Unequal Angle Carbon Steel — Factory Direct Supplier | Huaxia-Steel
Huaxia-Steel supplies unequal angle carbon steel for structural frames, towers, brackets, shelving and machinery supports. Unequal leg angles provide asymmetric support where one leg must carry more load than the other, making them ideal for cantilevers, lintels, connection plates and reinforced frames.

Product Overview
Unequal angle steel has two legs of different widths joined at 90 degrees. Standard sizes range from small 25 × 16 mm sections up to large 200 × 125 mm sections, with thicknesses from 3 mm to 20 mm. We can cut lengths to 6 m, 9 m or 12 m, and provide holes, notches or welded connection plates on request.
