Professionals of the Quality Supervision and Inspection Institute (QA/QC) believed that the advantages and disadvantages of heat-insulating plastic steel windows and doors are mainly considered in the three major aspects of profiles, hardware accessories and processing technology. First, we must first understand the profile of plastic steel doors and windows, good profiles should be a reasonable design of multi-cavity, wall thickness, formula containing anti-aging, anti-ultraviolet additives, from the appearance point of view should be smooth surface, color blue and white. Second, look at the quality of the assembly of doors and windows, mainly to see whether the appearance of smooth and non-destructive, whether the welding angle is neat, whether the hardware is aligned, there is no lining steel and so on. For steel doors and windows, good lining steel should be galvanized A3 steel, wall thickness of at least 1.2mm, so as to ensure the insulation effect of plastic windows. From the processing technology, the pros and cons of the processing technology determine the pros and cons of the apparent quality of the doors and windows, the accuracy of the processing dimensions, the level of the welding strength, and the rationality of the use of hardware accessories all affect the quality and performance of the doors and windows, plus the quality of the process. The same cannot be ignored. Third, we must check whether the manufacturer's production licenses are issued by the construction company. Don't try to be cheap and cheap. The quality of the insulation and plastic windows used in the street workshops cannot be guaranteed. Experts advise consumers to sell regular products. Qualified goods.
