ISO certificates get mentioned a lot

But what matters is what it does for your projects.

At Steel Dynamics UK, we’re accredited and certified to recognised standards for quality, safety and controlled supply into demanding sectors. It’s independent proof that our processes are defined, audited and repeatable.

Here’s what we hold and why customers care:

✅ ISO 9001 – quality management with consistent, customer-focused processes

✅ ISO 19443 – quality management aligned to nuclear sector supply chains

✅ AS9100D – quality management for aerospace and defence requirements

✅ ISO 45001 – occupational health and safety systems that protect people at work

✅ EN 1090 – certification for structural steel components and traceability requirements

Keeping these in place takes ongoing audits and continuous improvement. We do it because it reduces risk for customers and it backs up what we say we can deliver.
