1 Weld the square pipe into a supporting underframe, and keep it on a horizontal plane with the same area as the gusset plate.

2 Fix the triangular keel on the square pipe rack and set a certain distance. For example, the standard size of three-dimensional gusset plate in Guangfeng is 300mm*300mm, so the distance between keels should be 300mm.

3 according to the pre-arranged pattern, the three-dimensional gusset plate is buckled on the triangular keel one by one.

4 wrapping (depending on the specific implementation), different materials can be used for wrapping.

5 After the project is finished, you can wipe the gusset plate with a clean wet cloth.
