Strength class C18

Strength class C18 can be used for load-bearing structures that do not require high strength, or where it is possible to use large dimensions or short lengths. The strength class can also be used for wall studs in load-bearing structures if the requirements concerning deformation are not high.

C18 is a strength class where factors that affect the strength of the construction timber are permitted to a moderate extent.

Deformation is permitted to a much greater extent than in strength classes C24, C30 and C35.

In visual grading, individual knots are permitted to be equal to 2/5 of the construction timber’s width and 4/5 of its thickness. The principles behind mechanical grading mean that the number of knots is often higher than would be permitted in visual grading.

Top ruptures must not be present in the outer 1/4 of the construction timber’s width.
