How to distinguish between the true and false aluminum windows and doors

Answer:

See the profile of a good structure of the broken bridge aluminum doors and windows profile geometric angle of precision, the profile will not bend twist, angle correct. And the thickness of the surface, such as your custom model of the 60 models of broken aluminum doors and windows, 60 refers to the thickness of 6 cm, and this 6 cm for the full broken bridge aluminum material, wear a small proportion of less; Of the broken aluminum doors and windows, will use the virtual support 60 profiles, with a strip to hold up the thickness of the aluminum material is relatively small.
See the surface quality of the profile of the quality of the profile can be seen from the surface of the broken aluminum profile, good broken bridge aluminum surface glossy texture, surface spray color processing will also be natural, looking at the feeling of smooth; The surface is rough, no luster, it seems feeling unnatural, with a period of time, the poor broken bridge aluminum doors and windows will appear discoloration or discoloration, color is not full.
Look at the insulation of the insulation section of the insulation and domestic and domestic insulation strips are mostly plastic PVC material, imported insulation is polyamide, that is, nylon insulation. Good quality of the broken aluminum doors and windows, the use of imported insulation, and its high temperature and low temperature resistance better, low thermal conductivity, thermal insulation can achieve the effect of environmental protection and energy saving, energy savings of 20% - 30 %.
