7.2.4Protection of trusses

Trusses shall be protected from damage.

Where the trusses or timber members are damaged, they should be rejected and not repaired. To avoid distortion and to prevent damage, trusses should be:

  • protected against weather to prevent the corrosion of truss plates and the deterioration of the timber
  • adequately ventilated during storage
  • stored clear of the ground
  • stored vertically and propped
  • stored with level bearers under the joints
  • carried upright (fasteners can loosen when carried flat).
