The cost of aluminium sheet per kg can not be only expressed by the only way of aluminium sheet price per kg, but by aluminium sheet price per sq ft, aluminium sheet price per square metre, aluminium sheet price per ton etc. These phrases indicate aluminium sheet price by two different standards: weight (cost of aluminium sheet per kg, aluminium sheet price per kg, aluminium sheet price per ton) and size (aluminium sheet price per sq ft, aluminium sheet price per square metre). As a matter of fact, either piece of information is sufficient for a supplier to give you a specific offer, for the price of an aluminium sheet is related to the sheet’s alloy grade, surface treatment method, thickness, size and rolling process.
The category of aluminum sheet plate covers such a wide range of alloy series and grades, the ordinary of which are 1050, 1060, 1070, 1100, 1200, 3003, 3004, 3055, 3104, 3105, 5005, 5052, 5083, 5754, 5a05, 2024, 2104, 2a14, 6061, 6082, 6063, 7005, 7075 and so on. 1000 series of aluminium price is the lowest, 3000 and 5000 series higher, and the left three (6000, 7000, 2000) the highest.
Surface treatment methods for aluminium sheets incorporate mill finish, color coating, polishing, anodizing and embossing. Mill finished aluminium sheet price list is the cheapest of all. Color coated aluminium sheets include PE coated aluminum sheet and PVDF coated aluminum sheet, with the latter more expensive. Polished aluminium sheets, also known as mirror finish aluminium sheets, proves to be more expensive than most coated aluminium sheets. Anodized aluminium plates can be of a mirror surface or an ordinary surface, featured by a hard erosion resistant anodizing film on the surface. The anodizing process costs highest of all the methods, thus usually anodized aluminium sheets are the most expensive. Embossed aluminium sheets fall on many patters: five bar, diamond, stucco, ripple, hammer, 3 bar, 1 bar and so on. Those of high anti-slip functions (five bar and 1 bar aluminium sheets, for example) are also called aluminium checker plates or aluminium tread plates. Embossed aluminium plates are second only to mill finish aluminium sheets in the scale of application, and their prices are relatively lower than the other types of plates.
