We manufacture custom-made aluminium bifold doors using the Alunet BF73 Bifold Door System. Our doors have a modern style and come in large sash sizes up to 1200mm wide and 3000mm tall, with slim sightlines of 120mm to maximize natural light and scenic views

We offer a 10-year factory power coating warranty and 12-month hardware warranty to ensure our customers are satisfied with our product.


Our bifold doors can be customized with one to eight panels, providing a perfect fit and appearance for your home. With each sash having the capability to be up to 1200mm wide and 3000mm high, more light and glass can be incorporated.

The cost of our aluminium bi-folding doors is determined by the number of panels required. Our Bifold Door Designer tool generates instant quotations to give you an idea of the pricing.


We take pride in producing robust, dependable and long-lasting products. Doors made of aluminium are popular as they offer strength and security, while being resistant to rust and corrosion.

Our bifold door hardware boasts an attractive and secure design. As standard, our doors feature a multi-point locking system with double hook locks and six locking points, exceeding the typical three-point system. For maximum security, our bifolds can be upgraded with an Ultion three-star barrel lock to meet the rigorous PAS 24 accreditation standards.

Our bifold door handles have a sleek, curved design and come in seven finishes, including black, white, grey, chrome, stainless steel, and rose gold. The variety of options allows you to choose the best fit for your property and personal style.


Our high performance bifolds have a U-value as low as 1.2 W/m2K, which satisfies building regulation requirements. They are designed to enhance energy efficiency by retaining warm air and preventing cold air from seeping in.


We have 3 standard powder coated colours of Anthracite grey (RAL 7016), Black (RAL 9005) & White (RAL 9016). In addition to our standard colours we also have a wide range of colours and offer any RAL colour to suit your needs. If you’re looking for a bespoke colour please contact our friendly team.


As standard we supply all bifold doors with low-e double glazing, if you require any other glass including laminated, Ultra Low-e, triple glazing or any other specific glass please get in touch. We can also provide our bifold doors un-glazed.


Bifold doors offer a great way to connect your indoor and outdoor spaces, but they can compromise privacy. Integral blinds are a practical solution, installed between glass panes to reduce glare and provide privacy. They are also known as integrated blinds or blinds in glass, and can easily be added to your bifold door order.

Investing in your home is a significant decision, as it involves expenses and the expectation of good value for your money. Adding an exquisite aluminium folding door can assure you of receiving maximum value from your investment, thanks to the various benefits it offers to your property. While bifold doors are available in a range of materials and styles, you may wonder why you should choose an aluminium bifold door over others. To provide a better understanding, we have listed the key advantages of aluminium bifold doors for you to consider, making it a great addition to any home.


Customizing aluminium frames to fit your desired size, colour, and finish is effortless. In the past, brushed aluminium was the only option, limiting the appearance of aluminium. However, now they can be manufactured in a variety of colours, including sleek black or grey finishes, offering a contemporary and stylish appeal.


One of the advantages of aluminium is its durability and resistance to deterioration, ensuring a long-lasting lifespan. After powder-coating, it does not discolor, peel or rust, reducing the need for costly repairs or replacements. Opting for aluminium bifold doors means investing in a high-quality, low-maintenance material that will provide a modern and elegant appearance to your home for years to come. If you prefer to avoid purchasing doors that require constant upkeep and maintenance, aluminium is the perfect material choice for you.


Compared to timber or UPVC, aluminium frames are typically narrower. This allows for larger glass panels to be installed, increasing the amount of natural light in your home and providing a broader view of your garden. This is particularly advantageous when used for larger bifold door configurations.


The durability of aluminium is unparalleled, allowing for larger glass panes to be installed without compromising the strength and safety of the doors. This means they can be placed in areas like conservatories, covering entire walls if desired. Aluminium bifold doors provide excellent protection, and the fixings and attachment points for handles, locks, and hinges offer additional security.


Our aluminium bifold doors offer numerous optional extras such as integrated blinds, astrical bars, various frame colors, and glass options. With this level of flexibility, you can customize your doors to perfectly suit your home's requirements, ensuring you get exactly what you want.


By installing aluminium bifold doors, you are making a valuable investment that can increase the resale value of your home in the future. The durability of aluminium ensures that it will last for many years to come. Interior bifold doors create more space and open up your home, while exterior doors provide a unique, modern, and eye-catching appearance, attracting more potential buyers.

As experienced aluminium bifold door manufacturers and suppliers, we understand the importance of providing high-quality doors at an affordable price. With our online design feature, you can create your desired bifold doors to get an idea of the cost and appearance. If you have any questions or concerns, our team is available to assist you and bring your vision to life.


Wonderful service from start to finish. I came across Prime Aluminium online, after receiving a few quotes from others I found these to be the best price I could find. Delivered within the time scale promised and really pleased with the quality of the doors. Send them a picture of your door after it’s been fitted and you will be entered in to a draw for a voucher. Fingers crossed. Thank you.

Very happy with our doors, we got a few quotes from some other companies which was in excess of £10,000 for 4 bi-folds – Prime Aluminium saved us over £3000. Anyone thinking about fitting yourself just make sure there is 2 of you as the panels are about 50kg each. Will recommend in the future to anyone looking for new bifold doors.
