Among the various systems of doors and windows, hardware may seem small and unremarkable, but it is actually the "heart" of the doors and windows, influencing their performance, usage experience, and lifespan, and even being closely related to their safety, determining their wind pressure resistance, air tightness, water tightness, heat insulation and sound insulation properties, and other performance indicators. The hardware system of doors and windows includes:
1. Handles: Operate the opening and closing of the doors and windows, ensuring sealing and safety. The materials are diverse, including
aluminum alloy which is lightweight and corrosion-resistant, copper which has a good texture, stainless steel which is durable, and zinc alloy which has a rich shape. The styles include European, American, and Chinese, suitable for different decoration styles.
2. Pulleys: Used for sliding doors and windows, they bear the weight and make the opening and closing smooth and reduce noise. The wheels are made of nylon, POM, and stainless steel, and the bearings are made of stainless steel or copper. Ordinary pulleys are suitable for lightweight doors and windows, while heavy-duty pulleys are used for large doors and windows, and silent pulleys reduce noise.
3. Locking points and locks: Form the locking system, enhancing security and ensuring uniform force on the doors and windows. The materials are mostly stainless steel or zinc alloy. Single-point locks are suitable for simple doors and windows, while multi-point locks are used for high-end doors.
4. Lock straps: Connect the locking points with the lock core or transmission device to achieve the telescopic locking and closing of the locking points. The materials are stainless steel or carbon steel, and are specially treated to be more durable. There are flat and round lock straps, suitable for different locks.
5.
hinges and hinges: Connect the door leaf and the window frame to ensure the flexibility and stability of the rotation. The materials include stainless steel, copper, and aluminum alloy. Hinges include ordinary, spring, and hydraulic types; hinges include ordinary, large door, and bearing hinges, and spring, hydraulic hinges and large door, bearing hinges each have their advantages.
6. Anti-drop ropes: Essential for high-rise buildings, preventing the door leaf from falling. Steel wire ropes have high strength, and nylon ropes have good flexibility, and are available in built-in and external types.
7. Transmission devices: Transmit the action of the handle, achieving synchronized locking and opening of the doors and windows, and enhancing overall performance. The materials are mostly stainless steel and zinc alloy, including translational, sliding, and opening transmission devices, suitable for different doors.
