Profile Section
240x85x3.5mm DX51D+Z Galvanized Steel U Profile
The 240x85x3.5mm steel U profile is a cold roll-formed plain channel to EN 10162 with a 240 mm web, 85 mm flanges and 3.5 mm sheet thickness, weighing a nominal 11.27 kg/m. Produced to order in galvanized DX51D+Z steel, the open unlipped face slides cleanly over panels and boards, making it the standard track, edge and closure channel in light steel framing and general fabrication — supplied cut to your exact length. This variant is pre-galvanized forming-grade strip DX51D+Z275 to EN 10346. It is specified for formability and a zinc coating, not for a stated structural yield — use S350GD+Z when the profile is load-bearing.
Made to Order — Roll Formed
This profile is roll-formed to order in your exact length (1–15 m; longer on project basis). Minimum production run is approx. 3000 kg per size and grade. Add your sizes to a quote request and our team confirms lead time and pricing within one business day.

Applications & Usage
U 240x85x3.5 serves as top and bottom tracks in light steel framing, edge and closure channels on sandwich panels and trapezoidal sheets, sliding-gate and door guides, machine guards, and cable or pipe routing in industrial fit-outs. Roll forming keeps the channel straight and uniform over the full length, so profiles arrive ready to fix. DX51D+Z275 suits non-structural tracks, edge channels, hat sections and light fabrication where the section must form easily and arrive already galvanized. At a nominal 11.27 kg/m and cut-to-length production from 1 to 15 m, material usage is optimized with no offcuts on site. Minimum production run is approximately 3000 kg per size and grade — add your sizes to a quote request and our team confirms exact tonnage, lead time and delivered pricing.

Indicative elastic section properties computed from the nominal centerline (thin-walled, corner radii ignored). For preliminary sizing only — not a substitute for a stamped structural calculation.
Load guidance is provided for structural grades (S235JR, S355JR, S350GD+Z). DX51D+Z275 is a forming grade with no defined structural yield.
