Construction&Energy Supply

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.

ADVANTAGE

Polyurethane insulation material has excellent thermal insulation performance, perfect bonding with a variety of surface materials. Modern plant manufacture process ensures color steel compound sandwich panel being produced with a standardised and large-scale production

PROCESS

Continuous production Mainly.

TECHNOLOGY

The formula has high tolerance that adapt to different production processes
