(1) Broken bridge aluminum alloy doors and windows are the most advanced aluminum alloy doors and windows. It is the fifth generation of new thermal insulation and energy-saving doors and windows after wooden windows, iron windows, plastic steel doors and windows and ordinary colored aluminum alloy doors and windows. Its surface can be painted in various colors.
(2) The composition structure of the broken bridge colored aluminum alloy doors and windows combines the environmental protection of wooden windows, the firmness and safety of iron windows and steel windows, and the commonality of thermal insulation and energy saving of plastic-steel windows and doors. Its structure is more complicated than ordinary aluminum doors and windows, and the cost is higher. Ordinary color aluminum does not have heat insulation strips, and it does not heat preservation and does not save energy, but it is only sprayed on the surface.
(3) The section wall thickness of the aluminum alloy doors and windows of the broken bridge strictly follows the national standard. The wall thickness requirements must be between 1.4 and 2.0mm, because the thickness of the wall is related to the assembly technology and the security of the doors and windows. The wall thickness of ordinary color aluminum doors and windows is generally below 1.4mm.
(4) The colored aluminum doors and windows of the broken bridge are made of special corner codes of more than 3mm for corner grouping, and the group corners should be injected with corner glue for sealing. Ordinary doors and windows are only connected by rivets or screws, and their firmness and safety are poor, but the cost is low. And the assembled colored broken bridge aluminum doors and windows will not be a problem for adults to stand and walk around. The technical requirements of the assembled equipment and those assembled by manual on-site operations are far from each other. The special broken bridge aluminum profile and the ordinary aluminum profile are not the same grade and cannot be compared.
a. Profile wall thickness: Generally for home improvement products, most door and window factories choose products with high yield rate, that is, products with relatively thin wall thickness to reduce the cost, 1.3 thickness is lower than the national standard. The national standard stipulates that the thickness of the profile should be greater than or equal to 1.4mm.
b. Insulation strip: The insulation strip is the most critical part of the broken bridge aluminum profile, and PA66 nylon must be used, which is stipulated by the national standard, but at present, many manufacturers in the decoration market use cheap PVC plastic insulation strips, which will seriously Affect product life and safety.
