Editor: Ronggao intelligent doors and windows

with the promotion of aluminum doors and windows, more and more people are willing to choose aluminum windows. Everyone has his own way to choose aluminum alloy windows, and the standards are very different, and some methods have great fatal points

fatal point 1: pay attention to beauty

many people only pay attention to the variety of designs and colors rather than the internal quality. The double-layer insulating glass and three-layer laminated glass used are much better than ordinary glass. For the thickness of oxide film, it should reach 10 microns. We can scratch the surface of glass profile to see whether the oxide film on its surface can be wiped off. If it can be wiped off, it is good

fatal point 2: the wall thickness of aluminum profile of doors and windows with heavy thickness

should not be less than 1.2mm. The thickness of aluminum alloy door and window profiles ranges from 0.8mm to 1.2mm, and some even exceed 1.2mm. Among them, aluminum alloy doors with a thickness of more than 1.2mm have better strength, and will not deform for 5-8 years under the premise of normal use

fatal point 3: light hardware

hardware accessories are not supporting roles, but the heart of doors and windows. In the materials of aluminum alloy door and window accessories, it is recommended to use die-casting zinc alloy for handle and transmission parts; Aluminum alloy is used for hinges; Hinge shaft and lock point are made of stainless steel, and lock seat is made of zinc alloy or stainless steel; The quality of the pulley is determined by the quality of its outer wheel and bearing. The glass fiber pulley contains roller bearings, which are smooth in pushing and pulling, wear-resistant and durable. The box closed structure is effective in dust prevention, and two anti jump devices ensure safety and reliability during sliding

fatal point 4: light signs

generally, regular manufacturers have production licenses, and obvious parts of products will have signs indicating products, such as whether there is factory name, "QS" logo, product name and ex factory date. When choosing doors and windows, you should first pay attention to the identification of signs, and at the same time, you can ask the shopping guide to show the production license of the brand and some certificates obtained

these four fatal points have become the misunderstanding of many people in purchasing. Purchasing aluminum alloy doors and windows is a kind of knowledge. As long as you are not caught by these four fatal points, your aluminum alloy doors and windows can last longer
