Applications in Large Projects

Hotels and Hospitality Buildings

Banquet hall to terrace openings, poolside cabana fronts and hotel lobby separators for large hospitality projects. Maximum opening for indoor-outdoor integration is a key specification requirement for IGBC-rated hotel buildings. Top-hung systems leave the floor completely unobstructed — no threshold trip hazard in high-footfall circulation zones.

Shopping Malls and Anchor Stores

Anchor store frontages, food court separators and mall atrium enclosures. Large unobstructed openings for high-footfall retail environments. Our top-hung systems allow retail floor plans to extend fully to the opening without interference from bottom-track hardware.

Airports and Transit Buildings

Folding door systems for airport VIP lounges, executive club entrances and terminal building commercial zones requiring flexible space division. Supplied with full structural and thermal documentation for airport authority submission. Systems specified at AAI and private airport terminal projects across India.

Institutional Buildings and Government Projects

Conference room access points, auditorium lobby separators and large hall openings in institutional buildings — IIT campuses, government secretariats, convention centres and public sector offices. NBC 2016 compliant with emergency egress documentation on request.

How wide can an aluminium folding door span?

Individual folding panels run 600–1000mm wide and up to about 2.7m tall, and a single track can carry several panels to span openings of 6m or more. The practical limit is set by panel weight on the top-hung rollers and the threshold detail rather than the aluminium itself — 6063-T5 extrusions handle the structural side comfortably.

What is the difference between aluminium folding and sliding doors?

A folding door stacks its panels concertina-fashion to open almost the entire span, which suits restaurants, balconies, and retail frontages that want a fully clear opening. A sliding door keeps panels in plane and only ever opens half the width, but seals better against weather and dust and costs less. Choose folding for maximum opening, sliding for weather performance and value.

Are aluminium folding doors suitable for Indian weather?

Yes, provided the system is specified with proper weather seals, a drained threshold, and thermally appropriate glazing under ECBC 2017. 6063-T5 aluminium doesn't corrode or warp in heat and monsoon humidity the way timber does, and powder-coated or anodised finishes hold up for 15+ years. The failure point in Indian installations is almost always the threshold drainage detail, not the door.

Frequently Asked Questions

What is the maximum opening size for your aluminium folding door systems?

Our top-hung aluminium folding door systems can span openings up to 6 metres wide in a 6-panel configuration, with individual panel widths up to 1000mm and heights up to 3000mm. Larger spans are possible with structural engineering support — we supply shop drawings for all project submissions.

Is a floor track required for your folding door systems?

No. Our folding door systems use a top-hung tracking mechanism, which means there is no bottom floor rail. This is particularly important for large hospitality and institutional projects where an unobstructed floor surface is required. A flush threshold seal is fitted to maintain weather performance.

Can folding doors be specified with double glazing for thermal performance?

Yes. Our aluminium folding door systems are available with double glazed units (DGU) for ECBC-compliant thermal performance. DGU folding systems are commonly specified for hospitality buildings targeting IGBC Green Hotel certification and institutional buildings with air-conditioning energy performance requirements.

What documentation do you supply for project submissions?

We supply AutoCAD shop drawings, section drawings, wind load calculations to IS 875 Part 3, hardware schedules and finish specifications. For large projects, we can provide structural engineer-stamped calculations for local body and authority submissions.

What finish options are available?

All systems are available in powder coat finish (any RAL colour) or anodised finish (silver, champagne, bronze, black). Minimum order quantities apply for non-standard RAL colours. Anodised finish is recommended for coastal and high-humidity environments.

Folding Door Panel Configurations

Aluminium folding and bifold doors are configured in 2-panel to 5-panel arrangements depending on the opening width and the clearance available for the stacked panels when fully open. A 2-panel bifold on a 1,800mm opening stacks to 900mm — suitable where wall clearance is available. A 4-panel system on a 3,600mm opening stacks to 900mm on each side, leaving the full opening clear — ideal for hotel function rooms, restaurant terraces and large residential entertaining spaces.

Panel fold direction (outward or inward) is determined by the site conditions — outward folding provides a wider clear opening and better visual effect from inside, but requires external clearance for the stacked panels and exposes the hinges to the weather. Inward folding is specified where external clearance is limited and weather exposure of the hardware is a concern.

Hardware, Track and Threshold Design

Top-hung folding door systems carry the panel weight on the overhead track, leaving the floor threshold as a slim flush seal rather than a structural element. This gives a level threshold — important for HAG accessibility compliance and for visual continuity between indoor and outdoor spaces. The top track must be structurally adequate for the panel load: for 5-panel systems with DGU glazing, the total panel weight can exceed 200kg, requiring the track to be supported at centres confirmed by structural calculation. We provide track loading specifications for every folding door order so the building structural engineer can confirm the support framing design.
