How to weld and hoist billboards without deformation
⓵Using aluminum-plastic panels to make steel hangings for billboards, how to do it, specific steps
The triangular iron frame must be burned according to the actual size. It must be straight and flat, and welded and fixed according to the actual position. There are two ways to do it. 1. If it will not be exposed to rain, use self-tapping screws to attach a layer of plywood and then use special all-purpose glue to affix the aluminum-plastic panels according to the design. 2. If it is in the open air, there is no need to install plywood. Just divide the aluminum-plastic panels into the designed grids, make pits and edges, and fix them with glass glue. Before applying glass glue, you can put some double-sided tape on it for temporary fixation. The glass glue will pre vent it from falling off.
