external steel staircases & fire escapes
At Mammoth Steel, we specialise in the design, fabrication and installation of bespoke external steel staircases, access stairs and fire escapes for residential, commercial and industrial properties throughout the UK.
From practical external access staircases to purpose-built emergency escape routes, we deliver robust steel solutions tailored to the requirements of each project.
Working with architects, developers, main contractors and property owners, we combine technical expertise, precision fabrication and quality craftsmanship to create durable staircases designed for long-term outdoor use.
Our external staircases can incorporate galvanised steelwork, anti-slip treads, steel balustrades and a range of protective finishes, depending on the project’s requirements.
Based in Chester, Cheshire, we provide a comprehensive service from initial design coordination through to fabrication and professional on-site installation.
Our external staircases
From everyday external access to specialist industrial staircases and emergency escape routes, Mammoth Steel provides bespoke steel staircase solutions for a wide range of residential, commercial and industrial applications.
Each staircase is designed around the building, its intended use and the specific requirements of the project, combining structural strength, practical functionality and long-lasting durability.
external access STAIRCASES
Bespoke external steel staircases designed to provide practical, reliable access to upper floors, terraces, balconies and building entrances. Available with galvanised steel structures, anti-slip treads and a choice of balustrades and protective finishes to suit residential and commercial properties.
steel fire escapes
Purpose-designed external steel fire escape staircases for commercial, industrial and residential buildings. Working alongside the project team, we develop bespoke staircase solutions that consider the building's fire strategy, access requirements and applicable regulations, with durable steel construction suited to external environments.
industrial steel staircaSes
Heavy-duty steel staircases, platforms and landings. Designed for industrial facilities, warehouses, plant areas and operational environments. Fabricated to suit specific site requirements, with options including galvanised steelwork, open-grid treads, robust handrails and protective finishes for demanding applications.
From concept to completion
At Mammoth Steel, we understand that external staircases must combine structural strength, durability and practical functionality.
From initial design coordination to precision fabrication and professional installation, we work alongside architects, engineers and contractors to deliver bespoke steel staircase solutions tailored to the building, its intended use and the project’s technical requirements.
step 1. design & drawings
We work with your project team to develop external staircase designs that consider building access, structural connections, dimensions, materials and environmental exposure.
For staircases intended as emergency escape routes, we coordinate with the relevant design professionals to address the project’s fire strategy and applicable regulatory requirements.
step 2. precision fabrication
Once the design and specifications are approved, each staircase is fabricated with precision and attention to detail.
Using quality steelwork and suitable protective finishes, including hot-dip galvanising where specified, we create durable staircase structures designed to withstand the demands of external environments.
step 3. expert installation
Our experienced installation teams coordinate with site management and other trades to deliver safe, efficient on-site installation.
From positioning and securing structural components to fitting treads, handrails and balustrades, we focus on accurate assembly and a high-quality finished result.
Frequently asked questions
-
Hot-dip galvanising is a popular choice for external steel staircases because it provides long-lasting protection against corrosion. Depending on the location, environmental conditions and appearance required, we can discuss galvanised steelwork and other suitable protective finishes for your project.
-
Planning permission requirements depend on the property, its location and the nature of the proposed staircase. Some external staircases require planning permission, particularly where they affect a building's appearance, provide new access or serve as a fire escape. We recommend checking with your local planning authority before proceeding. Building Regulations approval may also be required.
-
Yes. Mammoth Steel can provide bespoke external steel staircases intended for use as emergency escape routes. These must be designed to suit the building's fire strategy and applicable regulatory requirements. We work with the relevant project professionals to coordinate the staircase specification, fabrication and installation requirements.
-
A well-designed and properly maintained external steel staircase can provide many years of reliable service. Its lifespan depends on factors including the environment, steel specification, protective coating, installation quality and ongoing maintenance. Hot-dip galvanising is often specified to improve corrosion resistance and reduce maintenance requirements.
