What are the characteristics of high quality aluminum alloy doors and windows?
Apr 04, 2018

Everything is good or bad, aluminum alloy doors and windows are no exception. Just as high-quality aluminum alloy doors and windows are 30% higher than the inferior aluminum alloy doors and windows because of the relatively low cost of production, the aluminum doors and windows with poor quality are only 0.6-0.8 mm thick. When they are used, their tensile strength is The yield strength will also be much lower than the relevant national standards and the use is very unsafe.

 

High-quality aluminum alloy doors and windows on the use of materials are particular about:

 

High-quality aluminum alloy doors and windows used in aluminum, thickness, strength and oxide film, each one meet the relevant national standards, wall thickness is also more than 1.2 mm, tensile strength of up to 157 newtons per square meter of mm, After that, the yield strength will reach 108 Newtons per square millimeter and the thickness of the oxide film will reach 10 micrometers.

 

For enterprises like our factory who are regular or have production licenses, the products are marked on the obvious parts of their aluminum alloy door and window products, including the manufacturer's name or brand name, product name, product model or mark, and date of manufacture. Or number. On the packaging box will be marked with "moisture-proof", "carefully light" and "upward" words and signs.

 

High-quality aluminum alloy doors and windows in the processing are also particular about:

 

High-quality aluminum alloy doors and windows, processing more sophisticated, installation stress, good sealing performance, switch freely. The blind aluminum display series and specifications displayed in poor quality aluminum alloy doors and windows are manufactured in a rough and shoddy way. Saw cutting is used in place of milling, and installation is not performed as required. The sealing performance is poor, and the switch is uncomfortable, not only leaking air, but also leaking glass. The phenomenon of bursting, and the presence of strong winds and external forces, it is easy to scrape or touch the sliding part or glass, and the formation of a very strong contrast.

 

High-quality aluminum alloy door and window components are firmly connected, and the connection part is sealed and waterproofed with a corrosion-resistant filler material. And because the quality of doors and windows surface directly affects the decorative effect of the entire wall after installation, we must pay attention to the selection of high-quality aluminum alloy doors and windows produced by regular manufacturers.http://www.lihuiroller.com/
