Commercial sectional doors
Commercial sectional doors are designed to deliver reliable performance, thermal efficiency, and space optimization for a wide range of industrial and commercial applications. Constructed from insulated steel panels and supported by precision track and spring systems, these doors open vertically and rest beneath the ceiling, maximizing usable space while ensuring smooth and balanced operation.
Vertical Stacking Sectional Doors
Vertical folding doors are an ideal solution for applications where full clear height is required, such as areas with lifting platforms or where structural constraints must be optimized. Their minimal installation depth makes them especially suitable for buildings with skylights, glass roofs, or façade systems, ensuring that natural light and visibility remain unobstructed at all times.
The door leaf is constructed from aluminum sectional panels, typically divided into 4 or 6 horizontal sections, which are interconnected using specially designed hinges to ensure stable and efficient operation.
Insulated Sectional Overhead Door
Insulated sectional overhead doors are designed to provide enhanced thermal efficiency, structural strength, and smooth vertical operation. Constructed from double-skinned steel panels with an insulated core, these doors help maintain internal temperatures while ensuring durability and reliable performance.
At Alpha Door Systems, our insulated sectional doors are suitable for industrial, commercial, and residential applications, offering effective sealing, reduced energy loss, and compatibility with advanced automation systems.
Insulated Bi- Folding Doors
The door features an ergonomic design that makes it highly suitable for industrial environments, requiring a minimum headroom of only 160 mm. Engineered for long-term performance, it offers Class 4 wind load resistance (EN 12424), ensuring the building remains secure and protected under all weather conditions.
Designed for quick and straightforward installation, the bi-folding door incorporates several functional features, including an embossed steel surface finish, a clear opening without an internal bottom rail, and a full 90-degree opening.
Optional features include a wicket door (with or without threshold), vision panels, and motorized operation, allowing the system to be customized to specific project requirements.
