The superfast and space-saving Spiral-door.
SDG sets itself ambitious targets in the areas of insulation, noise and pricing.
Our research and development department has succeeded in developing an unprecedentedly fast sectional door that also offers exceptional insulation performance: the SDG Helix. Specially designed rollers keep noise to a minimum. This patented system also contributes to the sleek design of the SDG Helix.
The Helix Spiral Door is a revolutionary innovation and thanks to the spiral system and chain drive does not required extended backroom. To minimize wear and tear the Spiral action of the door means the panels do not touch, roll or fold upon them-selves. The Helix offers a solution in a room where the ceiling construction does not allow track hangers for a regular sectional door.
Because of the intelligent drive-system without counterbalance, the Helix Spiral door does hardly need any service up to 200,000 cycles.
The Helix, Spiral-Door opens 6 x faster than similar sectional doors and is therefore extremely suitable in an environment where you have intensive logistic movements. This door opens fast and depending on the door size up to 1.1 M per second and real savings on the energy cost can be achieved.
The door leaf has a thickness of 40mm and a U-value of 1.5 W/m2K (ISO panels/door leaf 5000 mm x 5000 mm). Additionally where requested we can provide high quality full width ALU vision sections.
