In general, many color-coated aluminum coils on the market are coated by color steel production lines, not professional color-coated aluminum coil production lines. The products are rough and the materials are uneven.
In addition, many manufacturers now use their own paints instead of the national standard paints (such color-coated aluminum coil paint film has low adhesion and is easy to fade and peel off), and their coating thickness is only 8-10 μm.
The coating thickness of the national standard products should be 15-18 μm,our coating thickness is strictly processed in accordance with the national standard.
