It’s all about the PEFC Structural Oak stock…

Our structural stock is made up of over 500 green, semi-seasoned & seasoned stock beams available for selection from our yard or online. Sections from 100 x 100mm’s to 350 x 350mm’s in regular & irregular sizes and in lengths from 1.0 to 7.0m standard and longer, including 75, 150 & 200mm thick waney edge curves for bracing.

Oak Posts and Beams

Most of structural beam Oak is milled in France by our partner sawmills from French PEFC logs, to our specification. The semi-seasoned & seasoned stock is srouced from the same mills, who lay down stock year on year for French customers (who will only use air dried!) which means that beyond our own stock, we have a vast structural timber resource to draw from. our curve stock is  75, 150 & 200mm waney edge naturally grown in fresh sawn and seasoned.

Structural Oak Grades

Our structural Oak stocks are graded on request to TH2 (strength class D18) and TH1 (D24) for small sections* or THB (D24) and THA (D30) for large* sections which are standard structural grades that cover service class 2&3 (TRADA  WIS 1-17). We have two qualified graders on hand to grade timber if required. If you’re unsure about grading, call us to speak to a grader on 01730 816941

Oak Beam Prices and Selecting from Stock

Every piece of structural timber has been measured, tagged and listed on our stock system with dimensions, grade and price £/m3. This means you can select beams online without ever having to leave the comfort of your desk, your workshop or your cosy van.

Use the picking list on the stock search tool (the +signs on the right) to make your choices, and then let Graham do all the hard work (good old Graham!) whilst you get on with something more pressing instead.

We’ll call as soon as your beams are ready to collect or we’ll arrange delivery to the site, it’s up to you.


Weekly Deliveries

If it’s in stock, our structural Oak is cut to order based on specific requirements and delivered on a weekly basis. We work closely with our partner sawmills to achieve the highest quality timber. this means that if we don’t have what you need in stock, you won’t be twiddling yout thumbs for long! Your order will be ready to be collected or delivered the following week**

**Notwithstanding ferry strikes, blizzards, flu epidemics & the ever plentiful French Bank holiday ( & a couple of our own thrown in for good measure) our haulier is pretty good at getting your timber to us quick-sharpish on a Monday morning (thanks Alain, Sandrine & Tomasz!)


Get a quote?  send us your cutting list and we’ll get back to you pronto with the price and availability.

If you’re just pricing, that’s fine. We’ll leave your quotes on file and we’ll call you in a month to check the project’s still live. You can come back to it anytime, and when you do need to order we’ll be bringing in a lorry every Monday morning** so as long as you’ve placed your order before the previous Wednesday pm we can usually squeeze you in!
