25×50 Treated Type A Batten 4.8 m

25 x 50mm Treated Type A Batten

A rough-sawn, preservative-treated softwood batten manufactured to the standard specification used across the UK construction and roofing industries.

Dimensions

The 25 x 50mm profile refers to a thickness of 25mm and a width of 50mm — approximately 1″ x 2″ in imperial terms. These are nominal sawn sizes, so the batten has a rough-sawn finish rather than a smooth, planed surface.

Treatment and grading

Type A designation confirms the batten is pressure-treated with preservative for protection against rot and insect attack, making it suitable for use in roofing applications where durability is essential. The 25 x 50mm size is the most widely specified roofing batten dimension in the UK, used for fixing roof tiles and slates, as well as general framing, cladding support, and fencing work.
