FAQs

What is the recommended end bearing for the CG90/100 lintel?

A minimum of 150mm end bearing is recommended on both sides for optimal load distribution and stability.

Can I use this lintel for heavy-duty applications?

No, this lintel is designed for standard duty applications only. It is not suitable for heavy loads.

What is the cavity width that this lintel is designed for?

The CG90/100 lintel is designed for cavity walls with a width of 90–105mm.

How do I ensure proper alignment during installation?

Make sure the lintel is level and correctly positioned within the cavity. Check for any obstructions preventing proper alignment. Use shims if necessary.

What kind of protection does the lintel have against moisture?

The lintel incorporates a built-in DPC (Damp Proof Course) to prevent moisture penetration and protect against damp.

What material is the lintel made of?

The lintel is made of galvanised steel for corrosion resistance.

Are there different lengths available?

Yes, lengths range from 750mm to 3600mm to accommodate various opening sizes.

What is the purpose of the integral plaster key?

The integral plaster key enhances plaster adhesion, resulting in a robust and tidy finish.

Troubleshooting

Lintel sagging or bending after installation.

Check if the correct lintel length was selected for the opening size and load. Verify that the end bearings are adequate. Ensure proper support from below.

Difficulty in aligning the inner and outer leaves.

Ensure the lintel is level and correctly positioned within the cavity. Check for any obstructions preventing proper alignment. Use shims if necessary.

Premature rust or corrosion.

Check for damage to the galvanised coating. Ensure proper storage before installation. If the damage is significant, replace the lintel.

Cracks appearing in the surrounding brickwork.

Verify that the lintel is correctly installed. Check the load-bearing capacity and ensure that it is not overloaded. Inspect the brickwork for any other underlying issues.

Setup, Compatibility & Care

Setup

Measurement: Accurately measure the opening width to determine the correct lintel length. Consider the necessary end bearings (minimum 150mm on each side).
Positioning: Place the lintel into the cavity, ensuring it sits on a level base and is properly aligned with the inner and outer leaves.
End Bearings: Ensure a minimum of 150mm end bearing on both sides for optimal load distribution.
Simultaneous Leaf Elevation: The design allows for both inner and outer leaves to be raised at the same time, simplifying installation.
Blockwork: Before installing flooring or roof elements, lay at least one course of blockwork above the lintel for enhanced structural performance.

Compatibility

Cavity Width: Designed for 90–105mm cavity walls.
Leaf Thickness: Supports inner leaves (100–115mm) and outer leaves (100–102mm).
Load: Suitable for standard duty applications only. Confirm load-bearing requirements.

Care

Handling: Handle with care to avoid damage to the galvanised coating during installation.
Storage: Store the lintels in a dry place to prevent premature corrosion before installation.
Inspection: Regularly inspect the lintel for any signs of damage or corrosion, especially in harsh environments.
