Next, I will give you a detailed introduction about the materials of sliding rails for doors and windows. Skills of selecting sliding rails for doors and windows?

1. What are the materials of the sliding rails for doors and windows?

1. Introduction: Aluminum alloy is the top. The so-called nano-track is to extrude plastic profiles with plastic and add nano-scale plastic fillers. By adding anti-ultraviolet additives and toughening agents, the problems of aging and fracture after long-term use are avoided. In addition, the manufacturing process accuracy is easy to control, and the cost is often much lighter than that of aluminum alloy. It is a good choice for middle and low-end markets and customers.

2. There are many kinds of aluminum alloy crawler, and the surface treatment includes oxidation, spraying and electrophoresis. The raw material is primary aluminum alloy, and many cheap aluminum alloy tracks are made of recycled materials. Electrophoresis is the best surface treatment, and the surface is smooth and does not fade.

3. High-quality pulleys are made of plastics modified with superfine fillers and additives. The surface of the product is smooth and burr-free, and the friction and wear resistance are better. Smooth and silent when pulled by hand. The pull ring is made of stainless steel wire and ground by electrostatic vibration, with excellent surface gloss and good texture.

4. Installation code: generally, the thickness of 0.5MM is used for ordinary painting, and the pressure plate is made of recycled plastic, which is easy to rust and damage. Installation specification is the guarantee of track firmness. Steel plates of 1.0MM shall be used, and nylon pressure plates shall be used. The surface is strictly cleaned by pickling \ cleaning \ derusting \ cleaning process, with firm coating and convenient installation.

Second, the skills of selecting sliding rails for doors and windows

1. Most of the tracks used for doors and windows are made of alloy, but the texture is good or bad, mainly reflected in the workmanship and materials of slide rails and pulleys. The price of low-grade door and window slide rails sold in the market is several yuan/linear meter, the middle-grade is more than ten yuan/linear meter, and the high-grade is thirty or forty yuan/linear meter. The thicker the texture of the slide rail, the greater the strength and the higher the price.

2. The price difference caused by different workmanship is more obvious in the sales of three-fold rail. The three-fold guide rail is made of zinc alloy, aluminum alloy and iron. Because the three-fold rail is extended and contracted by rolling balls between rails, the tightness and uniformity of contact between balls and rails are very important.

3. Pulley is an indispensable accessory in sliding doors and windows. High quality pulleys can greatly promote the push-pull use of doors and windows. The quality of pulley outer wheel and bearing determines the quality of pulley. The outer wheels are mostly nylon fibers or all copper, and the copper pulleys are strong, but there is a sound when pulling.

4. When choosing the sliding rails for doors and windows, it is very important for us to choose the materials of the sliding rails, because the materials of the sliding rails sold in the market are different. There are many alloy materials of the sliding rails, and some of them are copper. Alloy slide rails are divided into ordinary and thickened types, depending on the texture of applicable doors or windows. 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. This is something we must remember.

The above information is about the materials of sliding rails for doors and windows and the skills of purchasing sliding rails for doors and windows. I will introduce it to you in this issue. It's over. I believe the above information can help you.
