Profile Section
200x75x2.5mm S355JR Uncoated Steel Z Profile
The 200x75x2.5mm steel Z profile is a cold roll-formed purlin section to EN 10162 with a 200 mm web, opposed 75 mm flanges with 25 mm edge lips and 2.5 mm sheet thickness, weighing a nominal 7.85 kg/m. Produced to order in uncoated S355JR 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 uncoated cold-rolled structural strip in grade S355JR (EN 10025), minimum yield about 355 MPa. Choose it when the same section has to carry more load than S235JR. The surface is bare — specify paint or hot-dip galvanizing in the quote for outdoor use.
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 200x75x2.5 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. S355JR is the higher-strength uncoated grade for load-bearing purlins, columns and frames where S235JR would need a heavier section. At a nominal 7.85 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, S355JR). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
