Guidance, Support and Specification Tools

A wikipedia-style source of comprehensive guidance on design and installation of composite metal floor and structural roof deck - the TGN (Technical Guidance Notes) provides information from start to finish of a contract journey, aimed to aid our customers and engineers when undertaking work prior to specification, design or scintillation of products on site, to ensure best practice is adhered too and issues are restricted to the minimum.
The TGN offers design information covering the relevant and most up to date British Standards, Eurocodes and industry guidance documents including: BS5950, EC4 and SCI P300.


SMD Elements® is our set of supportive design tools, to aid engineers and designers when choosing products, checking data and running detailed calculations using our powerful, in-house developed, design software.
We have a host of technical support tools including interactive online design tables, mobile apps for Android and Apple devices along with our trusty downloadable design software, to support designers at different stages of the design stage. Below lists all our tools and software available.


This tool provides a quick reference to provide product suggestions based on typical spans, loadings and other governing criteria.


Our Online Design Tables allows users to lookup span data quickly, based on set design criteria.


Using data from our standard design tables, these helpful graphs aids the designer to visually identify span ranges of our products.


Developed by SMD, this application provides a tool to carry out detailed design calculations for both floor and roof deck products.
