As a member of the Trussed Rafter Association (TRA) we adhere to the most stringent principles of best practice and quality assurance. 

The TRA sets a professional benchmark for the trussed rafter and metal web joist industry and as a member, we have been vetted and approved by them.

It means we offer every customer the highest levels of manufacturing excellence and customer service, supplying all structural roof components while the elements of the final trussed rafter are quality assured.

We provide truss designs for all types of companies, from leading volume housebuilders to small developers producing more bespoke designs.  However, once we deliver the trusses it is for the builder to make sure that they are installed safely.

Installing trusses requires specific construction skills which involve working at height and a full site-specific risk assessment must be undertaken before any work commences.  The installation of trussed rafters should only be undertaken by suitably experienced and qualified personnel, such as those with a Level 2 Diploma in Site Carpentry.

Here are some pointers, from the TRA, for installing trusses on your site:

  • Check and read all assembly drawings and information provided by the truss supplier, such as Scotts
  • Ensure all personal protective equipment (PPE) is worn and correctly fitted
  • Ensure scaffolding is in place and signed off
  • A safe working platform within the structure is strongly recommended
  • Ensure hop-ups and scaffolding edge protection are in place
  • After reading the truss layout drawings, identify the easiest starting point using the simplest roof
