Steel Stairs
Steel stairs
We design and fabricate high-quality steel staircases for small to mid-size developments across the UK. Whether you’re working on a residential refurbishment or a commercial fit-out, we can supply and install the right stair solution to suit your space, budget, and spec
Popular Staircase Types We Supply & Install
We’ve worked with small developers across the UK on hundreds of residential and commercial projects. Below are the most sought-after stair types we design and fabricate — each suited to a specific kind of build, layout, or design spec. Our team can advise you on the right choice for your project, and tailor every staircase to your measurements, finishes, and budget.
Central Spine Stairs
Why they’re popular:
Central spine stairs are a go-to for modern developments that want to create a clean, open look. The steel spine runs directly under the centre of each tread, making the staircase appear to float while still providing solid structural support.
Best suited for:
Ideal for contemporary homes, duplex apartments, or extensions where the staircase is a focal point. Our clients often pair these with timber treads and glass balustrades for a high-end, minimalist finish. We’ve supplied these for both new builds and luxury refurbishments.
Mono Stringer Stairs
Why they’re popular:
Similar to central spine stairs but using a single side-mounted steel stringer, these offer an elegant profile with even more open space underneath. Often used to complement glass walls or open-plan living spaces.
Best suited for:
Great in properties where light and space are key features — especially where you want the staircase to feel like part of the interior design, not just a functional necessity. We fabricate these to exact spec, including custom brackets, handrails and finishes.
Zig-Zag (Cut String) Stairs
Why they’re popular:
With treads cut in a clean, geometric zig-zag, this style gives a very sharp, architectural look. The steel structure is usually exposed and becomes part of the visual appeal.
Best suited for:
Used in homes and developments where design is a big focus. Commonly chosen for statement staircases in open spaces or entrance halls. We’ve built these with timber, stone and composite treads — always engineered to comply with UK Building Regs.
Cantilevered Stairs
Why they’re popular:
Each tread is fixed into a load-bearing wall with no visible supports, giving the ultimate floating look. When paired with hidden steel reinforcement and seamless finishes, the result is striking.
Best suited for:
Perfect for minimalist homes and high-end developments that want to impress. We provide the full structural support and collaborate with your engineer or architect to make sure everything meets safety standards and installation is flawless.
Straight Flight Stairs (Custom Finishes)
Why they’re popular:
Simple doesn’t mean boring. A straight flight stair can be elevated with quality materials and clever design. This type is fast to fabricate, easy to install, and very cost-efficient.
Best suited for:
Ideal for residential builds where practicality is key. We often supply these with custom finishes — from powder-coated mild steel to oak-clad treads or even anti-slip nosings — tailored to suit the final spec and budget.
L-Shaped & U-Shaped Stairs
Why they’re popular:
These stairs turn at a landing, breaking up a long run and making better use of tight spaces. They also allow for safer, more manageable rises between floors.
Best suited for:
Townhouses, split-level homes and compact developments where straight stairs won’t fit. We fabricate these in sections for easy transport and quick site assembly, with every component tailored to your drawings.
Spiral Stairs (Architectural & Space-Saving)
Why they’re popular:
Spiral stairs are a functional solution when space is tight, but also work as a striking design feature. Steel is strong enough to support tight curves, slim profiles, and even fully enclosed options.
Best suited for:
Loft conversions, garden flats, or internal feature stairs in design-led homes. We build these with exacting precision to ensure comfortable access, compliance with regs, and a visually smooth spiral.
External Steel Stairs (Commercial & Residential)
Why they’re popular:
Designed to withstand the elements, these stairs are typically hot-dip galvanised or powder-coated for long-term durability. They provide safe, low-maintenance access and are often required by planning or fire regulations.
Best suited for:
Schools, warehouses, apartment blocks, and roof terrace access. We have experience supplying external staircases for both primary and secondary egress, including anti-slip treads, drainage-friendly designs, and compliant balustrades. All fabricated to current Building Regs and CE marked where required.
Fire Escape Stairs
Why they’re important:
A critical safety feature for any multi-storey building. These are engineered for emergency use, often with grating treads, landings, and high-visibility finishes. Built for strength, compliance, and durability.
Best Suited for:
Apartment buildings, HMOs, commercial units and schools. We fabricate fire escape stairs in-line with current legislation, working with you or your fire consultant to make sure everything meets spec. Our experience includes both retrofit fire escapes and staircases built into new developments.
