What months is the peak season for aluminum alloy doors and windows?

In March, April, May and1October next year, aluminum will be needed in1October because many projects will be completed before winter. Demand is also very strong. If you want to buy aluminum alloy windows, you need to pay attention to several aspects: 1. The aluminum profile, thickness, strength and oxide film used for high-quality aluminum alloy doors and windows shall conform to the relevant national standards, the wall thickness shall be above 65438 0.2 mm, the tensile strength shall reach 65438 057 Newton/mm2, and the yield strength shall reach 65438 008 Newton/mm2. For example, the appearance of doors and windows is also a key link. There is an artificial oxide film on the surface of aluminum alloy doors and windows, which forms a composite film after coloring. This composite film is not only corrosion-resistant and wear-resistant, but also has a certain fire-proof function and high gloss. Generally speaking, the price of high-quality aluminum alloy doors and windows is about 30% higher than that of inferior aluminum alloy doors and windows because of the high production cost. I hope my answer is helpful to you.
