Profile Section
360x100x3.5mm S350GD+Z Galvanized Steel Z Profile
The 360x100x3.5mm steel Z profile is a cold roll-formed purlin section to EN 10162 with a 360 mm web, opposed 100 mm flanges with 30 mm edge lips and 3.5 mm sheet thickness, weighing a nominal 17.03 kg/m. Produced to order in galvanized S350GD+Z steel, the Z geometry nests and overlaps at supports, forming structurally continuous roof and wall purlin lines that carry more load with less steel. This variant is pre-galvanized structural strip S350GD+Z275 to EN 10346, minimum yield about 350 MPa. The zinc coating is already on the coil, which is why this is the standard grade for outdoor purlins and solar structures.
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
Z 360x100x3.5 carries roof and wall cladding on industrial halls, warehouses, agricultural buildings and solar carports; overlapped and bolted at supports it forms continuous multi-span purlin lines. Cleat and overlap holes are punched in-line to your purlin schedule, and anti-sag accessories are configured per project. S350GD+Z275 is the usual specification for solar mounting, roof and wall purlins, and any outdoor structure that needs a structural yield plus a zinc coating from the mill. At a nominal 17.03 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, S350GD+Z275). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
