Premium Features & Technology
40mm Insulated Panels
Temperature Control
0.5mm galvanized steel sandwich panels with high-density PU foam. Thermal insulation ≤0.033 W/m²·K. Ideal for temperature-controlled environments and cold storage.
Heavy-Duty Track System
Multiple Lift Options
Standard lift, high lift, vertical lift, or follow-roof configurations. 2.0-3.0mm galvanized steel tracks. Designed for heavy panels and frequent operation.
Weather Sealing
Complete Protection
EPDM rubber seals on all sides. Bottom seal adapts to uneven floors. Keeps out dust, rain, and pests. Maintains internal environment.
Safety Features
EN 13241 Compliant
Anti-pinch panel joints. Spring brake device. Finger protection on panel edges. Optional photobeam sensors and warning lights.
Lift Type Options
Standard Lift
Door follows ceiling, then curves up and runs horizontally under roof. Most common and cost-effective option. Requires headroom ~350-500mm.
High Lift
Door rises vertically above opening before running horizontally. Useful when ceiling space is limited close to opening but available further back.
Vertical Lift
Door rises straight up and stops. Requires headroom equal to door height. Ideal for buildings with high ceilings and no horizontal space.
Follow Roof
Door tracks follow the roof pitch. For buildings with sloped roofs where standard tracks won’t fit. Custom engineering required.
Customisation Options
Personalise your industrial sectional door with window layouts, finishes, and convenient access options.
Window Options
Add windows to bring light into the space and complement the building design.
- Rectangular or arched windows
- Clear, tinted or frosted acrylic
- Single row or multiple rows
Special Color Options
Select colours and panel patterns that match your facade.
- Standard RAL colors
Door-in-Door
Pedestrian door inside the sectional door for quick access without full opening.
- Convenient daily entry/exit
- Reduces wear on main door
- Ideal for workshops
Matching Personnel Door
A separate pedestrian access door installed next to the main door, manufactured with the same panel design, color, and finish for a seamless appearance.
- Maintains a clean and consistent façade design
- Convenient daily access without opening the main door
- Ideal for workshops, warehouses, and industrial buildings
Where to Use Industrial Sectional Doors

Frequently Asked Questions
What’s the maximum size available?
With the SOMMER GIGAsedo operator, we can install doors up to W 12000mm × H 8000mm. For larger openings, we can provide custom solutions or recommend alternative door types like high-speed fold-up doors. Contact us with your specific requirements.
Why SOMMER motors for industrial doors?
SOMMER is a German manufacturer with over 40 years of experience. The GIGAsedo is specifically designed for industrial applications — heavy doors, frequent cycles, and demanding environments. It’s the same brand we use for residential garage doors and automatic gates, ensuring consistent quality across all our products.
Can the door include a pedestrian pass door?
Yes. We can include a door-in-door — a pedestrian door built into one of the panels. This allows people to pass through without opening the entire door, saving time and energy.
How do I know which lift type I need?
It depends on your ceiling structure and available space. Standard lift is most common and cost-effective. Our team will survey your building and recommend the best lift configuration based on your structural conditions.
What happens during a power failure?
Every installation includes a manual chain hoist. During power outages, you can operate the door manually by pulling the chain. The SOMMER motor also has an integrated mechanical brake that holds the door securely in any position.
