1 Non-compliant products are the focus of an industry campaign by the HIA Are you at risk? Can you be confident that your products comply when challenged by your builders?

2 Bracing and tie down product compliance for use in residential construction

3 Non-compliant building products in the residential sector In March 2012, the HIA conducted the third of it s Building Better Cities Summits. The focus of this summit was - non compliant building products in the residential sector.

4 Non-compliant building products in the residential sector FOR IMMEDIATE RELEASE 29 March 2012 Non-Compliant Products to be the Focus of Industry Campaign The Housing Industry Association has signalled that it will spearhead a campaign to address the problem of non-compliant building products in the residential sector. The extent of the problem was highlighted by presenters and delegates at the HIA Building Products: a compliance free zone? summit this week in Melbourne. The problem of non-genuine and non-tested building materials and components making their way into in residential building is growing, said HIA Managing Director Shane Goodwin. Our view is that regardless of where something is manufactured, it should meet Australian standards. With more and more products being manufactured offshore, and increased access to these products by individuals, the need to focus on compliance has never been greater. A key concern is that the evolution of compliance and enforcement in Australia has not kept pace with changes to our economy and how or where products are manufactured or sourced. It was clear from the debate at this week s summit that there are products being used in Australia that are not fit for their intended purpose. This can have consequences such as subsequent repair costs, damage to the reputation of the building industry and potentially threats to human health and safety. Our message is that it s just not worth the risk of using inferior materials and components. The summit also identified the problem that inconsistent compliance regimes led to an uneven playing field between manufacturers that comply with standards and those that do not. Manufacturers who do the right thing are being disadvantaged against those that neither invest in producing products that meet Australian standards nor programs to demonstrate compliance. A central plank of the HIA response to the problem of non-complying building products will be the development of options for an industry led product registration scheme. To be a success, a scheme will need the buy-in of government as well as industry, so it will require an extensive consultation process. But the extent of the problem means that we can t afford to ignore it. However, it is equally important that we strike the right balance between ensuring compliance and not creating additional red tape, said Mr Goodwin. In addition to exploring a product compliance register, HIA has undertaken to: Establish an evidentiary basis of the extent of the problem; Work with the Australian Building Codes Board (ABCB) in a review of the existing Codemark and Watermark certification schemes; Work collaboratively with existing credible industry based compliance programs to ensure their ongoing success; Develop an industry education and information program to increase the understanding amongst builders, contractors and suppliers about the importance of compliance; and, Continue to support buildings standards that include Deemed to Satisfy solutions and press for the modernisation of the housing provisions in the Building Code of Australia (BCA).

Areas of concern include but are not limited to strapping, bracing and tie down fixtures, concrete and reinforcing, structural grade timber and LVL, structural steel, steel framing, windows and glazed doors, balustrading, roofing and wall cladding and masonry materials.

5 Message for suppliers to the building industry

6 Message for suppliers to the building industry Pryda has identified (via independent and internal testing) that at times some competitors are supplying strap, bracing and timber connector products that fail to comply with the relevant Australian Standards including AS1684 part 2 and Residential Timber Framed Construction. It is Pryda s intention to participate in training and marketing campaigns with representatives of building approval bodies such as the Australian Institute of Building Surveyors (AIBS) and industry associations such as the Housing industry Association (HIA) to raise the awareness of non-compliance. We expect this initiative, in conjunction with the campaign launched by the HIA, will assist building practitioners in selecting compliant products and building surveyors to assess whether buildings comply with building regulations. The standards which are referenced by the Building Code of Australia are AS , AS and AS Products which meet the requirements of these standards are deemed to comply with the requirements of the Building Code of Australia. To be compliant, a product must meet these standards or prove performance to otherwise comply with the Building Code of Australia.

7 The Australian Standard To comply with the standard, metal straps (eg: Strap Braces, Stud Ties etc), framing anchors (eg: Multigrips, Triplegrips, Joist Hangers etc) and structural connectors for tying or bracing the structural elements of a building together must meet a minimum requirement of steel strength (structural grade steel) and corrosion resistance (zinc coating thickness). Bracing must also have a minimum net sectional area.

8 Minimum dimension for bracing products to achieve the performance requirements of the standards Metal angle wall brace must have a minimum nominal section of 18x16x1.2mm. Wall braces with this minimum dimension must be used in opposing directions within one wall to achieve the required performance of 0.8kN/m 8 Ref: Table 8.18 type (a) AS , AS Ref: Table 8.3 type (a) AS

9 Bracing units using metal angle brace To achieve bracing units with a higher capacity, eg. 1.5kN/m. Metal angle brace with a minimum nominal section of 20x18 x1.2mm may be used. Note: Stud ties or equivalent are also required. Ref: Table 8.18 type (c) AS , AS Ref: Table 8.3 type (c) AS

10 Bracing units using strap brace and tensioners Bracing units to achieve 1.5kN/m performance can also be built using Strap Brace and Tensioners. The minimum thickness of strap must be no less than 0.8mm and have a net sectional area of not less than 15mm 2. eg. 30x0.8mm Strap Brace with 6mm hole punched for the fitting of a tensioner would achieve this section. Ref: Table 8.18 type (b) AS , AS Ref: Table 8.3 type (b) AS

11 Bracing units using strap brace and tensioners Bracing units with a performance of 3.0kN/m can be built using Strap Brace and Tensioners with a net sectional area of 21mm 2 30x0.8mm Strap Brace with a 6mm hole punched to accommodate the tensioner would not comply 30x1.0mm Strap Brace should be used. Note: Stud Ties or equivalent should also be used. Ref: Table 8.18 type (d) AS , AS Ref: Table 8.3 type (d) AS

For walls higher than 2.7 m, reduce the bracing unit s capacity in inverse proportion to the wall height, eg: for 3.6 m walls, take 2.7/3.6 = 0.75 times the capacity for 2.7 m height. CONSTRUCTION & DESIGN DETAILS Pryda s recommendations for materials, installation and design loads are given in the following topics. Materials Multi-purpose metal connectors for timber construction Typical applications and load directions for Pryda Multigrips Features Pryda Multigrips are ideal connectors for many uses in timber framing. They are suitable for high load applications such as a tie-down connector for trusses or rafters to top plates and for fixing joists to the face of bearers. Pryda Minigrips provide a more economical connector for the numerous, more lightly loaded joints in houses and other buildings. Specification The Pryda Bracing products included in these units are: Brace Product Details Product Code Mini Brace 18x16x1.2 mm Angle Brace MB36, MB42, MB48 Maxi Brace 20x19x1.2 mm Angle Brace AB36, AB42, AB48 Speedbrace 37x1.0 mm SDB12, SDB36, SDB40, SDB50, SDB60 Strap Brace 30x0.8 mm, 30x1.0 strap SB083, SB103 Warning: For the construction of bracing units don t use Hoop Iron and beware of 0.8 mm thickness (or thinner), non-engineered bracing. The latter material may be offcuts of Zincalume or Colorbond which are roofing materials having little or none of the sacrificial protection to cut edges which is a feature of the Galvabond (or equivalent) material used for Pryda products. This protection is required for good corrosion resistance in contact with mortar. All nails used for bracing units must be galvanised Pryda Timber Connector Nails (35x3.15 mm flathead), Code OSNG. Pryda will not support the use of other nails unless it can be shown by testing that the alternative nails have equivalent or better shear and withdrawal strengths. 14 Applications and Minigrips are shown below.
