Our C16/C24 structural grade timber is a high quality, cost-effective timber product. It is ideal for smaller indoor construction projects as well as for applications that require structural grade timber such as roof or floor joist installation.  All of our C16/C24 timber is typically imported from Sweden and the Baltics where it has been grown slowly. This produces growth rings that are more tightly packed together, producing a high quality of timber. C16/C24 timber has a smooth outside edge and has been pressure treated for enhanced durability.
