Product Description and Features

LYSAGHT TOPSPAN® 40 is a 40mm deep profile used as a roofing batten for residential tiled roof or steel roof. It is commonly called a “roofing batten”.

The top flange of the profile has an embossed surface to make it easier for the steel roofing screws to grip and ‘bite-in’ without slippage during awkward and steep installation angles (up to 25 degrees). Furthermore the embossment improves the slip resistance when the roofers are walking up the roof structure during the placement of the roof tiles or steel roofing.

The lips of the bottom flanges are rounded for improved safety during handling and installation by the tiler trades. The ends of each length are mitre cut for simple installation at hip and valleys. Nominal lapping (non-structural) is simple and will ensure continuity and straightness of fastener alignment.
