To ensure adequate insulation in extreme winter temperatures, we have upgraded the hangar door system:
1. A small personnel access door has been added to the sliding hangar door.
2: Both sides feature 0.6mm thick color-coated steel panels. The perimeter utilizes a welded structure of 1.5mm thick post-galvanized steel cold-formed profiles, with polyurethane foam filling the core. This design provides cold resistance, thermal insulation, and impact resistance. The foam has a free density of 55 kg/m³ and high strength.
3: Embedded bolt holes at the top and bottom allow direct connection to upper and lower wheels. This reduces the number of connecting structures, simplifies installation steps, and lowers installation difficulty.
