TRA publishes a wide range of technical advice and product information on trussed rafters and metal web joists, helping grow the market for quality assured products and professional services. See our latest publications below.

TRA Ireland’s primary aim is to maintain and raise standards within the industry. The market in Ireland has some specific technical requirements but all Trussed Rafters and Metal Web use common European manufacturing and design standards. Roof styles, spans and the popularity of attic trusses for room in the room living are also very similar throughout Ireland and the UK.

Building Regulations and the requirements imposed by bodies such as HomeBond and the Health & Safety Authority are the main areas of difference and where possible this is highlighted in the TRA advice and guidance.  Members position regarding Ancillary Certificates.

We are proud as TRA members to offer products which are:

  • Manufactured to common European standards
  • Designed to latest common European Design Codes
  • Use the most up-to-date design software and technology
  • Use structural softwood sourced from sustainable forests throughout Europe
