Z360×60×18×2 mm Steel Z Profile — S420GD+Z275
The 360x60x2mm steel Z profile is a cold roll-formed lipped purlin: 360 mm web, 60 mm flanges with 18 mm edge lips and 2 mm thickness, 7.84 kg/m. Roll-formed to order in galvanized S420GD+Z275 steel; Z purlins can be lapped at supports to form continuous roof and wall purlin lines. This page shows the size in pre-galvanized strip S420GD+Z275: Z275 zinc coating (275 g/m² in total on both sides), minimum yield 420 MPa.

Applications & Usage
Z 360x60x2 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. Pre-galvanized strip is the usual choice for outdoor purlins, rails and solar mounting structures. 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, S420GD+Z275). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
| Span | Max UDL |
|---|---|
| 2 m | ≈ 51.70 kN/m |
| 3 m | ≈ 22.98 kN/m |
| 4 m | ≈ 12.92 kN/m |
| 5 m | ≈ 8.27 kN/m |
| 6 m | ≈ 5.74 kN/m |
