With the development of the door and window industry, people's requirements for the performance of doors and windows have been gradually improved. From the original simple shelter from wind and rain to the present wind and rain, heat preservation and energy saving, sound insulation and waterproof, the performance and quality of broken bridge doors and windows have been further improved.
The national standard of Aluminum Alloy Doors and Windows is GB/T 8478-2020, which gives the corresponding grades for all aspects of product performance and process requirements. However, for coastal areas with more stringent living requirements, can the current national standard meet people's performance requirements for doors and windows?
In terms of climate, the living environment in coastal areas is facing a more severe test than that in inland areas! Typhoon, rainstorm, returning to the south, strong sunshine, etc. are problems that coastal residents often face. Therefore, aluminum alloy windows are facing more challenges, such as high salinity, high temperature, high humidity, strong wind, exposure and other harsh conditions, which bring great challenges to the material, design, manufacture and installation of aluminum alloy windows. Therefore, home doors and windows need higher product requirements in terms of safety, water tightness, air tightness and heat insulation.
Ruiwu doors and windows have been focusing on the research and production of aluminum alloy doors and windows in coastal areas for a long time, and high-quality products have been welcomed and praised by many coastal areas such as Sanya, Zhanjiang, Shenzhen and Xiamen. In order to meet the market demand, Ruiwu Doors and Windows submitted an application to China Construction Association to formulate the group standard of "Broken Bridge Aluminum Alloy Windows for Marine Environment" and got a reply at the first time.
