Aluminium Coil Manufacturers

As everyone's requirements for raw materials are getting higher and higher, aluminum coils are gradually replacing galvanized steel sheets due to their good heat insulation and anti-rust effects. More sales will start with raw materials, processing technology, etc., resulting in uneven quality of aluminum materials on the market. If you want to buy better quality products, you need to pay attention to the following points.

1, Regarding the weight calculation, the aluminium coil manufacturers calculate the aluminum coil weight according to the net weight, that is to say, the packaging, winding core and other accessories are not included in the weight calculation. Since many raw materials are sent directly to the construction site, there is no way to weigh them on site, which gives unscrupulous merchants the opportunity to exploit loopholes, and they will lie about part of the weight in order to obtain greater profits. For those cases where there is no way to weigh on site, you can look at the logistics scale sheet of the freight, and roughly subtract the gross weight of wooden pallets, turnover materials, roll cores, etc. according to the order quantity, and the rest is the net weight of the product.

2, Quenching is a very important process in the processing of aluminum coils, and many manufacturers will omit the step of quenching in order to save costs. In this way, the processed aluminum is relatively hard, and we often need to correct it during construction. If the product is bent, if the softness of the product is not enough, it will be prone to breakage, etc. Therefore, when purchasing products, you must buy those materials that have been quenched. Although their prices will be higher, but in this regard money must not be saved.

3, Do compare prices of aluminum coil, and take a more suitable price, but don't be greedy for cheap. The current aluminum coils are mainly 1060 and 3003, of which 1060 is pure aluminum, and 3003 is an aluminum alloy material, so the price of 3003 aluminum coil is higher than that of 1060 aluminum coil. If there is a requirement for the thickness when purchasing aluminum coil, then you must pay attention to the measurement when receiving the goods, because many aluminum coil manufacturers will privately use low-thickness aluminum instead in order to save money under the premise of reducing prices. The difference is not big, but the difference in usage effect is huge.

4, Air oxidation is a very common problem during the transportation and storage of aluminum coil. Air oxidation is generally caused by the urine-alkali or gray-black damaged surface that is similar to fire on the surface after the product touches water or rain. After the aluminium coil manufacturers deliver the product, be sure to check the package and surface when receiving the goods, and store them in a dry warehouse.
