e.g. grade 316 for ultra highly corrosive environments. A/1
with additional protective coating*, A without.
B/ Mild Steel
- Complying with BS4360. B/1 with additional protective coating.
Also paint finishes to your requirement.
C/ Structural Steel

manufacture to BS729 with a minimum coating weight of 920g/m
2 including both sides. C/1 with additional protective coating*,
D/ Galvanized Steel
- Complying with BSEN10142 1991. Lintels are manufactured
from continuously hot dipped, zinc coated low carbon steel
sheets, cold formed with a minimum coating weight of 600g/m
2 including both sides. D/1 with additional protective coating*,
Additional Protective Coating*
The additional protective coating consists
of self etch primer followed by 100 microns of black bituminous
- Lintels should be checked on delivery and only undamaged
lintels used. An end bearing of at least 150mm (Click
here for Lintray bearing) is required and lintels should
be fully bedded on brick laying mortar, ensuring that the
front and back of the lintel is level before proceeding. The
inner and outer leaves supported by the lintel must be raised
together to avoid excessive eccentricity of loading.
Blocks should continue for the full length
of the inner flange. Loads should not exceed the stated figures
with a ratio of 1:5 (outer to inner) for the SC ranges and
1:19 for the MC and HC ranges. Consult our technical department
before exceeding these loads or applying point loads. A supported
cavity wall should incorporate suitable wall ties above the
lintel to provide stability.
In Scotland, Northern Ireland and areas
of severe exposure, (as defined in BRE Digest 127) seperate
damp proof protection is required over all lintels unless
a LINTRAY™ is used.
The safe working loads of all lintels
are derived by calculations in conjunction with computer modelling
technology and tests at the University of Glamorgan in accordance
with the requirements of BS5977: Part 2: 1983.
- Quality assured to BS EN ISO 9002:
- 1994. All products comply with BS 5977:
- 1983 for corrosion, protection, workmanship
Service - We provide an expert advisory and design
service completely free of charge. Technical advice on specification,
design or installation. Structural loading calculations. Design
of special lintels in accordance with your exact requirements
including computer produced detailed dimensioned drawings.
Insulation - All cavity wall lintels are
fully insulated with close fitted, CFC free, high density
polystyrene, manufactured in accordance with BS3837; Part1:1986.
Formed to the exact profile of the lintel, throughout the
entire length of the lintel.
