Aluminium Cold Rolled Coils

Product Overview

Aluminium Cold Rolled Coils are precision-processed aluminium products manufactured by cold reducing hot rolled coils to achieve tighter thickness tolerances, superior surface finish, and enhanced mechanical properties. R V Metal Corporation supplies aluminium cold rolled coils in a wide range of alloys, tempers, widths, and thicknesses suitable for demanding industrial and commercial applications. Cold rolling improves flatness, dimensional accuracy, and surface consistency, making these coils ideal for downstream processes such as bending, stamping, forming, cladding, insulation jacketing, and fabrication.

Our aluminium cold rolled coils are available in non-heat-treatable and heat-treatable alloy series, offering an optimal balance of strength, formability, corrosion resistance, and lightweight performance. Depending on alloy and temper, these coils provide excellent workability, controlled hardness, and reliable performance in automotive panels, HVAC systems, electrical enclosures, roofing, packaging, appliance manufacturing, and general engineering applications. Coils can be supplied in mill finish or with customized surface treatments, with full traceability and Mill Test Certificates to ensure compliance with ASTM, EN, IS, and other international standards.
