The White Book – Floor Deck Specification

Floor Deck Design Guide and Tables

This ‘White Book’ has been developed as a quick reference tool to be used by architects, engineers and specifiers when looking for a quick concept design for a composite slab and has been recently updated to include the new TR50 and revised R51+ profile.


Innovative User Experience!

A unique process has been developed to allow the reader to gain relevant information in a three-step process using ‘never seen before’ graphs as a visual aid to help understand what can be achieved in different scenarios. Created by our Technical duo, Jamie Turner (Technical Director) and Thom Rigden (Technical Engineer), Jamie said;

‘We wanted to create something more than just a book of numbers.  The guide helps with an understanding of the process, how to use the guide so they can gain what they are looking for’.


Client Feedback
