General information

Galvanized steel strap used to avoid roof uplift by strong wind in wooden houses. To achieve an efficient wind resistance, the walls and the basement must also be of a sufficient weight and strength.

The strap is provided with pre-punched holes for nailing.

Choose the type of galvanization according to the environment. In very high corrosive environment, stainless steel straps would be preferred.

The strap can be found in different length, i.e.10m coil or 30m coil.

Calculate the total needed length:

  • The cut length of the strap shall be equal to twice the "End Length" as defined below plus the clear span dimension (if any).
  • The minimum "End Length" for each end of the strap should provide enough space for 6 nails of 75mm or 7 nails of 60mm.

Other acceptable width and thickness:

  • The minimum section should be 30mm² (i.e. 1x32=32mm²)
  • Minimum width: 25mm, maximum width:50mm
  • Minimum thickness: 0.6mm (G25), maximum thickness: 1.16mm (G19)
  • It must be possible to bend and twist the strap by hand to fit the exact shape of the timbers.
  • If need be one can double the strap to increase the strength.
