2 Product Description The TRIDEK Contemporary Roofing Panel is a customised structural roofing panel designed as an alternative to conventional roofing methods. Available in straight, curved or wave curved panels, they make a great feature for any structure. The panels are light and simple to install, making installation cost effective. The panels rate highly for thermal insulation and have an outstanding spanning capability. TRIDEK Contemporary Roofing Panels are manufactured by bonding profile steel roof sheeting to the top and bottom of a low density expanded polystyrene core, to give a composite roof and ceiling panel. The panels are made in thicknesses of 75mm, 100mm, 125mm, 140mm, 165mm, and 200mm. Width varies depending on panel series chosen. Depending on the application, the panels can be made with 0.42, 0.48 or 0.60mm sheeting thickness. The expanded polystyrene is manufactured in accordance with AS1366 SL Class EPS being used. Design Mass Thickness 75mm 100mm 125mm 140mm 165mm 200mm Approx Mass (kg.m2) Panel Lengths / Cantilevers TRIDEK Contemporary Roofing Panels can be manufactured in excess of 16m in length. In length, cantilevers can be up to 3 metres. Discussion with Tridek staff and engineers is essential. In width, the roof can have a maximum unsupported overhang of 300mm. Greater distances are achievable with the use of properly engineered outriggers. Thermal Properties Thickness 75mm 100mm 125mm 140mm 165mm 200mm R Value R2.01 R2.64 R3.50 R3.65 R4.28 R5.00

The panels can be directly fixed to either a timber or steel structure. A minimum of 50mm MG10 pine for a timber structure and a minimum of 4mm thick, with a maximum of 6mm, for a steel structure is required. For a roof above 5, a wedge shaped timber fillet for load bearing of the roof is required. Marine / Corrosive Environments Use of standard TRIDEK Contemporary Roofing Panels materials should be re-evaluated when used within 1km of breaking surf or 1km of a corrosive or industrial environment.

5 Testing Composite building panels have been developed & tested around the world since the late 1960 s. More recent testing in Australia throughout the 1990 s has led to greater knowledge and confidence in the behaviour of these products. TRIDEK has undertaken a rigorous program of in-house performance and quality testing in line with AS1562 and AS4040 recommendations. Additional proof testing has also been done in conjunction with Monash University (see results next page). Test loads up to 500kg are applied to range of roof thicknesses to replicate construction, maintenance and service loads.

6 MONASH UNIVERSITY: TESTING OF ROOFING PANELS CAMT ref: prepared for: Zipperlock/Tridek Attn: Dean Rusling Factory 3, 23 Brunsdon St Bayswater Vic Tel: The testing of composite roofing panels comprising a steel profile / polystyrene / steel profile sandwich construction was requested by Zipperlock (ref. Dean Rusling, telephone conversation 02/03/05). An initial proposal was duly forwarded to Zipperlock and samples were delivered to Monash in mid August A diagram of the loading scheme is shown above; the two lower bearers were 1.8m apart centre-to-centre, and the bearers and the central loading bar traverse the entire 500mm width of the sample. The tests were done on a Instron screw driven tensile testing machine, at a displacement rate of 25mm/min. A graph of Force F as a function of displacement at the centre of the span was obtained, and the test taken to failure. Following are the graphs of load vs. extension obtained for the samples, and brief summaries of the findings.

7 The roofing structures failed by local buckling of the corrugations below the central loading bar, and the thicker composite (thicker layer of foam) failed at a slightly higher load. Each thickness was tested twice using the samples, and the reproducibility is good. The data for the roofing samples are summarised below. The failure loads can only be taken as indicative, and a suitable safety factor should be applied.

8 Zipperlock Steel Buildings Pty Ltd PO Box 932 Bayswater VIC 3153 Phone: (03) Fax: (03) WARRANTY Zipperlock Steel Buildings Pty Ltd, A.C.N , T/as Tridek Contemporary Roofing, warrants that the TRIDEK Contemporary Roofing Panel, is manufactured from first grade material and will have life prior to perforation by weathering in the natural elements of 10 years from the date of installation. The warranty is subject to the following terms and conditions: 1. The product is installed in accordance with the manufacturers published fixing recommendations current at the time of installation. 2. Installation is greater than 1km from marine environments with breaking surf, and corrosive Industrial environments. 3. The design and structural data specified is based on standard details. The successful installation depends on factors outside the control of the company. For every project, the buyers design engineer must be satisfied that the application of these guidelines will achieve the required level of structural performance. 4. This warranty does not cover any wilful or accidental damage caused by others to goods installed by the company. This warranty does not cover any erection or structural defects caused by non standard erection procedures or components. 5. Maintenance cleaning of COLORBOND pre-painted steel products is required whenever the finish is not washed by rain. Examples of applications requiring maintenance cleaning include soffits and eaves. Washing should be done at least every six months in accordance with BlueScope Steel s guidelines. If it is proven to the reasonable satisfaction of the company that any goods supplied, or any services performed by the company are defective, then the company will rectify the defect by (at the option of the company) the replacement, repair, or payment for the cost of replacement of the affected goods. This is limited exclusively to the pro-rata share of the goods, as follows: Replacement goods will be supplied at a discount, which bears the same ratio to the then current price as that part of the warranty period not achieved bears to the full warranty period.
