High-Speed Mega Door for Large Industrial Openings
OZ HSD MEGA is a large-opening high speed door for exterior factory, warehouse and industrial entrances exposed to wind. Its reinforced PVC curtain folds above the opening using a high-power drive system, making it suitable where a standard roll-up high speed door cannot adequately meet the opening size, structural or wind-load requirements.
- For large exterior and exposed openings
- Door size, structure and drive system engineered for each project
- High wind resistance with reinforced curtain
- Ideal for warehouses, docks and cold storage
How the OZ HSD MEGA Handles Large Openings
Belt Drive System
Efficient Large Door Control
Belt structure enables efficient control of large doors. Ideal for openings larger than 6m × 6m where standard roll-up drums cannot handle the size.
Windproof Structure
30 m/s Wind Resistance
The larger the door, the bigger the wind problem. Support bars provide a strong windproof structure for exposed external walls and dock positions.
Truss Structure Self-supporting design
Compact Stack Design
Engineered with a robust Truss Frame that supports its own weight, allowing installation in open areas without rear walls. This system overcomes site constraints for large openings while ensuring maximum structural stability.
PVC Curtain
0.9mm (1100g/m²) or 1.6mm (1930g/m²) thickness. UV treatment prevents discoloring. Waterproof, anti-bacterial. Temperature: -5°C (0.9mm) or -30°C (1.6mm) to +70°C. Colors: Orange, Yellow, Blue, Grey.
Integrated PMSM Servo & Smart Control
Rare-earth permanent magnet motor with a double encoder system for high torque and energy efficiency. Direct shaft-driven for space-saving. The integrated LCD controller supports 3 modes (Auto/Manual/Jog), self-diagnosis, fault history, and maintenance reminders with auto-adjusting torque.
Aluminum Alloy Frame
2–3mm thick aluminum frame and 2mm cover with anodized silver finish. Does not rust, easy to maintain. Optional SUS304 stainless steel or painted steel available.
Where to Use a Mega Door
This large industrial fabric door is intended for exterior or exposed openings facing wind, weather and heavy logistics traffic. The final size is confirmed from the opening dimensions, wind exposure, building structure, curtain weight and motor duty for each project.
- Warehouse loading docks – high-volume truck loading and unloading
- Cold storage & frozen facilities – external doors where cold loss must be minimised
- Large factory exterior openings – wind-exposed walls and production bays
- Logistics hubs & distribution centres – continuous truck traffic and cross-docking
- Industrial hangar-style openings – where standard high speed doors are too small
Mega Door vs Standard High Speed Door
A Standard model suits typical internal openings and frequent traffic. OZ HSD MEGA uses a folding curtain, reinforcement bars and a project-engineered support structure for much larger or wind-exposed openings. Selection should therefore consider the opening, building position, wind load and traffic pattern rather than width alone.
| Design factor | Standard model | OZ HSD MEGA |
|---|---|---|
| Opening | Typical factory and warehouse openings | Large openings and custom projects |
| Position | Internal or external when specified | External, exposed and wind-facing walls |
| Curtain system | Roll-up drum with wind bars | Fold-up curtain with reinforcement bars and truss structure |
| Engineering | Selected from standard size ranges | Structure, wind load, motor and installation space checked per project |
Information Needed to Engineer a Large Door
- Clear opening width and height, plus available headroom and side room
- Internal or external position, prevailing wind direction and weather exposure
- Daily operating cycles, vehicle type and traffic flow
- Power supply, activation method, safety sensors and PLC integration

Why Choose OZ HSD MEGA for a Large Door
OZ HSD MEGA is intended for large, wind-exposed factory and warehouse openings that require a fast industrial door with a reinforced folding structure.
Handles Large, Windy Openings
Designed specifically for big external doorways and wind-exposed walls that require stronger performance than standard high speed doors.
Protects Goods & Energy
Fast closing reduces dust, rain and hot air infiltration, helping protect products and reduce cold loss at loading bays and cold rooms.

Frequently Asked Questions
When should I choose a Mega Door instead of a Standard high speed door?
Choose OZ HSD MEGA when the opening is large, wind-exposed or used as an exterior industrial entrance. A Standard model is generally more suitable for typical openings or internal traffic zones.
How large can an OZ HSD MEGA door be?
OZ HSD MEGA is engineered per project. The confirmed size depends on the building structure, wind load, curtain weight, installation space and drive system. Our engineers review the site data before confirming a safe size.
Is a Mega Door suitable for cold storage facilities?
It can suit selected external cold-room entrances and loading docks. Temperature, humidity, operating cycles and the dock-shelter arrangement should be reviewed before selecting the curtain and sealing configuration.
How much headroom is required for installation?
Headroom depends on the door height and folding arrangement. Our team reviews the building drawings and confirms the required lintel and side space before installation.
What warranty is provided?
OZ Door products include a 2-year warranty subject to company terms. Inspection and maintenance plans are available for high-cycle industrial use.
