Mill Finish Aluminum Coil 1050 1060 3003 Alloy Aluminum Coil for Roof Insulation

Our mill finish aluminum coil is produced by hot rolling and cold rolling process, raw aluminum ingot as raw material without any color coating. We supply full series aluminum alloys including 1000 series pure aluminum (1050,1060,1070), 3003 anti-rust aluminum coil, 5052 magnesium aluminum coil. Strict thickness tolerance control, flat rolling surface without scratches, oil spots or deformation.

The aluminum coil features excellent malleability, oxidation resistance, light weight and easy deep drawing processing. It can be further slitted into narrow aluminum strip, cut into flat aluminum sheet, or processed for embossing, painting. We can customize coil inner diameter 300/400/505mm, outer diameter as client’s demand, paper core or steel core inside.

FAQ

Q1: What alloy aluminum coil do you have in stock?

A: Regular stock: 1060 pure aluminum coil, 3003 anti-rust aluminum coil. Other alloys like 1050,5052 can be customized within 7-10 working days.

Q2: Can I get narrow width small coil after slitting?

A: Yes, our slitting machine can cut width from 20mm to 1600mm, small mini coil acceptable for trial order.

Q3: What’s the minimum order quantity?

A: Stock aluminum coil MOQ 1 ton; customized alloy MOQ 5 tons.

Q4: Is the aluminum coil anti-rust without coating?

A: 3003/5052 alloy has natural anti-corrosion performance; 1000 series pure aluminum needs surface coating if used in humid coastal environment.

Q5: How long is production lead time for customized size?

A: Stock goods ship within 3 days; customized thickness/alloy lead time 7-12 days.
