steel truss

Introduction to Steel Truss: Structural Backbone of Modern Construction

A steel truss is a prefabricated structural framework composed of steel members arranged in a triangular pattern. This geometric configuration allows the truss to efficiently distribute loads—such as weight, wind, and seismic forces—across its span, making it an essential component in roofs, bridges, towers, and industrial buildings. The inherent strength-to-weight ratio of steel, combined with the truss design, enables longer spans without intermediate supports, reducing material costs and construction time. Steel trusses are fabricated from hot-rolled sections, hollow structural sections (HSS), or tubular steel, and are typically connected via welding, bolting, or riveting. They are widely used in commercial, residential, and infrastructure projects due to their durability, fire resistance, and recyclability. The global steel truss market is driven by urbanization, infrastructure modernization, and the demand for sustainable building materials.
