Manufactured timber roof trusses provide a structurally efficient alternative to timber beams. They place greater emphasis on axial loading of members and less on bending.

The advantages of trusses include the following:

  • They are strong, but light to erect.
  • They can be made to suit most roof shapes.
  • There is less on-site fabrication, therefore less site labour is required.
  • They are less affected by bad weather.
  • Factory production allows automated production.
  • Better quality control is possible.
  • Trusses make maximum structural use of the timber.
  • Trusses are capable of long spans.
  • Internal walls are usually non-load bearing, therefore lighter weight internal walls are possible.
