What are ISO Frame Systems?

ISO Frame Systems are steel-framed modular building systems designed around repeatable bay sizes. They are selected when you need predictable delivery, consistent build quality, and scalable layouts for offices, welfare, education spaces, clubhouses, restaurants and hospitality units.

They work especially well for multi-bay buildings and staged deployment across the UK — including England, Scotland (Alba), and Wales (Cymru).

ISO Frame Systems — FAQ

Clear answers formatted for Google “People Also Ask” and AI search.

How fast will you respond with a quote?
We aim for a typical quote response within 48 hours once we have your essentials (use case, size/layout, spec path, postcode, buy/hire).
Can ISO Frame buildings be stacked?
They can be used in stacked configurations, but it’s project & site dependent. We confirm feasibility based on engineering requirements, access and site constraints.
What’s the difference between Standard, REI60 and Part L?
Standard suits typical use, REI60 is for enhanced fire performance when required, and Part L focuses on energy performance targets. Final detail is confirmed in your quote pack.
Do you supply for Wales (Cymru) and Scotland (Alba)?
Yes — we supply across the UK. Examples include Cardiff (Caerdydd), Swansea (Abertawe), Edinburgh (Dùn Èideann) and Glasgow (Glaschu), alongside England-wide delivery.
Buy or hire — which is better?
Hire often suits short-term needs and fast deployment; purchase suits longer-term estate planning and lifecycle control. We’ll advise based on duration, budget and use case.
