MiTek Posi-Strut Metal Webs: Precision and Performance
MiTek Posi-Strut Metal Webs are innovative V-shaped steel components designed to enhance the strength and versatility of parallel chord timber trusses. Used primarily in Posi-Joists and Posi-Rafters for floor and roof applications, these metal webs combine the lightness of timber with the durability of galvanized steel.
Their open-web design facilitates easy installation of utilities, making them ideal for residential, commercial, and industrial construction projects requiring long spans and efficient service integration.
History
Introduced by MiTek in the 1970s, Posi-Strut Metal Webs revolutionized timber truss systems by addressing the limitations of solid timber joists. The design, featuring V-shaped metal webs with integrated connector plates, was developed to provide greater span capabilities and simplify utility installation. Over the years, MiTek has refined the Posi-Strut system with advanced manufacturing techniques and engineering software, ensuring compliance with standards like NCC Australia, NZBC New Zealand, and British/European fire codes. Today, Posi-Struts are a trusted solution globally, manufactured by licensed fabricators using MiTek’s cutting-edge design tools.
