The difference between steel and aluminum alloy profiles
The quality of steel doors and windows is very difficult to identify, steel doors and windows of the steel liner standards should be GB 1.2mm, but you buy after the identification of its compliance, it is very difficult. But the broken bridge aluminum doors and windows in the identification of the quality is relatively easy, broken bridge aluminum window wall thickness standard is 1.4mm, the door profile thickness of 1.6mm, these thickness is on the surface can be Depending on the measured, so after the identification on the purchase, it is very easy. Another point to note is that no matter what kind of profiles you choose the doors and windows, we must focus on the strength of the manufacturers and workers of the technology, doors and windows performance is playing a good effect, depends entirely on the manufacturer's design, measurement , Installation and production. No matter what kind of profiles of doors and windows, to become a good door and window, are three points for seven installs. Obviously, the installation of technology is much more important than the type of selection.
Aluminum doors and windows better, but I said that this aluminum alloy is not an ordinary aluminum alloy, its full name is called "heat insulation bridge aluminum" profile. This kind of aluminum alloy doors and windows profiles, it is more complex than ordinary old aluminum alloy structure, thickness and strength and finish much higher than the old aluminum alloy doors and windows profiles, his structural design more scientific and efficient for the family to save energy , With good insulation noise, cold insulation properties, not easy to deformation, discoloration, corrosion resistance and rugged than plastic steel profiles are several times higher. In the decoration of doors and windows, for steel windows and broken bridge aluminum alloy doors and windows of choice, broken bridge aluminum doors and windows of the cost is much higher than the steel doors and windows.
Plastic windows are easy to weather, aluminum alloy will not. If you want to be insulated when you do windows with double glass
