UAP channels with parallel flanges (NF A 45-255)

Standard: NF A 45-255 (dimensions) · EN 10279 (tolerances)

UAP is the French series of parallel-flange channels, still rolled by a few European mills alongside the UPN and UPE. Parallel flanges make bolted connections simpler, because no tapered washers are needed.

Notes

Section properties are calculated for the nominal dimensions. Mass is for a density of 7.85 kg/dm³.
UAP sizes are less widely stocked than UPN and UPE; check availability before specifying them.
