Product Overview

W-Beam is an American wide-flange, hot-rolled structural steel section designed for main load-bearing and supporting systems. It is manufactured according to ASTM A6/A6M-22, ASTM A992-22, ISO 657-2017, EN 10034-2019 and GB/T 11263-2017, making it suitable for North-American standard projects as well as cross-regional engineering procurement.

The product covers a comprehensive W-Series range from W4×13 to W44×335, including commonly specified sections such as W6×15, W8×24, W10×30, W12×50, W14×53, W16×67, W18×71, W21×55, W24×84, W27×94, W30×124 and W36×150. Material options include A992, A36, A572 Gr.50/Gr.60 and A588, with Q235B, Q355B, S235JR and S355JR also available for specified projects.

Standard delivery lengths are 6 m and 12 m, while customized lengths from 3 m to 18 m and cut-to-length processing are supported. Surface options include hot-rolled black finish, shot blasting, pickling, anti-corrosive coating, hot-dip galvanizing and fire-retardant coating. Fabrication services include end beveling, drilling, cutting, welding and component assembly according to customer drawings.

W-Beams are mainly used in North-American-style buildings, bridges, industrial facilities, new-energy projects and port engineering. Typical applications include building columns and roof girders, bridge girders and cross beams, factory frames, crane beams, equipment bases, photovoltaic support frames, wind-turbine base structures, power-station structures and port equipment racks.
