Timber batten sizes
We normally several different section sizes of "batten" in stock, the most popular being the 25 x 50mm variants. Other popular battens are the 19mm x 38mm and 25mm x 38mm.
For a roof with rafter centres up to 600mm then 25mm x 50mm battens should be used for natural and fibre cement slate, interlocking clay and concrete tiles. These may be Type A batten, 25 x 50, and the Type A BS8417 stamp confirms that the battens have been graded to this standard. Then comes the colour battens, the 25 x 50 (actual 25 x 48mm) , coloured battens (ours are usually yellow) signify that these battes have reached BS 5534 grade. Note that the colour of the batten is an indication of quality, but it is the individually stamped battens that confirm the grading. It is the Contractors responsibility to ensure that the battens selected match the requirements specified on the contractors materials listing.

Pressure treatment of battens
These timbers are all pressure treated with Tanalith E, or similar, timber preservative. It is important to the durability of the batten that any cross cuts are treated with two coats of end-grain treatment are applied. These timbers are tanalised for situations where the timber may be subjected to the occasional risk of wetting from rain. However, they are not intended for prolonged exposure to rain or stored (or used) in ground contact.
