Steel Lintels Installation

Lintel Tip One

Check your Lintel to ensure you have received the correct Specification and there is no Damage to your Lintel.

Any Damage to your Lintel may affect its performance.

Reach out to your Supplier. 

A Reputable Lintel Supplier will be happy to discuss your concerns and rectify any issues if your Lintel has been unexpectedly damaged in Transit to you.

Lintel Tip Two

Your Steel Lintels should be bed on a full layer of Bricklaying Mortar and, as a General Rule, have a minimum end bearing of at least 150mm at each end.

Lintel Tip Three

Make Sure your Lintel is Level.

When installing Steel Lintels, ensure it is level along the Lintel and Across the Lintel.

Lintel Tip Four

When Laying your Bricks, ensure you bring them up simultaneously.

Raise the Inner and Outer Leaves simultaneously to a maximum height difference of 225mm.

This method will avoid excessive eccentricity and rotation.

Tip Five

Allow the Mortar to Cure before Load Bearing.

You may be able to use Temporary Propping beneath the Lintel if you cannot wait.

Check with your Structural Engineer

Tip Six

It is recommended to install a Lintel with a damp proof course (dpc) or Cavity Tray in a Cavity Wall.

Installing a damp proof course dpc is Good Practice, but it is also an NHBC Requirement and will reduce the risk of Lintel Failure in the Future.

Some Lintels will have a Built-in Dpc, such as Catnic Lintels. Check with your Supplier. 

Tip Seven

Avoid Shock Loading

If you are Installing Concrete floor units or heavy components, place these carefully and do not Drag heavy components or Concrete Floor Units across the Lintel.

Tip Nine

Project external Lintel flanges slightly beyond the window frame or Doors and ensure they are adequately protected with flexible mastic.

Tip Ten

Lintel soffit cladding can be used when the underside of the Steel Lintel is exposed.
