Structural Steel
Built-Up Welded H-Sections
Welded from plate to the depth and thickness your design needs.

Welded H and I sections, tapered members and plate girders made from plate where rolled sections are too small, too heavy or unavailable.
Rolled sections come in fixed sizes; built-up sections are made to measure. By welding flanges and webs from plate we can match each member to its forces – deeper for long spans, thicker for heavy loads, tapered where the moment changes – and save steel compared with the nearest rolled size.
Our automatic submerged-arc welding lines produce sections up to about 2 m deep with full traceability of plate and weld records, ready to be cut, drilled and painted with the rest of your frame.
