Side Roll-Up Door

Side roll-up doors are suitable for box trucks, refrigerated trucks, and dry cargo trucks. This door offers greater convenience than swing doors, requiring only vertical pulling to open or close. Constructed from aluminum alloy and composite materials, it features PU or PET insulation foam internally. Its excellent sealing performance makes it ideal for urban delivery and short-haul logistics, enhancing distribution efficiency. We offer both manual and electric drive options.
