Close up of a grade stamp on a piece of timber
Some of our stock has been graded in the country of origin, and each piece is stamped appropriately. Some is graded at our premises by our TRADA approved grader and again is stamped accordingly.
C16 and C24 are softwood strength classes. A strength class is a group of species/strength grade combinations which have similar strength/mechanical properties. There are different C strength classes however C16 and C24 are the two most frequently used. These are the two grades that we supply in this context.
SC3 and SC4 are the old strength classes that have been superseded by the European strength classes as described above. SC3 is approximately equivalent to C16 and SC4 is approximately equivalent to C24.
