Six-Panel Bifold Door
Six narrow full-height leaves close across the patio opening. Folding hinges link the panels so the whole group folds into a compact stack, and the leaf divisions read through the closed door as a regular rhythm.
The standard frame is 6063-T5 aluminum in a 75-series system with a 1.8 mm profile wall, joined around the glass with aluminum corner cleats and stainless steel fasteners. A wood-grain surface is available as a finish on that aluminum frame.
The operating package includes 304 stainless steel load-bearing rollers, folding hinges, a multipoint lock, recessed pulls and EPDM gaskets. Track, roller and hinge selection follow the complete glazed leaf weight.
The standard package pairs the 75-series aluminum frame and 1.8 mm profile wall with 5 mm tempered glass, a 12 mm cavity and 5 mm tempered glass, specified together as one matched frame-and-glass system.
The budget construction uses a 55-series non-thermal frame, a 1.4 mm profile wall and 6 mm single tempered glass. With a single pane, a non-thermal profile and its own hardware, it is a different system from the standard package and is quoted as one.
The reinforced alternative uses an 85-series thermal-break frame with a 2.0–2.2 mm profile wall and 6 mm glass, a 16 mm cavity and 6 mm Low-E glass, which calls for heavier sections and running hardware. Frame color, sheen and hinge and pull finishes are coordinated with the chosen system.

The folded stack occupies space beside the opening. Inward folding uses indoor floor area; outward folding uses the patio side. Furniture, planters and circulation routes stay clear of both the moving panels and the parked stack. The operating plan identifies which side receives that movement.
Overall frame width includes the perimeter and panel stack. The usable passage is the space remaining after the doors are parked, with handles and stops also affecting travel.
A low sill and a weather-focused sill are different interface choices. Interior and exterior finished levels determine how the threshold meets floor finishes and exterior drainage. A flush-looking detail still needs the appropriate supporting weatherproofing and fixing arrangement.
The quotation follows all six leaves, perimeter members and their glazing areas, with panel width, height and parking arrangement setting hardware and fabrication. A different panel count is quoted as a new operating layout.
The selected standard package keeps its 75-series frame, 1.8 mm profile wall and 5/12/5 tempered insulating glass together. The 55-series single-pane and reinforced 85-series Low-E constructions change both frame and glazing. The quote names the complete package and matching operating hardware.
Rollers, folding hinges, locks, recessed pulls and gaskets form the operating set. Sill choice and drainage details affect additional components. A separate everyday swing access leaf is not part of this selected six-panel package unless it is actually designed and scheduled.
The supplied door assembly is separated from the supporting opening, floor preparation, flashing and perimeter sealing. Packing protects the long frame members and glazed leaves. Freight, unloading and local installation are identified for the actual destination and site access. Tell us the rooms and quantities and we will put this on one quote with everything else you are ordering, and show you what fits in a container.
The selected package is a six-panel folding assembly. A separate everyday swing access leaf changes panel divisions, hinge and locking arrangements, and the usable clear passage. That access function is a distinct operating layout.
Bifold leaves are connected by hinges and fold into a stack. A conventional sliding door keeps its leaves parallel and parks one behind another. The folding stack and movement envelope use space beside the opening.
The folding direction is selected for the opening. Inward movement occupies interior floor area; outward movement occupies the patio side. Furniture, planters and walkways need clearance from both the moving leaves and parked stack.
The standard choice is a 75-series aluminum frame with a 1.8 mm profile wall and 5/12/5 mm tempered insulating glass. The 55-series single-pane and reinforced 85-series Low-E systems change both the frame and glazing. Their parts are not treated as interchangeable options inside one unchanging door assembly.
The parked panels and perimeter take part of the width, so usable clear passage is recorded as well as overall frame width. Handle projections and operating stops also affect the final passage.
The bifold is available with a low-profile sill for an easy step-through or a raised weather sill for exposed facades. We match the sill, drainage and seals to your site exposure, and where your project needs a performance report, such as AS 2047 or EN 14351, we confirm which tested system it covers.
