Hardware accessories is responsible for the frame of door window and door tightly coupled components, metal price is not high, not its existence, Windows will only become a death, will lose the meaning of the doors and Windows. We from the performance of the doors and Windows and function to analyze the role of hardware accessories for doors and Windows:
Doors and Windows physical performance indicators are: the wind resistance, air tightness, water tightness and thermal insulation, thermal insulation, sound insulation, resistance to pressure. Metal material first for doors and Windows can wind pressure resistance, determines the success or failure of doors and Windows; Also, air tightness, water tightness, insulation, thermal insulation, sound insulation sex are related to hardware accessories in the doors and Windows sealed.
Hardware accessories and lock lock distribution around the doors and Windows. After the door lock, lock, lock button firmly together, cooperate with hinge (hinges) or sliding support, for with a powerful force of sealing pressure, make the sealing strip elastic deformation, thus providing enough for doors and Windows sealed performance, make fan, box form which can greatly improve the performance of Windows and doors. Similarly, Windows and doors fold mechanical performance index (opening and closing force, repeatedly opening and closing), such as opening and closing demands is also inseparable from the hardware store.
Doors and Windows is a lightweight component, its use accounted for more than half of the building energy consumption, energy consumption is the key of the building energy conservation, doors and Windows should be fully considered in the design of the energy saving problem, namely, insulating heat preservation sex and stays. If there is no more lock hardware fittings, doors and Windows do again good, the insulating heat preservation, stays. Similarly, anti-theft doors, Windows performance is also the most concern of the owner. This aspect, anti-theft performance of hardware accessories, especially in daily hardware development but also play an important role in intelligent anti-theft doors and Windows of the component.
Door window has a variety of shape and structure, and the various function of window type, all depends on the configuration of hardware accessories. Imagine, there is no hardware fittings, smooth window open the suspension of how to implement the function of both flat open and pour inside? Push-pull folding doors and Windows and how to implement both push and pull and folding functions? Push and pull, activities within shutter, etc., which is not on the role of hardware fittings reached its unique specific functions? To say the metal parts is the "heart" doors and Windows accessories.
