1. Aluminum profile manufacturers-large aluminum profile plants, original materials, production process specifications, strict quality control, processing costs are higher than small manufacturers, processing costs can differ by 2000-3000/ton. Reduced by 2-3 yuan/kg. In recent years In the future, following the level of the industry, the aluminum industry is becoming more and more popular. Sales are also diversified, with huge price disparity. Without knowing the customers, they will only choose industrial aluminum sales companies from the lowest price. This forces some to insist on quality. One company guarantees the sale from lower raw materials and processing costs, and the market disorder is becoming more and more obvious.
2.A kind of chemical composition, mixed with a large amount of waste aluminum, industrial aluminum profiles can greatly reduce the cost, but it will cause the chemical composition of industrial aluminum to be unqualified and severely endanger the safety engineering.
3. Drawings with roughly the same scale of thickness distribution, as well as cross-sectional dimensions, widths, and center holes, but the wall thickness difference is very large, and it can also be appropriately different components, and each price also corresponds to a large distance. In addition, lower The industrial aluminum can reduce some sealing time, reduce the consumption of chemical reagents, and reduce the cost, but the corrosion resistance of materials is greatly reduced. Jiangyin aluminum profile manufacturer.
4. Oxide film thickness-the thickness is not good, the appearance of the aluminum profile is simply rusty and corroded. The thickness of the national standard building and industrial aluminum oxide film should not be less than 10um (micron). Some feature titles, addresses, production licenses, certificates, industrial aluminum The thickness of the profile and the film is 2 to 4um, and some even have no film. According to expert estimates, every reduction in the thickness of the oxide film by 1um can reduce the power consumption of more than 150 yuan per ton of material.
