Kennings carry an extensive range of both concrete and steel lintels for everyday building use.

Stressline SL200 BOX external solid wall steel lintels are easy to install and the galvanised finish means they are tough and durable boasting impressive thermal efficiency. This range of BOX lintels are designed for heavy loads on a 19:1 ratio.

Our lintels can be used for internal and external applications and are suitable for all construction methods: solid wall, timber frame or brick and block.

The SL200 BOX range of lintels are equivalent to the following lintels produced by other manufacturers:

• Catinic CN71A, Catnic CN81B
• IG BOX 200
• Birtley SBL 200

Many are held as stock items, with any special orders being something we can source and supply with very short lead times.

We can deliver from branch stock or direct to the site depending on your building project's quantities.
