It is very important to push and pull the door and window hardware. How to choose pulleys and tracks?

Sliding doors and windows are widely welcomed by consumers because of their small occupation space, beautiful appearance and convenient use. Compared with traditional doors and windows, the service life of sliding doors and windows mainly depends on the service life of door and window hardware. Choosing good hardware can not only make sliding doors and windows run normally and smoothly, but also ensure that doors and windows are more durable.

Pulley is an indispensable accessory in sliding doors and windows, and the quality of pulley greatly affects the sliding quality of doors and windows. A good set of pulleys should be stable, safe and noiseless when used. The quality of pulley outer wheel and bearing determines the quality of pulley. The outer wheels are mostly nylon fibers or all copper. The copper pulley is strong, but there is a sound when pulling; There is no sound when nylon fiber pulley is pulled, but it is not as wear-resistant as copper pulley. Bearing materials are also very different. Pulley bearings are made of imported stainless steel with high quality. The bearing is tightly installed, so it feels soft and noiseless when sliding. More advanced pulleys can also adjust the height, make up the distance between the door and the track, and make the door and the track more closely connected.

High-quality sliding door is mainly reflected in the design and manufacturing level of its pulley system and the supporting track design. The close cooperation of pulley track can effectively reduce the noise when pulley slides and prolong the service life of sliding doors and windows for at least ten years. The track matched with the pulley is also important for the use of sliding doors. There are generally two kinds of rails for sliding doors: cold-rolled steel rails and aluminum alloy rails. Consumers may generally think that rail is more durable than aluminum alloy rail, and the thicker the rail wall, the better. Actually, it's not. High-quality sliding door hardware is embodied in the perfect combination of track and pulley, not just a certain part. The track must have a perfect curvature and match the pulley, and then the material problem. The track materials sold on the market now are all different. Most of the slide rails are alloy, and some of them are steel.

In the choice of rail and aluminum alloy track, consumers should not unilaterally think that rail must be better than aluminum alloy track. A good crawler determines the strength design of the crawler and the smoothness of the contact surface between the crawler and the pulley. A good aluminum alloy crawler is superior to the rail in noise resistance. Professionals remind consumers that the material of the slide rail should be determined according to the texture of the applicable door or window. If the door or window is small in size and light in weight, you can choose a smaller track. If the door or window is heavy, you should choose a thickened track to ensure safety and durability.
