Sectional Overhead Doors

sectional overhead doors

Our sectional overhead doors seamlessly blend top-tier security, exceptional thermal insulation, and aesthetic versatility, making them a perfect complement to any architectural design, from the sleek and modern to the classic and traditional, meaning these roller shutters can be used in a range of applications in industrial buildings or commercial premises. Crafted with precision, these doors feature panels united by a tongue and groove system that incorporates a thermal break, ensuring maximum energy efficiency. The panels are expertly interconnected with hinges and glide effortlessly on wheels within a track system, transitioning from a vertical to a horizontal overhead position when opened, embodying the epitome of smooth operation.

While our standard range presents a refined selection of colours, we proudly offer customisation with any colour from the extensive RAL or BS spectrum, allowing for a tailor-made appearance that perfectly suits your style. Opt for the convenience of electric operation for effortless access or the simplicity of manual operation, including push-up/pull-down or chain hoist mechanisms, to meet your specific needs.

Each panel is 40mm insulated composite, featuring a 0.5mm hot-dipped galvanised steel on both sides, encasing a rigid polyurethane core. This construction not only provides robust thermal insulation but also a sound reduction of 25dB, ensuring a quieter, more comfortable environment. Galvanised steel end caps and hinged brackets with adjustable roller carriers further enhance the door’s durability and performance.

Embrace the blend of functionality, efficiency, and style with our sectional doors, available in a wide range of colours and equipped with insulated panels, vision panels, and the choice between electric and manual operations. Choose our sectional overhead doors for an uncompromising addition to your industrial doors portfolio, ensuring optimal thermal insulation and a distinguished appearance.
