The tables on these pages provide the specifier with a quick
guide to IG's range of steel lintels.
Lintels are identified by type, loading characteristics and cavity
widths with reference to the appropriate page for full details.
Before consulting tabular information, specifiers are advised
to read the Technical Information pages 33-35 to verify
that properties and installation of IG steel lintels meet the
requirements of intended usage.
For standard duty loading conditions only

Designed to provide a quick and safe method of spanning small openings (up to 1000mm) in internal walls, IG internal linteis are both economical and easy to store, carry and use.
When a minimum height of 152mm of brick/blockwork with well-filled joints of cemed mortar is built wsrthe lintel, the construction will be load-bearing for normal domestic building purpa!m after curing. Ths loading capacity Otthe lintel can be increasod by increasing the high! of the walling built across It.

TECHNICAL INFORMATION
STRUCTURAL PERFORMANCE L The loading tables in this brochure are the result of testing at the group’s premises under the supervision and direction of the British Board of Agrbment.
All tests were carried out in accordance with BS 5977 Part 2 1983 and BS EN 846-9:2000 and relate to the strength and torsional stiffness of lintels to sustain total uniformly distributed loads.
The loading tables shown for the L1 (where noted), Ll/E, L5 and L11 lintels are the results of testing in accordance with BS 5977 Part 2 1983 and BS EN 846-9:2000, taking into account composite assistance from the surrounding masonry, this masonry should be of good quality (in accordance with BS 5628).
A lintel should not exceed a maximum vertical or horizontal deflection of 1/325 x the effective span, when subject to the safe working load.
Note:
load ralio 1 - applies to loads with an inner to outer leaf ratio of between 1 :1 and 3 :1. This ratio is normally applicable to lintels that support:
a. masonry b. masonry and timber floors
load ratio 2 - applies to loads with an inner to outer leaf ratio of between 4 :1 and 19:l. This ratio is normally applicable to lintels supporting: a. constructions with concrete floors b. eaves applications
FKE TEST 1
The L1 profile has been subjected to two fire tests by: a. The fire research station, Boreham Wood. b. The Warrington Fire Research Station. In both cases one hour fire rating was achieved with the load successfully supported 48 hours later. Further details available on request.
The service life of lintels will be equal to the life expectancy of the building when installed with a flexible DPC and within
the humidity and condensation conditions normally experienced in habitable buildings.
Lintels conform to the requirements of BS EN 845-2:2003 for corrosion protection, workmanship and materials.
IG lintels are rated by the Housing Association Property Mutual as satisfying the ‘35 years to first maintenance’ durability rating, laid down in the ‘HAPM Component Life Manual’.
Galvanised linlels - lintels are fabricated from galvanised steel to BS EN 10142 1991 Specification for continually hot dip zinc coated low carbon steel sheet and strip for cold forming: Technical advisory conditions, grade Fe PO1 G, with a coating type 2600 giving a minimum coating weight (triple spot test) of 600g/m2; including both sides but with a minimum yield stress of 250 N/mm2.
Stainless steel - with the exception of the L6 and internal type lintels, all IG lintels can be manufactured from stainless steel.
Stainless steel lintels and expanded metal lathing are formed from Austenitic Chromium Nickel Steel to BS EN 10088-2 1.4301 (304S15) and require no additional corrosion treatment. Higher grades of stainless steel can be supplied on request - BS EN 10088-2 1.4401 (316S31).
For the lintels to perform to the quoted loading figures and to meet the durability expectations included in this brochure, the following information MUST be adhered to:

Lintels damaged in transit should not be used.
Check the correct lintel is being installed.
All bearing areas should be prepared using full bricks/blocks or padstones.
Lintels should be installed with a minimum 150mm end bearing at both ends, be fully bedded on bricklaying mortar and levelled both longitudinally and horizontally. When limited end bearings are unavoidable, check with IG technical office for suitability.
Open back lintels should be filled with masonry in accordance with BS 5977 and a full block built in through the end bearing and allowed to cure before continuing building.
The inner and outer leaves supported by the lintel should be raised together to avoid excessive eccentricity of

7. When installing concrete floor units or other heavy components, care should be taken to avoid shock loading. Temporary support in the form of props is advisable if there is a limited amount of masonry to the outer leaf. Pre-cast floor units should be laid on a mortar bed to avoid load concentrations at high points in the masonry. Floor units should not be dragged into position.
8. Point loads should not be applied directly to lintel flanges. Lintels should have a minimum of 150mm

GABLE ABUTMENT SYSTEM
When a stepped or staggered gable abutment is formed the status of the external skin below the roof line changes to that of an internal skin. Accordingly, every gable abutment must be constructed so as to prevent dampness and rainwater from penetrating below the abutting roof line.
The IG Gable Abutment Cavity Tray forms a stepped cavity dpc which is incorporated into the building during bricklaying. The completed structure is ready to receive roof lead flashing in the conventional way.
THE 10 CAVITY TRAY - TYPE GA
Manufactured from polypropylene, the IG Gable Abutment Cavity Tray is available in three sizes to suit all roof pitches up to 60". It is suitable for use in all brick, block and timber- framed constructions, the large bridging piece catering for cavity widths from 50mm to 100mm.
Supplied flat, the pre-creased trays allow for easy on-site folding to the required shape - catchment, left and right hand or ridge tray. A locating lip facilitates the accurate placement of trays during bricklaying.
CALCULATING QUANTITIES
The single-element system makes the calculation of quantities very simple. Whether you are building with bricks or blocks the rule is the same: you require one cavity tray per course per slope. On a double slope roof this calculation will give you an extra tray that can be used to lengthen the ridge tray if required.
SIZES AND ROOF PITCHES
The IG Gable Abutment Cavity Tray is available in three sizes as detailed below. Trays are supplied in shrink-wrapped flat packs in the quantities indicated or as single items.

INTERNAVEXTERNAL CORNERS
Flat-packed foldable corners complete the IG Gable Abutment Cavity Tray System. Both internal (GAIC) and external (GAEC) corner trays comprise factory-jointed two-piece assemblies
that are folded on site to form right-angled corners. The trays are pre-creased and incorporate adjustment for 50mm, 75mm or 100mm cavity widths and incorporate mastic sealant strips for overlapping areas.
REFURBISHMENT SYSTEM
The IG Refurbishment Cavity Trays System has been specifically developed to facilitate both the insertion of a new tray into an existing wall and the repair or alteration of an existing damp proof course.
WHERE TO USE
Where a new lean-to extension meets an existing building, the original external wall becomes an internal partition below the roof line and must be protected from dampness and the penetration or rainwater. Similarly, when a flat roof is resurfaced with added insulation, or is reconstructed as an inverted roof with top paving, the roof level may be raised and thus require the skirting and its corresponding damp proof course to be lifted.
In addition, existing cavity trays which have been poorly constructed or have rotted allowing water to leak through must be replaced.
THE IG CAVITY TRAY - TYPE RFT
Available off-the-shelf in flat-packs, the IG Refurbishment Tray combines ease of handling, transportation and use with complete effectiveness. It meets all current Building Regulations and NHBC requirements. Manufactured from polypropylene, the IG Refurbishment Tray is 620mm wide by 280mm deep and is suitable for use in all brick, block and timber-framed constructions. The large bridging piece caters for cavity widths from 50mm to 100mm.
Supplied flat, the pre-creased trays allow for easy on-site folding to the required shape including forming left and right hand end stops. A locating lip facilitates accurate placement during installation and the mastic sealant strip (protected by release paper) ensures easy and watertight overlap jointing.
SPECIFYING
When specifying, the following wording is recommended: "Provide IG Refurbishment Cavity Tray System from IG Limited, Cwmbran, Gwent NP44 1XY (01633 486486) to be installed as manufacturer's instructions. Trays to be folded, as instructions on tray, to form left and right hand stop ends".
