Cold Room Lifting Door
The thickness of our cold room lifting door panel is 0.5mm color steel, and the edge sides of color steel won’t directly contact each other, which can effectively prevent the door panel frozen by the result of the cold bridge.
Our cold room lifting doors use 43kg/m³ high-density PU foam between color steel.
Sealing strips around the door panel effectively prevent air and rain penetration.
Our cold room lifting door has a safety device with European standard certifications and French CSTP test reports. The safety device includes:
- NFMG spring
- Inner steel wire rope
- Steel wire anti-fracture device
- Bottom protection
