[China Glass Net] Although the window is inconspicuous, but whether it can be used smoothly in people's daily life, is there a way to buy doors and windows when we usually buy it? Let's take a look at it with Xiaobian!
First, select the material of the rail. The track materials currently on the market are different, the slide rails are mostly alloy texture, and some of the slide rails are made of copper. The alloy texture of the slide rails is divided into normal type and thick type, depending on the texture of the door or window to be applied. If the door or window is small in size and light in weight, you can use a smaller track. If the weight of the door or window is heavy, you should choose a thicker track to ensure safety and durability.
Second, the price reflects the quality. The tracks used on doors and windows are mostly alloy textures, but the texture is good and bad, mainly reflected in the workmanship and materials of the slide rails and pulleys. The low-end doors and window slides sold in the market are priced at a few yuan/Yanmi, the mid-range price is more than a dozen yuan/Yanmi, and the high-end price is 30-40 yuan/Yanmi. The thicker the texture of the slide rail, the stronger the stronger the texture. The price is also higher. The price difference caused by the difference in workmanship is more obvious in the sales of the three-fold rail. The three-fold rail has several different materials of zinc alloy, aluminum alloy and iron. Since the three-fold rail is realized by ball rolling between the rail and the rail, the tightness and uniformity between the balls and the rail contact are achieved. It is very crucial. Good quality three-fold rails During the push-pull process, the balls roll evenly and without squeaking and noise. In terms of price, the high-end three-fold rail is priced at around 100 yuan, which is six to seven times that of low-end products.
Later, pay attention to the pulleys that are matched with them. The pulley is a non-negligible accessory in sliding doors and windows. High-quality pulleys can greatly promote the sliding of doors and windows. The quality of the outer wheel and bearing of the pulley determines the quality of the pulley. Most of the outer wheels are made of nylon fiber or copper. The copper pulleys are stronger, but there is sound when pulling. The nylon fiber texture pulley has no sound when pulled, but it is not as wearable as the copper pulley. The bearing material is also very different. The good quality pulley bearing adopts imported stainless steel material, the bearing is installed tightly, the hand feel is soft when sliding, there is no noise, the higher-grade pulley can also adjust the height to make up the distance between the door and the track, so that the door and the door The track connections are tighter. The quality of the small pulleys at the bottom of the doors and windows is also very different. The small pulleys with excellent craftsmanship are light and fast, and some brands of pulleys are equipped with anti-jump devices for safer use.
