ST Fastening Systems manufactures steel-frame and post-frame fasteners for agricultural, industrial, commercial and residential metal roof and sidewall applications. Product strengths are drill point quality and corrosion resistance, as shown by the WOODBINDER MB drill point and ZXL zinc-aluminum alloy molded head. Both are enhanced by a powder coating paint system. Solid and vented closure strip systems, pipe flashings and other accessories round out the product line.
