Aluminum coil series

Aluminum coil, to put it more colloquially, refers to the roll shape of aluminum material, which is a classification of aluminum plates, also known as aluminum coil plates. It is made of aluminum raw material that is rolled by a rolling mill, then trimmed and annealed. Due to different processing techniques, it is further divided into hot-rolled coils and cold-rolled coils.

Aluminum coils are made of different materials, roughly divided into pure aluminum coils and alloy aluminum coils. They have a wide range of uses, and aluminum coils are used for continuous punching molds, which are efficient and cost-effective for customers. Aluminum coils are often seen in fields such as electronic product processing, mechanical parts manufacturing, pipeline insulation engineering, and so on.

Our company uses high-quality aluminum foil as the substrate for color coated aluminum coils, introduces high-tech technology, cooperates with high-performance roller coating processing technology, and combines advanced production technology to effectively control the accuracy and flatness of the board, with uniform color and bright luster. The product has excellent processing performance, durability, acid resistance, alkali resistance, corrosion resistance, powdering resistance, decay resistance, UV radiation resistance, friction resistance, and other characteristics.

Product specification:

A. Thickness 0.036mm -0.60mm;

B. Width 1200mm -1500mm

Product colors: various colors
