LINTELS WITH THE DURAGALULTRA ADVANTAGEAustralian Tube Mills lintels are high strength inline coated lintels with the innovative DuraGalUltra hot-dip zinc aluminium coating, providing a smooth surface with a uniform coating thickness, purpose designed to perform in masonry construction applications.

NOTE

*Zinc aluminium coating classes are not currently referenced in AS/NZS 4791, hot-dip galvanized (zinc) coatings on ferrous open sections applied by an in-line process.

DURAGALULTRA TESTING

Laboratory and field testing has demonstrated that the DuraGalUltra coating significantly exceeds the durability of a zinc coating with an equivalent mass in a range of different environments.

Based on these tests DuraGalUltra achieves three times the durability of regular zinc coatings of equivalent mass, in moderate and severe environments over extended exposure periods.

The comparative durability performance is enhanced significantly on sheltered and unwashed surfaces commonly found in lintel applications.

The Australian Tube Mills lintel range of products have a 250g/m2 minimum average coating mass of DuraGalUltra. At three times the performance of regular zinc coatings, this equates to an equivalent service life expectancy of a 750g/m2 zinc coating.

STRUCTURAL INTEGRITY

The structural integrity of Australian Tube Mills lintels is assured to meet the requirement of Australian Standards.

The unique patented manufacturing process enhances the strength of the base steel to create a finished minimum yield strength of 400MPa for 8mm sections and 450 MPa for 6mm sections, offering superior strength to weight ratio compared to traditional hot rolled sections.

Because lintels with a DuraGalUltra coating complies with the R3 durability classification requirements for built in components, you can be confident that with the correct installation and correct exclusion zones, you will be safely guarded against brickwork cracking through expansion of corroded products.

Australian Tube Mill’s lintels offer protection, durability and peace of mind with the full backing of Australian Tube Mills technical support.

NOTES

These tables are based on calculations in accordance with the relevant Australian Loading Codes, the Cold Formed Steel Structures Code (AS/NZS 4600), and extensive in-house testing and additional structural performance testing conducted at The University of Sydney and The University of Newcastle.

1 Lintels are subjected to dead loads and live loads in accordance with AS/NZS 1170.1.

2 Designs are valid for clay brickwork up to 110mm thick, bricks 75mm high with a 10mm mortar bed.

3 The density of the brickwork is 1950kg/m3.

4 Angle lintels are designed as simply supported single spans between supporting surfaces.

5 Maximum spacing of the roof trusses or rafter is 600mm.

6 It is assumed that the lintels are fully restrained by the presence of mortar between the vertical leg of the lintel and the brickwork, and will not be subjected to twisting.

7 No composite action between the lintel and brickwork is assumed.

8 The lintels are designed to support loads from domestic construction only.

9 The values published in the tables are based on the least load that will cause the lintel to deflect an amount equal to its span/500, the lintel to reach its shear design capacity or its moment design capacity.

10 Lintels must be propped during construction.

11 The design does not include lintels supporting point loads of any sort, such as girder trusses and strutting beams.

12 The lintels must be installed with a 100mm bearing length for clear spans less than 1 metre and 150mm bearing length for clear spans greater than 1 metre.

13 The space between the vertical leg of the lintel and the brickwork must be packed with mortar.

14 In the case where an unequal angle is used, the longest leg of the lintel must be oriented vertically.

15 It is recommended that you should take professional advice to support your selection from these tables.

LINTEL INSTALLATION

DuraGalUltra lintels are supplied with the cut ends protected with a zinc rich polyurethane primer as detailed in TS100. This primer complies with AS/NZS 3750.9: 2009, Paints for steel structures Part 9: Organic zinc-rich primer, type 1 — single pack primer.

Care should be taken during transport and handling to avoid damaging cut end protection prior to installation. Should the coating be damaged or if additional processing of the lintel is required, it may be repaired by applying Jotun Galvanite zinc rich polyurethane primer, or equivalent, to a 100 μm dry film thickness.

Prior to reinstating the coating, any surface contamination including dirt, oil or corrosion products should be removed by an appropriate method. Observe normal good painting practice with respect to weather and apply strictly in accordance with the paint manufacturer’s recommendations.

CUT END PROTECTION AND HANDLING GUIDELINES

Internal corner radii of lintels are equal to or less than, equivalent hot rolled structural angles.

IMPROVED CORROSION RESISTANCE • GREATER STRENGTH • CONVENIENCE

The DuraGalUltra coating technology applies a hot-dip zinc aluminium coating using our innovative application process pioneered in Australia by Australian Tube Mills. Our specialised application process and quality control procedures detailed in TS100 ensures that DuraGalUltra coated lintels continue to be manufactured and inspected to the standards required by AS/NZS 4791:2006 — Hot-dip galvanized (zinc) coatings on ferrous open sections, applied by an in-line process.

Lintels with DuraGalUltra comply with the AS3700-2001 R3 durability classification requirements for built-in components, by meeting the performance requirements, when tested in accordance with Appendix B of AS/NZS 2699.3:2002 — Built-in components for masonry construction Part 3: Lintels and shelf angles (durability requirements).

The Building Code of Australia recognises AS3700-2001 as an acceptable construction manual, the R3 classification of Australian Tube Mills lintels ensures compliance with the Building Code, when used in accordance with Table 3.

DURAGALULTRA TECHNICAL INFORMATION

11

Certification of Australian Tube Mills lintels is simple, as the R3 rating is clearly line marked on every length, in a position visible after installation, as required by AS/NZS 2699.3:2002 Section 4, for easy inspection and peace of mind.

NOTES

1 The distance specified are from the mean high-water mark.

2 The actual distances required from a corrosion source to provide the required performance will depend upon many factors such as prevailing winds, weather shielding exist (ie by trees and adjacent buildings), the topography of the surrounding area, and exposure to rain. In any building application, the specific micro climatic conditions must always be considered and taken into account.
