Introduction
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.
