This guide is for builders and contractors seeking a robust, standard-duty lintel solution for angled single leaf external masonry walls. It provides critical support over openings, ensuring structural integrity and compliance with essential building standards. While highly effective for its intended application, its specialized design means it is not suitable for all wall types.
Angled Single Leaf Design: Specifically engineered for angled single leaf external masonry walls, providing precise fit and structural support.
Standard Duty Load Rating: Capable of supporting loads up to 15kN, suitable for a wide range of standard building applications.
Wide Span Compatibility: Designed for use across spans ranging from 900mm to 3900mm, offering versatility for various opening sizes.
Brickwork Compatibility: Perfectly suited for 100-102mm outer leaf brickwork, ensuring seamless integration with common masonry practices.
Corrosion Protection: Features integral corrosion protection with either a galvanised finish (up to 2400mm) or a black powder-coated finish (2550mm and above) for enhanced durability.
Certified Performance: Complies with BS EN 845-2 standards, guaranteeing tested and reliable structural performance.
Specifically designed for angled single leaf external masonry walls, ensuring optimal fit and performance.
High standard duty load rating (up to 15kN) provides reliable support.
Available in a wide range of lengths to accommodate various opening spans.
Integral corrosion protection enhances longevity and reduces maintenance.
Meets BS EN 845-2 standards for assured quality and safety.
Compatible with common 100-102mm brickwork.
Specialized design means it is not suitable for non-angled or cavity wall applications.
Requires specific 150mm end bearings for stated load rating, which must be factored into design.
Different finishes (galvanised vs. powder-coated) depending on length, requiring attention during ordering and installation.

The Catnic ANG Lintel is engineered for reliable performance in its specific application: supporting openings within angled single leaf external masonry walls. Its standard duty rating of up to 15kN, achieved with correct 150mm end bearings, makes it suitable for typical residential and light commercial loads. For example, it can effectively support window or door openings in a garden wall or an external porch where a single skin of brickwork forms an angled structure.
The steel construction, coupled with either galvanised or powder-coated finishes, ensures excellent corrosion resistance, crucial for external applications exposed to varying weather conditions. Its compatibility with 100-102mm outer leaf brickwork simplifies integration into standard building practices. The lintel's design ensures efficient load transfer from the masonry above to the supporting structure, maintaining stability and preventing cracking or structural failure around openings. The performance is certified to BS EN 845-2, giving confidence in its structural capabilities.
Measure Accurately: Ensure the lintel length chosen is appropriate for the clear span of your opening, allowing for the recommended end bearings.
Provide Adequate Bearings: This lintel requires 150mm end bearings on each side to achieve its stated 15kN load rating. Insufficient bearing can compromise structural integrity.
Position Correctly: Place the lintel level and squarely over the opening within the angled single leaf external masonry wall.
Mortar Bed: Install the lintel on a fresh mortar bed, ensuring full contact across the bearing surfaces.
Support During Curing: Provide temporary propping or support beneath the lintel until the mortar has fully cured and the masonry above is stable.
Wall Type: Exclusively designed for angled single leaf external masonry walls.
Brickwork: Compatible with 100-102mm outer leaf brickwork.
Span: Suitable for clear spans between 900mm and 3900mm, with various lintel lengths available within this range.
Inspection: Regularly inspect installed lintels for any signs of damage, corrosion, or structural movement, especially after extreme weather.
Finish Protection: The galvanised finish (for lengths up to 2400mm) and black powder-coated finish (for lengths 2550mm and above) provide integral corrosion protection. Avoid scratching or damaging these coatings during handling and installation to maintain their protective properties.
Cleaning: Clean masonry around the lintel as per standard building practice, avoiding harsh chemicals that could damage the protective coating.
