220x80x2.5mm Steel C Profile, Mill Finish
The 220x80x2.5mm steel C profile is a cold roll-formed lipped channel: 220 mm web, 80 mm flanges, 19 mm edge lips and 2.5 mm thickness, 7.81 kg/m. Roll-formed to order in galvanized S350GD+Z275 steel, it is used for solar mounting structures, roof purlins and side rails, and light steel framing. This page shows the size in pre-galvanized strip S350GD+Z275: Z275 zinc coating (275 g/m² in total on both sides), minimum yield 350 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 220x80x2.5 is used for solar mounting piles, rails and bracing, roof purlins and wall side rails, mezzanine joists and light steel framing. Holes and slots 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, S350GD+Z275). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
| Span | Max UDL |
|---|---|
| 2 m | ≈ 31.38 kN/m |
| 3 m | ≈ 13.95 kN/m |
| 4 m | ≈ 7.84 kN/m |
| 5 m | ≈ 5.02 kN/m |
| 6 m | ≈ 3.49 kN/m |
