1. Broken bridge aluminum door and window profile series
Want to know why the price of broken aluminum doors and windows is so big, first we have to understand the specifications of aluminum doors and windows of broken bridges:
The price of broken aluminum doors and windows is different, and the price is also different. Even if the same brand of broken aluminum doors and windows, different series, the specifications are different, the price is also different. Based on 60 series casement windows, the wall thickness is 1.4mm , and there are also less than 1.4mm , 1.2mm or even 1mm . These are unqualified according to the national standard. The aluminum doors and windows of the broken bridge must be at least 1.4mm . Meet the standard.
The aluminum profile of the broken bridge is also the difference between the recycled aluminum and the pure aluminum ingot. The recycled aluminum refers to the aluminum alloy door and window profile which is re-melted after the waste aluminum is recovered, and the strength is not up to standard, the service life is short, the deformation is easy, and the price is also Cheap.
　　 2 , broken aluminum doors and windows hardware
The hardware components used in the aluminum doors and windows of the broken bridge also affect the price to a certain extent. The quality of the hardware is still largely related to the quality of the window and cannot be ignored.
　　 3 , insulating glass
The regular broken aluminum doors and windows are made of double-layer hollow float glass. The thickness of the glass is not less than 5mm , which is the “five centimeter†glass that people often say in the mouth. There are also some cheap broken aluminum doors and windows. It is a negative "five centimeter" glass. In fact, it is a glass with a thickness of less than 5mm . This can not guarantee the quality. Because the thickness between 3mm and 4.9mm can be collectively referred to as "negative five centimeter" glass, the price in the middle can be seen. .
　　 4 , sealing the strips and glue
The sealing of aluminum doors and windows of broken bridges is very good. The big reason is because of the existence of sealing strips. These strips constitute several sealing procedures that we often say. According to different brands, the number of sealing layers is also more or less. The EPDM strips used in Langjialong doors and windows are good in elasticity, green and environmentally friendly, and the inferior PVC strips have a pungent odor, which is easy to harden and become brittle. The two are easy to distinguish, and the price gap is also very large.
　　 5 , anti-mosquito anti-theft diamond screen
Most of the aluminum doors and windows of the broken bridge will be equipped with diamond screens, and the gauze of the diamond screen has many materials: manganese steel, 201 stainless steel, 304 stainless steel ; the so-called manganese steel is iron mixed with manganese and carbon, and has a fixed lattice. 201 stainless steel is composed of 17Cr-4.5Ni-6Mn-N , which is a substitute steel for Ni steel and 301 steel. After cold working, it has magnetic properties and is used in railway vehicles. 201 is high in manganese , the surface is very bright and dark, and the manganese is high and easy to rust.
　　 304 is imported stainless steel plate, which is the most widely used stainless steel and heat resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc. 304 contains more chromium , the surface is matte , no rust . The two are put together to compare. The most important thing is the different corrosion resistance.
