Traditional framing methods have been successfully used in the construction of buildings for a millennia and are once again in vogue. At UK Timber Limited our Sawyers and TRADA Graders have decades of experience between them, enabling us to accommodate almost any request in the shortest time frame across the industry with an eye for both the quality of the material that is being used and the finished product. 

We’ve supplied the machined timber for use in many structural applications including 'Grand Designs' projects, historic stately homes and smaller home builds the length and breadth of the UK - Our Customer Projects Gallery will give you an overall view of the services and products that we can offer you.

We operate several Midland based sawmills that cut to order; our Timber Products Calculator enables you to price your own cutting list. You can also take a look at our stock sizes to see if any of them are suitable for your project.

Most other UK based companies import the oak beams that they sell from European countries, primarily France. These beams are transhipped to the UK according to specified cutting lists. At UK Timber, we bypass that whole process, cutting to order in the UK on site and delivering directly to our customers with our own dedicated vehicles, all of which are fitted with cranes for ease of offloading.

Another one of our unique offerings is the ability to order up to lengths of 12.5 metres from our huge stock of trees. All of our structural beams are cut on site from both Oak and Douglas Fir, both materials offering their own specific traits; please feel free to contact our knowledgeable Sales Team to discuss which will suit your requirements the best and for advice that you can rely on. 

We understand that the purchase of oak beams and oak frames is not cheap. Please feel reassured that our expertise and attention to detail coupled with an outstanding, subsidised nationwide delivery service has your every requirement covered. UK Timber Ltd are the right choice of supplier.

    Different Grades of UK Timber Oak

    Green Structural Oak

    A fresh cut oak that has been clear-cut in the last 3 - 6 months, it is of high moisture content and is prone to shrinkage and movement during the drying process. Also known as falling boards, these oaks are used for all sorts of external and landscaping purposes.

    Air Dried Structural Oak

    This oak dries relatively more slowly compared with other types. Machine-sawn and straight, it can easily be cut into different precise dimensions. Sometimes displaying surface checking, splits, a little sap and a few historic bore holes, these flaws will doubtless add a little character to the finished project.

    QP1 Grade Beams

    These oak beams have a minimum of 3 straight edges with tolerance of a small amount of wane to one edge. They are better utilised in the construction industry and for property renovations.

    Fresh Sawn Vs Air-Dried

    UK Timber offers both air dried and fresh sawn oak beams.

    Here is a comparison of these options:

    Fresh Sawn



    • Adaptable for many various projects
    • Used where some movement and shrinkage is permitted
    • It dries slowly and adjusts naturally
    • Used for framing and restoration
    • Suitable for more sensitive situations
    • The beams are dried in square sections for 1-4 years
    • Appropriate for projects that require an aged aesthetic
  • Construction Timber

    Treated structural graded softwood that is used for construction purposes and for internal building work is known as carcassing timber. 

    UK Timber hold large stocks of both C16 carcassing timber and C24 graded carcassing timber.
