NPU Channels (UPN / U Sections)
NPU (UPN) profiles are classic European channels with tapered inner flange faces. They serve as chassis, frames, stair stringers, connections and stiffeners across steel construction — and back-to-back as columns and beams. We deliver from stock per DIN 1026-1 dimensions and EN 10279 tolerances.
