What Set’s Us Apart From The Rest

Steel Connections is a family run business with over 30 years’ experience in the construction industry. Over the last 9 years, the team have been developing their skills in Portal Frame Calculations and Design, with input into one of the leading portal frame design software.

John Harrison, the man behind Steel Connections spent a few years in Australia drawing structural steel buildings and learning the associated codes. On his return he secured a position of structural draftsman at one of the most prestigious portal frame building companies in the UK where he gained extensive knowledge on how to do the job to all current British standards.

We have years of experience in both AutoCAD, Autodesk Inventor and Tekla. We have helped many companies gain their CE Mark in the design area to increase their sales figures.
