Sliding and Bi-folding Doors
Steel Sliding Doors That Redefine Room Flow
CRIT Steel Doors manufactures single, double, and triple leaf sliding systems for properties across Harrow and London. Recessed pocket units vanish into the wall, top-hung panels glide along a discreet overhead rail, and barn-style doors roll on exposed tracks for a more industrial character. Our double sliders feature a threshold-free mechanism that keeps the floor line completely clear. Steel frames, rails, and hardware throughout, with 6mm toughened safety glazing as standard and laminated upgrades on request.

Folding Steel Walls That Blur the Line Between In and Out
Imagine pulling back an entire elevation to merge your living room with the garden. Our bifold system carries two to fourteen solid steel leaves along a heavy-duty track, stacking them neatly to one side in seconds. Magnetic catches or traditional lock-and-handle sets secure the panels when closed. Equally effective as an interior room divider or an exterior terrace enclosure, every bifold is fabricated in steel and glazed with 6mm toughened safety glass, with laminated options available to specification.
The Transformative Power of a Steel Bifold Wall
Replacing a solid rear wall with a folding steel-and-glass system changes the entire personality of a home. Slim sightlines preserve clean views when the panels are shut, and the stacking action opens the full aperture to create one continuous indoor-outdoor space. Daylight reaches further into the floor plan, rooms feel noticeably larger, and the connection to the garden becomes effortless. Behind the visual impact sits genuine substance: thermally efficient profiles, certified security, and a steel structure built to perform for decades. Whether you are upgrading a Harrow semi or specifying for a London commercial venue, the result is the same — a space that feels completely reimagined.
