Process characteristics and properties

1. the frame of the box body is made of ten percent off profiles, and the high-quality and special three links are welded together into a whole. The structure is solid and reliable, and the appearance is graceful.

2. the lower edge of the door plank is about 25mm away from the ground, and the rectangular frame fixed on the door panel is provided with a circular hole every 25mm, so as to not only enhance the strength of the door panel. It can also be used to install electrical wiring harness, electrical appliances and other components.

3. the top cover, side plate, back slope and bottom plate are all screwdriver fasteners fixed, easy to assemble and disassemble, and the installation work inside the cabinet is more convenient.
