Door & Gate Systems

High-Performance Sectional Door and Industrial Gate Systems

DoorHan sectional door systems represent the international benchmark in modern building envelope engineering, delivering industry-leading thermal insulation, structural rigidity, and operational security for commercial, logistics, and heavy industrial facilities. Engineered with high-density polyurethane sandwich panels (40 mm) and corrosion-resistant hardware, every system complies with strict EN 13241-1 and ISO 9001:2015 quality standards. Available in custom dimensions with diverse lift track configurations to optimize clearance in any architectural layout.

Engineered to withstand intensive operating cycles and extreme climate conditions, DoorHan sectional door systems prevent thermal bridging and significantly lower facility heating and cooling overhead.

Key Technical Specifications & Engineering Standards:

• Thermal Performance: Superior thermal insulation with heat transfer resistance up to 1.13 m²·°C/W and continuous all-round EPDM perimeter rubber weather sealing.
• Mechanical Endurance: Heavy-duty torsion spring mechanisms engineered for 25,000 to 100,000 continuous operating cycles with galvanized surface treatment.
• Certified Safety Systems: Built-in spring break protection devices, cable break safety catchers, optical safety edge sensors, and full compliance with European standard EN 13241-1.
• Wind Load Rigidity: Structural rigidity tested and certified up to Class 5 wind resistance (EN 12424) under demanding environmental exposure.
• Custom Architectural Options: Integrated pass doors (wicket doors) with ultra-low trip-free thresholds, double acrylic scratch-resistant glazing, and direct-drive automation.

Quality Assurance & Engineering Compliance:

All DoorHan sectional door systems are engineered and tested in accordance with European standard EN 13241-1 and ISO 9001:2015 quality management protocols. Every production batch is certified for Class 5 wind resistance (EN 12424), airtight perimeter sealing, and mechanical torsion spring fatigue endurance. We provide architects, structural engineers, and facility planners with comprehensive CAD drawings, BIM families, structural calculation sheets, and complete wiring schematics to guarantee seamless integration into modern logistics and industrial facility blueprints.

Manufactured across automated continuous production lines, DoorHan sectional systems guarantee exceptional structural durability, minimal maintenance overhead, and turnkey installation readiness across global distribution terminals, automotive centers, and industrial manufacturing plants.
