Welded H Beam GL1-1: H1000×250×10×14, Q355B, 778 kg

Welded H beams (built-up H sections) are custom-fabricated from steel plates, used where standard hot-rolled sections are too small or where non-standard depth/width is needed. Below is member GL1-1 from an actual fabrication drawing.​

Section Composition

The beam is built from three main plates:

Part	Spec	Length	Qty	Weight
Web plate	PL10×985 (t×h)	5,446 mm	1	325.0 kg
Top flange	PL14×250 (t×w)	5,349 mm	1	147.0 kg
Bottom flange	PL14×250 (t×w)	5,461 mm	1	150.0 kg
Total section	H1013×250×10×14	—	—	622 kg

Plus stiffeners, end plates and connection plates bring unit weight to 778 kg.

Stiffener Details

Transverse stiffeners are welded to the web to prevent buckling under shear:

· L-15 (PL8×120): 2 pcs, end stiffeners

· L-26 (PL10×167): 4 pcs, intermediate stiffeners

· L-40 (PL10×150): 6 pcs, shear stiffeners

· LP-16 (PL8×150): 6 pcs, web stiffeners

Stiffener spacing matches load diagram — denser near supports where shear is highest.​

Why Welded H Beam

1. Custom size — depth from 300 mm to 3,000 mm, any width; no mill size limitation

2. Higher load capacity — 1000 mm deep beam carries long-span loads that standard HN500 cannot

3. Q355B material — higher yield strength than Q235, lighter weight for same load

4. Efficient fabrication — web + two flanges, automated submerged-arc welding

5. Built-in stiffeners — tailored to shear and moment diagram, no over-design

Typical Applications

1. Long-span warehouse & factory — 1000 mm deep beams span 12–18 m without intermediate columns

2. Building transfer truss / transfer beam — welded H beams carry column loads in high-rise transfer floors

3. Platform & equipment support — custom depth fits heavy machinery, tanks and conveyor platforms

4. Bridge girder (small span) — welded plate girders for pedestrian bridges and small vehicle bridges

5. Stadium & auditorium roof — long, deep beams support cantilevered roof structures​

Fabrication Notes

· Web-flange weld: full penetration submerged arc weld, UT tested per GB 50205

· All plates cut by CNC flame or plasma, then drilled for bolted connections

· Surface blast cleaned to Sa2.5, painted per project specification
