Aluminum coil is a coiled metal sheet made primarily of aluminum or aluminum alloys through processes such as casting, hot rolling, and cold rolling. It is a fundamental product in the aluminum processing industry, delivered in coil form, but can also be flattened for use.
Aluminum coil thickness typically ranges from 0.1mm to 10mm, and width varies from 200mm to 2800mm, depending on the specific process and requirements.
Color Coated Prepainted Aluminum Coil is a colored metallic composite material made from aluminum alloy coils as the base material. After surface pretreatment (such as chromating), an organic coating (such as polyester or fluorocarbon) is applied using a roller coating process, followed by high-temperature baking and curing. Color Coated Prepainted Aluminum Coil is widely used in construction, electronics, packaging, and home appliances. Typical applications include aluminum composite panels, industrial building roofs and walls, aluminum ceilings, and electronic product casings.
