Sandwich panel
Sandwich panel is composed of outside color steel sheet and heat insulation core material. It can be categorized into four series according to different insulation core material, as below:
- Fiber Glass Sanwich Panel
- Rock Wool Sandwich Panel
- Polyurethane(PU)Sandwich Panel
- Polystyrene(EPS)Sandwich Panel
