Profile Section
360x98x3mm Steel C Plus Profile, Mill Finish
The 360x98x3mm steel C Plus profile is a cold roll-formed channel with double edge lips: 360 mm web, 98 mm flanges, 25 mm lips with a return and 3 mm thickness, 14.19 kg/m. Roll-formed to order in galvanized S420GD+Z275 steel, it is used where a heavier purlin, column or beam section is needed. 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.
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
C+ 360x98x3 is used for load-bearing purlins and facade rails, and as columns and beams in warehouses and light steel buildings. Holes can be punched to your drawing. 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 | ≈ 107.12 kN/m |
| 3 m | ≈ 47.61 kN/m |
| 4 m | ≈ 26.78 kN/m |
| 5 m | ≈ 17.14 kN/m |
| 6 m | ≈ 11.90 kN/m |
