Seppes RSD-02 High-end Sliding Garage Door

We apply cutting-edge technology from industrial sliding doors to garage doors, offering high-end, durable garage sliding doors of European quality. The garage door panels are made with the same high-quality insulation and sturdiness materials a industrial sliding doors, resulting in a more aesthetically pleasing and sophisticated look.

Thermal insulation and energy saving

The door panel is made of 0.45mm thick color-coated steel sheet. The edges of the front and back steel sheets are not in direct contact after forming, effectively avoiding the cold bridge effect and preventing the door panel from freezing, thus enhancing the thermal insulation and energy-saving effect. The internal filling uses high-density polyurethane foam material with excellent thermal insulation performance, with a foam density of 43kg/m³, which is the highest density standard in the domestic garage door market. The surface is color-coated.

European standard certified, safe and sturdy

Featuring a safe design and rigorous testing, this product incorporates multiple safety features, including a torsion spring anti-breakage device, built-in wire rope, optional wire rope anti-breakage device, and bottom edge protection, effectively enhancing operator safety. All safety devices are certified to European standards and have inspection reports from the French CSTP laboratory.

Special process, excellent sealing

The polyurethane polymer filling provides excellent thermal insulation. Sealing strips between door panels, on the sides, bottom, and top effectively prevent air and rainwater leakage, while the non-contact design of the door panels effectively prevents temperature transfer between the inside and outside, resulting in low energy consumption and low carbon footprint.

Durable and easy to maintain

High-strength galvanized hardware connections, galvanized torsion springs, and torsion spring shaft stress treatment ensure high strength, reliability, and durability. A specially designed embedded steel plate under the hinge mounting position reinforces the connection between the hinge and the door panel. Galvanized roller brackets and wear-resistant nylon rollers provide long-lasting durability and easy maintenance.

Multiple options, diverse enhancements

Up to 11 different lifting methods are available to suit various occasions. Different types of windows can be added to the door panel to meet aesthetic and lighting needs. Optional motor drive is available to improve efficiency. (Prices vary depending on the lifting method.)

Garage sliding door panel technical parameters

• The door panel is 40mm thick, made of double-layer 0.45mm thick color-coated steel sheet. It is produced by Xilang Company's fully automatic color-coated steel coil production line. The color-coated steel coils are produced in-house and use paint from AkzoNobel, a Fortune 500 company in the Netherlands, to ensure the color vibrancy and durability of the door panel.
• The middle layer is filled with high-density polyurethane, with a foaming density of 43 kg/m³
• Thermal conductivity: 0.38 W/m°C
• Sound insulation: 24 dB
• Wind pressure resistance: Level 3 (En13241-1 European standard) (equivalent to resisting level 11 winds according to national standards)
• Water tightness: 30 Pa
• Safety features: Torsion spring balancing device with a cycle life of 25,000 cycles (higher options available); torsion spring anti-breakage device; optional wire rope anti-breakage device.
• Sealing: Sealing between door panels, on both sides of the door, at the top and bottom reduces convection and saves energy.
• Tracks and pulleys: 2mm thick galvanized track, 2mm or 2.5mm thick galvanized roller brackets, wear-resistant nylon rollers.
• Hardware components: Hinges and pulley brackets are made of 2.5mm thick base material with galvanized surface treatment to ensure product durability. The torsion spring base material is Grade A 72B spring steel. All finished torsion springs are tested for torque and torsional force by a CNC torsion spring testing machine, and the testing standard is European standard (EN13241-1).
• Temperature range: -40°C to +40°C
