Z180×59×15×4 mm Steel Z Profile — S450GD+ZM Magnelis
The 180x59x4mm steel Z profile is a cold roll-formed lipped purlin: 180 mm web, 59 mm flanges with 15 mm edge lips and 4 mm thickness, 9.38 kg/m. Roll-formed to order in Magnelis S450GD+ZM steel; Z purlins can be lapped at supports to form continuous roof and wall purlin lines. This page shows the size in Magnelis strip S450GD+ZM: zinc–aluminium–magnesium coating, ZM310 or ZM350 coating mass, minimum yield 450 MPa.
Made to Order — Roll Formed

Applications & Usage
Z 180x59x4 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. Magnelis is often specified for solar mounting structures and agricultural buildings in corrosive environments. 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, S450GD+ZM310 / ZM350). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
| Span | Max UDL |
|---|---|
| 2 m | ≈ 37.67 kN/m |
| 3 m | ≈ 16.74 kN/m |
| 4 m | ≈ 9.42 kN/m |
| 5 m | ≈ 6.03 kN/m |
| 6 m | ≈ 4.19 kN/m |
