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.
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.
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.”
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.
