Aluminium Sheets & Coils

Aluminium Sheets & Coils

Aluminium Alloy Sheets and Coils are widely used in various industrial and commercial applications due to their excellent combination of light weight, strength, corrosion resistance, and formability. Manufactured using premium-grade raw materials, these alloys are available in different tempers and thicknesses to meet diverse application needs.

Aluminium alloy sheets and coils exhibit superior surface finish, high reflectivity, and excellent thermal and electrical conductivity. They are easy to fabricate through processes such as welding, machining, and forming, making them ideal for use in industries such as automotive, aerospace, construction, marine, and electrical.

Available in various grades such as 1050, 1055A, 1100, 4026, 5052, and 8030, each alloy offers distinct mechanical and chemical properties tailored for specific performance requirements. These sheets and coils are supplied in standard and custom dimensions with mill finish or surface coatings as per customer specifications.
