Doors and windows are a house facade, the choice of wear is very important, the quality of doors and windows is determined by a series of complete quality assurance system, the production of doors and windows must pay attention to every production link of the system engineering, in particular, to fundamentally change the contempt for hardware accessories. The bacteria on the brass used in the Tianjin copper door were wiped out in seven hours or less, and if it was on a newly polished brass surface.
Good hardware accessories and good profile combination together, is to the door and window company to spend great efforts in system engineering design and production, and with all relevant parties, especially hardware accessories coordination and cooperation, can have. There are many times, we often hear people complain that doors and windows are so inflexible, just blame hardware accessories. However, other problems, such as the bar, the quality of profile, the accuracy of the notch (such as the size of the notch should be the size of the surface treatment), the processing accuracy of the corners, etc. Then, the door and window hardware accessories should have what kind of function? In addition to meeting the physical properties of doors and windows, mechanical properties, but also to meet the following conditions: First, easy to operate, single point control, by changing the position of the handle and to achieve a variety of opening functions of many life details need to have great wisdom. Many people like to use nice stainless steel door handles because it looks clean and bright and more reassuring, but that's not the case. Research by U.S. scientists shows that stainless steel doorhandles can easily breed pathogenic bacteria that attach to them, including E. coli, streptococcus, Gran's positive and negative bacteria.
