If you are looking for a natural, beautiful centrepiece to your home or living room then look no further!

Celtic Timber is a market leader in the sale of oak beams. Our beams are handcrafted to make the perfect oak fireplace or oak mantelpiece.

Our range of solid oak beam fireplaces and mantelpieces have been hand worked by our skilled team and are available in a massive range of sizes.

Important please note the following before purchasing;

As oak is a natural product each piece may be different in appearance and slightly in colour. Our character beams may already contain surface cracks, knots, pin holes, & waney edges. Although air dried to the Pembrokeshire Climate, it is not unusual for the oak to develop further shrinkage, movement, splits and cracks as it acclimatises to your property’s temperature. We recommend that if the beams are going above a log burner, fire or any intense heat, that the heat should be gradually increased over a period of a week or more if possible.

Please ensure that beams are taken out of their wrapping immediately after delivery receipt to allow them to breathe and acclimatise.

Depending on your choice of beam size, we will send you 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 you are looking for a bespoke size beam, please order the size above what you require and specify your chosen size in the ‘Order Notes’ section of the checkout.

Planed and Sanded for the perfect finish.
