EPS 3D sandwich wiremesh wall panels are lightweight, prefabricated building materials made of an expanded polystyrene (EPS) insulation core, enclosed between two layers of galvanized steel wire mesh connected by diagonal steel trusses. Once installed, the panels are coated with cement plaster or shotcrete to create strong, insulated, and durable walls, floors, or roofs. They are widely used in modern construction due to their high strength-to-weight ratio, thermal insulation, quick installation, and resistance to earthquakes and fire.
