100 x 215 Section Prestressed Concrete Lintel 600mm

R22 is a Prestressed concrete lintel which can be reversible, manufactured by Stressline . All their Prestressed lintels are designed with a concrete strength of 50N/mm2 and utilising strands to BS5896:2012 and offer a minimum of 1/2 hr fire resistance which can be increased by additional protection e.g plasterboard.

RECOMMENDATIONS FOR APPLICATIONS

The Prestressed lintel range is designed in application to support the following:

- Masonry Loads

- Uniformly distributed timber floor loads

- Uniformly distributed roof loads

- Concrete Floor Loads

- Attic Truss Loads

- Point Loads : Compound trusses : Steel beams etc..

RECOMMENDATIONS FOR INSTALLATION

• The lintel should be bedded on mortar and levelled both along the lintel and across its

width. Full bricks, blocks or padstones should be used as bearing areas. Do NOT bear lintels onto

cut blocks!

• Recommended minimum bearings are: - 100mm both ends in structural openings up to 1000mm long

- 150mm both ends in structural openings over 1000mm long

This does not discharge the installer’s responsibility to ensure that the bearing pressures of the

masonry are not exceeded. To overcome this, longer bearings may be required or additional

padstones and spreaders could be provided under the bearings of the lintel.
