MetSPEC 14

Purlins & Side Rails: Software

MetSPEC Roof Purlins Design Software

Our software optimises the design of purlins roof systems, side rails and mezzanine floor joists. Our latest release incorporates both British Standards and Eurocodes into one piece of software – MetSPEC 14.

MetSPEC 14 is an engineering software designed specifically to assist engineers in planning, designing and creating construction projects using detailed models. Structural engineers can visualise projects and calculate purlin requirements effectively with this updated software. MetSPEC 14 also allows engineers to create load tables in a time effective manner minimising costs and increasing workplace productivity.

Developed with a user friendly format, the software incorporates project management features, british standards, eurocodes, and also produces calculations in a fast and easy way. MetSPEC 14 is an ideal solution for structural engineers wanting to optimise their designs and increase their time capacity.

All new section sizes have also been added into the new software.

The software optimises the steel design to the following British Standards and Eurocodes:

British Standards:

  • BS5950 part 5: Code of practice for design of cold formed thin gauge sections
  • BS6399 part 2: Code of practice for wind loads
  • BS6399 part 3: Code of practice for imposed roof loads


  • BS EN 1990: Basis of structural design
  • BS EN 1993-1-1: General rules and rules for buildings
  • BS EN 1993-1-3: General rules – Supplementary rules for cold formed members and sheeting

Also incorporating:

  • BS EN 1991-1-1: General Actions – Densities, self-weight, imposed loads for buildings
  • BS EN 1991-1-3: General Actions – Snow loads
  • BS EN 1991-1-4: General Actions – Wind actions

The results of full scale testing and component testing at The University of Strathclyde have been used on the experimental side and various theoretical approaches, first order and second order theories combined with finite element analysis and design analysis to BS EN 1993-1-3 have been used to derive the load capacities.

MetSPEC is compatible with Microsoft Windows 2000 onwards.
