Please take note of the following before purchasing:
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.
Please 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.
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.
See our image gallery for a representation of how the different coloured oils will look on your oak beam. Please bear in mind that the grain and colour of each piece of wood is different so this is a rough guide only.
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.
