Industrial Sectional Cold Room Door with Insulated Panel Design
The Industrial Sectional Door is designed for industrial buildings, warehouses, and large access openings where insulation, safety, and durability are required. The door panel adopts a 0.5mm color steel surface sheet with 43kg/m³ high-density PU foam core , providing excellent thermal insulation and structural strength.
The anti-cold-bridge design reduces heat transfer between internal and external surfaces, preventing freezing issues caused by cold bridges. Combined with sealing strips around the panel, it improves airtightness and weather resistance.
