Ensure strong structural support above openings with our range of Steel Lintels, ideal for brickwork, blockwork and cavity wall construction. Steel lintels are designed to carry the load of masonry above doors and windows, helping prevent cracking, sagging and long-term movement. Whether you’re working on a new build, extension or renovation, choosing the right lintel is essential for safe, professional results and reliable performance over time.
Steel lintels are commonly used for external and internal wall openings, offering a durable solution with excellent strength-to-weight performance. They’re ideal for supporting brickwork over windows, doors, garages and wider spans where structural stability is critical. With different sizes and specifications available, it’s easier to match a lintel to your wall type, cavity width and load requirements, helping ensure the opening is supported correctly.
For best results, select the correct lintel length with suitable end bearing, install level, and ensure compatibility with the wall build-up and insulation requirements. Proper installation and correct support during building helps maintain alignment and ensures the finished brickwork stays tidy and secure.
