Yes, European IPN (tapered-flange I-beams) replace GB I-beams, with design adjustments for flange geometry:
IPN 200 (EN) vs. GB I20b: IPN 200 (depth 200 mm, flange width 100 mm, web thickness 6.5 mm, weight 31.9 kg/m) vs. GB I20b (depth 200 mm, flange width 102 mm, web thickness 9 mm, weight 31.07 kg/m). IPN's tapered flange enhances load distribution, suitable for heavy loads.
Substitution Steps: Adjust bracket design to fit tapered flanges (slotted holes for bolt alignment) and recalculate load capacity using IPN's section modulus (IPN 200: 237 cm³ vs. GB I20b: 250 cm³). Welding uses the same parameters, so no process changes are needed.
IPN beams are ideal for GB substitutions where enhanced load distribution is critical.
