DESIGN & SPECIFICATION

MATERIALSMetroll Megaspan® purlins and girts are manufactured from hi-tensile G450, G500 or G550 galvanised steel, with a minimum Z350 (350 g/m2) galvanised coating conforming to AS 1397.

CORROSION PROTECTION & MATERIAL COMPATIBILITY

Some building materials and environmental conditions can be detrimental to coated steel products irrespective of the product thickness. This includes contact with or exposure to runoff from:

• Industrial, agricultural, marine or other aggressive atmospheric conditions

• Incompatible metals such as lead or copper

• Building materials subject to cycles of excessive moisture content such as non-seasoned timber

• Materials which have been treated with preservatives such as CCa or tanalith treated section.

The standard Z350 (350 g/m2) galvanised coating will provide a long and trouble free life for enclosed buildings and open sided rural applications in non-aggressive environments. For more severe corrosive environments a Z450 (450 g/m2) will be required. This heavier coated product is available subject to minimum order quantities and lead times.

METROLL MEGASPAN®

HOLE PUNCHINGMetroll C and Z purlin sections are normally supplied with holes punched to the AISC guide except in VIC where 150mm sections are punched to Structural Steel Fabricator Association Victoria recommendations (70mm centres).

Holes are required at cleat supports, laps bridging points or as specified on detail sheets supplied prior to manufacture. The preferred method of dimensioning is hole centre to hole centre rather than referenced from one end. An overall purlin length is required to provide for a data entry dimensional check.

Metroll Megaspan® Purlins are a range of performance enhanced C & Z Purlins. The profile has been optimised to deliver capacity improvements of more than 20% compared to standard purlins.

IMPORTANT NOTE Standard purlins MUST NOT be substituted for designs using information from this Megaspan® Design Manual. Megaspan® is a higher performance section, standard purlins will not deliver the same load capacities and may be under-engineered and potentially unsafe.

APPLICATIONMetroll Megaspan® purlins and girts are primarily used in the design of sheds, industrial and commercial buildings. The sections are typically used to support roof and wall sheeting..

FASCIA PURLINS*Fascia Purlin design varies significantly across Australia. Different applications require different section size and configuration. Metroll manufacture a range of fascia purlins including the popular Fluted Series. These purlins feature a fluted web which adds strength and provides a flush external face when used with flat headed fascia bolts. The added advantages of this section include a down turned lip for wall fixing and a variable upturned top flange for roof pitches from 5° to 30°.

It is common practice to use a standard C section in place of a fascia purlin in fascia applications. The C section can be supplied as a standard configuration or with the top flange bent to

suit the roof slope.

SHEETING LENGTHS & EXPANSION JOINTS

Roof sheeting lengths are limited by several issues - thermal expansion, transport limitations and practical handling are the main items governing maximum sheet lengths. The following table provides recommended maximum sheet lengths. This may vary from state to state. Contact your local Metroll branch for more information.

DESIGN ASSUMPTIONSThe tables in this brochure are for limit state capacity, which means that any load beyond the tabulated loads will prevent the member from fulfilling its intended function. This may mean reaching a limit state for collapse or loss of structural integrity. The limit state capacity tables for various purlin combinations in this publication provide economic design solutions for most projects. In special projects a more optimal design can be obtained by varying combinations, such as:• Material specifications• Bolt specifications & quantity• Lap length• Bridging quantity• Span range• Reduced or enlarged end spans• Cantilevers at one or both ends of the configuration• Loading

Design calculations are based on AS/NZS 4600:2005 Cold Formed Steel Structures, and follow criteria established by industry best practice.Assumptions inherent in the code provisions and validated by them include:• Self-weight is not included in the design load tables.

Self-weight shall be added to any load cases assessed.• Capacities are calculated on the basis of loading

applied to the flange of the section, where the cladding, screw fixed to the flange, provides a minimum level of rotational restraint of 10,000 Nmm/mm.

• The Z shaped section behaves as an equivalent C shaped channel in the strong axis.

• The design assessment includes consideration for distortional buckling.

• For all systems, loading is assumed as uniformly distributed and acting on all spans simultaneously. All other load configurations must be specifically designed.

• Where multiple spans are specified, these are of equal dimension.

• All section properties stated are for full sections, (holes not deducted from the web).

• The loading condition diagrams show the loads applied to the cladding, transmitted via screw fixing into the top flange and acting in the direction shown by the arrows. This defines the ‘inward’ and ‘outward’ load directions.

• For Serviceability Conditions, the limiting deflection is Span/150.

USING THIS MANUALWhen selecting purlins real applied loads must be considered along with the stated capacities in this manual. All spans are considered loaded concurrently and no allowance has been made for uneven or skip loading. Where this is likely, or where loading conditions vary from those designed for in this manual, a structural engineer should verify compliance independently with AS/NZS 4600:2005.

this manual, this may not necessarily ensure competency of the selected system. Member adequacy is dependent on the maximum moments applied and the moment profile within the member span.These design actions can vary widely under real, project specific, applied loads and it is the responsibility of the project design engineer to verify their purlin selection is compliant with AS/NZS 4600:2005 and AS/NZS 1170 Assessed Loading.

TOLERANCESAll sections will be produced with the following tolerances. Please contact your Metroll branch if any variation is required.Overall Length ±5mm Flange Width ±1mm Depth ±1mm Hole Centres ±1.5mm

STRUCTURAL LAPPINGA feature of Megaspan® Z sections is one broad and one narrow flange proportioned so that two sections of the same size, when one is flipped over 180 degrees, can overlap and bolt snugly together.Structural continuity results in better economy but lapping provides two thicknesses of material over interior supports, increasing the strength of the sections where bending moments and shears are maximum thus improving the load capacity and rigidity of the system. C sections cannot be lapped.All lapped Z section configurations generally require a total lap length (bolt centre to bolt centre) of 15% of the span (to the nearest 50mm).Structural laps provide greater load carrying capacity to the section. The lap/span ratio must be 15% or greater and all laps should use six bolts in the connection including two bolts in the bottom flange.Z sections can be lapped in any thickness combination which allows for heavier, stronger sections to be used in end bay applications.

LAPS FOR UNEQUAL SPANSFor unequal spans the total lap length must be 15% of the average span and the lap is not equally spaced across the support. In practice 7.5% of the longer span must be applied to the shorter purlin as this material ends up in the longer span. Conversely 7.5% of the shorter span should be applied to the longer span. This is demonstrated in the example diagram below:

10,000 900

750 12,000

Drawing not to scale

An alternative is to apply the 15% lap based on the longer of the spans.

BRIDGINGThe limit state capacity tables provide design solutions for an equal number of rows of bridging in each span. Provision is made for 0, 1, 2 or 3 rows.In some combinations of span configuration and loading there is no benefit in increasing the number of bridging rows.Metroll recommends that bridging is installed such that the maximum unbraced length is 20 x D (D = purlin web height), or 4000mm, whichever is the least. In addition to enhancing purlin performance this requirement assists with the installation of roof sheeting. Location of the bridging must be as shown below (to the nearest 50mm), or as determined by the design engineer.

MEMBER WEIGHTAll limit state loads are in kN/m. Limit state loads make no allowance for the mass of the member. In some cases, limit state loads are limited by the bolting.

DEFLECTIONThere are no specific rules governing acceptable deflections, though structural codes give guidance. One needs to consider the specific requirements of any structure. It may be necessary to design under more than one load combination. Load stated is calculated to produce a deflection of Span/150 for the critical span. Solutions for other deflection ratios may be obtained using linear proportioning. Where a suspended ceiling is to be installed, such as in residential and commercial construction, more stringent deflection limits may be necessary to prevent damage to the ceiling components or joints. Both the end span and the internal span must be considered in the analysis of lapped and continuous spans.

CLEAT CONNECTIONSThe limit state capacity tables are based on the sections being fastened through the web to the cleats so that the load is via the web of the sections.The connections may be single section thickness such as in end connections, or the internal support connection of continuous configurations. Connections with double section thickness occur at the internal support of lapped configurations.Each connection consists of two bolts. The bolt specifications (size and grade) will depend on the section size and design load. In some cases, eliminating cleats and bolting directly through the bottom flange for the Z and C sections could save on the number of bolts required. The number of bolts is halved compared with those in conventional cleated connections.Single cleats are most commonly used with Z sections and double cleats with C sections. Double cleats can also be used in applications with a high reaction load to reduce bolt stress and sheer. Extra care is required with hole detailing in double cleat application to a single purlin. The following table illustrates industry standard cleat sizes including purlin clearances.

* 70mm in VIC

† 50mm in VIC + When using down turned lip purlins or girts the lip length must be added to the dimension B and Y. Cleat lengths may be increased in some design situations (e.g above an expansion joint).

As a guide, increase the cleat thickness by 2mm for each 40mm of additional length.

BOLTSThe fastening of sections to cleats is normally by standard Metroll purlin bolts. In the limit state capacity tables, where high strength bolts govern the capacity the loads are marked accordingly. In these situations the section capacity is not fully utilised and it may be more economical to select another configuration or change the spacing of the section or increase the bolt number of specification.Purlin laps must be bolted in the top web hole and the lower flange holes at both ends of the lap. Bolting only the web of lapped purlins does not provide full structural integrity and excessive loads can be placed on the roofing screws that penetrate both purlin thickness in the lap region. The correct size and grade of purlin bolts nominated by the design engineer should be used at all times. Bolts should be fully tightened prior to roof installation and before any loads are applied to the purlins, girts or bridging.Bolts to be snug tightened to a nominal torque of 54Nm.

POINT LOADS (SEE TABLE OVER PAGE)

The limit state loads specified in the tables are essentially uniformly distributed. It is inferred that all design loads will be converted into uniformly distributed values. In some applications the design loads are point loads. All design loads must be converted to uniformly distributed loads.The point-loaded configuration has been equated with uniformly loaded configuration for conversion formulae for single spans and lapped span configurations and are provided as a guide in the table on the following page. For continuous unlapped configurations a separate set of conversion formulae is applicable.

INSTALLATIONPurlin and girt installation should be carried out in suitable weather conditions by experienced crews.

SAFE WORK PRACTICESMetroll Megaspan® purlins and girts are not designed for walking on. Residual oil from the manufacturing process may be present and slipping can occur. Appropriate lifting equipment and work platforms must be used.As a minimum:• Never walk on purlins or girts during installation. Use

appropriate equipment.• Never walk on bridging.• Ensure safety mesh is in place.• Always use approved safety harnesses and/or other

suitable safety equipment during installation.

WELDINGWelding of Megaspan® purlins, girts and bridging is not recommended. Welding any cold rolled, high tensile material affects the material properties and removes the galvanised coating. This can cause reduced life of the member.

DESIGN CAPACITY TABLES

SPAN INFORMATION & SUPPORTING TABLE

The tables indicate the maximum limit state capacity of the sections. Capacities are based on uniformly distributed loads and any point loads need to be converted.

Required loads are established by a project designer using the appropriate building codes and standards. Once the

purlin and girt outwards and inwards loads are determined the preferred span configuration can be checked using the tables.

When using the Safebridge® bridging system 3 rows of bridging should be selected.

MET-LOCK BRIDGINGMet-Lock Bridging by Metroll is an uncomplicated proprietary system developed for fast installation and optimum compatibility with Metroll purlins and girts. (In WA this system is called Tab-Lok Bridging and components differ).

Met-Lock Bridging can be installed in a number of ways. The usual method is to commence installation at the fascia and proceed up the roof slope to the ridge.

The system consists of solid bridging assemblies between purlins/girts and adjustable bridging assemblies at locations such as ridges, eaves and the bottom of girts (girt foot).

BRACING Purlins display two types of lateral instability; lateral deflection and twist (rotation and roll). It is necessary to control these instabilities by installing suitable bracing as close as possible to the flanges of a section.

Bracing can be continuous (cladding fastened to the flange), or point braced at the midspan region or at several points on the midspan region. Point bracing is required to stabilise and straighten the purlins and girts prior to the fixing of cladding in order to facilitate the fixing operation.

Common point bracing types are ties, these can be loaded in tension only. Because they are solid members, Met-Lock components secured to the web of purlins and girts can be loaded in tension, compression and bending. For this reason a continuous run of bridging is the most effective stabiliser for both roof and walls. It is also the most widely accepted by design engineers.

Met-Lock components are simple yet robust. Installers do not have to worry about additional clips or ends that distort with slight impact. Locators and Clamps have hook centres to match holes punched in corresponding purlins and girts.

*NOTE: In WA the bridging system is called Tab-Lok. Components vary.

MET-LOCK BRIDGING - TYPICAL ASSEMBLIES

INTERMEDIATE BRIDGING Intermediate Bridging is the basic connecting member between purlins and generally comprises a Locator End and a Clamp End attached to cut-to-length Plain Channel.

All bridging lengths should be centre to centre dimensions. Metroll programming deducts the purlin thickness to ensure the correct spacing is manufacturing.

GIRT BRIDGING Girt Bridging is usually made up of: an Adjustable Girt Foot, Intermediate Bridging and a Girt Hanger. The recommended installation procedure and precautions are required.

1. The roof sheeting should be installed before the Turnbuckle or Girt Hanger us used to level the Girts which would impose loads on the fascia system; and

2. A temporary girt support under the bottom girt is required until installation of the wall cladding is complete.

GIRT FOOT Girt Foot assemblies are used to transfer downward forces in girt bridging to the floor. They also provide some adjustment and alignment to the bottom purlin.

LARGE BRIDGING Metroll's Large Bridging is for Metroll's large purlin range (C/Z300, C/Z350 and C/Z400 series). Like the Met-Lock range, the heavy duty range is simple and easy to install, Components are larger because the sections are more substantial.

Generally the Bridging Channel is a C150 section firmly bolted to end plates at 90°. If a particular angle is required at the bridging ends it must be specified at the time of order. Additional costs may apply.

BASIC COMPONENTS All Metroll components are manufactured from zinc coated steel and form an integral part of the Metroll purlin and girt system.

TYPICAL ASSEMBLY

GIRT BRIDGING INSTALLATION The recommended procedure for the installation of Girt Bridging is to start at floor level and work up the walls toward the fascia or eaves. A typical installation is as follows:

STEP 1: Install the Girt Foot assembly by engaging the Locator into the appropriate holes in the bottom girt. Due to the transference of loads, Girt Feet assemblies must be anchored to the slab.

STEP 2: Adjust the Girt Foot assembly to level the bottom girt. Where the slab has not been poured or a Girt Foot not specified, the bottom purlin must be temporarily supported to keep it level.

29

BRIDGING INSTALLATION Following are the recommended safe and practical steps for the installation of the Met-Lock Bridging System. Procedures will vary from state to state, however standard practice is to commence purlin installation at the fascia and work up the roof slope to the ridge line.

STEP 1: FIX FASCIA BRIDGING Install the Fascia Bridging by inserting the Locator End into the holes of the first purlin and bolting the Fascia Bracket to the Fascia Purlin. Adjust the Slotted Channel to straighten the fascia and bolt firmly.

STEP 3: INSERT INTERMEDIATE BRIDGING Install the Intermediate, Locator/Clamp Bridging up the roof slope and finish at the ridge. Intermediate bridging is installed by fitting the Clamp End (the straight bracket) over the previously installed Locator (the cranked bracket) and swinging the bridging piece around until the Locator engages the holes of the next purlin.

Fit the Clamp end over the installed Locator and swing the bridging piece around so the Locator engages the holes of the next purlin. Repeat for subsequent bridging.

STEP 4: REPEAT WHERE APPLICABLE Repeat Step 1 and Step 2 where applicable on the opposite side of the roof. Face bridging pieces in the same direction for a neat appearance.

STEP 5: FIX RIDGE BRIDGING Install the Ridge assembly by fitting the Clamp Ends over the previously installed Locator Ends and tighten the bolts or turnbuckle of the Ridge assembly.

If a Ridge assembly is not used, the last piece of Intermediate Bridging should end in a Bolted End Bracket which can accommodate a Sag Rod if required at a later date. Alternatively the standard bridging can be secured in position by installing a bolt beside the previously installed Locator

BRIDGING SYSTEM - OVERVIEW

SAFEBRIDGE®

PURLINS-BRIDGING INSULATION SYSTEM

Megaspan® purlins are compatible with the SafeBridge® Purlins-Bridging Insualtion System. SafeBridge® is an innovative, award winning roofing system that can be adapted to almost and commercial or industrial roof structure. Fully compliant with the current requirements of the BCA, Section J, SafeBridge®

utilises the existing purlin space to provide energy efficient roof insulation without compromising roof height, wind rating or structural integrity.

IMPORTANT DESIGN CONSIDERATIONS

The SafeBridge® system relies upon specific purlin spacing outlined below. Please ensure you consult with Bradford and Metroll early in the design phase to understand the relationship of purlin depth and spacing to R-value and the BMT relative to your ultimate roof design loads.

PURLIN & BRIDGE BAR SPACING

KEY BENEFITS• Can achieve high thermal performance in any climate

zone (as defined by the BCA.NCC)

• Code compliant with BCA/NCC Section J.

• Utilises the purlin space without elevating the overall roof or fascia height. No roof spacers required.

• Suitable for both cyclonic and non-cyclonic regions.

• Retains the structural integrity and load points of the roof interior.

• Suits most roof pitches and complex roof designs.

• Available in foil, decorative or acoustic finishes on the internal faced insulation material.

• Creates a safer roof environment for workers during construction.

DESIGNING FOR GREEN STAR & BUILDING CODE COMPLIANCE

Minimum energy efficiency standards for commercial buildings are mandatory in the BCA and NCC. Thermal insulation plays a key role in meeting these requirements and contributes to reductions in energy use which is a critical factor in Green Star accreditation. Choosing the right insulation also offers additional benefits of condensation control, noise dampening and control of heat flow in and out of the building.

To achieve the BCA/NCC Section J thermal insulation values, the roof system must allow sufficient space under the roof sheeting for insulation to recover its design thickness and achieve its rated insulation value. Failure to provide enough space will result in compression of the insulation and reduce its performance. SafeBridge® use the depth of purlins to provide a cavity for the insulation to recover its thickness, rather than create a space above the purlin using a roof spacer. Safebridge® allows purlin spacing to be set at a predetermined height during the design phase by way of a patented bridging system and key way.

DESIGNING FOR WORKER SAFETY

A unique feature of the SafeBridge® system is the application of safety mesh between, rather than over the top of the purlins. This eliminates the need to lap safety mesh and cover the purlins, resulting in immediate material cost savings. This method also facilitates the use of the SafeBridge® Wire Pulley system which saves installation time and also removes workers proximity to the exposed edge of the roof during construction, greatly increasing worker safety.
