The production process of aluminium chequer plate sheet includes raw material preparation, smelting, casting, punching and coloring. Before formal production process engineers must do math about ratios of different metals and additives in accordance with required alloys. In this way, raw materials of a reasonable ratio are well prepared for melting. In melting process the raw materials are placed into the furnace for ablation in accordance with production requirement, during which impurities and gases are separated and removed by degassing and slag removal processes. Melted pure materials are then poured into deep casting wells and get cooled until they become hard aluminium bars of various sizes. The bars are further heated and punched into aluminium chequer plate sheets of desired patterns. This process usually entails heat treatment of force-air hardening and manual aging. The heat treatment degree differs from specification to specification. Some aluminium tread plates are of natural color and others are colored to meet special application needs. No matter whether they will be colored or not, the patterned plates must be anodized to get stronger corrosion resistance. Then they can be colored as required by clients.
Boasting glossy surface, bright colors, strong shock resistance, convenient cleaning and excellent weather resistance, aluminium chequer plate sheet has become a regular material for domestic decoration. It mainly serves as exterior engineering panels and interior decorative panels. There are single-side and double-size aluminium tread plates. The former has only a layer of aluminum alloy sheet on the surface. It has weaker strength and lower price. While the latter has strong corrosion resistant aluminum sheets on both sides, with the front side painted.
