220x80x3.5mm Steel C Profile, Mill Finish
The 220x80x3.5mm steel C profile is a cold roll-formed lipped channel: 220 mm web, 80 mm flanges, 23 mm edge lips and 3.5 mm thickness, 10.98 kg/m. Roll-formed to order in Aluzinc steel, it is used for solar mounting structures, roof purlins and side rails, and light steel framing. This page shows the size in Aluzinc: steel strip with an aluminium–zinc alloy coating. The steel grade is confirmed in the quotation.
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.
