NPI Beams (IPN)
NPI (IPN) profiles are classic European I beams with 14% tapered flanges. Their narrower, thicker flanges make them the choice for machinery building, crane rails, track applications and traditional structural details. We supply from stock per DIN 1025-1 dimensions and EN 10024 tolerances.
