6 INTRODUCTION This pulication has een prepared to assist the designer in specifying Metalcraft Super Span (MSS) Purlin and Girts, Metalcraft C Section (MC Section), complete with either Camlok or Standard Bracing systems and MS Tophats. MSS Purlin and Girts, MC Sections, with the Camlok or Standard Bracing system are designed for use as a olted framework system used with primary structural steel work. They are supplied cut to length and can e pre-punched with a variety of holes to suit a numer of applications. Purlins, Girts and Bracing are rollformed to provide an efficient, lightweight support system for roofing and wall cladding and are recognised as eing efficient, economical structural memers suitale for a wide range of uilding applications. The Camlok Purlin Bracing system provides a complete, efficient, cost effective and easily erected system. MSS Purlin and Girts, and MC Sections, complete with either Camlok or Standard Bracing systems and components are a complete system, supplied ready for erection and will require minimal maintenance throughout the life of the uilding. The Z275 galvanised finish on the purlins and racing systems, give an excellent corrosion protection and reduces the need for painting. MSS Purlin and Girts, MC Sections, Bracing systems and MS Tophats, comply with New Zealand Building Code, and are designed to AS/NZS 4600:2005 Cold formed steel structures. MS Tophats can e used for roof purlins, wall girts and floor joists, and are an economic option for these and other applications. They are an economical alternative to timer and C section purlins for spans up to 7 meters. Easy to use they fasten directly to their supports which eliminates the requirements for cleats. Being symmetrical there is no requirements for races or nogs to prevent twisting and allows the profile to e easily lapped for maximum performance. MS Tophats are manufactured from high strength galvanised steel coil, the Z275 minimum coating provides good protection in most exposed internal environments. Consideration should e given when used in a lined exterior dwelling. Thermal reaks are required etween the tophat and cladding to avoid thermal ridging. Contact with materials not compatile with zinc should e avoided. HANDLING AND STORAGE The presence of water etween the stacked sections will create premature corrosion, it is recommended the sections are separated and dried if this situation occurs. Cutting if required should e done with hacksaws or snips, the use of arasive disc lades are not recommended. EFFECTIVE DESIGN WIDTH Metalcraft Roofing does not provide values of the effective design width of section elements and where required must e considered y the Design Engineer. DISCLAIMER This pulication is intended to provide accurate information to the est of our knowledge in regards to MSS Purlin and Girts, MC Sections, Bracing systems and MS Tophats Sections.

9 DESIGN CONSIDERATIONS 1.0 AXIAL & FLEXURAL LOADING 1.1 General MSS Purlins and Girts have een designed to comply with the requirements of AS/NZS 4600:2005 (Cold Formed Steel Structures). Strength Reduction Factors are in accordance with 1.6 of the aove Code. ie. Bending = 0.90 Axial c = 0.85 The self weight of the purlin is not included in the load tales and should e added along with other dead loads. All loads are ultimate loads for strength calculations, and serviceaility loads for deflection calculations, all in accordance with AS/NZS Vertical loads on purlins The load span tales show (ultimate uniformly distriuted load in ) for estalishing the purlin strength. Any other loading format must e specifically designed. The restraints as set out in 2.0. must apply. w x (applied uniformly distriuted load in ) for maximum inwards and outwards load cominations, (derived from AS/NZS 1170) is required in order to estalish the strength requirement for the purlin. The load span tales also show w s (serviceaility load ) for estalishing the purlin stiffness ased on deflection at those loads of L/150. The applied serviceaility load is required for maximum inwards and outwards load cominations. 1.3 Axial Loads with/without Flexure, Symols N* = Applied ultimate axial load. cnuc = 0.85Nuc = The memer capacity in compression (). wx = Applied uniformly distriuted ultimate load (). wu = Maximum U.D.L (ultimate) from the tales. = 0.9 (strength reduction factor in ending). Cmx = 1.0 For oth ends unrestrained. αnx (Ref. AS/NZS 4600:1996 clause.1) N* = 1 ( N e) Ne = Elastic uckling load aout the ending axis. 1.4 Axial loads only The memer capacity in compression = c N uc from the axial load tales Axial load and ending cnuc must e determined for the level of restraint provide ie. (a) 1,2 or 3 lateral races. For ending aout the major axis (X axis) the interaction equation elow applies: ( ) ( ) N* + C mx w x c N uc α 1.0 applies nx Bending For ending aout the minor axis, (y axis) and for i-axial ending, calculations from first principles must e carried out. 1.5 Braces The standard racing channel is limited to a purlin spacing of 3000mm. 2.0 RESTRAINT 2.1 General The following restraints are required to achieve the taulated loads. 2.2 Roof Purlins with uniformly distriuted loading One flange of purlin to have roof cladding with normal screw fixings. Providing minor axis rotation restraint of Nmm/ mm. Compression flange not restrained y roof sheeting to e restrained y lateral races as shown in the tales. For pitches over the resultant forces in the plane of the roof must e allowed for. 2.3 Girts with horizontal loading Vertical loads are carried y the racing system, connected to primary structure capale of supporting the vertical load. A maximum race spacing of 3000mm with sheeting screw fixed to the girts provided minor axis rotation restraint of Nmm/mm. 2.4 Roof Purlins with comined axial load and ending Restraint y races with roof sheeting to one flange is required. 2.5 Columns Axial Load only Restraint as selected for the relevant c N uc value adopted from the tales. 2.6 Comined Axial and ending As noted in 2.4 aove ut the level of restraint applicale must e determined. Metalcraft Roofing Structural Guide Revision April

10 MSS & MC DESIGN & SELECTION These Tales have een prepared on the following asis: Roof sheeting screw fixed to the top flange. The self weight of the purlin is not included in the load tales. All spans for continuous lapped memers and doule lapped spans are assumed to e equal. These tales are for use y structural engineers and it is assumed they will derive linear loads inwards and outwards on memers. Standard racing channel is limited to a purlin spacing of 3000mm. All tale capacities refer to uniformly distriuted loads. Load applied through top flange. Design Loads calculated for load spans as follows: Lap length is the maximum of 10% x span or 600mm. Minimum olt size is M16 (G8.8/S). IMPORTANT In the design of continuous lapped span memers, the specified end span and internal span loads are assumed to act concurrently with all spans loads at specified load capacities. Design Engineers must e aware that patch loading or situations where applied loads vary from the specified loadings (from this ook) in any one or all spans, adequacy of the specified system must e verified y the Design Engineers for compliance with AS NOTE: Memer adequacy is highly dependent on the maximum applied moment and the moment profile within the span. SINGLE DOUBLE LAPPED Load Capacity is calculated uniform across 2 spans TRIPLE LAPPED Load Capacity are calculated uniform across 3 spans MULTI LAPPED "end span" "internal span" mirror line End spans are the minimum capacities from doule lapped or triple lapped case. Internal spans capailities are corresponding maximum load applied uniformly to all internal ays. 10 Metalcraft Roofing Structural Guide Revision April 2016

N* = Ultimate axial load applied to the α nx C mx = 1 c N uc Ne purlin (). = 1 ( N* Ne ) = Axial load capacity from the tale. = Elastic uckling load from the tales. 2. UNIFORMLY DISTRIBUTED LOAD ON ROOF PURLINS Design Example Restraints Screw fixed roofing provides a fully restrained condition for downwards (or inwards) loading. Braces provide lateral restraint for upwards (or outwards) loading. Span L = 10m Purlin Spacing = 1.6m Derived loadings/m on purlins from known dead load, live load & wind pressure on the roof. Serviceaility w S = 0.72 = 0.24 Calculated Ultimate Load w X = 0.89 = 0.99 Serviceaility Maximum deflection or = Try: 250/15 From load span tales for 10.0m span ws = 0.7. Therefore: 250/15 OK. Ultimate Loads: Check: 250/15 From load span charts for 10.0m span & 2 races w = 1.24 > 0.89 u 10.0m span & 2 races w = 1.32 > 0.99 u Therefore: 250/15 with 2 races is OK. 3. UNIFORMLY DISTRIBUTED LOAD ON ROOF PURLINS PLUS AXIAL LOAD Design Example As in 2. But an axial load extended on the purlin from wind pressure on the end wall of the uilding.

15 PRODUCT INNOVATION Metalcraft Roofing has made a quantum leap forward in product range and manufacturing process with the commissioning and installation of its new purlin machines at the Metalcraft Roofing manufacturing plants in East Tamaki and Christchurch. There are many great features with the new purlin machine. The machine is completely automated which means that operator error is reduced as purlin quantities, lengths and punching requirements are handled at the order entry stage. In comparison to raft ased purlin rollformers which require lengthy change over times Metalcraft s purlin machine make the necessary changes in a matter of minutes. The gain in production flexiility allows for improved service levels to the customer. Quality is something that Metalcraft Roofing prides itself on and the new purlin machine has improved production design that ensures that the end product is of the highest quality. Traditional Purlin machines cut the purlin after it has een formed. In order to ensure the purlin is cut and does not flare, older machines will tend to overform the purlin. This means as it passes through the guillotine at the front of the machine the galvanized coating can e shaved on the inner side of the purlin. The Metalcraft Roofing purlin machine overcomes this y cutting the purlin to length efore it is rollformed. Again this is all done y an automated system that means there is less room for error as information is not doule handled. To further assist on site the individual purlin data is inkjet printed onto each purlin for ease of identification. Product Innovation is crucial to the success of any industry. Metalcraft Roofing has innovated y releasing four new purlin sizes, 275/15, 275/18, 325/15, 325/18 which are unique to the Metalcraft Roofing range.

106 BRACING SYSTEMS Metalcraft has two racing systems, Camlock and Standard. All Purlins and Girts should e raced to maximise the design limit of the component. It is recommended that at least one row of racing e used on any span, particularly if temporary loads may e experienced during construction. If the racing is required to support super imposed dead loads (eg. lighting, sprinklers) specific design will e required. Camlock is a racing system that has no sag rods to place and no olts or washers to fix. This has proven to save up to 75% of time in Bracing installation, giving considerale cost advantages. Metalcraft MSS Purlin and Girt system has een designed for olting to cleats using the tales provided for hole and cleat dimensions. M12 or M16 Class 4.6 olts and washers must e used. Design Engineers should give consideration to the olt diameter, washer size and cleat material and thickness to e used also considering the reaction caused y doule or continuous spans and high loads. The racing systems are formed from galvanised Grade 250 steel.

124 MS TOPHATS DESIGN GUIDE INTRODUCTION MS Tophat can e used for roof purlins, wall girts and floor joists, and are an economic option for these and other applications including carports and fencing. They are an economical alternative to timer and C section purlins for spans up to 7 meters. Easy to use they fasten directly to their supports which eliminates the requirements for cleats. Being symmetrical there is no requirements for races or nogs to prevent twisting and allows the profile to e easily lapped for maximum performance.ms Tophats are manufactured from high strength galvanised steel coil, the Z275 min coating provides good protection in mostexposed internal environments. Consideration should e given when used in a lined exterior dwelling; thermal reaks are required etween the tophat and cladding to avoid thermal ridging. Contact with materials not compatile with zinc should e avoided.ms Tophats comply with the New Zealand Building Code, and are designed to AS/NZS 4600: 1996 Cold formed steel structures. HANDLING AND STORAGE Care should e taken to ensure MS Tophats are kept dry during transportation and storage. The presence of water etween the stacked sections will create premature corrosion, it is recommended the tophats are separated and dried if this situation occurs. Cutting if required should e done with hacksaws or snips, use of arasive disc lades is not recommended. PURLIN & GIRT Metalcraft Roofing manufactures MS Tophats, which can e used as Purlins and Girts, for the New Zealand construction market. MS Tophats are cut to length and are availale in a range of sizes and gauges to suit a variety of applications. The MS Tophats are manufactured from high tensile Z275 galvanised coil in accordance with AS1397. MS Tophats are an economical alternative to C shaped purlins and girts as well as timer forspans up to 7 metres. For more information on MS Tophats contact your local Metalcraft Roofing Branch. FLOOR JOISTS Metalcraft Roofing MS Tophats can e used in a variety of applications, one of those eing as a floor joist. For further information on MS Tophats eing used in this way please contact your local Metalcraft Roofing Branch.
