Applications
The range of Stramit® Top Hats is ideal for small to medium sized sheds and similar structures. Stramit® Roof Battens have been developed specifically for domestic applications but may be used in small commercial structures as well, with Stramit® Cyclonic Roof Battens having enhanced performance to endure the repeated loadings that can be experienced in tropical cyclones. Stramit® Ceiling Battensare intended for use with plasterboard sheeting in both domestic and commercial situations.
Materials
Stramit® Top Hats & Battensare manufactured from high-tensile (G550/G500) steel with either AZ150 zinc-aluminium alloy or Z350 galvanised coating in full conformance with AS1397.
Specification
Maintaining the structural integrity of a building structure is important. Even an apparently small change in product material or dimensions can lead to a considerable reduction in performance. One of the best ways to ensure structural adequacy is to prepare and enforce an appropriate specification for structural components.
A suggested specification is:
“All top hats/roof battens/ceiling battens shall be Stramit sections or approved equivalent supported by submission of section properties and capacity calculations/data in accordance with AS4600,AS3623 and AS1562. All sections shall be produced from high-tensile G500/G550 steel with a galvanised/zinc-aluminium alloy coating conforming to AS1397. All sections must be installed in accordance with the manufacturers recommendations with particular reference to the number, size, grade and positioning of fasteners.”
Adverse Conditions
Stramit® Top Hats and Battens will give excellent durability in most applications. In exposed conditions, unwashed areas subject to salt-laden air or other corrosive matter may need additional protection. Stramit® Top Hats and Battensare not recommended for use in enclosed areas within 450mm of moist soil.
