The plastic-wood composite material is processed into various profiles by extrusion molding. The profiles can be set with the required grooves as a socket column, and can also be made into a solid or hollow board as a wall panel. Simple or temporary housing can take full advantage of its strengths. It can be built into temporary houses for earthquake relief, kiosks, guard boxes, temporary workshops, mobile toilets, beach and swimming pool clothing rooms or tool rooms, and military field activity rooms. Plastic-wood houses often use a plug-in assembly structure, which can be disassembled and assembled repeatedly, so some call them mobile houses, and they can also be built into relatively fixed ones according to needs, such as kiosks, guard boxes, etc. Most of the construction work is completed in the factory, and the on-site installation is very simple and does not require high operating skills. A simple plastic-wood house can be built in less than a day, so it is especially suitable for use in emergency situations, such as war. , disaster relief, etc.
