Profile Section
400x94x4mm Steel C Plus Profile, Mill Finish
The 400x94x4mm steel C Plus profile is a cold roll-formed channel with double edge lips: 400 mm web, 94 mm flanges, 25 mm lips with a return and 4 mm thickness, 19.67 kg/m. Roll-formed to order in S500 steel, it is used where a heavier purlin, column or beam section is needed. 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
C+ 400x94x4 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. 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). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
| Span | Max UDL |
|---|---|
| 2 m | ≈ 189.05 kN/m |
| 3 m | ≈ 84.02 kN/m |
| 4 m | ≈ 47.26 kN/m |
| 5 m | ≈ 30.25 kN/m |
| 6 m | ≈ 21.01 kN/m |
