About Valley Structures Limited

Valley Structures was founded by two highly experienced structural steel detailers with more than 50 years of combined experience working in the industry in the UK and Australia.


Our careers have included detailing and project management roles with leading structural steel companies, working on projects ranging from smaller steelwork packages to major and technically demanding structures.


That experience is at the heart of how we work today: practical, accurate detailing backed by an understanding of what happens to the steel once the drawings leave the office.


How we work

We believe good detailing is about more than producing drawings. It is about understanding the structure, anticipating problems, communicating clearly and producing information that works in the real world.
We work closely with clients and project teams, adapting our approach to suit their existing standards, software, processes and project requirements.
