For the anti-corrosion treatment of plastic steel profiles, in addition to considering the assembly gap of various plastic steel profiles to be assembled, it is also important that the sealing strip is uniform and firm. The interface gap should not be greater than 1mm, which fully reflects the sealing performance of the plastic steel window. Plastic steel doors are usually used as inner doors of buildings, and the requirements for sealing are not so high. Various gap values are stipulated in national standards, but for customers, the smaller the gap value at the connection of various profiles, the tighter the fit and the more sophisticated the assembly process. This reflects the assembly level and the accuracy of the assembly tools.
The high starting point of plastic steel profile materials introduced advanced European equipment and technology to seize the commanding heights of the domestic plastic window industry, and successively carried out the capacity expansion of the sixth phase of the project. Plastic steel profiles have the advantages of light weight, high quality and low price, and can be used instead of steel, wood and other products. They are mainly used in plastic steel doors and windows. Moreover, the development potential is huge and the market prospect is optimistic. Plastic steel profiles have better sealing properties than traditional wooden doors and windows, and their strength is greatly increased, which can meet the requirements of building materials. This will also be a new trend in the development of building materials in my country.
