Z280×59×17×2 mm Steel Z Profile — S500
The 280x59x2mm steel Z profile is a cold roll-formed lipped purlin: 280 mm web, 59 mm flanges with 17 mm edge lips and 2 mm thickness, 6.52 kg/m. Roll-formed to order in S500 steel; Z purlins can be lapped at supports to form continuous roof and wall purlin lines. This page shows the size in black (uncoated) steel S500, minimum yield 500 MPa; other materials can be selected above.
Made to Order — Roll Formed
This profile is roll-formed to order in your length (1–25 m). The minimum order is 5000 kg per size and material. Add your sizes to a quote request and we confirm lead time and price.

Applications & Usage
Z 280x59x2 carries roof and wall cladding on industrial halls, warehouses and agricultural buildings; lapped and bolted at supports it forms continuous purlin lines. Holes can be punched to your purlin schedule. Black steel suits indoor structures and members that are painted or hot-dip galvanized after fabrication. Each size is roll-formed to order in lengths from 1 to 25 m. The minimum order is 5000 kg per size and material — add your sizes to a quote request and we confirm lead time and delivered price.

Weight and section properties are nominal values from the mill catalogue table. Values marked ≈ are calculated from the section centerline.
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, S500 (black steel)). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
| Span | Max UDL |
|---|---|
| 2 m | ≈ 41.99 kN/m |
| 3 m | ≈ 18.66 kN/m |
| 4 m | ≈ 10.50 kN/m |
| 5 m | ≈ 6.72 kN/m |
