The advantage of anodized aluminum sheet rolls is that they do not change color after long-term use. Many aluminum products are blackened and discolored when exposed to humid air and suitable for outdoor use for a long time. The reason is that the aluminum will be oxidized by the outside air in the natural environment, and the surface will be formed. The oxide film with uneven thickness, because the oxide film thickness is uneven, there will be color difference, although it will not continue to oxidize inside, but the appearance is not very good, while the aluminum oxide roll is artificially generated in advance on the surface of the aluminum roll to various thicknesses The oxide film does not change color after long-term use. Alumina coil is the product of aluminum coil after oxidation.

Henan Signi Aluminum Industry Co., Ltd. provides alumina coils, adopting continuous anodizing process of coils, and provides alumina coils of various specifications and models, alumina plates, laminated alumina plates and aluminum coils, and is a supplier of alumina coils with stable quality and reasonable prices. . Provide various thicknesses of aluminum oxide rolls, aluminum oxide plates, the surface can be filmed, the thickness can be customized, can be cut to length and flatten aluminum plates of various sizes, and cut aluminum strips of various widths, provide aluminum oxide rolls, anodized aluminum sheet coils, and film Welcome to inquire for various products such as alumina rolls.

It can provide 1060 anodized aluminum sheet coils, 3003 alumina coil, 5052 anodised aluminium sheet coils and other materials of alumina coil products. Hot-rolled aluminum coil is used as the raw material. The surface of the oxidized aluminum coil has no color difference, no watermark, and no fixture marks, which is suitable Used in hardware appliances, chassis cabinets, electrical enclosures, architectural decoration and other industries

 Anodised aluminium sheet rolls have good anti-rust, anti-corrosion, anti-fouling, anti-static and other effects. Our company adopts the coil oxidation process, which can better ensure that the surface texture of the alumina coil is consistent, there is no color difference, no water ripples, and no water mark surface defects. We provide alumina coils and anodised aluminum sheet coils of various thicknesses. Surface can be filmed
