滑动门窗五金主要包括滑轮、滑轨、连接件、固定栓和拉手等。选择时应格外注

The sliding door and window hardware mainly includes pulleys, slide rails, connectors, fixing bolts and handles. When choosing, pay special attention to whether the pulley and the slide rail are matched. <br><br>1. The selection of the pulley is very important. The <br>pulley is an accessory that cannot be ignored in sliding doors and windows. The quality of the pulley is related to whether the sliding doors and windows are easy to use in a large program. The quality of the pulley is determined by the quality of its outer wheels and bearings. The outer wheel is usually made of high-strength wear-resistant nylon or all-copper. The copper pulley is relatively strong, but there is a sound when pulling; the nylon pulley has no sound when pulling, but it is not as wear-resistant as the copper pulley. The bearing must be a multi-layer composite structure with very different materials. Good-quality bearings are made of imported stainless steel, which is tightly installed. When sliding, the feel is soft and there is no noise; some higher-grade pulleys can also be adjusted in height to make up for the distance between doors, windows and tracks, so that they are connected more closely. Some of the small pulleys at the bottom of the doors and windows are also equipped with anti-jump devices, which is more safe and convenient to use. <br><br>2. It is also important to choose the matching slide rails <br>. The slide rails used for sliding doors generally have two textures of aluminum alloy and cold-rolled. The steel rail is strong and durable, and the aluminum alloy rail has less noise. Pay attention to the thickness of the track when selecting. If the doors and windows are small in size and light in weight, you can choose smaller tracks; if the doors and windows are heavy in weight, you must choose thicker tracks to ensure safety and durability. The most important thing for a good slide rail is not the material, but the smoothness of the contact surface of the track with the pulley. Some people pay too much attention to the coating of aluminum alloy rails, and even think that the darker the color of the coating, the better. In fact, this is wrong, because if the coating is unreasonable, it will destroy the surface finish of the rail. The most important thing when choosing is to see whether the pulley is smooth and relaxed when the slide rail is pulled, and whether the noise is small.

滑动门窗五金主要包括滑轮、滑轨、连接件、固定栓和拉手等。选择时应格外注意滑轮与滑轨是否配套。<br><br> 1、选好滑轮很关键<br> 滑轮是滑动门窗中不可忽视的配件。滑轮质量的高低，在很大程序上关系到滑动门窗是否好用。滑轮的质量是由它的外轮和轴承的质量决定的。外轮一般多为高强度耐磨尼龙或全铜两种质地。铜质滑轮比较结实，但拉动时有声音；尼龙质地的滑轮拉动时没有声音，但不如铜质滑轮耐磨。轴承必须是多层复合结构，材质也有很大不同。质量好的轴承采用进口不锈钢材料，安装紧密，滑动时手感柔和，没有嗓音；有些更高档的滑轮还可以调节高度，以弥补门窗与轨道之间的距离，使它们连接得更紧密。门窗底部的小滑轮有的还装有防跳装置，使用更安全方便。<br><br> 2、选好配套的滑轨也很重要<br> 滑动门所用的滑轨一般有铝合金和冷轧两种质地的轨道。钢轨结实耐用，铝合金轨道噪音较小。挑选时还应注意轨道的厚度。如果门窗的体积小，重量轻，就可以选用那些小巧一些的轨道；如果门窗的重量重，就要选择加厚型轨道，以确保安全耐用。好的滑轨最关键的不在于材料，而是看它轨道内与滑轮接触面的光洁度如何。有的人挑选铝合金轨道时，过于在意它的镀层，甚至认为镀层颜色越深越好，其实，这是不对的，因为如果镀层不合理，反而会破坏轨道的表面光洁度。挑选时最重要的是看滑轮在滑轨拉动时是否流畅、轻松，噪音是否小。
