At present, the frame materials of all the wardrobes on the market mainly include aluminum alloy, aluminum-titanium alloy, magnesium-titanium alloy and high-quality color steel. In general, magnesium-titanium alloy and aluminum-titanium alloy have high strength, durability and firm quality to ensure the door. Up to 2.8 meters without deformation, smooth sliding. The carbon steel frame is light in weight and the appearance is painted, and the paint will be stripped or oxidized and rusted for a long time.
The pulley of the closet is divided into the upper wheel and the lower wheel. The upper wheel is the guard wheel, which is used to make the door slide smoothly when pushed in parallel. The lower wheel is divided into hidden wheels, which are made of pure nylon to carry the weight. The semi-circular progressive rolling is the center of gravity through the wheels, so the horizontal line is pushed and pulled. The bearing capacity can reach 200 kg, the wear resistance is high, and the push-pull life can reach more than 300,000 times.
At present, some brands use a set of upper wheels (hanging rails), so that the lower wheel must bear the weight and play a guiding role. The pressure is too large, it will be easily deformed after two or three months, and the service life is not high. The better manufacturers use the upper and lower sets of wheels, the upper rail guide, and the lower rail load, so that the pulley can be better protected, so that the maximum load of the pulley can reach 200 kg, and the service life can be more than 300,000 times.
