Profile Section
350x100x3.5mm DX51D+Z Galvanized Steel C Profile
The 350x100x3.5mm steel C profile is a cold roll-formed lipped channel to EN 10162 with a 350 mm web, 100 mm flanges, 30 mm stiffening edge lips and 3.5 mm sheet thickness, weighing a nominal 16.76 kg/m. Produced to order in galvanized DX51D+Z steel, it is the standard section for solar PV mounting structures, roof purlins and side rails, and light-gauge steel framing — supplied cut to your exact length with no waste on site. 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
C 350x100x3.5 is typically specified for solar PV piles, rails and bracing on fixed-tilt and tracker structures, roof purlins and wall side rails on industrial buildings, mezzanine joists, and light-gauge steel (LGS) wall and floor framing. Mounting holes and slots are punched in-line to your drawing, and the section pairs with standard smart-screw or bolted connections for fast assembly. 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 16.76 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.
