Lintels provide essential structural support above windows, doors and other openings, ensuring that loads are safely transferred to surrounding masonry. Whether you’re working on a new build, extension or renovation, quality lintels are critical for long-term stability, compliance and performance in all building types.
Concrete Lintels for Traditional, Durable Structural Support
Concrete lintels offer reliable strength and excellent fire resistance, making them ideal for a wide range of domestic and commercial applications. Suitable for internal and external walls, concrete lintels provide consistent load-bearing performance, durability in harsh weather conditions and compatibility with brickwork and blockwork construction.
Steel Lintels for Lightweight, High-Strength Load Distribution
Steel lintels are engineered for superior strength-to-weight performance, allowing them to span wider openings while supporting significant structural loads. Galvanised for corrosion resistance, steel lintels are commonly used above doors, windows, bi-fold openings and wide structural gaps, offering excellent thermal efficiency and long-term durability.
Reliable Load-Bearing Solutions for All Build Types
Whether you choose concrete or steel, lintels ensure safe load transfer and structural integrity across both cavity and solid wall constructions. They are essential components for masonry openings, roof support and modern architectural designs.
