(1) Broken bridge aluminum alloy doors and Windows are the most advanced aluminum alloy doors and Windows, which is the fifth generation of new thermal insulation 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 a variety of colors.
(2) The composition structure of the broken bridge color aluminum alloy doors and Windows is combined with the environmental protection of wooden Windows, the firm safety of iron Windows and steel Windows, and the commonalities of thermal insulation and energy saving of plastic steel doors and Windows. Its structure is more complex than ordinary aluminum doors and Windows, and the cost is higher. Ordinary color aluminum does not have heat insulation strip, heat preservation and energy saving, and it is only sprayed on the surface.
(3) The wall thickness of the broken 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 wall thickness is related to the assembly technology and the solid security of the composition of the door and window. The wall thickness of ordinary color aluminum doors and Windows is generally below 1.4mm.
(4) The broken bridge color aluminum doors and Windows are assembled with a special corner code of more than 3mm, and the corner of the group should be injected with corner glue to seal. Ordinary doors and Windows are only connected by pulling rivets or screws, and the degree of firm safety is poor, but the cost is low. And assembled color broken bridge aluminum doors and Windows adults standing on the walk will not have a problem. The technical requirements of the assembly of complete sets of equipment and the assembly of manual field operation are far from each other. Special broken bridge aluminum profiles and ordinary aluminum profiles are not the same grade and can not be compared.

How to judge the advantages and disadvantages of broken bridge aluminum profiles?
a, profile wall thickness: generally do home improvement products, most of the door and window factories choose products with high material yield, 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, heat insulation strip: the heat insulation strip makes the most critical part of the broken bridge aluminum profile, must use PA66 nylon, which is stipulated by the national standard, but at present, many manufacturers on the decoration market use cheap PVC plastic heat insulation strip, which will seriously affect the service life and safety of the product.
