is the reliable choice for fence framework in commercial, industrial, and high-security applications. Built in the USA with advanced corrosion protection and 50,000 PSI steel, PT 40 is strong, efficient, and built to last.

Product Overview

PT 40 fence framework from US Premier Tube Mills is engineered for superior strength, durability, and corrosion resistance. Made in the USA using 50,000 PSI high-yield hot-rolled steel, PT 40 is 37% stronger and 21% lighter than Schedule 40 tubing, making it ideal for demanding fencing applications. Our advanced manufacturing process applies full interior zinc coating before forming, along with a triple-layer exterior system: steel-adhered zinc, a conversion coating, and a vacuum-sealed clear top coat for maximum corrosion protection.
