Sealant strip: It is widely used in doors and windows, whether it is the contact part of the door and window fan and the frame, or the contact part of the glass and the fan material. The sealing strip has the functions of shock absorption, elimination, sealing, sound insulation and dust prevention. Therefore, the use of sealing strips is indispensable.

Hinge (sliding support): divided into flat open window sliding support, hanging window sliding support, and flat sliding window sliding support. The first two are similar in style, the opening angle is different from the force, and the flat sliding window is more special and rare. There is not much to introduce here. The sliding bracket is usually made of stainless steel 304, which is strict and even requires 316 material. Very few will have 201 material. As for copper, iron, aluminum alloy and the like, there will be no. When purchasing the sliding support, you can pay attention to the type, size, notch, and thickness of the sliding piece and the load bearing.

Hinge: This should be more we see. It is mostly used on the casement windows, as well as on the casement windows of the old houses. Nowadays, the high-rise outer casement window requires a sliding support.
