FAQs

What type of wall is the Catnic ANG Lintel ANG2400 designed for?

It is specifically designed for angled openings within single-leaf external masonry walls, accommodating 100-102mm brickwork.

What is the maximum span this ANG2400 lintel can support?

This ANG2400 model is suitable for clear spans up to 2400mm. The Catnic ANG range supports spans from 900mm to 3900mm.

How much weight can the Catnic ANG Lintel ANG2400 support?

It is rated for loads up to 15kN (kiloNewtons). This load capacity is achieved when the lintel is installed with a minimum of 150mm end bearing on solid masonry at each end.

Does this lintel require any special weather protection?

No, the ANG2400 lintel comes with an integral galvanised finish, providing robust corrosion protection for external applications. Longer lintels (2550mm+) feature a black powder-coated finish for enhanced weather resistance.

What standards does this lintel meet?

The Catnic ANG Lintel ANG2400 is manufactured by Catnic and meets the performance and quality standards of BS EN 845-2, ensuring its suitability for structural applications.

What is meant by 'end bearing' and why is it important?

End bearing refers to the length of the lintel that rests on the supporting masonry at each end of the opening. A minimum of 150mm end bearing is crucial for the Catnic ANG Lintel to achieve its stated load capacity of 15kN and ensure proper structural support.

Troubleshooting

The lintel appears to be deflecting or sagging after load application.

Immediately cease further loading. Verify that the lintel was installed with the required 150mm end bearings on solid masonry at both ends. Insufficient bearing is a common cause of premature deflection. Also, ensure the correct lintel length was selected for the span and that it is not overloaded beyond its 15kN rating.

Signs of rust or corrosion are appearing on the lintel.

Although galvanised for corrosion protection, inspect if the coating was damaged during transit or installation. Deep scratches can expose the bare steel. If visible, clean the area thoroughly and apply a galvanised repair spray or paint to prevent further corrosion. Ensure the lintel is not in continuous contact with corrosive agents.

The lintel does not fit flush with the 100-102mm brickwork.

Confirm that the brickwork being used is indeed within the 100-102mm specification. If the brickwork is wider or narrower, the lintel may not integrate correctly, potentially affecting stability. Re-evaluate masonry dimensions or consider alternative solutions such as packing or a different lintel model if appropriate for the project.

Pros and Cons

Pros

  • Durable steel construction ensures long-term structural integrity.
  • Integral galvanised corrosion protection for enhanced durability.
  • Specifically designed for angled single-leaf masonry, offering a tailored solution.
  • High load-bearing capacity suitable for demanding applications.
  • Complies with BS EN 845-2 standards, guaranteeing quality and performance.

Cons

  • Specific application limits its use to angled single-leaf external masonry walls.
  • Load capacity relies heavily on correct installation with 150mm end bearings.
  • Not suitable for brickwork outside the 100-102mm range.
  • Heavier than some alternative materials, requiring careful handling.

Setup, Compatibility & Care

Proper installation, compatibility checks, and minimal care are vital for the optimal performance and longevity of your Catnic ANG Lintel.

Setup Instructions

  1. Preparation: Ensure the masonry surfaces where the lintel will rest are level and clean.
  2. Positioning: Carefully lift and position the lintel above the opening, ensuring it is correctly oriented for an angled single-leaf external masonry wall. The lintel typically has an orientation specific to its design; refer to any manufacturer markings.
  3. End Bearings: Crucially, ensure a minimum of 150mm end bearing at each end of the lintel onto solid masonry. This is paramount for achieving the stated 15kN load capacity. If the bearing is less than 150mm, the lintel's load-carrying ability will be compromised.
  4. Mortar Bed: Lay a full bed of mortar on the supporting masonry before placing the lintel to ensure even load distribution and secure seating.
  5. Leveling: Check that the lintel is perfectly level (unless specific design requires a slight fall for drainage, which is generally not the case for structural lintels) before the mortar sets.
  6. Curing: Allow the mortar to cure fully before applying significant loads or continuing with the above masonry work. Follow standard masonry curing times.

Compatibility

  • Wall Type: Designed exclusively for single-leaf external masonry walls with angled openings.
  • Brickwork: Compatible with 100-102mm brickwork. Using it with different brickwork widths may require additional packing or custom solutions, potentially affecting performance.
  • Spans: This ANG2400 model is for spans up to 2400mm. Always select a lintel that provides at least 150mm bearing length beyond the opening on each side.

Care & Maintenance

The Catnic ANG Lintel ANG2400 features integral corrosion protection through its galvanised finish, meaning it requires minimal ongoing maintenance once installed correctly.

  • During Installation: Avoid damaging the galvanised coating. Any deep scratches or abrasions should be touched up with a suitable galvanised repair paint to prevent localized corrosion.
  • Post-Installation: No routine maintenance is typically required. Periodically inspect exposed areas (if any) for signs of damage or unusual wear, although the lintel is largely concealed within the masonry.
  • Cleaning: If exposed, clean any dirt or debris with mild soap and water, avoiding abrasive cleaners that could harm the finish.
