[ Chinese wardrobe network ] 1. Purchase note 1: Profile
There are two types of practical profile substrates: one is aluminum alloy and the other is plastic steel. Due to its light weight and high strength, aluminum alloy is a high-grade material for sliding door substrates. Has gradually replaced plastic steel products. The aluminum alloy itself is divided into ordinary aluminum-magnesium alloy and smaller aluminum-magnesium alloy for special aviation. Because aluminum-magnesium-titanium-silicon alloy has higher strength and smaller weight. Therefore, it is favored by consumers, but the cost is several times that of ordinary aluminum-magnesium alloy. When looking at the profile, not only pay attention to the substrate, but also observe its surface treatment. Advanced surface treatments include anodizing, electrophoretic coating carbon coating, etc. These processes have higher hardness and aesthetics than simple spraying and plating. The electrophoretic coating used by KD in the United States has a film thickness of 20 microns and the adhesion reaches the international highest standard of 0, which has unparalleled scratch resistance.
2. Purchase Note 2: Top and bottom rails
At the time, try to choose the top and bottom rails of the same material as one material, thinking that the top bottom rail is the load-bearing part. To withstand repeated friction, the top and bottom rails must have high strength and wear resistance. The top and bottom rails are made of aluminum-magnesium-titanium-silicon alloy with higher strength, strong resistance to deformation and longer service life.
3. Purchase Note 3: Top Wheel
The top and bottom wheels are important accessories for sliding doors. It is necessary to pay attention to the selection of high-quality bearing pulleys. The outer part of the bottom wheel is made of FRP material, which has the characteristics of high strength, wear resistance and low noise. Using push-pull more than 100,000 times, the wheel body is treated with three-degree polishing and plating, never rusting.
