Granite grain aluminum coil are mainly processed by 3003, 3004, 3005 aluminum alloy, the costing can be PE, PVDF, HDPE and so on. The granite grain aluminum sheet usually applied to outdoor decoration, so the PVDF coating is more useful, and the PVDF coating thickness is higher than 25um. Granite grain color coated aluminum sheet has a wide range of applications, and can be used in building facades, curtain walls, roofs, floors and other fields, as well as in the manufacture of furniture, lamps and other items. Due to its beautiful appearance, excellent performance, and good durability and maintenance, it has been more and more widely used.


The manufacturing process of granite stone coated aluminum coil mainly includes substrate treatment, coating and processing. Among them, substrate treatment is one of the key links, which needs to undergo strict surface treatment and cleaning to ensure strong adhesion with granite and aluminum. The coating process requires the selection of appropriate coatings and processes to obtain beautiful, weather-resistant, corrosion-resistant and other properties. Processing link needs to be cut, bent, drilled and other operations according to specific needs to meet the needs of different designs.


In conclusion, granite grain aluminum coil is a kind of composite material with excellent performance and wide application, which has a good development prospect. If you are interested in this kind of granite color coated aluminum coil product, please feel free to contact us, we have patterns for you to choose, in addition, free sample is ready to send!
