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.
The variation you require will determine the exact lead time and delivery method.
Most orders arrive within 3-4 days, the maximum is 7 days. Please get in touch before you order if you need a specifc delivery date.
Delivery charges vary by postcode. To find out the delivery charge, add the item(s) you require to your basket and select CALCULATE SHIPPING at the bottom of the page.
Some orders are delivered on our own vehicles based in Leicestershire and Cheshire. We also use carriers including Yodel and Tuffnells. For some sizes and locations we use regional distributors.
