Wide Flange (WF)

Structural H-section beams for columns, girders, and heavy frames.

Wide Flange (WF) is the H-shaped structural profile at the backbone of modern construction — used for columns, girders, multi-storey frames, bridges, warehouses, and wide-span canopies. Its excellent strength-to-weight ratio makes structures more efficient and faster to erect than conventional concrete.

We stock WF 100 through WF 900 in standard 12 m lengths, SNI / JIS G3101 SS400 grade, sourced from Garuda Yamato Steel and Krakatau Steel, complete with mill certificates. Non-stock sizes are available on an indent basis.
