Can anyone tell me what the new gradings are for CRS, as I gather the ratings changed a few years ago? I know they range from C16 - C24 but don't know how they relate to some old drawings I have.
The timbers are:
100 x 50mm at 350 CRS
175 x 50mm at 350 CRS
100 x 50mm at 500 CRS
Many thanks, if anyone knows!!
