Sandwich Panel

　　Color steel sandwich panel
　　Color steel sandwich panel consists of two layers of pre painted galvanized corrugated color steel and inside insulation layer. There are total four types, polystyrene (EPS) sandwich panel, fiber glass (glass wool) sandwich panel, rock wool (mineral wool) sandwich panel and polyurethane (PU) sandwich panel.


　　Polystyrene (EPS) sandwich panel
