Spring door series

●Excellent heat-insulating property allows the system to generate a prominent energy saving effect. Different types of insulating aluminum profile and insulating glass unit are adopted to achieve reasonable heat transfer coefficient K value in order to meet the requirement of energy saving.
●Multi-level sealing system，structural drainage is achieved based on pressure balancing principle, the water-tight property is reliable and stable.
●Constant strength insulating aluminum profile with Thermal Bar, and advanced corrugated recombination craft is applied to make sure the profile possess sufficient tensile strength and shear strength.
●Any desired color and texture of the aluminium profile can be achieved through four surface treatment ways (anodizing, electrophoretic coating, static blasting painting, PVDF coating), wood grain spray coating can also be applied. Different colors can be applied on the inner and outer surface of the doors and windows.
●The entire doors and windows are designed for a long performance life, all the aluminium profile, hardware fitting and sealing gasket are endowed with ageing-resistant and corrosion-resistant property.
●Mature and complete doors and windows processing technic, products are processed at high precision CNC, standardized and large-scale volume production guarantee a stable and reliable quality.
●The major erection work are conducted indoors simply and efficiently, technical maturity guarantee a stable quality and a convenient operation for maintaining and glass changing.
●Smooth and durable unlocking and locking, strict inspection and test have been conducted for every single product and movement, and fatigue test times surpasses 100 thousand.
●Recyclable and green building materials enable the products to be eco-friendly, which complys with the strategy of sustainable development.
