Aluminium Folding (Bi-Fold) Doors
Multi-panel doors that fold flush to fully open wide spans, suited to patios and courtyards.
Selective Systems installs TOSTEM's folding door range for openings that want to disappear entirely when open. Panels stack flush against the frame across 4 to 16-panel configurations, sealed with the same rubber gaskets and TEXGUARD finish used across the range — built for patios, courtyards, and any span that wants to open all the way.
Engineered to a Japanese standard.

Learn MoreCommon questions, answered.
How many panels can a folding door have?
Configurations run from 4-panel up to 16-panel, so the system scales from a modest patio opening to a full wall-width span.
What colour should I choose for a folding door?
It depends on the room — lighter tones like white work well in kitchens for brightness, while earthy browns and blacks suit balconies, patios, and living rooms for a more grounded look.
How long do aluminium folding doors last?
Considerably longer than timber alternatives — the corrosion-resistant aluminium frame and TEXGUARD coating are built to handle years of daily folding without warping or fading.
