FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
