1. Good safety performance: the overall embedded connection of the window frame makes the structure more stable and stronger against wind pressure.
2. Import hinge: strong and constant type, anti-oxidation, can withstand multiple opening and closing, flexible and silent
3. Advanced group corner process: aluminum corner code, deflector, steel sheet, group angle injection extrusion synthesis process
4. Insulating glass molecular sieve: keeping the air in the glass interlayer dry and heat insulation
