Steel beams from Guangdong Junyou Steel Structure Co., Ltd are critical load-bearing components, engineered in I, H, and C profiles to support vertical/horizontal forces in construction. Manufactured from Q235 to Q690 steel, they offer tensile strengths 375-700MPa, enabling spans up to 15m in residential buildings and 30m in industrial facilities. Key variants: - I-beams: Lightweight, used in floors/roofs (100-600mm height). - H-beams: Heavy-duty, for columns/bridges (flange widths 100-600mm). - C-beams: Versatile, for purlins/racking (80-300mm depth). Fabrication includes hot rolling (standard sizes) or welding (custom lengths up to 12m). Surface treatments—zinc plating or powder coating—resist corrosion, crucial for humid/coastal projects. These beams integrate via bolted connections (for easy disassembly) or welding (for rigidity). In seismic zones, they’re paired with bracing to absorb lateral forces. Compliant with GB/T 11263 and ASTM A992, they’re trusted in projects from warehouses to high-rises, delivering strength with material efficiency.
