C24 Timber & Long Lengths
Timber is graded in strength classes, relative to BS EN 14081-1: 2005, ie C16 or the stronger C24 grade. These grades denote a group of species / strength grade combinations which have similar strength / mechanical properties. C16 graded timber is kiln dried and is primarily used for internal building work, mainly in floor and roof joists. The timber is usually machine graded or can be visually graded, having regard to criteria, such as the number of knots, fissures and slope of the grain etc.
Please note: Graded timber is sold untreated unless stated otherwise.
