Key Features to Consider When Choosing a Sectional door
Durable and robust, providing all-weather protection
Durable and robust sectional overhead doors, typically constructed from double-layered high-strength steel panels filled with high-density polyurethane foam, provide reliable access control in demanding outdoor and industrial environments. Designed to withstand strong winds, extreme temperature fluctuations, and moisture corrosion, these doors have become the preferred standard for modern logistics centers, large manufacturing plants, and warehousing facilities. Their sturdy structural design and excellent insulation properties translate into years of trouble-free operation, giving managers confidence in their long-term performance and safety.
Safety and Protection Systems
- Torsion spring break devices are needed to be installed with any industrial sectional door in a logistics or manufacturing center owing to strict mechanical safety code compliance.
- Closing hazards are common in busy docks, so safety technology such as bottom safety airbags (safety edges) are used widely to ensure protection while vehicles and personnel are passing through.
- Installing wire rope break protection protects the users and heavy door panels from getting damaged and minimizes potential loss due to suspension failure, preserving service reliability for future operations.
Customization Options for Specific Needs
Because no two building openings are identical, manufacturers offer a range of customizable configurations—allowing facility managers to specify panel thickness, track lift types, and window arrangements that best suit each application. Options such as pedestrian pass doors (wicket doors), vision panels, and automated radar sensors streamline workflow efficiency while maintaining indoor temperature stability. This adaptability means managing traffic at a busy logistics dock or sealing a temperature-controlled warehouse, the sectional door can meet operational goals without compromise.
Choose The Optimal Installation Method For Your Sectional Doors
SEPPES provides flexible track configurations to maximize your facility's overhead space and operational efficiency.
Special Configurations and Applications of Sectional Doors
Integrated Wicket Door
Convenient Personnel Access Designed for high-traffic facilities, our integrated wicket doors (pass doors) allow for easy personnel entry and exit without needing to open the entire sectional door. This feature significantly reduces energy loss, maintains indoor temperature, and extends the lifespan of the main drive system by reducing unnecessary cycles.
Reinforced Wind-Resistant Panels
Maximum Structural Integrity For ultra-wide openings or areas prone to extreme weather, we offer panels with external "back rib" reinforcements. These thickened steel stiffeners provide superior structural rigidity, allowing the door to withstand high wind loads while preventing panel deflection or bowing over long-term use.
Explosion-Proof Drive System
Safety for Hazardous Environments Engineered specifically for industries such as chemical processing, oil & gas, or pharmaceutical labs. This system utilizes ATEX/IECEx certified motors and spark-free control boxes. It ensures stable, automated operation while meeting the highest safety standards for volatile or combustible atmospheres.
Bespoke Finishes & Textures
Tailored Architectural Aesthetics Beyond standard industrial gray, we provide a full spectrum of RAL color customization and surface textures. Choose from woodgrain, stucco, or micro-ribbed finishes with high-performance powder coating to match your corporate branding or the specific architectural requirements of your facility.
Key Components of Industrial Sectional Overhead Doors
High-Insulation Panels
Constructed with double-sided galvanized steel skins and high-density CFC-free Polyurethane (PU) foam. Featuring a thickness of 40mm/50mm, these panels provide exceptional thermal insulation, wind resistance, and structural integrity.
Heavy-Duty Track System
Built from 2.0mm+ hot-dipped galvanized steel. The optimized track geometry combined with high-quality nylon rollers ensures silent, smooth operation and long-term durability even in high-frequency usage environments.
Precision Balance System
Our engineers use specialized software to calculate the exact torsion spring requirements for every door. This ensures a perfect counterbalance, making even large doors easy to operate manually and reducing the load on the motor.
Intelligent Drive System
Features advanced soft-start and soft-stop technology to minimize mechanical wear and extend the door's lifespan. The intelligent control box ensures stable performance even in high-frequency environments

Frequently Asked Questions
Q: What type of track lift fits my building if I have limited headroom?
A: We offer customizable track configurations to suit different building structures. Besides the Standard Lift, we provide High Lift (for higher ceilings) and Vertical Lift (for high-bay warehouses) to maximize your vertical space utilization. Just send us your opening dimensions and ceiling height, and we will design the optimal solution.
Q: How does the sectional door perform in extreme weather conditions?
A: Our doors are constructed with double-layer galvanized steel sheets filled with high-density polyurethane foam. This “sandwich” design, combined with all-around EPDM sealing strips, provides excellent thermal insulation and wind resistance, effectively keeping indoor temperatures stable and reducing energy costs.
Q: What safety features are included to prevent accidents?
A: Safety is our top priority. Every SEPPES sectional door comes standard with a Torsion Spring Break Device and a Wire Rope Break Device to prevent the door from falling in case of suspension failure. Additionally, a Bottom Safety Airbag (Safety Edge) automatically rebounds the door if it encounters an obstacle while closing.
Q: Can I integrate a pass door for personnel without opening the main door?
A: Yes, we can install a Pedestrian Wicket Door within the main sectional door panels. This allows people to enter and exit quickly without operating the large door, which extends the motor’s lifespan and minimizes heat loss.
Q: How do I operate the door if there is a power outage?
A: Don’t worry. All our motorized sectional doors are equipped with a Manual Chain Hoist. In the event of a power failure or emergency, you can easily switch to manual mode and open or close the door using the hand chain.
