Strategic Partnering
At STONNA, we don’t just act as a traditional subcontractor; we operate as a strategic partner. We build strong, lasting relationships with self-storage operators, main contractors, architects, and structural engineers.
Our partnering philosophy is based on early engagement. By involving us before the tender stage, we provide critical input on budget forecasting, steel tonnage, and buildability. Our agile supply chain—partnering with multiple vetted UK fabricators—means we offer you superior capacity flexibility, reduced risk, and better value engineering from day one.
Agile Project Management
Delivering specialised steel packages for self-storage and mezzanine projects requires a meticulous and complex delivery process.
From the moment you engage STONNA, our dedicated contracts team takes ownership. We establish a robust programme outlining clear milestones, from final design approval and fabrication slots to logistics and installation dates. Because we aren’t distracted by running our own fabrication plant, our project managers remain 100% focused on coordinating the supply chain, communicating with your team, and ensuring the project stays strictly on schedule and within budget.
Site Management & Installation
Flawless on-site execution is the final, critical step. Our highly experienced, fully accredited site managers and erecting teams take complete control of the installation process.
We manage all on-site logistics, crane operations, steel erection, and subcontractor coordination to ensure a smooth, disruption-free build. Safety is not just a policy; it is our primary operational metric. We operate under strict RAMS and guarantee that every steel package is installed to the highest industry standards.
Director-Led & Dynamic
We understand the dynamic nature of commercial developments and warehouse conversions. Change is inevitable, which is why our agile model is designed to react quickly, providing solutions rather than delays.
STONNA benefits from Director-led project management. This means your project is overseen by industry experts who take a hands-on approach to problem-solving. Our contract team members are highly qualified, utilising their deep sector knowledge for your benefit. With a team that is fully accredited and highly proficient in site management safety, you can trust STONNA to deliver certainty in an unpredictable environment.
