Industrial Roll-Up Door Installation & Repair With over 55 years of combined industry experience, United Door & Gate Multi-Services / Manufacturing is one of Florida’s most trusted providers of industrial roll-up door installation, repair, and maintenance. Our legacy dates back to our time operating as Rolling Door Parts, giving us deep technical knowledge few contractors can match. Industrial roll-up doors are mission-critical systems used in warehouses, factories, logistics hubs, government facilities, shipping centers, and manufacturing plants. These doors operate under high frequency and heavy load, making proper installation and maintenance essential. We install heavy-duty industrial roll-up doors, insulated systems, hurricane-rated doors, high-cycle industrial doors, full-width and oversized systems, and counter shutters and security roll-up doors. Our installations include reinforced guides, precision drum alignment, high-cycle springs, correctly rated operators, and professional-grade hardware to ensure long-term durability and smooth operation. Our repair services address jammed or stuck roll-up doors, bent or damaged slats, motor and gearbox failures, chain hoist systems, guide and track issues, spring tension problems, curtain separation, and impact damage. We understand that downtime costs money, so our industrial technicians respond quickly to restore your doors to full operation. We install and service high-cycle operator systems from LiftMaster, Micanan, Manaras, Genie Commercial, Doorking, Linear, Crocodile, and more. Each operator is calibrated to the exact weight and height of your roll-up door to maximize performance and safety. Preventative maintenance is critical for industrial roll-up doors because of their heavy use. Our maintenance program includes tension adjustments, operator testing, lubrication, safety system calibration, hardware tightening, and wear-and-tear review. Routine maintenance reduces downtime, extends equipment life, and ensures safe, reliable operation.
