Job work: your coil rolled into sheets and purlins

Profiles we can roll on your coil

• 2 Rib and 3 Rib trapezoidal roofing and cladding sheets, 1,000 mm effective cover from a 1,060 mm strip, up to 12 m long.
• 4 Rib standing seam, rolled at your site from your coil in lengths up to 300 m.
• Deck profile from CRCA or GI coil, 0.6 mm and up.
• C purlins from 1.0 to 3.0 mm and Z purlins from 1.2 to 3.0 mm, web 80 to 300 mm, punched to your drawing, up to 12 m.
• Flashings, ridges, gutters and trims folded from your sheet or coil.
• Crimp curving of rolled sheet for curved roofs.

Slitting is done here. If your coil is a mill width we slit it to the 1,060 mm strip the rib profiles need, or to the strip width for the purlin section, and the trim is weighed, then returned to you or credited, as agreed for each job.

What to send us before the coil

• Coil specification: base metal thickness and total coated thickness, coating class (AZ150, Z275 or similar), steel grade, and the mill test certificate.
• Coil width and weight, and the number of coils.
• The profile you want, and for purlins the section drawing with the punching.
• The cutting list: lengths and quantities, with the bay or position marked if you want the bundles labelled.
• Where the finished material goes, and whether you collect or we deliver.

Galvalume and colour coated coil should arrive with its protective film intact and the coil eye clear. We check every coil on arrival and tell you before rolling if it is out of round, edge-damaged or outside the thickness on the certificate.

How job work is priced

Conversion is charged per kg of finished material, by profile, thickness and quantity. Rates start from ₹0.25 per kg, subject to material, profile and quantity, and the actual figure also depends on the lot size and the punching. Slitting, crimp curving and delivery are separate lines. GST at 18% is extra.

Minimum lot: we roll from one full coil upwards. Below that the set-up time on the line costs more than the rolling, and we will say so rather than quote a rate that surprises you.

What we cannot do on job work

We cannot certify coil we did not buy. The mill test certificate you give us is the one that goes out with the finished sheets, and our inspection report covers the profile dimensions and the cut lengths, not the coating or the steel grade. If the coil turns out to be under gauge, the sheets will be under gauge, and we tell you as soon as we measure it.
