I. Product Name

Sectional Overhead Door

II. Product Introduction

The cold storage sectional overhead door (also known as a lifting gate or vertical sliding gate) operates through vertical upward sliding. When opened, the gate body is positioned above the door opening, avoiding occupation of entry/exit space or side clearance. Powered by motors or manually assisted, it ensures smooth operation. This specialized gate design is ideal for large-scale cold storage facilities, logistics cold storage systems, and workshop cold storage environments requiring efficient equipment and cargo handling, balancing high throughput with optimal space utilization.

The door panels feature integrated high-density polyurethane foam, offering exceptional thermal insulation that effectively retains cold and reduces energy consumption. Available in standard thicknesses of 100mm, 150mm, and 200mm, these panels can be flexibly selected according to specific cold storage temperature requirements, making them suitable for various fresh-keeping, refrigeration, and freezing applications.

The panel is available in materials such as 304 stainless steel or color-coated steel plate. The door frame undergoes anti-corrosion and low-temperature treatment, offering resistance to moisture and aging, making it suitable for the low-temperature, humid environment of cold storage facilities while balancing durability and aesthetics. Customization options are available as needed.

The dimensions are customizable, with standard door openings available in 1.5*2.4m,2.0*2.5m, and 3.0*3.0m sizes. Both single and double doors can be customized, accommodating even large door openings to meet the needs of forklifts, heavy machinery, and bulk cargo handling. These doors are suitable for various cold storage construction and assembly applications.

III. Product Features

1. Space-saving and efficient passage: The vertical sliding mechanism opens, with the door stored above the doorway, avoiding occupation of entry/exit channels and side spaces. Ideal for narrow areas, it ensures rapid and smooth operation, significantly enhancing the throughput efficiency for large goods and equipment.

2. Sealed insulation with significant energy savings: The door body fits precisely with the door frame, complemented by low-temperature resistant sealing strips and bottom sealing brushes, ensuring tight closure that effectively prevents cold leakage, stabilizes warehouse temperature, and reduces cold storage operational energy consumption.

3. Robust and durable with excellent wind resistance: Featuring a high-strength profile frame and thickened door panels, combined with premium guides and a transmission system, it offers superior load-bearing capacity and smooth, lag-free operation. Its outstanding wind resistance makes it suitable for outdoor installation scenarios. The hardware components are treated with anti-corrosion and low-temperature protection, ensuring a long service life.

4. Safe and reliable with user-friendly operation: Supports both motor-driven and manual emergency opening mechanisms, equipped with limit switches and anti-fall devices to prevent door detachment or excessive operational damage; optional infrared sensors and light curtain protection are available to avoid injury to personnel or cargo during operation.

5. Flexible customization with broad adaptability: Dimensions, panel materials, and door thickness can be customized to meet specific requirements, suitable for cold storage applications in various industries such as food, pharmaceuticals, cold chain logistics, and industrial sectors. The system supports upgrades to transparent viewing windows and access control integration, fulfilling tailored demands.
