PU Sandwich Panel

high density cold room sandwich polyurethane sheet

Polyurethane foam is been sandwiched between the two outer skins and hence is known as PU sandwich panels. We are engaged in manufacturing reliable PU sandwich panels in variegated specifications.. Those two layers are available i profile with zinc coated, galvanized steel, embossed aluminum, stainless steel or other material sheets.
