Bi-Folding Doors
Our signature doors bring a new dimension of modern, industrial-style design and functionality to your home or workspace. Black Steel's bi-fold external doors are built with slimline frames that allow an amazing level of light into the room, while being strong and secure enough to open up an entire exterior wall, merging your interior living space with the outside.
Why choose steel?
All of our frames are crafted from steel, which is up to three times stronger than aluminium alternatives, giving you doors that are less likely to warp under weight, force or heat. This strength also means we can offer slimmer frames and improved sightlines, maximising light and space without compromising security. Our frames also come powder-coated as standard, to keep your steel pristine.
Our external partitions have some of the slimmest profiles in the industry, refusing to compromise on either strength or elegance.
Make it yours
Bi-fold doors are incredibly versitile, fitting in to your design vision. We offer these frames in a wide range of colours and finishes, so your doors will compliment whatever space you put them in. Download our style examples below to get some ideas to start you off.
Thermally broken
Our external doors and windows let in a stunning amount of light from the outside world, but their thermally broken double glazing means that the temperature inside stays just as you want it.
Thermal breaking is a way of insulating your home from the conditions outside. We incorporate a layer of non-thermally conductive material to separate the internal and external facing parts of the frame, keeping them thermally distinct. So whether it's freezing or sweltering outside, your room will stay the temperature you want it.
Our partitions have achieved a Uw value of xxxx, guaranteeing you an unparalled level of insulation.
