There are also some configuration differences for the broken bridge aluminum door and window equipment. If the configuration is high, it also has a high safety factor. The quality of the heat insulation broken bridge aluminum door and window processing equipment can be determined from the material selection of raw aluminum profiles, aluminum surface treatment and internal processing quality Make a general judgment on the price of aluminum alloy door and window equipment. The following small series introduces three judgment methods for the quality of broken bridge aluminum door and window equipment:

一看用料.优良的铝合金门窗设备所用的铝型材,厚度、强度和氧化膜等,应符合有关的标准规定,壁厚应在1.2毫米以上,抗拉强度达到每毫米157牛顿,屈服强度要达到每平方毫米108牛顿,氧化膜厚度应达到10微米.如果达不到以上标准,就是劣质铝合金门窗设备,不可使用.

Look at the materials. The aluminum profile, thickness, strength and oxide film used for excellent aluminum alloy door and window equipment shall comply with relevant national standards. The wall thickness shall be more than 1.2mm, the tensile strength shall reach 157 Newtons per square millimeter, the yield strength shall reach 108 Newtons per square millimeter, and the oxide film thickness shall reach 10 microns. If the above standards are not met, it is inferior aluminum alloy door and window equipment, Do not use

二看加工.优良的断桥铝门窗设备,加工精细,安装讲究,密封性能好,开关自如.劣质的铝合金门窗设备,盲目选用铝型材系列和规格,加工粗制滥造,以锯切割代替铣加工,不按要求进行安装,密封性能差,开关不自如,不仅漏风漏雨和出现玻璃炸裂现象,而且遇到强风和外力,容易将推拉部分或玻璃刮落或碰落,毁物伤人.

Second, look at processing. Excellent bridge broken aluminum door and window equipment has fine processing, exquisite installation, good sealing performance and can be opened and closed freely. Poor quality aluminum alloy door and window equipment blindly selects aluminum profile series and specifications, processing is shoddy, sawing instead of milling, installation is not carried out according to requirements, poor sealing performance and can not be opened and closed freely. It not only leaks air and rain and glass cracks, but also encounters strong wind and external forces, It is easy to scrape or bump the sliding part or glass, destroy objects and hurt people

三看.在一般情况下,优良断桥铝门窗设备备因生产成本高,比劣质铝合金门窗设备要高30%左右.有些有壁厚仅0.6-0.8毫米铝型材制作的铝合金门窗设备,抗拉强度和屈服强度大大低于有关标准规定,使用很不.

Third, look at the price. In general, the price of excellent bridge broken aluminum door and window equipment is about 30% higher than that of inferior aluminum alloy door and window equipment due to its high production cost. Some aluminum alloy door and window equipment made of aluminum profile with wall thickness of only 0.6-0.8mm have tensile strength and yield strength much lower than the relevant national standards, so it is very unsafe to use

此外,目前加工铝合金门窗设备的个体户较多,他们不懂得铝合金门窗设备的结构特点及其性能.为了降低成本偷工减料,以次充好,产品的隐患较大,一般不宜采用.

In addition, at present, there are many self-employed households processing aluminum alloy door and window equipment. They do not understand the structural characteristics and performance of aluminum alloy door and window equipment. In order to reduce costs, cut corners and shoddy products, the hidden dangers of products are large, so they are generally not suitable for use

选用正规断桥铝门窗设备生产厂家的产品.这里要特别说明一点:现在的标准的型材厚度为1.4mm以上,如果供应商选择的是1.2mm或者1.0mm壁厚甚更薄的材料的话,都是属于不达标的产品,请大家在选购时注意.

Select the products of regular bridge broken aluminum door and window equipment manufacturers. Here we should make a special note: the current national standard profile thickness is more than 1.4mm. If the supplier selects materials with 1.2mm or 1.0mm wall thickness or even thinner, they are all unqualified products. Please pay attention to them when purchasing
