1. THIS PAGE IS LEFT BLANK INTENTIONALLY DO NOT PRINT Using LYSAGHT Zeds amp Cees for purlins amp girts Lysaght Zeds and Cees are used in commercial and domestic applications because they are the economical lightweight alternative to timber purlins amp girts They are Quick and easy to install using standard metal fasteners Zeds can be lapped eliminating the time consuming process of cutting to length and consistent straightness simplifies alignment Purlins Warranty Lysaght has always had the most comprehensive product warranties on the market that cover not only the corrosion performance of the material but also the structural and serviceability performance of a wide range of products Lysaght can back their products with over 150 years experience and credibility The LYSAGHT brand is widely recognised as setting the benchmark on quality products and is trusted and respected by our customers and competitors nationwide Warranty protection is available on the range of LYSAGHT Zed and Cee profiles This warranty compliments the warranties available for the L YSAGHT roof and wall cladding profiles that are commonly fixed to the purlins Application for a warranty must be lodged on our LYSAGHT Request For Warranty form available by contacting the nearest Lysaght Service Centre The warranty is available subject to application and project size Additional warranty periods with additional coating t

No Cleat connections The capacity tables are based on the sections being fastened through the web to cleats cleat connection so that the load path 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 uses two bolts Conversion of point loads into equivalent uniform loads Symmetrical equidistant point loads Loading condition Conversion formula Cladding fastened to this flange Lap varies according Narrow Flange to span and section size Narrow Flange Bolt in web at end of lap Bolt in flange at end of lap Cleatless connections Fixing of purlins through the bottom flange of the purlin cleatless connection is used in some forms of construction The purlin capacity tables should not be used for these types of connections For these types of connections there are other design issues both strength and serviceability and construction issues that need to be considered Contact your local Lysaght Service Centre for more information The number of bolts used are halved compared with the number used in conventional cleated connections Lapping Simple m w 2P L The structural lap at the interior supports of piden lapped configurations mus

Fascia Bridging Clinched Clamp End Adjustable Bridging Girt Hanger Standard Bridging Locator End The LYSAGHT HOOK LOK II bridging system is the most adaptable and flexible bridging system available to securely brace both Zed and Cee purlins and girts of depths 100 150 200 and 250mm It is also fast and easy to install and can accommodate most construction configurations The system consists of solid bridging assemblies between purlins and girts and adjustable bridging assemblies at locations such as eaves ridge and girt foot Purlins and girts display two types of lateral instability lateral deflection and twist rotation or roll It is necessary to control these instabilities by providing suitable bracing as close as possible to the flanges of the section Bracing can be continuous such as rigid cladding suitably fastened to the flange or point bracing at the midspan region or at a point of maximum bending or several points at the midspan region In practice Lysaght claddings with screw fasteners are a suitable lateral bracing when attached to the flange However as with all thin walled claddings the twisting resistance is difficult to quantify Consequently point bracing is still required to resist twist of the section and lateral deflection of the free flange Point bracing is also required to stabilise and straighten the purlins and girts prior to fixing ofthe cladding in order to facilitate the fixing op
