FAQ
Q: What is the estimated 3 metre aluminium bifold exterior doors cost?
A: Pricing is dictated by your chosen glazing and panel configuration. A standard 3-meter, 3-panel double-glazed system offers an excellent baseline cost-to-value ratio. For an exact figure tailored to your site (including custom RAL colors or triple glazing), submit your rough opening sizes to our team for a fast, itemized quote.
Q: Can I order custom size exterior aluminium bifold doors, and what is the lead time?
A: Yes. Every project is different, which is why we manufacture custom size exterior aluminium bifold doors to millimeter precision. For standard black or grey profiles, our manufacturing lead time is reliably 3-4 weeks. Specialized configurations may take 5-6 weeks.
Q: Do you offer supply only aluminium exterior bifold doors for the trade?
A: Absolutely. We work closely with builders, architects, and independent installers. Our supply only aluminium exterior bifold doors are securely crated and delivered directly to your site, complete with all necessary hardware and glazing ready for installation.
Q: Do you provide instructions on how to install aluminium exterior bifold doors?
A: Yes. Every delivery includes comprehensive technical manuals, toe-and-heeling guides, and track alignment specifications. However, due to the critical nature of leveling the tracks and balancing the glass weight, we strongly recommend installation by a qualified glazing professional.
Q: Are these systems rated as heavy duty commercial grade aluminium bifold doors?
A: Yes. The 1.8mm-2.0mm wall thickness of our extruded aluminium means they do not just look good; they are structurally rigid. They will not warp or sag, making them perfectly suited for both residential builds and high-frequency commercial applications.
Q: What is the warranty, and do you supply replacement tracks for exterior aluminium bifold doors?
A: We back our products with a comprehensive 10-year guarantee covering the aluminium profile, powder coating, and thermal breaks. Because we manufacture the systems, we carry all proprietary spare parts. If your site ever requires replacement tracks for exterior aluminium bifold doors, weather seals, or new roller carriages years down the line, we dispatch them directly from our warehouse.
