Product Overview

Angle Steel is a hot-rolled L-shaped structural steel product available in both equal angle steel and unequal angle steel configurations. It is designed for structural connections, supporting brackets, bracing members and reinforcement components across construction, municipal engineering, industrial facilities and new-energy projects.

The product range covers comprehensive dimensions for international project procurement. Equal angle steel is available from 20×20 mm to 250×250 mm, with thicknesses from 3 mm to 20 mm, while unequal angle steel covers mainstream sizes from 32×20 mm to 200×125 mm, with thicknesses from 3 mm to 16 mm. Non-standard thicknesses and extra-thick equal angles can be customized.

Material options include Q235B, Q355B, Q345B and Q420 for Chinese-standard projects; A36, A572 Gr.50 and A588 for American-standard projects; S235JR, S275JR and S355JR for European projects; and SS400 and SM490B for Japanese-standard orders. Standard lengths are 6 m, 9 m and 12 m, with customized lengths from 3 m to 18 m, as well as cut-to-length and segment cutting services.

Surface and fabrication options include hot-rolled black finish, shot blasting, pickling, anti-corrosive coating, hot-dip galvanizing, electro-galvanizing and fire-retardant coating. Cutting, drilling, punching, chamfering, welding, assembly and special bending can be performed according to customer drawings.
