Balance Safety and Style With a Metal External Staircase
An external staircase is more than just a way to get from one level to another. It is a vital access point, a safety measure, and often a highly visible part of a building’s exterior.
At Formost Fabrications, we design and install bespoke outdoor staircases that combine strength, compliance and architectural appeal, giving our clients peace of mind as well as practical access.
Why Choose a Metal External Staircase
A well-designed external metal staircase offers clear advantages over timber or concrete alternatives. Steel staircases are strong, durable and adaptable to almost any setting. When fabricated in galvanised steel, they resist corrosion and stand up to decades of weather exposure with minimal maintenance.
For commercial and industrial buildings, this makes them the ideal solution for fire escapes, plantroom access, and secondary entrances. For residential projects, a bespoke outdoor staircase can provide a safe and attractive route to gardens, roof terraces or upper floors.
Spiral Staircases for Space-Saving Access
In many settings, space is limited. This is where spiral staircases excel. An external spiral staircase can provide safe access without taking up the footprint of a straight-run design. These staircases are popular for both domestic and commercial properties where style and efficiency matter.
We fabricate spiral staircases in mild or stainless steel, with the option of galvanised steel for weather protection. With the right detailing, they can be as much an architectural feature as a practical necessity.
Fire Escapes That Perform When It Matters
A significant proportion of external staircases are specified as fire escapes. In these cases, performance and compliance are paramount. We fabricate staircases with non-slip treads, guardrails, and the strength to handle emergency loads. Every design is built in line with UK building regulations, giving facilities managers and building owners confidence that their escape routes are safe and reliable.
Our external metal staircases can be tailored to fit restricted spaces, unusual wall layouts or multi-level exits, ensuring compliance without compromise.
Understanding Staircase Cost
Clients often ask about staircase prices and how much an external staircase might cost. The answer depends on several factors, including the size of the staircase, whether it is a straight run or spiral, the choice of materials, and the type of finish.
A small domestic outdoor staircase fabricated in mild steel will have a very different cost to a large commercial fire escape built in galvanised steel with multiple landings. At Formost Fabrications, we provide clear, detailed quotations at the design stage so there are no surprises later.
Custom Design and Fabrication
Every staircase we make is bespoke. We start with a site survey, model the design in CAD, and then fabricate each component in our Surrey workshop. This allows us to adjust layouts, incorporate handrails, and ensure everything integrates seamlessly with the building.
From compact spiral staircases for urban sites to large-scale external metal staircases with multiple access points, we deliver projects tailored to client needs. With in-house control over fabrication and finishing, we guarantee accuracy and consistency at every stage.
