When a beam needs to perform structurally and look outstanding, the choice of timber is critical. At Oakfield Beams & Framing Ltd, we specialise in supplying high-quality air dried structural oak beams across Sussex, Surrey, Kent and the rest of the UK. Ideal for extensions, barn conversions, refurbishments, oak-framed features and open-plan renovations, our air dried oak delivers the perfect balance of strength, stability and natural beauty.
What Are Air Dried Structural Oak Beams?
Air dried structural oak beams are premium oak sections that have been carefully seasoned over time in controlled conditions to reduce moisture content before use. Unlike green oak, which is used soon after sawing, our air dried oak is naturally seasoned for several years, resulting in a more stable and predictable timber with lower moisture levels.
This makes air dried oak the preferred choice for visible structural applications where minimal movement, clean lines and long-term performance are essential. Whether you need exposed oak beams in a kitchen, vaulted ceiling, fireplace opening, porch or garden room, air dried oak provides authentic character with greater dimensional stability.
Why Choose Air Dried Oak Beams from Oakfield Beams?

Homeowners and builders across the South East choose our air dried structural oak beams when they want real oak that performs structurally while enhancing the finished aesthetic of the building from day one.

Structural Grading, Sizing & Bespoke Service
At Oakfield Beams & Framing Ltd, we never supply structural oak on appearance alone. Every beam is selected and graded to meet the specific load, span and building requirements of your project.
We work closely with engineers, architects and builders to ensure the correct:
Strength grade (e.g. THA, THB, D40, D30)
Section size and length
Moisture content
Machining, morticing, chamfering and finishing
All beams can be supplied to your exact drawings with precision end cuts, housings and jointing details.
Natural Beauty with Realistic Expectations
Oak is a natural material. Our air dried structural oak beams feature beautiful medullary rays, colour variation, knots and occasional surface checking — all part of genuine English oak’s charm. We can supply beams in sawn, planed, or hand-finished appearances depending on your project style.
