Our premium sectional garage doors are available with optional vertical tension spring system (vertical tension spring) or sturdy torsion springs.
Compared to our sectional garage doors with 20 mm insulation, our high-quality premium sectional garage doors with 45 mm insulation (up to 3000 x 2750 mm (WxH))* can be supplied with torsion springs with maintenance-free spring fracture safety device that is tested to EN 12604 for a modest surcharge.
All larger versions are standard equipped with our torsion springs, thus ensuring that the garage door is held firmly and can be pushed up, even if a spring breaks.
*For models with Woodgrain finish. The size restriction for models with smooth surfaces is max. 3000 x 2500 mm.
