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

VS

Air-dried

  • 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

  • Structural Green Oak...

    Our numerous sawmills cut to standard and custom sizes in green English and French oak (quercus robur). We can cut structural green oak beams and oak posts to any size required and our on-site graders will happily grade according to TRADA's THA (D40) or THB (D30) structural requirements amongst others for an additional charge. Look no further for fresh sawn European and English oak for structural oak beams, oak boards and oak posts. We always hold substantial amounts of English and European oak beams, oak trees to cut any size order from single beams to full truck loads.

  • Air Dried Oak Beams

    UK Timber hold huge stocks of air dried European and English (quercus robur) structural oak beams and posts and are probably the UK's leading supplier of structural beam oak. It is available in most dimensions and is perfect for all structural beam uses, any sizes unavailable from stock can be ordered from our partner mills on the continent or re-cut from larger dimension stock (this will mean different colours are present on the re-cut face and it will expose moisture variations). Please remember that due to the lengthy natural drying process that air dried beams will have some surface checking, splits, possibly a little sap and may have a few historic bore holes - all of these characteristics make air dried oak one of the most popular ways of adding character to a new build or renovation and in no way detract from its structural qualities.

  • Oak Boards

    Our oak beam production produces many boards from the edges of the tree. Otherwise known as falling boards, they are air dried then kilned for our oak flooring and moulding production. We generally have a surplus which creates an opportunity for UK Timber customers to buy high quality fresh sawn oak boards, air dried oak boards and kiln dried oak boards at a significantly lower price than you would pay for dry material - they can be used for all sorts of external or landscaping uses or you can dry them personally to use for joinery and carpentry and save a lot of money!

  • Oak Beam Mantels

    Our oak beam fireplace mantels are made to order. As these are created from a natural product, each piece will be different. The mantels are made from dried pieces of oak, so they will contain surface cracks, splits and knots. There may also be one or two waney edges.

    Following lentghs below are available in section sizes - 100x75; 125x125; 150x150; 200x50; 125x100; 200x125; and 225x125. Can also be cut to custom size using our custom cutting calculator.

    Our mantels are available in a rough sawn finish, or a planed all round finish.

    These oak beam mantel pieces for fireplace surrounds are created from partially dried new untreated oak sleepers. They are left untreated so that you can finish with your own favourite colour - by using either an oil, stain, or wax. We do supply a range of Treatex Hard Wax Oils which are available in a selection of colour tones and sizes - you will also find these on our website.
