What are the necessary factors for safety doors and windows

The safety of doors and windows is a social question. No matter how the performance and appearance of doors and windows change, safety can not be abandoned in any way. In recent years, the frequent accidents of doors and windows remind us to pay more attention to the safety of doors and windows. Let's study the necessary factors of safety doors and windows together.

1. Safety doors and windows - Profiles

The aluminium profiles, thickness, strength and oxide film used in high-quality aluminium alloy doors and windows should conform to the relevant national standards. The wall thickness should be over 1.2 mm, the tensile strength should reach 157 Newtons per square meter, the yield strength should reach 108 Newtons per square millimeter, and the oxide film thickness should reach 10 microns.

2. Safety doors and windows - fine processing

Good aluminium alloy doors and windows, fine processing, exquisite installation, good sealing performance, easy switch. Good aluminium alloy doors and windows, blindly select series and specifications of aluminium profiles, rough manufacturing, sawing instead of milling, not installed according to requirements, poor sealing performance, unsound switches, not only leakage of wind and rain and glass cracking, but also encounter strong wind and external forces, easy to push and pull parts or glass blow down or touch. Falling, damaging people, greatly reducing the degree of security.

3. Safety doors and windows - Safety Guarantee

In general, the cost of high-quality aluminium alloy doors and windows is about 30% higher than that of low-quality aluminium alloy doors and windows because of their high production cost. Some aluminium alloy doors and windows with wall thickness of only 0.6-0.8 mm are made of aluminium profiles. The tensile strength and yield strength of these doors and windows are much lower than those stipulated by relevant national standards and are unsafe to use. In addition, at present, there are many individual households processing aluminum alloy doors and windows. They do not understand the structural characteristics and performance of aluminum alloy doors and windows. In order to reduce the cost of jerry-building and reduce material consumption, it is generally unsuitable to adopt the second-best products, which have greater hidden dangers. Good choice of regular aluminium alloy doors and windows manufacturer's products.
