Our solid oak beam range of fireplaces and mantelpieces have each been handworked and are available air dried in a variety of sizes and finishes.
Important: Please note the following before purchasing:
- If you have chosen a 'Lightly Worked' or a 'Heavily Worked' beam from the above choices, unless specified in the 'Order Notes' upon checking out, we will work the largest beam face. Please state in the order notes section if you have a specific requirement or want the beam a different way. if you are not sure of the difference between the finishes, please watch our video at the bottom of the page.
- If you are looking for a custom size beam, please order the size above what you require and specify your chosen size in the 'Order Notes' section of the checkout. We will ensure that it is planed to your specific required dimensions.
-
The cross-section sizes listed are approximate starting sizes and will reduce by up to 3/4 of an inch after being planed and sanded; So you may wish to order the next size up to allow for this. For example 6″ x 6″ starting size will reduce down to no more than approx. 5.25″ x 5.25″, 8″ x 6″ starting size will reduce down to no more than approx. 7.25″ x 5.25″ etc, the length will remain as selected.
- Refer to imperial sizes (inches and feet) for accurate lengths and cross-sections. Metric dimensions provide an approximate translation.
- Ensure that your beam is taken out of its wrapping immediately after receiving the delivery to allow it to breathe and adjust.
- We do not pre-drill beams as customers will need to ensure that fixings are secured to the wall are in the correct place.
Oak is a natural product and therefore each individual piece will be different in appearance and will vary slightly in colour and grain. Our character grade beams may well already contain knots, surface cracks, pinholes and waney edges and cracks would be expected to develop further once they acclimatise to a new environment after purchase. Although our beams are air-dried, it also is not unusual for the oak to develop further shrinkage and movement as it continues to dry and adjust to your property's temperature. If your beam is going to go above a fire, log burner, fire or intense heat, we recommend that the heat should be gradually increased over a period of a week or more if possible.
All of our oak is PEFC certified, meaning that it is sustainably sourced, and the forest management is environmentally appropriate, economically viable and socially beneficial management for present and future generations.
Depending on your choice of beam size, we can supply you with a choice of straight brackets, T-Shape Brackets or keyhole brackets; should you have a preference, please leave a note in the 'Order Notes' section of the checkout when purchasing your oak beam. If no notes have have been added we will send out straight brackets with all beam sizes apart from ones with a 2" projection out from the wall, where we will send out keyhole brackets.
See our image gallery for a representation of how the different coloured oils will look on your oak beam, bearing in mind that the grain and colour of each piece of wood is different so this is a rough guide only.

Very happy with it, fab piece of Oak and really well packaged and excellent price
Very pleased with the beam. Arrived early than stated
Lovely piece of oak but not enough oil, bought more online.
We have just recently had a wood burner installed and needed a mantel . After searching everywhere I came accross Celtic Timber . The service I received was 5 ⭐️’s . Customer service was brilliant - I ordered the mantel on the Thursday and it was received the following Wednesday . Superbly wrapped and absolutely no damage .Literally AMAZING quality . The Mantel was lightly worked and was cut specifically to my wishes . We chose a 6x8 size (6 being width) and this was very heavy . If there is one negative , I would say that the fixings supplied were not going to be strong enough ( this was over 32kg in weight !) Not a problem for my installer as they have experience with this and came prepared with extra strong bolts , my mantel wont be moving anywhere for a LONGGG time .
Oil supplied was PURE … at first I wasn't too sure about the colour but actually its perfect . Dont be alarmed by the tiny bottle , this is more than enough for a beam this size - I still have some left over ! It applied well and really brings out the beauty of the wood .
I would use this company again and definitely recommend to others . Even my installers commented on what amazing quality and how nice the wood is.
Very pleased with the results - Thank you Celtic Timber - Exceeded my expectations, I am extremely pleased .
3 out of the 5 fixtures were bent and the centre line of the beam had a split down the middle , not great considering the price
