Trade Supply Aluminium Patio Doors – desirable products, you and your customers will love

“Patio doors” doesn’t mean just one type anymore. From sliding systems to French or steel-look doors, the category now includes multiple formats to suit different properties. Here’s how our range supports your residential and commercial projects:

We supply multiple solutions that meet the needs of different homes and projects:

• Sliding Doors: GS15 and GS20, two of the UK’s slimmest sliding doors and with flush stacking, seamless tracks and look minimalist and elegant.

• Our GS25 designed for the largest door openings and even automation

• The affordable and trade friendly GS47 that’s easy to sell and install.

• Bifold Doors: GB49, the contemporary, slimline and ultra-reliable bifold.

• French Doors and Double Doors: Using the bifold profiles, you get slimmer doors capable of larger sizes without the need for toplights or side panels, like regular residential doors. Industrial style options are also available.

• Steel-look and Industrial Style Patio Doors: Glazed with transoms and glazing bars for a heritage style

Whether it’s a minimal sliding system or a heritage-style French door, they all count as aluminium patio doors. We give you the flexibility to specify the right style for every property whilst also being in the advantageous position to provide bifold, single and French doors all with matching sightlines and even right down to matching hardware.

Durability and Longevity

Patio doors are best done in aluminium. Slimmer sightlines, more glass, less frame, flush tracks where needed—and long-term durability. Our entire patio door range is fabricated from premium-grade aluminium with Qualicoat-approved powder coatings. This resist fading, chalking, and corrosion with minimal maintenance.

Sophisticated thermal breaks work with your chosen glass spec—toughened or laminated, double or triple. We also offer upgrades like solar control and acoustic glazing. Our colour offering includes options not available from standard trade suppliers, with custom finishes available on request.

Our doors also use upgraded components and manufacturing techniques. And we support your own installation guarantee with our own as well, up to ten years, depending on the product.

Energy Efficiency Features

Our re-engineered systems are designed for modern thermal performance. Double and triple glazing options are available, depending on the product.

And unlike other systems there is no confusion over U-Values. We can assist you with technical specifications and help you achieve compliance with current Building Regulations.

The highest quality products – Quality Assured

We can assure you that it is not just the larger businesses with their own paint plants that offer certified quality. So do ours. We know our trade customers want reliability as well as offering your end-user customers peace of mind. That’s with trade supply aluminium patio doors from Glideline, you get:

• Qualicoat Approved powder coated finishes, tested to the latest standards and with just routine cleaning resist fading and corrosion

• Premium-grade aluminium profiles such as 6063 T6 alloy, extruded specifically for architectural applications including windows and doors.

We want to ensure every product we provide for you is realisable, with no call-backs and a reliable, safe, secure and reliable door for your end-user customers, that promise word of mouth recommendations and fantastic reviews.

Customisation Options Available

We manufacture all our trade supply aluminium patio doors to order and to spec. That means you can offer homeowners tailored solutions that suit both function and design:

• Panel Configurations

Two, three or four-panel sliding doors

Open corner or pocket sliding options

Inward or outward-opening French or bifold doors

• Track Options

Flush or low track thresholds are available across our sliding and bifold systems, supporting level interior-exterior transitions without compromising on weather protection.

Need help with configurations or quoting? We’re on hand to support you.

And some suppliers have been extolling the virtue of their “new” flush stacking sliding doors? Well, we’ve been doing these for years already and our existing installers love this feature.

Enhanced Security Features

As with most well-designed and high quality aluminium patio doors for the trade, you expect great security features you can confidently explain to your own customers.
