Note: That in both sleeve systems, sleeves are provided to all purlins on the penultimate rafter
single span with staggered sleeve arrangement
single/double span with staggered sleeve arrangement
The sleeved system is the most popular and widely specified system for buildings of 2 bays or more. It provides a cost effective solution combined with ease of detailing to many building designs.
double span butt joint system (purlins & rails) The double span butt joint system is not as efficient in load carrying capacity when compared to the sleeved system, however, when load criteria allows choice of system then this is the more cost effective, saving on component parts and site erection time.
single span butted system (purlins & rails) The single span butted purlin/rail (non continuous system) is the most simple of all the systems. Used generally for shorter spans or where lighter loads apply as in agricutural buildings. It is economical, easily detailed and purlins can be fitted either over the rafters or between the rafter webs.

heavy end bay section
lighter inner bay section inner bay sleeve
The heavy end bay system offers an economic solution to the larger and multispan type building, with the inner bays being of a lighter gauge material. The system caters for spans up to 15m dependant on loading criteria, and is a fully continuous purlin system, with sleeves at every joint. The penultimate rafter is sleeved with a longer sleeve of a heavier gauge equal to the end bay purlins to cater for the all purlins single span
higher moments in the end bay. The inner bay sleeves ar e slightly longer than standard sleeves with double hole punchings for sleeve connection, and are of the same lighter gauge as intermediate purlins. For the system to perform economically only buildings with a minimum of five bays should be considered. The heavy end bay system can also be supplied with the inner bay purlins double spanning with single span purlins introduced to stagger the rigid joints; as shown in the diagram. Note: Rigid joint of double span purlins can be in line but
inner bay purlins double span
rafters need to be checked for extra stress.

side rail systems diagonal tie wires mid point support
The drawings on the following pages show typical applications of a side rail support system for mid and third point supports which will suit most conditions Diagonal tie wires should be used where there is not a suitable structural eaves member for supporting the side rail system, or
detail A
where the height of the structural eaves member exceeds that shown on the diagram. Where diagonal tie wires are used, they can be fixed as shown between the bottom two lines of rails ensuring a straight line is acheived, and progressively working up the side of the building with rails and rail supports so the rail supports are in compression. Alternatively diagonal ties can be fitted at eaves level between the top two lines of rails and work down the building so the rail supports are in tension.

rail systems firewall restraint system (1m or more from relevant boundary) In certain applications it is necessar y to include fire protection to some or all of the perimeter walls around a building. There are many fire resistant wall cladding sy stems available today, which attach to Zed or C Section rail systems. The side rail system described below combined with the fire r esistant cladding system have been tested and have achieved a four hour fire resistance.
Under fire conditions the side rails will expand. To achieve the necessary movement either the column fixing cleat or the rail is slotted longitudinally as shown in the detail below with 62mm clearance to allow for expansion. Note the slotted cleats are supplied by others. It is important that all the fixing bolts are fitted with combustible washers which under fire conditions will collapse enabling
Although testing was carried out on our rail system for four hours the period of resistance is solely dependant on the type of cladding materials used and their construction and therefore certification should be obtained from the cladding supplier.

Note: If four or more rows of vertical rails are used per bay additional diagonal tie wires may be required. Details shown are diagramatic only, both vertical and horizontal rails can be either zed or channel sections. Fixing cleats to vertical rails can be pre-fabricated to suit hole patterns and spot welded to vertical rails on request. Cleats are fabricated from 3mm thick galvanized mild steel.

The rails should be fixed as opposing pairs and side rail supports fixed between the pairs at mid or third points (dependant on span). The vertical rails should be selected from the single span load tables. If height to eaves exceeds available rail capacity additional structural rail supports should be provided or horizontal and vertical rail system used.

building, special side rail supports can be used to hang from the eaves member. If the rails are being hung from a cold rolled eaves beam then the capacity needs to be checked for extra load. Eaves struts are required on spans 4m and above

to resist twisting from combined loads of gutter weight and wind.
eaves strut side rail support
When gutter straps are fitted to the top flange of eaves purlin additional bracing is required to prevent excessive torsion. In most cases side rail supports acting as struts at mid or third points are sufficient, however, depending on design criteria such
