Pre-stressed textured Concrete Lintels are manufactured using lightweight aggregate concrete which has two main benefits, it makes them easier to handle compared to other lintels and also gives them greater resistance to heat transmittance. They are generally used for load bearing over window and door openings in brickwork but can also be used for bearing under steel as a pad stone or bridging across manhole openings.

Technical
Lintels are manufactured largely by the Slip-Form Method with the following materials specification applying to them:
Concrete : Cube strength = 50N/mm² at 28 days.
Cement : Portland cement to BS 12.
Aggregates – crushed rock : Sintered P.F.A and washed sand.
Prestressing Strand: 9.3 dia. and 7.9 dia., wire strand to BS 3617, 1971.
Quality and strength are maintained by strict supervision and the use of modern machinery.

Lintels are designed and manufactured in accordance with BS EN845-2-2003 (Part 2: Lintels).
