3d wpc wall panel design

The biggest advantage of this design is that 3d wpc wall panels are constrained by each other, and one 3d wpc wall panel will remain stable due to the constraints of two adjacent 3d wpc wall panels.
The traditional screw fixing method, once encountering thermal expansion and contraction, the 3d wpc wall panel will warp, and the panel surface will directly arch up, which is very troublesome.
