Electric Roller Garage Doors Harpenden

COMPACT & SECURE ELECTRIC ROLLER DOORS

SDM Doors are suppliers and installers of the highest quality electric roller garage doors Harpenden has available. A roller garage door (sometimes known as a roller shutter door) is the ideal solution when driveway space is limited as the door rises vertically, or when you want to maximise height clearance in a smaller garage.

The Trojon roller door merges all the advantages and convenience of a powered operated rolling shutter with the aesthetics required for a truly outstanding garage door.

This exceptional, yet pleasantly priced insulated roller garage door has been specifically designed to improve on many of the virtues of both sectional overhead doors and traditional steel roller shutters and we have installed many of these in Harpenden and the surrounding areas. We are notjust a garage door company, we also supply and install front doors and bifold doors.

INDUSTRY LEADING AUTOMATION

Customers in Harpenden can take advantage of top-tier automation technology from trusted brands such as Somfy and NRG, along with an extensive selection of colours and woodgrain finishes to suit any aesthetic. Unlike many alternatives, our doors come with a full shutterbox as standard, not as a costly add-on. Additional features include a safety edge sensor that reverses the door if an obstruction is detected, a manual override for power outages, and the enhanced protection of the ‘Selve’ high-security locking system.

Each door is crafted using 77mm insulated laths, complemented by durable aluminium guide rails, end plates, and a robust shutterbox, ensuring long-term performance and energy efficiency.

All Trojon products are built to meet the latest European health and safety standards and are engineered for reliability. For added peace of mind, they include safety brakes—similar to a seatbelt mechanism—which instantly engage to prevent the curtain from dropping rapidly in the unlikely event of motor failure.
