ã€China Aluminum Network】 In real life, we know little about the expertise and terminology of aluminum doors and windows of thermal insulation bridge profiles, leading to the majority of customers how to choose insulated aluminum and how to identify the advantages and disadvantages. How to do.
First look at the material, good aluminum alloy doors and windows for aluminum, thickness, strength and oxide film, etc., should meet the requirements, the wall thickness should be 1.2 mm or more, at least to the yield strength of 108 Newtons per square millimeter, 157 newtons per square millimeter The tensile strength, oxide film thickness of 10 microns. For those who do not meet the above criteria, it is inferior aluminum alloy door and window profiles, please carefully choose the decoration customer.
Secondly, the fine degree and professional technical ability of the door and window manufacturers on the thermal insulation bridge profile processing are the key points that customers should consider. A good profile can be equipped with a good manufacturer, a professional production and installation worker, and it can be “a good horse with a good saddleâ€. ! The technical installation is excellent, in order to make its sealing performance and switch freely. On the contrary, the technicians blindly selected the aluminum profile series and specifications, processed rough construction, even replaced the milling process with saw cutting, and the installation and construction personnel did not install as required. This resulted in poor sealing performance of the doors and windows, and the switch was not smooth and could not effectively Blocking wind and rain, serious may also cause the glass to burst. Under normal circumstances, good aluminum alloy doors and windows due to high production costs, the price must be about 30% higher than inferior aluminum alloy doors and windows. For some aluminum alloy screen doors and windows produced using aluminum profiles with a thickness of only 0.6-0.8 mm, the tensile strength and yield strength are far lower than the relevant national standards, and the use is also very unsafe. As the saying goes, "a penny and a piece of goods," when customers choose profiles, do not just care for a little cheap.
