1. Choosing a pulley is critical. The pulley is a non-negligible accessory in sliding doors and windows. The quality of the pulley, in a large program related to sliding doors and windows is easy to use. The quality of the pulley is determined by the quality of its outer wheels and bearings. The outer wheels are generally made of high-strength wear-resistant nylon or copper. The copper pulley is relatively strong, but there is a sound when it is pulled; there is no sound when the nylon texture pulley is pulled, but it is not as good as the copper pulley. The bearing must be a multi-layer composite structure and the material is also very different. Good quality bearings are made of imported stainless steel, tightly mounted, soft to the touch when sliding, and have no squeaks; some of the more upscale pulleys can also adjust the height to compensate for the distance between the door and the window and the track, making them more tightly connected. Some of the small pulleys at the bottom of the doors and windows are also equipped with anti-jump devices, which are more safe and convenient to use.
2. It is also very important to choose the supporting rails. Slide rails used for sliding doors generally have two textures of aluminum alloy and cold rolling. The rails are strong and durable, and the aluminum alloy tracks have less noise. The thickness of the track should also be taken into consideration when selecting. If the doors and windows are small and lightweight, they can use those small tracks; if the doors and windows are heavy, they must choose thicker tracks to ensure safety and durability. The key to a good slide is not the material, but how it looks in the track's contact surface with the pulley. When some people choose aluminum alloy tracks, they care too much about its coating, and even think that the darker the coating is, the better. In fact, this is wrong, because if the coating is unreasonable, it will destroy the track surface finish. The most important thing in selection is to see if the pulley is smooth and easy to pull when the slide rail is pulled and the noise is small.
