First,look at the thickness. The thickness, strength, and oxide film thickness of the high-quality checkered plate should conform to the national standards: aluminum plate thickness ≥1.2mm, tensile strength ≥157N/mm2, yield strength ≥108N/mm2, oxide film Thickness ≥ 10 microns. If it fails to meet the specifications, it is a defective board.
Second, look at processing. The patterned plates produced by regular large factories are made of exquisite materials, the surface is bright and bright, the patterns are clear and regular, the aluminum plates are flat, and the appearance is free from oil stains, scratches, breaks and other defects; while the patterned aluminum plates produced by small factories use scrap aluminum as materials, The appearance is dull and dull, the markings are not clear and irregular, the board surface is not flat, the performance is unqualified, and the quality is poor.
Third, look at the price. Patterned aluminum plates are divided into two types: pure aluminum and alloys, and their prices are naturally different. The processing cost of patterned aluminum plates produced by regular manufacturers is several thousand yuan per ton, and the price of alloys is higher than that of pure aluminum. When an enterprise is acquiring, it should not be compared with the price alone. If you buy substandard products, it will be too late to regret it.
Fourth ,look at the service. From the production line of the manufacturer to the workshop of the enterprise, the center has to go through many links of packaging, loading, transportation, storage, and unpacking. The striped aluminum plate will inevitably show defects such as oxidation and scratches. The large-scale and efficient suppliers will provide users with good service. Provide return and exchange services to solve worries for users.
In fact, aluminum tread plate is processed by embossing equipment. For example, our common five-rib decorative aluminum plate is processed by embossing equipment.
The production process of patterned aluminum plate can be divided into two ways. One is the old-fashioned production equipment with various equipment processing, the aluminum plate is first opened, and then put one by one into the embossing equipment for pressing. The pattern trend of each piece of patterned aluminum plate is different, and the production capacity is low.Another production process is continuous production, which is directly pressed by coiler + embossing equipment on the coil, so that the pattern trend of the same batch of pattern aluminum plate is completely consistent, with high yield.
After rolling, there will be a variety of patterns on the surface of the aluminum plate. Of course, this has not been completed, and subsequent processing, such as cutting, annealing, rectification of flatness, etc., is needed. This is how the decorative aluminum plate is produced.
