WebC24 Timber vs. C16 Timber. C24 and C16 are the most popular options for carcassing timber within the UK. Both are comparable but C24 is the superior choice. C16 wood tends to be grown faster, with the forced growth process leading to an increase in knots. This will make the timber in C16 beams less durable, and also make them visually flawed. C16 graded timber allows for a number of defects that may reduce the overall strength of the wood, such as grain deviations and wanes, as well as an unlimited amount of superficial defects that do not affect the strength of the wood, such as blue sap stains and the like.

In metric, however, it is specified as 47mm x 100mm or 50mm x 100mm. This discrepancy is accounted for by the way the wood is cut and prepared. As the 47mm and 50mm are largely interchangeable (due to the minuscule difference between them) either size falls under 4x2.
