FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
Most orders arrive within 3-4 days, the maximum is 7 days. Please get in touch before you order if you need a specifc delivery date.
Delivery charges vary by postcode. To find out the delivery charge, add the item(s) you require to your basket and select CALCULATE SHIPPING at the bottom of the page.
Some orders are delivered on our own vehicles based in Leicestershire and Cheshire. We also use carriers including Yodel and Tuffnells. For some sizes and locations we use regional distributors.

Birtley Medium Duty Cavity Wall Lintel 100mm CB90HD
The Birtley CB90HD lintel is hot-dip galvanised after fabrication, providing up to 50% more zinc protection than other coatings. This process ensures every surface is thoroughly coated, leaving no weak spots and significantly extending the lintel's lifespan. Whether in harsh weather or high-moisture environments, this lintel remains corrosion-free and reliable.
The Supergalv coating further enhances the lintel's durability, offering superior protection against rust and wear. This makes the CB90HD a cost-effective, long-term solution for cavity wall constructions, reducing maintenance needs and ensuring structural integrity.
Optimised for Medium-Duty Cavity Walls
Designed for cavities between 90-105mm, the Birtley CB90HD lintel features a 100mm outer and inner leaf, making it perfect for medium-duty applications. Its robust construction ensures it can handle the demands of residential and commercial projects with ease.
Enhanced Thermal Performance
The absence of a baseplate and factory-fitted insulation reduces thermal bridging, improving the lintel's energy efficiency. For bespoke thermal bridging assessments, Birtley's in-house team of accredited thermal modelers is available to provide tailored solutions.
Compliance and Safety
The Birtley CB90HD lintel complies with BS EN845-2:2013+A1:2016 and boasts a 60-minute fire rating when used with a two-coat plaster finish. This ensures it meets rigorous safety and structural standards, providing peace of mind for builders and architects.
Customisable Options for Specific Needs
The Birtley CB90HD lintel offers flexibility with alternative material options, including Ultragalv coating (150µm) and stainless steel 1.4301 (304). Outer leaf options such as reduced length flange (RFF), no rainwater drip (ND), and render mesh (MF) are also available, allowing you to tailor the lintel to your project's requirements.
