Material characteristics of broken bridge insulation aluminum
01. Bridge-cutoff aluminum alloy doors and windows is a relatively high-grade aluminum alloy doors and windows. It is the fifth generation of new thermal insulation and energy-saving doors and windows after wooden windows, iron window, plastic steel doors and windows and ordinary colored aluminum alloy doors and windows. Its surface can be painted into various colors.
02. The composition structure of the broken bridge color aluminum alloy doors and windows is combined with wooden window environmental protection, iron window and copper window solid security, plastic steel doors and windows heat preservation and energy saving. Its structure is more complex than ordinary aluminum doors and windows, and its cost is higher. Ordinary colored aluminum does not have heat insulation strips, and heat preservation not available does not save energy. It is only sprayed on the surface.
03. The wall thickness of profile section of bridge-cutoff aluminum alloy doors and windows 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 firm safety of the doors and windows. The wall thickness of ordinary color aluminum doors and windows should generally be below 1.4mm.
04. The color aluminum doors and windows of the Broken Bridge use a special angle code of more than 3mm to set the angle, and the angle glue should be injected into the corner to seal. However, ordinary doors and windows are only connected by pull rivet or screws, and their firmness and safety are poor, but the cost is low. And assembled color
broken bridge aluminum doors and windows there will be no problem for adults to stand up and walk. The technical requirements of assembling complete sets of equipment are far different from those assembled by manual on-site operation. Special broken bridge aluminum profile and ordinary aluminum profile are not of the same grade and cannot be compared.
How to judge the advantages and disadvantages of broken bridge aluminum profiles?
Profile wall thickness:
generally, for home decoration products, most door and window factories choose products with high output rate, that is, products with relatively thin wall thickness to reduce the cost, and 1.3 thick 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.
Heat insulation strip:
PA66 nylon must be used for the most critical part of the Broken Bridge aluminum profile, which is stipulated by the national standard. However, many manufacturers in the decoration market use cheap PVC plastic insulation strips at present, this will seriously affect the service life and safety of the product.
