Model 011 Industrial Sectional Overhead Door
The Model 011 Industrial Sectional Overhead Door is engineered for warehouses, logistics distribution centers, manufacturing facilities, and commercial buildings requiring robust security, dependable thermal insulation, and versatile architectural configurations.
Manufactured with high-density polyurethane (PU) insulated sandwich panels (available in 42 mm, 50 mm, and 75 mm thicknesses), Model 011 delivers superior thermal performance ( U=1.0 W/(m²⋅K) on steel panels) while maintaining an operational noise level of ≤55 dB(A). Tested to European industrial standards for wind resistance (Class 2/3), water permeability (Class 3), and air tightness (Class 3), this sectional door accommodates clear openings up to 9,000 mm (W) × 9,000 mm (H) and supports customized integration with pedestrian wicket doors, full-vision panoramic panels, and multiple automated actuation devices.
Key Engineering Features
- Multi-Thickness Thermal Insulated Panels
- Available in 42 mm, 50 mm, and 75 mm panel thicknesses with high-density CFC-free polyurethane cores. Achieves a verified thermal transmittance of
- 1.0 W/(m²⋅K) (tested on a 5,000 mm×5,000 mm steel door), significantly lowering facility heating and cooling costs.
- Certified European Standard Environmental Protection
- Delivers Class 3 Water Permeability (EN 12425) and Class 3 Air Permeability (EN 12426) on solid panel configurations. Structural reinforcing profiles ensure Class 3 Wind Load Resistance (EN 12424) for widths <4,250 mm (Class 2 for widths >4,250 mm or configurations with integrated wicket doors).
- Low-Noise Electric Drive with Manual Chain Override
- Driven by high-efficiency industrial gear motors (500W / 650W / 800W options) operating at a quiet sound level of ≤55 dB(A). In the event of a power outage, an integrated heavy-duty manual chain hoist allows manual operation without disengaging the balance system.
- Integrated 900 mm Pedestrian Wicket Door (Optional)
- Features an optional 900 mm wide built-in pass door with a standard 180 mm reinforced threshold, continuous perimeter seals, and heavy-duty structural profiles, allowing personnel access without opening the full sectional door.
- Modular Vision & Full-Panoramic Glazing
- Available with anti-tamper rectangular or oval acrylic windows, or fully glazed anodized aluminum framed sections (single or double acrylic/polycarbonate, clear, frosted, or tinted options) to maximize natural light transmission.
- Wide Ambient Temperature Tolerance
- Engineered to operate reliably across extreme industrial climates from −30°C to +75°C with an IP54 electrical enclosure rating.
