Profile Section
160x70x3mm S235JR Uncoated Steel C Profile
The 160x70x3mm steel C profile is a cold roll-formed lipped channel to EN 10162 with a 160 mm web, 70 mm flanges, 25 mm stiffening edge lips and 3 mm sheet thickness, weighing a nominal 8.24 kg/m. Produced to order in uncoated S235JR 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 uncoated cold-rolled structural strip in grade S235JR (EN 10025), minimum yield about 235 MPa. The surface is bare — specify shop painting or hot-dip galvanizing in the quote when the profile will be used outdoors.
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 160x70x3 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. S235JR is the general structural grade for indoor frames, painted purlins, and profiles that will be hot-dip galvanized after roll forming. At a nominal 8.24 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.
Indicative load span (single span, simply supported)
Allowable uniformly-distributed load (kN/m) limited by elastic bending about the strong axis (γ = 1.5 on yield, S235JR). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
