European HEB (European Wide Flange, Medium) H-beams are nearly identical dimensionally to China's GB HW (Wide Flange) H-beams, making them direct substitutes for heavy-load applications. Key dimensional comparisons for common sizes include:
HEB 200 vs. HW 200x200: Both have a depth of 200 mm, flange width of 200 mm, web thickness of 8 mm, and flange thickness of 12.5 mm (HEB 200) vs. 12 mm (HW 200x200)-a 0.5 mm difference well within EN/GB tolerances (±0.8 mm for flange thickness). The weight per meter is nearly identical: 56.7 kg/m (HEB 200) vs. 56.7 kg/m (HW 200x200).
HEB 300 vs. HW 300x300: Depth 300 mm, flange width 300 mm, web thickness 10.5 mm, flange thickness 16 mm (HEB 300) vs. 15.5 mm (HW 300x300). Weight per meter: 94.5 kg/m (HEB 300) vs. 94.0 kg/m (HW 300x300)-a negligible 0.5 kg/m difference.
HEB 400 vs. HW 400x400: Depth 400 mm, flange width 400 mm, web thickness 13 mm, flange thickness 21 mm (HEB 400) vs. 20.5 mm (HW 400x400). Weight per meter: 142 kg/m (HEB 400) vs. 141 kg/m (HW 400x400).
EN 10210-1 and GB/T 11263 share identical dimensional tolerances for critical parameters (depth, flange width, web thickness), ensuring HEB and HW beams fit the same brackets, bolts, and structural connections. This dimensional harmony eliminates the need for design modifications when substituting HEB for HW.
