TOP SPAN BATTENS

top span batten

Queensland Sheet Metal Top Span Battens are commonly used in industrial applications as they have a larger base metal thickness than standard Roofing Battens.

These are made from hi-tensile Australian steel and they are very strong. Queensland Sheet Metal Top Span Battens come in a variety of sizes, can be made to custom specifications and are manufactured Australian steel.

Features

  • A textured surface makes installation easy when fixing the cladding
  • The return edge provides safety and rigidity
  • Available in stock lengths with mitred ends for easy installation at hips and valleys

Lapping Battens

To minimise cutting, lay the battens in one direction starting from one end of the roof. The overlap must be supported over a truss or rafter. The minimum overlap is 100mm.

Note: If additional fall protection is required on steel sheet roofs, Ceiling Battens may be fixed intermittently between Roofing Battens giving a batten spacing no greater than 600mm. Roofing Battens are suitable for non-cyclonic conditions up to and including W41 (N3).
