We maintain a continuous inventory of hi-tensile steel in three thicknesses (1/4", 5/16" and 3/8") and two grades (80 and 100 -- see below) to help you match factory strength and to achieve the RBM for your truck and its custom application.
Both grades are high strength, low alloy, automotive grade steels. They are produced for applications where high strength along with formability, weldability, toughness and fatigue resistance are required.
These steels are not heat treated -- they are produced to the desired tensile strength at the mill and are fully weldable and drillable. We are happy to provide a mill certification for any of the frames we fabricate for you.
