We construct energy efficient industrial building!
Rigid polyurethane insulated sandwich panels are manufactured with standard formula, standard
temperature, standard pressure.Sandwich panels that is made of metal plate (aluminum plate,
steel plate, stainless steel plate) has been widely used to build industrial plant.
