Catnic T shaped lintel built into external solid wall

What are inverted T lintels?

  • Lintels
  • Guide

Inverted T lintels are a type of steel lintel suitable for external solid wall applications. They provide support over structural openings and are designed for use in walls that are 200 to 215mm thick, accounting for a double thickness of brick or concrete block.

Being designed for external solid walls where thermal insulation is positioned on the external or internal face of the wall, integral insulation is not part of the lintel design.

How are inverted T lintels installed?

The lintels comprise a base plate designed to suit the thickness of the solid wall thickness, with a perpendicular plate in the centre for rigidity. Masonry is built up either side of the central plate to continue the solid wall construction over the structural opening.

Generally speaking, inverted T lintels are suited to standard loading conditions. For external solid walls featuring heavy or extra heavy duty loading conditions, a suitable ‘box with toe’ lintel should be used instead.
