[China Aluminum Network] The aluminum plate is used as the base material of the gusset plate, so a good aluminum plate must be selected for the good gusset plate. Substrate level can be basically divided into: recycling aluminum → ordinary aluminum → aluminum alloys → aluminum magnesium alloy → aluminum magnesium alloy. Among them, recycled aluminum is a poor substrate, commonly known as waste aluminum. The thickness of the substrate in the market exceeds the industrial standard range, and usually it is mostly recycled aluminum. Intuitively, the thickness of the buckle plate made of recycled aluminum is relatively thick, but due to the relatively large amount of impurities, it is easy to corrode and rust, and more importantly, after the installation, the ceiling is easily deformed and sinks. In fact, the buckle is not as thick as possible, and it is irrational for consumers to simply judge the quality of the buckle by their thickness. Only within the scope of industry standards, through the professional process technology and production technology, to ensure that the material is good, the installation effect can be flat to create a beautiful ceiling without distortion. Professional non-deformed aluminum gussets are processed from aluminum, magnesium, manganese three metals, and more use of imported substrates. The magnesium content is higher, about 1.3-1.8%, which is used to increase the elasticity of the substrate, and the manganese content is about 0.1-0.3, which is used to strengthen the substrate steel. At present, the use of Al-Mg alloy aluminum as the base plate is the better buckle. Other ordinary aluminum plates can only increase the thickness to protect the steel, and they are inevitably delicate and have no toughness.
