Planed pine battens, pressure-treated with a protective antiseptic (usually green or brown).
Intended for exterior applications: roofing, framing, floor joists, decking, gazebos, etc.

Class AB: Standard construction grade (sound knots are permitted).

The impregnation effectively protects against rot, mold, and wood-boring beetles, so the material can be used outdoors without the need for painting or additional treatment.

The most popular type of impregnated battens for roofing and framing in Northern Europe.
