We normally keep four different section sizes of batten in stock, and since 2013 we have been supplying two different grades of 25mm x 50mm roofing batten.
Small section battens, 19mm x 38mm and 25mm x 38mm
For some types of roof the 19mm x 38mm and 25mm x 38mm battens have been traditionally used, for example the 25mm x 38mm could be used for plain tiles.
At Southern Timber we sell the 19mm battens primarily for trellis making. Under some circumstances 25mm x 38mm can be used tile roof coverings and FC slate, but it is ultimately the customer’s responsibility to determine what product is required for their application
