Chalco aluminum blinds features
Lightweight: Lightweight is the trend of aluminum shutters. Chalco uses high-quality 3000-series and 5000-series aluminum alloys to manufacture aluminum shutters, which ensure that the products have high bending strength while being light in weight.
Strong weather resistance: Chalco aluminum shutters undergo surface treatment processes such as anodizing or powder coating to enhance the appearance and aesthetics while protecting it from severe weather, non-tarnishing and more durable.
Good fire performance: Chalco aluminum shutters generally have good fire performance. Aluminum is non-flammable, resisting fire and reducing the risk of fire spreading.
Beautiful appearance: Aluminum shutters usually have a modern and simple appearance, which can match various architectural styles and interior decoration styles. Its wide choice of colors and finish options such as anodizing or powder coating make it even more attractive.
Points to pay attention to when purchasing aluminum strips and foils for shutters
Surface quality: Defects such as cracks, corrosion, bumps, peeling, perforation, air bubbles, folds, scratches, metal and non-metal indentations, impressions, pine dendrites, straightening roll marks, etc. are not allowed on the surface.
Cutting surface: It should be cut neatly, and cracked edges, ruffles, burrs, edge deformation and waves that affect painting are not allowed.
Coated tape surface quality: no air bubbles, cracks, yellowing, orange peel, fat edges, shrinkage cavities, bottom leakage, color difference, black bars, miscellaneous points (particles), flow marks, knife backs are allowed on the surface of the coated tape Prints, scratches, scratches and other defects.
