Product Description and Features

LYSAGHT TOPSPAN® 61 is a 61mm deep profile used in the smaller framed shed and awnings market and is a convenient size to satisfy the niche market need of a section between a small purlin and large batten.

It is popular in the residential and rural markets and has found other applications such as framing, long-span plasterboard battens, fencing and handyman applications. It is commonly called a “garage batten”.

The bottom flanges have two longitudinal stiffeners/grooves for improved performance, but also act as a guide for the correct positioning of the fixing fasteners. Lapping (structural) is simple and will ensure continuity and straightness and further improve the capacity of the configuration. The lapping results in a precise snug fit without deformation of the profile and only nominal step at the lap.
