Sectional overhead doors






Sectional Overhead Doors
Sectional overhead doors are a superior choice for industrial and commercial facilities due to their space-saving design, durability, and enhanced security. Unlike traditional doors, sectional overhead doors consist of multiple horizontal panels connected by precision-engineered joints, allowing them to glide smoothly along tracks and open vertically. This unique operation optimises space, making commercial sectional overhead doors ideal for environments with limited clearance or restricted working areas.
Sectional overhead doors, designed with tension spring technology and reinforced with robust retaining cables, ensure exceptional security, insulation, and weather resistance. Their high-quality construction and customisable features make them a preferred choice for warehouses, loading docks, workshops, and other commercial settings where reliability and efficiency are paramount.

The benefits of industrial & commercial doors
Safety
Safety is a key priority for any business, and sectional overhead doors are designed with built-in safety mechanisms to prevent accidents. Features like anti-drop safety brakes, tension springs, and obstruction detection sensors help minimise risks and ensure smooth, controlled operation. These features make commercial sectional overhead doors a secure and dependable solution for high-traffic areas.
Customisation
No two commercial buildings are the same, which is why commercial sectional overhead doors come with various customisation options. Including: size and dimensions to fit specific openings, glazing options for enhanced visibility, colour and finish selections to match corporate branding, automation features such as remote control, motion sensors, and access control integration. These options allow businesses to create a solution that enhances both security and aesthetic appeal.
Space saving
Unlike traditional swing doors that require extra clearance, sectional overhead doors open vertically and align parallel to the ceiling, maximising usable space. This design is particularly beneficial for warehouses, logistics centres, and manufacturing plants, where every inch of space matters.
Energy efficency
One of the biggest advantages of sectional overhead doors is their thermal efficiency. Insulated models reduce heat loss, minimise energy costs, and improve climate control within commercial facilities. This is especially beneficial for cold storage facilities, food processing plants, and temperature-sensitive environments.
