Q235B equal angle steel hot-dip galvanized for structural framing, 架子, supports and outdoor installations.
Hot-dip galvanized angle steel is Q235B equal-leg angle immersed in a molten zinc bath. The zinc coating (typically 45–85 μm) protects the legs and inner corner from corrosion, making it the standard choice for outdoor structures, racking and transmission supports that demand long service life with minimal maintenance.
