Frequently Asked Questions — Aluminium Folding Doors Gauteng
- How much does an aluminium folding door cost in Gauteng?
- Aluminium folding doors start from R8,500 for a 3-panel door at Trideniel Aluminium & Glass. The final price depends on the number of panels, door size, glass type and colour specification. All prices include supply, manufacture and installation. Call 078 246 4898 or email sales@trideniel.co.za for a detailed quote.
- What panel configurations are available?
- We manufacture and install 3, 5, 7 and 9-panel aluminium folding doors in both top-hung and bottom-roller systems. Custom sizes manufactured to order for any opening width.
- How long does aluminium folding door installation take?
- Most installations are completed in one day. Larger multi-panel or custom configurations may require two days. Turnaround from order to installation is typically 2-3 weeks depending on specification and glass availability.
- What is the difference between top-hung and bottom-roller folding doors?
- A top-hung system suspends the panels from a track above, leaving the floor completely clear — ideal for patio areas where you don't want a bottom track. A bottom-roller system uses rollers on a bottom track and is more robust for heavier panels. We manufacture both systems.
- Do you manufacture custom size aluminium folding doors?
- Yes. We manufacture aluminium folding doors to your exact specifications from our in-house Gauteng factory. Non-standard opening sizes, heights and configurations are all accommodated.
- What is the warranty on aluminium folding doors?
