Suspended gates are a modern and functional solution for covering large openings. The gate leaf slides along the upper rail on roller carriages, providing free space on the ground and making it ideal for hangars, warehouses, and industrial facilities.How does it work?The door leaf, often made of heat-insulating sandwich panels, is suspended by roller carriages from a sturdy steel rail fixed above the opening. Inside the rail are our high-quality roller carriages, which are attached directly to the door leaf and ensure safe, smooth movement of the door to the side without any contact with the ground.Opening coverage optionsDoor leaf width up to 6 mDoor leaf height up to 6 mFor openings of any widthAdvantages of overhead doors:Simple design: no springs, cables, or counterweights — just a guide beam and rollers.Reliability and durability: minimum wear parts, roller bearings ensure movement.Use of building structures as supports: no separate foundation required.Thickened thermal insulation: possibility of installing a door leaf with thick sandwich panels.Ideal for industrial facilities: hangars, warehouses, car washes, service stations.Disadvantages of overhead doors:Restrictions on the height and dimensions of the openingNeed for a strong upper beam/supportThe guide beam takes up space at the topInstallation recommendations:- Use kits with bearing rollers and a guide made of galvanized or stainless steel.- The beam must be level and rigidly fixed.- Provide free space along the movement of the door leaf.- Install catchers and travel limiters.Conclusion: Roll Grand overhead doors are a reliable, durable, and easy-to-use solution for industrial premises and hangars. The absence of springs and complex mechanisms ensures low operating costs and trouble-free operation for many years.
Panel gstes are large overhead doors with sandwich panels and omega profiles, manufactured from our components for maximum reliability.Sandwich panels (steel – polyurethane – steel) are ideal for filling the door leaf. Mineral wool is recommended for fire protection measures.Thanks to rigid polyurethane foam, the panels have high rigidity and excellent thermal insulation with a thickness of only 40 mm, and options with a thickness of 60–200 mm with polyurethane foam or mineral wool are also available.More than 10 basic colors according to the RAL catalogTextures: narrow corrugation (rib), wide corrugation (mid rib), micro rib (microrib), macro rib (macrorib)Embossing: woodgrain, stucco, smooth panel (slick)

Roll Grand LLC offers a unique solution for situations where it is necessary to maximize the width of the opening, but there is not enough space for standard sliding doors.Telescopic sliding gates designsThanks to the telescopic sliding door system, it is possible to create gates that allow you to:● Increase the width of the opening to the required size.● Make effective use of space even in cases where it is not possible to roll back standard leaves.● Implement any architectural or technical tasks, even the most ambitious ones.Advantages of telescopic structures:Compactness: The ideal solution for limited installation conditions.Functionality: The telescopic mechanism allows several gate sections to work smoothly, ensuring easy opening and closing.Versatility: Can be adapted to openings of any size and shape.Reliability: The use of high-quality fittings ensures long-term operation of the structures.
