Why Aluminium Patio Doors?

Before diving into supplier selection, it’s worth highlighting why aluminium is such a popular material for patio doors. Aluminium frames are strong yet lightweight, making them ideal for large glass panels that allow maximum natural light. Unlike wood or uPVC, aluminium is resistant to warping, rusting, and corrosion, ensuring longevity with minimal maintenance. It also supports slimline profiles for a modern, unobtrusive look, while still offering excellent insulation with thermal breaks and advanced glazing options.

Key Qualities to Look for in a Trade Supplier

  1. Product Quality and Certifications
    Look for suppliers who offer high-quality aluminium doors that meet industry standards and certifications, such as PAS 24 for security or Document L compliance for thermal efficiency in the UK. The best suppliers partner with reputable systems companies (like AluK, Smart Systems, or Reynaers) known for their engineered performance.
  2. Customization Options
    Every project is unique. A good trade supplier should offer a wide range of configurations, finishes (like powder coating in RAL colours), glazing options, and threshold styles to meet various design and installation needs. Bifold, sliding, and lift-and-slide options should be available.
  3. Lead Times and Delivery
    Time is money in construction. Choose a supplier known for reliable lead times and prompt delivery. Some suppliers offer fast-track manufacturing options or even stock a range of ready-to-go configurations for urgent jobs.
  4. Trade Pricing and Support
    Competitive trade pricing is essential, but it shouldn’t come at the expense of service. Look for suppliers that offer transparent pricing, volume discounts, and dedicated trade account support. Many also provide CAD drawings, installation guides, and technical assistance, which can streamline your project planning.
  5. Warranty and Aftercare
    A supplier’s warranty is a sign of confidence in their product. Ensure they offer a solid warranty (often 10–20 years) on frames, finishes, and hardware. Additionally, responsive aftersales support is crucial in the event of defects or issues.
  6. Sustainability Practices
    With growing demand for sustainable construction, choosing a supplier that uses recycled aluminium or follows environmentally responsible manufacturing practices can add value to your offerings and help meet green building certifications.
