FAQs

What is the purpose of the perforations on the inner flange?

The perforations provide a key for plaster, allowing for a better bond and finish.

What is the minimum end bearing required?

A minimum end bearing of 150mm on each side of the opening is required.

What cavity widths are these lintels suitable for?

These lintels are suitable for cavity widths between 95-110mm.

What type of applications are these lintels designed for?

These lintels are designed for standard load-bearing applications in cavity walls.

How do I ensure the lintel is installed correctly?

Follow standard building practices for lintel installation and ensure the lintel is level and properly supported, with the required end bearing.

Can these lintels be used in all types of buildings?

These lintels are suitable for a wide range of buildings but are specifically designed for standard load-bearing applications within the specified cavity width range.

What should I do if the lintel is damaged during transport or installation?

If the lintel is damaged, assess the extent of the damage. For minor damage, touch up the protective coating. For significant damage, consider replacing the lintel or consulting a structural engineer.

Troubleshooting

Lintel appears to be sagging or bowing after installation.

Check the end bearing to ensure it meets the minimum requirement of 150mm on each side. If the bearing is insufficient, the lintel may not be adequately supported. Check for any damage or stress on the lintel.

Difficulties in aligning the lintel during installation.

Ensure the opening is accurately measured and prepared before installing the lintel. Use appropriate shims and supports to level the lintel during the installation process.

Rust or corrosion is visible on the lintel.

Inspect the protective coating for any damage. Address any areas where the coating is compromised and apply a suitable anti-corrosion treatment or coating if necessary.
