The cold storage insulated sectional door is a commonly used logistics access door in industrial buildings, especially in buildings with temperature requirements. It has the characteristics of insulation, wind resistance, anti-theft, sealing, safety, and intelligent control. The door panel is composed of multiple layers of panels, with a segmented cold bridge design and filled with imported Huntsman high-density polyurethane material (100% fluorine free). Adopting corrosion-resistant hardware accessories with a dynamic balancing system, the rollers on both sides of the door run up and down along the guide rail as a whole, improving the efficiency and safety of entering and exiting the site. Typical application industries: cold chain, pharmaceuticals, food, and building entrances in cold regions.
