If you have sliding doors and windows in your home, you must purchase door and window rails. Since the door and window rails are sliding doors and windows, they usually come with grooved or curved rails, which are usually equipped with ball bearings to facilitate the sliding of doors and windows. Door and window rails are not only good quality, but also directly affect the use of doors and windows in daily life, the following I take aluminum alloy doors and windows as an example, the introduction of door and window rails to buy tips, see how to buy aluminum alloy door and window sliders.
How to choose aluminum alloy door and window sliders?
Purchasing skills: choose the matching pulley
Pulley and slide rail are indispensable accessories for sliding doors and windows, the quality of the quality of the decision to push and pull the doors and windows of the use of experience. General pulley outer wheel and bearing quality to determine the quality of the pulley. Currently on the market pulley outer wheel is mostly nylon fiber or copper texture, copper pulley is stronger, but pulling the sound, and nylon fiber texture pulley pulling no sound, but not as wear-resistant as the copper pulley.
The same is true for the bearings, which are made of very different materials. Good quality pulley bearings are made of imported stainless steel, bearing installation close sliding feel soft, and no noise. High-grade pulleys in addition to good quality can also adjust the height, can make up the distance between the door and the track, so that the connection between the door and the track will be more closely.
Doors and windows at the bottom of the small pulley quality of workmanship is also very concerned about the craftsmanship of the small pulley pull up will be very light, some brands on the market pulley is also equipped with anti-skipping device can make the use of more secure.
Purchasing tips two: look at the material of the slide
Aluminum windows and doors are made of extruded aluminum alloy profiles for the frame, stile, fan material production of windows and doors, so the choice of material for the slide should be consistent with the aluminum alloy material. Currently on the market, although the material of the door and window slider varies, but still more than alloy texture-based, there are some sliders are made of copper. The alloy texture of the slide according to the thickness is divided into ordinary and thickened type, in the selection of everyone according to the texture of their own doors and windows to determine.
For example, if the size of the door or window is relatively small and the quality is light, you can buy some compact door and window tracks. If the weight of the door or window is heavy, then it is best to choose a thicker type of track, so that both safety and durability.
Purchasing tips 3: look at the price of the slide
The price of the door and window slider largely determines the quality of its strengths and weaknesses, mainly from the slide, pulley workmanship and materials reflected. For example, the market of low-grade door and window slider, priced at about a few dollars per meter, mid-range door and window slider price of more than ten yuan per meter, high-grade door and window slider price is to be in the thirty-forty yuan per meter, it can be said that the thicker the texture of the slider is the more solid, then the higher the price is.
The price of different workmanship will also have differences, especially in the sales of tri-fold rail is more obvious. The material of tri-fold rail has zinc alloy, aluminum alloy and iron, etc. The working principle is to realize the expansion and contraction through the ball rolling between the rail and the track, so the tightness and uniformity between the ball and the contact with the track is very critical.
High-quality tri-fold rail in the push and pull process, the ball rolling is uniform and consistent, there is no sense of astringency and noise. High-grade tri-fold rail market price is about one hundred dollars, six to seven times higher than the low-grade slide rail.
