Choose a lintel that extends beyond the opening on both sides, typically by at least 150mm, ensuring adequate bearing for load distribution.
Structural Support Guidance for Modern Masonry Openings
Concrete lintels provide reliable structural support above openings such as windows, doors, and passageways. This range includes prestressed and reinforced options in various lengths and section sizes, designed to carry vertical loads safely across masonry spans. Their dense concrete composition offers strength and stability, making them suitable for brickwork, blockwork, and areas where consistent load distribution is required. Many are used alongside Sand, Cement & Aggregates for bedding and finishing, creating a stable interface between the lintel and surrounding masonry.
These products are commonly incorporated into external walls, internal partitions, and extensions where straightforward installation and compatibility with standard masonry dimensions matter. Prestressed variants reduce weight while maintaining rigidity, and reinforced types support higher loads, depending on the structural requirement. When used with Brick & Block, lintels help maintain uniform courses and ensure openings remain secure over time, especially in areas exposed to weather or variations in load. Technical considerations such as allowable span, bearing length, and compliance with recognised standards guide the selection of each unit.
When paired with components such as Damp Proofing materials or placed above cavities that require ventilation channels, lintels help maintain structural safety and moisture control across different wall configurations.
Concrete Lintels FAQ's
Most lintels include internal steel reinforcement. External reinforcement is not usually required unless specified in structural plans.
Cutting is not recommended because it can expose or damage internal reinforcement. Always select the correct length from the available range.
Set the lintel on a level mortar bed with the correct bearing, ensure it is fully supported during installation, and avoid loading it until the mortar has cured.
Yes. Many lintels are designed for single-skin and cavity wall applications. Always check span capacity and compatibility with the wall design.
