Color coated aluminum coil performance application information introduction

Date: 2019-05-18 09:28
Color coated aluminum coil
Pre-coated aluminum (pre-coated aluminum coil), produced with aluminum or (aluminum coil) and treated with a color coating. In common sense, there are two prefabricated aluminum coils - PVDF and PE, which are widely used in aluminum sheets, aluminum sheets, aluminum honeycomb panels, aluminum ceilings, shingles, scraps, pop-up tops, and electronics. Precoated aluminum coils are the most popular material compared to other sections because of their superior properties. First of all, the property is very stable. Secondly, the surface is corrosion-resistant, and the special treatment can be up to 30 years after Mingtai. Finally, when the volume is fixed, the density is the lowest of the metal materials.

As each type of coating surface coating, coated aluminum coils can be classified into polyester (PE) coated aluminum coils, fluorocarbon (PVDF) coated aluminum coils and epoxy coated aluminum coils.
Depending on the thickness of the coating, it can be divided into single-coated aluminum coils (4-20 microns); double-coated aluminum coils (25 to 28 microns) and three-layer coated aluminum coils (35-38 microns).
Color coated aluminum coils are widely used in roofing and cladding systems, ceiling systems, curtain wall panels, shutters, gutters, composite panels, cans, household appliances panels and embossed aluminum coils.
