Our angle steel undergoes rigorous quality control throughout production. Premium raw materials pass preliminary inspection before being heated to 1200–1300°C and hot rolled into equal and unequal L-shaped profiles.
Following controlled cooling and straightening processes, angles are cut into standard lengths of 6m, 9m or 12m. Surfaces are cleaned and can be coated for anti-corrosion protection.
Every production batch is fully tested covering chemical composition, mechanical properties and dimensional tolerance to satisfy corresponding industry standards. Reliable strapping or palletized packaging is adopted to guarantee safe shipment across international destinations.
High-quality hot rolled steel angle bars are widely used across construction, industrial, and fabrication projects due to their excellent weldability, formability, and cost-effectiveness.
