Teach you how to choose high-quality cast aluminum doors (1)

Look at the material and details of the product. No matter what kind of door it is, it is very important to be strong, and this stability is mainly determined by the material of the door. Cast aluminum doors are thick and heavy. Generally, a door leaf (1m*2.3m) weighs about 150kg. Without hard steel, it is difficult to support the entire door.

Currently on the market The door frame and door leaf edging materials include hot-dip galvanized steel plate, cold-dip galvanized steel plate, cold-rolled plate, stainless steel plate, aluminum profile, etc., and Ouhua Zundi cast aluminum doorThe material used is hot-dip galvanized steel plate (SECC steel plate). This steel plate not only has good hardness and strength, but also It is resistant to oxidation and corrosion and has strong paint adhesion; cold-dip galvanized steel plates and cold-rolled plates themselves will rust; stainless steel plates have poor paint adhesion; aluminum profiles have insufficient hardness and strength and are prone to sagging and deformation.

The thickness of the cast aluminum plate on the facade is not less than 8mm. Generally, there will be no problem with the resistance performance. The key to its quality lies in its structural components. From the keyhole, you can check whether there are black spots on the exposed aluminum plate. If there are, It means that the purity is not enough. It is definitely not processed by standard alloy aluminum ingots or mixed with recycled waste aluminum. It will soon become oxidized. Welding and corrosion, and then check whether each welding and connection point of the product is smooth and traceless; when the door is closed, whether the lines left on the door are consistent, whether there is any gap at the joint between the door leaf and the door frame; whether the surface paint is even and has There are no grains of sand, its three-dimensional effect and smoothness, etc. The advantages and disadvantages of the product can be determined from these details.
