Durable Seismic Q355 Steel Structure for Large Span Projects

Product introduction

A structural steel frame is a load bearing skeleton made of hot rolled columns, beams, and bracing members connected by welding or bolting. It supports floors, roofs, and exterior cladding while resisting wind, seismic, and gravity loads. Widely used in industrial buildings and high rises, it offers long spans and design flexibility.
