1, sealing strip
Because the combination of the door and the door panel is a hard bump between the plates, the instantaneous noise of closing the door is as high as 120 decibels, which seriously affects the physical and mental health. The high-strength sealing strip is used, which does not react with the paint, ensuring the smoothness of the contact paint surface. And it also has shock absorption, noise reduction, sealing, sound insulation, moisture resistance and so on.
2, sliding support
A device for supporting the opening and closing and positioning of the casement window sash. Consumers should use stainless steel materials when purchasing. The surface should not have scratches, sharp edges, burrs and other defects. When the sliding support is opened and closed, there is a slight resistance.
Take the weight of each sliding door and window and move it horizontally. When purchasing, consumers should pay attention to the material of the pulley frame and whether the pulley adopts needle roller bearing or ball bearing. For the pulley used for sliding door, the heavy-duty door pulley should be used, and the pulley of the sliding window should not be used instead.
Used in casement windows. The main function is to press the sash against the window frame when the sash is closed to achieve the sealing function. Consumers should pay attention to observe that the surface is flat, burr-free, the weight of the handcuffs, and the surface of the coating is uniform.
