CUSTOM ORB CUSTOM BLUE ORB DESIGN AND INSTALLATION GUIDE

LYSAGHT CUSTOM ORB & CUSTOM BLUE ORB TRADITIONAL CORRUGATED STEEL CLADDINGCUSTOM ORB is the famous corrugated profile, equally at home with traditional and contemporarydesign. It is a wide, strong and lightweight profile that can be quickly and easily installed. Add up thesefeatures and you have a steel roof or wall cladding that simply offers outstanding value.The gently curving shape of the classic Australian roof is reflected in some of today’s most adventurousand dramatic designs. CUSTOM BLUE ORB is the corrugated profile for curving, allowing the expressionof this quintessential Australian style. It is the perfect match to harmonise with our well-known, traditionalCUSTOM ORB .16mm CO17mm CBOStandard COLORBOND steel is available in a select range ofcontemporary colours suitable for all building projects.COLORBOND STEEL WITH THERMATECH TECHNOLOGY762mm coverMATERIAL SPECIFICATIONSNext generation ZINCALUME aluminium/zinc/magnesium alloycoated steel complies with AS 1397:2011 G550, AM125 (550 MPaminimum yield stress, 125g/m2 minimum coating mass).

COLORBOND steel with THERMATECH technology reflects more of the sun’sheat, allowing both roofs and buildings stay cooler in summer.In moderate to hot climates, compared to roofing materials ofsimilar colour with low solar reflectance, COLORBOND steelwith THERMATECH can reduce annual cooling and energyconsumption by up to 20%.LENGTHSSheets are supplied custom cut.CUSTOM ORB MASSESBMT (mm)kg/mkg/m2m2/tZINCALUME steel0.423.264.28234230COLORBOND steel0.423.324.35ZINCALUME steel0.483.704.86206COLORBOND steel0.483.764.93203kg/mkg/m2m2/t CUSTOM BLUE ORB MASSESBMT (mm)ZINCALUME steel0.604.596.02166COLORBOND steel0.604.646.09164ZINCALUME steel0.80*6.067.96126COLORBOND steel0.80*6.128.03125 *0.80 BMT CUSTOM BLUE ORB available in South Australia only.TOLERANCES (CUSTOM ORB & CUSTOM BLUE ORB )Length: 10mm, – 10mm, Width: 4mm, – 4mmSHEET LENGTHSSheet lengths of up to 24m can be used before an expansion jointis required for roof applications.2

MAXIMUM SUPPORT SPACINGSThe maximum recommended support spacings are based ontesting in accordance with AS 1562.1:1992, AS 4040.1:1992 andAS 4040.2:1992.Roof spans consider both resistance to wind pressure and lightroof traffic (traffic arising from incidental maintenance). Wall spansconsider resistance to wind pressure only. The pressure consideredis based on buildings up to 10m high in Region B, Terrain Category3, Ms 0.85, Mi 1.0, Mt 1.0 with the following assumptions made:ROOFS:Cpi 0.20, Cpe -0.90, Kl 2.0 for single and end spans,Kl 1.5 for internal spans.CURVINGCUSTOM ORB is not intended for machine curving. For bullnosinguse CUSTOM BLUE ORB . Long, curved lengths of CUSTOMBLUE ORB can be easily placed and aligned. From the traditionalbullnosed verandah, to the double curves and complex shapes ofmodern homes and offices, we offer a full range of curving styles tosuit almost any building.The extra ductility of CUSTOM BLUE ORB allows easy curvingwithout distortion of its profile, and without damage to the finish.Ensure you order the appropriate profile for the job.USE CUSTOM BLUE ORB FOR CURVESCURVING RADIIWALLS:Cpi 0.20, Cpe -0.65, Kl 2.0 for single spans and end spans,Kl 1.5 for internal spans.The minimum curving radius is 300mm (400mm in Victoria). At theend of a curve, there must be a straight vertical section of at least100mm (80mm in Victoria).These spacings may vary by serviceability and strength limit statesfor particular projects.CURVING TOLERANCES CUSTOM BLUE ORB Straight vertical min.

INSTALLATIONFASTENING SHEETS TO SUPPORTSCUSTOM ORB (and CUSTOM BLUE ORB ) are pierce-fixed totimber or steel supports. This means that fastener screws passthrough the sheeting.You can place screws through the crests or in the valleys. Tomaximise watertightness, always place roof screws through thecrests. For walling, you may use either crest or valley-fixing.Crestfixing for roof or wallscladding to timber support.TRIMDEKAlways drive the screws perpendicular to the sheeting, and in thecentre of the corrugation or rib.Don’t place fasteners less than 25mm from the ends of sheets.SIDE-LAPSCrest fixing for roofs or walls.CUSTOM ORB (and CUSTOM BLUE ORB ) is overlapped at thesides not less than 1.5 corrugations. It is generally considered goodpractice to use fasteners along side-laps however, when claddingis supported as indicated in maximum support spacings, side-lapfasteners are not usually needed for strength.Pan/Valley fixing for walls onlyDon't fix here becauseunderlapped sheet would leak.Pan fixing for walls only.Crest: 3 fasteners †END LAPPINGEnd-laps are not usually necessary because CUSTOM ORB andCUSTOM BLUE ORB are available in long lengths.Crest fixing: 4 fasteners per sheet per support.Pan/Valley: 3 fasteners †side-lapIf you want end-laps, seek advice from our information line on thesequence of laying and the amount of overlap.UnderlapOverlapCrest: 5 fasteners †If you intend to end-lap CUSTOM ORB (and CUSTOM BLUEORB ), order the sheets at the same time and tell us you intend tolap them, to ensure a good fit of the profiles.Pan fixing: 4 fasteners per sheet per support.side-lap fastenerPan/Valley: 5 fasteners †ENDS OF SHEETSIt is usual to allow roof sheets to overlap into gutters by about 50mm. The valleys of sheets should be turned-down at lower ends,and turned-up at upper ends.side-lap† Fasteners per sheet per support. Most common practice is:3 fasteners for internal spans and 5 fasteners for single and end spans.LAYING PROCEDUREFor maximum weather-tightness, start laying sheets from the endof the building that will be in the lee of the worst-anticipated orprevailing weather.Sheet 3Sheet 2Sheet 1Prevailing weatherDirection of layingLay sheets toward prevailing weather. Also, it is much easier andsafer to turn sheets on the ground than up on the roof.Before lifting sheets on to the roof, check that they are the correctway up and the overlapping side is towards the edge of the rooffrom which installation will start.Place bundles of sheets over or near firm supports, not at mid spanof roof members.SHEET COVERAGEWidth of Roof (m)34567891011121314151617181920304050Number of Sheets46781011121415161819202123242527405366CUSTOM ORB CUSTOM BLUE ORB 6

All screws with EPDM sealing washer.WALKING ON ROOFSTURNING-UP CUSTOM ORB OR CUSTOM BLUE ORB When walking along the length of CUSTOM ORB , walk only in thepans. When walking across the width of the sheeting, walk over orclose to the roofing supports. Generally, keep your weight evenly distributed over the soles ofboth feet to avoid concentrating your weight on either heels ortoes. Always wear smooth soft-soled shoes; avoid ribbed soles thatpick up and hold small stones, swarf and other objects.MAINTENANCEOptimum product life will be achieved if all external surfaces arewashed regularly. Areas not cleaned by natural rainfall (such as thetops of walls sheltered by eaves) should be washed down everysix months.STORAGE AND HANDLINGKeep the product dry and clear of the ground. If stacked orbundled product becomes wet, separate it, wipe it with a cleancloth and stack it to dry thoroughly.Handle materials carefully to avoid damage: don’t drag materialsover rough surfaces or each other; carry tools, don’t drag them;protect from swarf.With pliers, multi-grips or a shifting spanner closed down toapproximately 2mm, grip the valley corrugations 20mm in fromthe end of the sheet and turn up as far as possible. Be careful not totear the sheet.SEALED JOINTSFor sealed joints use screws or rivets and neutral-cure siliconesealant branded as suitable for use with galvanised orZINCALUME steel.SIMPLE, LOW-COST FIXINGCUSTOM ORB and CUSTOM BLUE ORB can be fixed withhex head screws ensuring fast and simple installation with therecommended side-lap (one and a half corrugations).SWARFSweep all metallic swarf and other debris from roof areas andgutters at the end of each day and at the completion of theinstallation. Failure to do so can lead to surface staining when themetal particles rust.METAL & TIMBER COMPATIBILITYLead, copper, bare steel and green or some chemically-treatedtimbers are not compatible with this product; thus don’t allowany contact of the product with those materials, nor discharge ofrainwater from them onto the product. If there are doubts aboutthe compatibility of products being used, ask for advice from ourinformation line.CUTTING7Cut materials over the ground and not over other materials. Sweepall metallic swarf and other debris from roof areas and gutters at theend of each day and at the completion of the installation. Failure todo so can lead to surface staining when the metal particles rust.CUSTOM ORB CUSTOM BLUE ORB For cutting thin metal on site, we recommend a circular saw with ametal-cutting blade because it produces fewer damaging hot metalparticles and leaves less resultant burr than a carborundum disc.
