ROLL GRAND LLC offers many options for sets of components and accessories for the independent manufacture of suspended structures (gates) to block the opening to the workshop, warehouse, hangar and other production facilities.
Our solutions are suitable for:ā construction of hangars,ā agricultural farms,ā storage facilitiesother buildings of any type.Product features:ā Thickness of thermal insulation: from 40 to 200 mm, which allows to adapt structures to any climatic conditions.ā Wide range of fittings: ensures the implementation of any project - from standard passageways to large-scale aircraft hangars.ā Versatility: the products meet a wide range of thermal insulation and operational requirements.
Suspended gates are sliding gates whose leaf is raised by rollers to a rail attached above the opening to be covered. Such a door is a leaf suspended by roller carriages from a rail mounted above the opening. With the help of our hardware, hanging gates can cover an opening of any width, and the leaf of one leaf is up to 6 m wide and up to 6 m high. Suspended gates are a reliable structure consisting of a canvas made of heat-insulating sandwich panels, which moves along a profiled steel rail and is suspended without contact with the ground. Inside the rail are roller carriages that are attached directly to the door leaf and guarantee safe sideways movement of the door.
Advantages of overhead gates:ā Maximum simplicity of designā No springs, cables, counterweights, complex mechanisms - only a guide beam and rollers fixed to the top of the door leaf. āāReliability and durabilityā Almost no elements of active wear. Bearings in the rollers are the only driving element.ā Use of building structures as a supportā The role of the supporting structure is often played by a hangar, shed, metal frame, fence, etc. - no need for a separate foundation.ā Use of thickened insulation materialsāāUnlike sectional doors with springs, a thicker layer of thermal insulation can be installed - convenient in heated industrial premises.ā Ideal for industrial facilitiesā Often used in hangars, warehouses, workshops, car washes, service stations - due to their reliability and ease of maintenance.
Disadvantages of overhead doors:ā Restrictions on the height and dimensions of the openingā The guide beam takes up space from above - cannot be used on openings with low ceilings or in residential garages.ā Need for a strong upper beam/supportThe entire load is on the top of the structure - a rigid and reliable metal support is required. ļæ½ļæ½ļø Useful tips for hanging gates:š§ Choosing a kitBuy kits with bearing rollers and a galvanized or stainless steel guide.Consider the weight of the door leaf and choose a set with a load margin (up to +50% of the door weight).ļæ½ļæ½ļø InstallationThe beam must be perfectly flat and rigidly fixed - deformation due to heat/freezing is possible.Pay attention to the overhang of the door leaf - it will move along the wall or partition, so you need to provide free space.Install catchers/stroke limiters to avoid spontaneous rollback.
š Conclusion: Suspended gates are an ideal solution for industrial premises and hangars, especially if simplicity, reliability and low operating costs are required. The absence of springs and wearing mechanisms makes them convenient for long-term operation.
Panel doors are large hanging doors with sandwich panels and using the omega profile and our components.
Sandwich panels (steel - polyurethane - steel) are ideal for filling the door leaf. For fire protection measures, mineral wool is the best choice. Due to the use of solid polyurethane foam, this type of panel is highly rigid and has excellent thermal insulation with a thickness of only 40 millimetres, but there are options with a thickness of 60 - 200 mm with mineral wool or polyurethane foam. Sandwich panels are available in more than 10 basic paint colours according to the RAL catalogue. There are also many texture options, for example, narrow corrugation (rib), wide corrugation (mid rib), micro strip (microrib), macro strip (macrorib); surface embossing can be woodgrain, stucco or smooth panel (slick).
Roll Grand LLC offers a unique solution for situations where it is necessary to maximise the opening width, but there is not enough space for a standard sash rollback.Telescopic leaf structures With the telescopic leaf system, you can create a door that allows you to:ā Increase the opening width to the required size.ā Efficient use of space even in cases where there is no possibility to roll back standard leaves.ā Realise any architectural or technical tasks, even the most ambitious ones.
