May 09 2013 MetSPEC Euro1 Launched We have now launched the latest version of our design software MetSPEC EURO1, which optimises the design of purlins, side rails and mezzanine floor joists to the Eurocodes. We know that the switch to harmonised European standards for construction is presenting a huge challenge to the steel construction industry. Our aim is to help engineers get used to the new requirements and method of working. Engineers and specifiers can rest assured knowing that MetSPEC EURO1 load capacities are based on design analysis to BS EN 1993-1-3.
