As we all know, hardware accessories are the heart of doors and windows. The full performance of all the performances of doors and windows, such as wind pressure resistance, air tightness, water tightness, heat preservation and sound insulation, are closely related to hardware accessories.
The painful thing in the world is that the rainy days of the winter return to the south of the door and the hinges of the door are rusted. Every time the door is closed, it must endure the harsh torture.
The more painful thing in the world is that it shivers in the quilt and the bolt is broken. The north wind blew, the doors and windows squeaked, and the people were noisy.
The most painful thing in the world is that you have heated in the north, but found the sliding support card, the window is not tight, and the heating is running.
The most painful thing in the world is that in the south you have shaken like a sieve, and found that the handle is broken, the door is closed, and you are cold and cold.
Hardware lock points and lock seats are distributed around the entire door and window. When the door and window are locked, the lock point and the lock seat are firmly fastened together, and cooperate with the hinge or the sliding support to jointly generate a strong sealing pressing force, so that the sealing strip is deformed by force, thereby providing sufficient sealing performance for the door and window. Forming the fan and the frame together can greatly improve the performance of the door and window.
The normal opening and closing of doors and windows is inseparable from the tacit cooperation of each hardware accessory. Therefore, the door and window hardware is the "heart" of the doors and windows. Inferior doors and windows hardware is easy to rust, not wear-resistant, rough craftsmanship, inferior raw materials, and flashy. It was originally a simple helper, but in turn caused many unnecessary troubles to life.

Door and window hardware accessories are selected by the manufacturers to import high-quality manufacturers such as HOPPE, KDOK, SIEGENIA and ROTO FRANK. To ensure the quality of the product hardware and the longer service life, the product is more high-end luxury. Uniform use of European standard standards makes replacement more convenient and convenient, and there is no worries after sale.
There are too many imitation manufacturers in the market to judge the authenticity of the door and window hardware:
First, it is to see the surface of the metal is smooth and not easy to produce scratches.
Second, it is to open the sound of mechanical transmission structure brought by imported hardware. After tens of thousands of opening tests, the mature production process makes the product durable, while meeting the needs of various door and window opening forms and providing more hardware styles.
Doors and windows are lightweight components, and their energy consumption accounts for more than half of the building energy consumption, which is the top priority of building energy conservation. When designing, we must fully consider the energy-saving problems of doors and windows, namely insulation and heat insulation. If there are no multi-point lock hardware accessories, the doors and windows do a good job, and its insulation and heat insulation performance will not be ideal.
