Aluminum Strip
Aluminum Strip refers to relatively narrow aluminum and aluminum alloy coil products, typically produced by slitting from wider aluminum coils or by continuous rolling. The width of aluminum strip is generally less than 600mm, featuring uniform thickness, clean surface, high dimensional accuracy, and neat edges. Our aluminum strip products cover pure aluminum strips, alloy aluminum strips, and various other series, widely used in electronics, automotive manufacturing, HVAC, building decoration, food packaging, and many other fields. It is an essential basic raw material in industrial manufacturing.
