Product Description
                                                                                                                                                                                                                                                                                        High-quality imported hardware
Adopting the original Germany hardware brand, all-metal aluminium material, surface anti-corrosion treatment,exquisite craftsmanship, it's secure and anti-pry.
High-precision profile
6063-T5 high-precision aluminum profile and taking into account the strength, toughness, and corrosion resistance, it has excellent performance.
EPDM co-extrusion strip
The use of the EPDM automotive-grade sealing strip can ensure the sealing effect while it has good weather resistance and aging
resistance so that it has a longer service life.
                                                                                                                                        Insulating glass filled with argon
The thermal conductivity of argon is lower than that of dry air, which effectively reduces the temperature difference between the exterior and interior, and improves the thermal insulation effect. In addition, the hollow glass has a built-in molecular sieve to absorb water vapor in the glass to prevent fogging and mold.
Corner angle bonding with injection method
The corners of window frames and sashes adopt the mechanically crimped and sealed and corner angle bonding with injection method,so that it can not only guarantee the sealing of the door and window corners but also has stability. The mullion adopts the pin
bolt glue injection process, which has a more stable structure and superior performance, and it has reached the leading position at the industry level.
Much wider thermal barrier
Thermal barrier width: 64mm, which has better performance.
