Our GMT building formwork is an excellent replacement for Plywood due to their excellent mechanical properties at low weight, outstanding impact strength even at low temperatures, and broad resistance to moisture/humidity, outdoor weathering, and common chemicals. Our products can be sawed, stapled, nailed, or glued like plywood and will not splinter,which are used widely in various construction projects and recyclable
