Why Use Oak For Trusses?

Oak combines strength and beauty and has been used by craftsmen in high-end products and buildings for thousands of years. Oak is extremely durable and our trusses will easily last hundreds of years without any maintenance required.

Oak has a rich, warm, golden colour and an attractive, natural, recognisable grain texture. It can be stained to a particular colour or to bring out the grain even further or can be left bare in its natural state.

Quality, Craftsmanship & Construction Techniques

Each oak truss is uniquely and expertly crafted just for you with exceptional attention to detail. Our experienced craftsmen pour their lifelong experience into each truss using traditional, tried and tested joinery techniques, with dowelled mortise and tenon joints.

Each section of oak used in our trusses is planed on each side for a luxuriously smooth finish. We use a high grade of fresh-sawn oak sourced from European forests (it is graded between QPA and QP1 standards, the best available). Such a high grade ensures large, clean beams with no large "dead knots", or anything considered to be defects found in lower grades. Our craftsmen love working with this quality of oak.

Oak Truss Pricing

Oak Timber Structures is proud to be up-front and transparent with its pricing. Use our truss designer above to get an instant, fixed price for your trusses. The only additional cost is delivery which is added during the checkout process and depends on your location in the country.

We started Oak Timber Structures because we spotted a gap in the market for high quality yet affordable oak trusses.

Only a couple of our competitors give indications of their prices up-front. Our pricing is the same regardless of who you are or the size of your project.

Our oak trusses are the same or better quality than many of our competitors for a lower price. There is no catch, we're simply bringing honest, straight forward pricing to the market.

How To Order Your Oak Framed truss

All major cards
securely accepted

Ordering from Oak Timber Structures is straightforward. Nevertheless, our team is on hand to help throughout the process. Here are the simple steps to order a bespoke oak truss:

  1. First, create the oak truss using the designer or send drawings to
  2. For online orders, click ‘Add to Basket’.
  3. Navigate to your shopping basket where you can checkout securely online. We accept all major credit cards excluding American Express (as image). If you run into any checkout issues, please contact us using the online chat or call us and we’ll talk you through the process. Alternatively, you can order over the phone.
  4. We then produce technical drawings for you to sign off and gain approval from a structural engineer if needed. CAD drawings take between 2-3 working days to produce.
  5. If you are unhappy with an aspect of the drawings, we encourage you to call and seek advice from our helpful and friendly staff. They’ll revise the drawings accordingly and send them back to you for re-approval.
  6. Once signed off, we add your structure to the production queue and create it according to the stated lead times. During this time, many people use the approved drawings to get their groundwork in place if required.
  7. Our skilled team assembles the oak truss to make sure there are no issues. This also allows us to code all components for seamless assembly. We then dismantle the truss and organise it into transportable kit form.
  8. If you're running behind schedule, we're happy to store your structure for up to 4 weeks at no extra charge. Please note that we limit storage to 4 weeks. As green oak dries, it shrinks. Shrinkage is normal. In fact, our skilled staff prepares your structure for shrinkage to fuse joints, making them tighter and more robust. Yet, after 4 weeks, joints can become misaligned and harder to assemble, so it's important to limit storage time.
  9. We schedule delivery by liaising with you once your bespoke oak truss is complete.

Understanding The Parts of an Oak Truss

Each part of an oak truss has its own name. Here is what each means:

Tie Beam

Oak Truss Tie Beam

Truss Tie Beam

The tie beam is the large oak beam at the bottom of the truss. This rests on top of your walls, spanning the gap between them and supports the rest of the truss above it. On our designer you can specify the span, or distance it has to cover, its width and its height.

Shaped King Post / King Post / Curved Queen Post

Oak Truss King Post

Truss King Post

The king post is the vertical beam in the centre of the truss. The king post adds to the strength of the truss. The standard King Post is a straight vertical beam, whereas the Shaped King Post is slightly wider at the top and bottom and tapered where the braces (see below) join it.

Queen posts are often used on wider trusses and replace the single King Post with two vertical posts.


Oak Truss Principal Rafters

Truss Rafters

The rafters are the angled beams that the shape of your roof will follow. Rafters extend from the ends of your tie beam to the peak of the truss and are essential to the integrity of the truss.


Oak Truss Braces

Truss Braces

Braces add support to the truss between the rafters and the king post or the rafters and the tie beam. Sometimes they are not structurally required but are included for aesthetic purposes. On our designer you can choose how they are positioned and whether they are curved according to how you'd like your truss to look.

For further information on the mechanics of trusses visit Wikipedia's Truss Page.

Types of Oak Truss We Make

We can make any of the following style of truss (we're slowly adding more types to our 3D designer)

King Post Truss

King Post Truss
King Post Truss

A kingpost oak truss features a central, vertical post. Our King post European Oak trusses are that grand 'wow' feature of any building. The natural beauty and skilled craftsmanship in our king post oak trusses will prove a major role in creating your dream look you want. It will only be done once so it's important to do it right first time round, knowledge and craftsmanship are vital. You can design your king post trusses on our 3D builder above.

Queen Post Truss

Queen Post Truss
Queen Truss

The queen post oak truss excludes the central post found in the king post. Our queen post oak trusses are another traditional design but can come in many different layouts according to the structural engineer's requirements and also the client's. The queen oak post truss design have been used for centuries and often used when wider spans are required or to even add an additional roof room. Many people today choose a queen post oak truss when requiring another living area upstairs, the positioning off the braces allow you to create a sound structural oak truss as well as having the space in between braces to allow a walk through space in to another living area. You can design your queen post trusses on our 3D builder above.

Raised Tie Truss

Raised Tie Truss
Raised Tie Truss

The best way of describing a raised tie truss is to think of the capital letter 'A'. Raised tie (beam) trusses are essentially a king post truss but with the bottom oak beam higher up, allowing more ceiling space. They are therefore normally used where there's limited head space, or if the overall building height is restricted.

Mono Truss

Mono Truss
Mono Truss

Mono trusses are basically half oak trusses are usually used in lean to buildings and smaller side buildings and extensions. With the truss only having one principal rafter and one tie beam the design has to be slightly different by adding in extra braces or support to support the principal rafter.

Cruck Truss

Cruck Truss
Cruck Truss

Instead of straight primary rafters, the rafters of a cruck truss curve together and meet at the top, giving an elegant, sculpture-like look. Large cruck trusses produce a traditional "grand church roof" style.

Cruck trusses are making something of a comeback in house renovation and new builds for people who want solid oak trusses but aren't a fan of the straight edges found in the more popular king and queen oak trusses.

Arched Truss

Arched Truss
Arched Truss

Instead of a straight tie beam, the arched truss sees the bottom tie beam curved, raising in the centre. Arched trusses are very popular in properties with a more rustic, country feel.

Truss Delivery

Your trusses will be delivered on a lorry ready to assemble. Each piece is coded making assembly simple for you or your builder.

Because each truss is individually made we currently have a 7 - 9 weeks (from drawing sign off) lead time.

Because many of our customers already have lifting equipment on-site, our lorries do not have unloading equipment on them. You will therefore need unloading equipment available, such as a forklift or crane, or enough manpower to manually unload the components.

Oak is very heavy so please ensure you have means to safely unload from the lorry.
