Question:

Our home to aluminum alloy doors and windows, so urgent need to know the specifications of aluminum doors and windows

What is this material and material?

Answer:

Aluminum alloy window thickness difference, and now the specification requirements of the main force of the site thickness of not less than 1.4, the door is not less than 2.0, another thermal insulation bridge aluminum window insulation performance better than ordinary aluminum doors and windows
A and B are ordinary doors and windows of the material, 70B seal is better. But now are using insulated bridge, and is the price to be much higher
Aluminum alloy is not the so-called A material and B material of the points, purely nonsense; Aluminum alloy does have good or bad points: the aluminum raw material checks, you can not control the; then you can do is the aluminum wall thickness; Under normal circumstances: aluminum alloy wall thickness --- GB is 2.0 mm wall thickness; aluminum window wall thickness - GB is 1.4 mm wall thickness; These are the standard of engineering; if you are home to their own equipment, that is, retail, are generally non-standard aluminum, wall thickness will be thin; recommendations: the door to 1.5 or more; window in 1.2 or more; ;
