1. Product Introduction

DongChuan color coated aluminum coil is used for manufacturing aluminum material of aluminum alloy roof gutter and drain pipe. 3105H24 and 3003 H24 aluminium alloy are adopted. Both sides of aluminium roll are coated with PET paint through roller painting.  Film thickness of surface is 25- 28 um; and film thickness of the back is 15 - 18 um. Besides, the color is durable.

It is easy to bend and weld aluminum coil in machining process due to its good mechanical properties and rail pressure molding. Besides, it has become a kind of ideal raw material of domestic and foreign aluminum roof gutter (sink) and drain pipe factories.
