Specialist Self-Storage Steel Structures
The UK self-storage market is evolving rapidly, demanding faster build times, rigorous standardisation, and highly efficient use of space. At STONNA Steel Structures, we position ourselves as the definitive specialist in this niche. We understand the specific layouts, grid systems, and load-bearing requirements that major operators demand.
Whether you are developing a 30,000 sq ft urban facility or a 100,000+ sq ft multi-story storage centre, we manage the entire steel package. Because we partner with a vetted network of UK fabricators rather than relying on a single in-house facility, we offer unparalleled capacity and agility.
Industrial & Commercial Mezzanine Floors
E-commerce logistics, manufacturing, and commercial warehousing require intelligent space utilisation. STONNA delivers heavy-duty, structural steel mezzanine floors designed to seamlessly integrate into your existing or new-build facilities.
We don’t just supply steel; we provide a fully coordinated service. Working closely with structural engineers and principal contractors, we ensure that every mezzanine structure is optimised for weight, cost, and buildability.
Structural Alterations & Warehouse Conversions
Repurposing existing buildings for modern logistics or self-storage often requires complex structural alterations. STONNA specialises in the highly technical steelwork packages necessary to upgrade, strengthen, or extend existing commercial frames.
These projects carry unique risks and require proactive problem-solving. Our Director-led project management team works hands-on with architects and engineers to interrogate existing structures, designing practical, safe methods for installing new steelwork within constrained environments.
Structural Design Coordination & Value Engineering
The most expensive mistakes in steel construction happen before the steel is even ordered. At STONNA, our biggest value-add is our early-stage design intelligence. We invite architects, engineers, and developers to engage with us long before the final tender is issued.
We conduct rigorous design rationalisation exercises. By interrogating the drawings early, we identify opportunities to reduce steel tonnage, simplify connections, and improve overall buildability.
Expert Site Management & Steel Installation
A brilliant steel design is useless without flawless execution. While our trusted partners manufacture the steel, STONNA’s core focus is on total site control. Our project management is Director-led, meaning your site is overseen by highly qualified industry experts who treat your timeline as their own.
We coordinate all on-site logistics, manage crane operations and steel erection teams, and enforce strict health and safety protocols to deliver your project safely and on schedule.
