Expandable Frame

The structure of expandable frame is flexible. The width and height of the expandable frame can be adjusted according to the thickness of the wall, making the installation and operation simple and fast. If your wall surface is uneven, or the reserved installation gap is too large or too small, you don’t have to worry, because the expandable frame can perfectly solve this problem. Expandable frame ensures that the installation is not only simple, but also easily meets the quality requirements.


Expandable frame uses the knock down packing, which means the hinge jamb, the strike jamb and the head are packaged separately. The advantage is saving space and loading more goods in one container, thus you will save a lot of transportation costs.

Expandable frame can be treated by powder coating or laminated PVC, giving the frame rich colors and textures. Thanks to various styles and knock down packing, expandable frame is really popular in European and American countries.
