PPGI Sandwich Panel
A sandwich panel is made with a core of thermal insulating material and covered with two pieces of metal sheets. Our sandwich panels use GI, GL, PPGI, PPGL steel sheets. Generally, the types of sandwich panels are grouped by core materials, for example, EPS (expanded polystyrene), PIR, RW, XPS, PU, and PF. The main differences between them lie in their fire resistance, sound-heat-insulating performance, etc.
