About Our Lintels Range

A structurally sound lintel is essential for any masonry opening — whether for windows, doors or larger spans. At Burnt Oak Timber we offer a comprehensive range of lintels designed for durability, performance and ease of installation. From robust concrete lintels and steel-reinforced options to decorative keystone lintels, our collection has been curated to meet building regulations and site demands. Our online “Lintels” section lists categories such as Concrete Lintels, Cavity Lintels, Leaf Lintels and Box Lintels.

With support drawings, span charts and specification details, the range covers domestic extensions, commercial builds and refurbishment work alike.

Choosing the Right Lintel for Your Project

Selecting the right type of lintel beam begins with understanding the loads, span and wall type you’re working with. For heavy masonry above wide openings, a steel lintel may be the most appropriate choice, offering high strength and load capacity. For standard brick or blockwork openings, a pre-cast concrete lintel is an efficient and cost-effective solution.

If the wall includes a cavity or requires a decorative finish, a keystone lintel or architectural style lintel may be appropriate — combining structural performance with aesthetic detail.

For typical window openings or smaller spans, a standard window lintel is sufficient. A cement lintel may refer to a reinforced concrete product cast on site or factory-produced. It’s important to check the span rating, bearing length and whether the lintel is suitable for load or non-load bearing applications.

At Burnt Oak Timber our team is ready to help you assess the correct product specification — whether you need a steel lintel for a large structural opening or a smaller pre-cast lintel for a domestic renovation.

Installation & Application Tips

  • Always check the span rating and bearing lengths before selecting a lintel.
  • Ensure proper masonry support and packers at each end to avoid settlement.
  • For steel lintel installation: protect exposed metal from corrosion (e.g., priming or sleeving).
  • For concrete lintels, verify if it’s appropriate for load bearing or just for decorative openings.
  • When installing keystone lintels or architectural styled lintels, ensure they align with adjoining brick or block coursing for aesthetic consistency.
  • Ensure suitable damp proof course crossover or cavity bridging if needed — lintels cannot act as DPCs unless specifically designed.
  • For repairs or replacements (eg. upgrading a window lintel), check for any movement or crack patterns and remedy underlying causes before installing the new lintel.
