Wood grade

[Eld]

Are C24 and K24 the same thing? Does anyone have a link that explains the requirements for a specific timber grading?

Is C24 and K24 the same thing?

As far as I understand, yes.

Does anyone have a link that explains the requirements for a certain timber grading?

Don't know if this might help, but it's worth a try
