Although section depths remain the same, some flange widths have been reduced, to provide a more efficient strength/weight ratio. this, coupled with relatively minor changes to our standard sleeve details, provides a better cost effective solution. Additional gauges are now incorporated within our range, keeping Albion Sections as the cold rolled solution providing the largest choice of economically designed sections available. the standard zed and lipped channel section range offers products from 120mm to 400mm deep and 1.2mm to 3.2mm thick. due to investment in state of the art rolling and punching facilities we are able to offer a solution using both m12 and m16 bolts, with you, the customer, able to specify your preference in bolt diameter in sections up to 245mm deep. our fully dynamic pre-punch facilities also provide alternatives when considering non standard details, when using specialised cladding systems and in and around door and window openings. We at Albion are proud of our market leading delivery commitment. Planned expenditure this year has been commissioned and will provide an additional 6000 tonnes of capacity at our headquarters here in West bromwich. We also offer a full manufacturing facility in lisburn, northern ireland. this facility, opened January 2009, has capacity to support the comprehensive Albion range independently. the Albion Sigma Purlin System, launched early 2009, provides a purlin solution with a high strength/weight ratio and reduced accessory requirements. our market leading stud and track system provides effective options for infill panelling and specialised rainscreen claddings. We also offer design, detailing and installation of the system via our Associate companies. our in-house designers and sales personnel will be happy to discuss particular projects. brochure and software downloads, together with further information about Albion Sections, can be found at www.albionsections.co.uk We encourage any feedback regarding the experience of choosing Albion products; please feel free to contact us. thank you for your interest in Albion Sections.

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.

All joints to be fully sleeved. typical sleeving arrangement heavy end bay section other cleats omitted for clarity heavy end bay sleeve 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. G The penultimate rafter is sleeved with a longer sleeve of a F heavier gauge equal to the end bay purlins to cater for the all purlins single span C D higher moments in the end bay. The inner bay sleeves are slightly longer than standard sleeves with double hole punchings E for sleeve connection, and are of the same lighter gauge as 64 B intermediate purlins. 29 For the system to perform economically only buildings with a minimum of five bays should be considered.

The use of traditional tiled roof construction on steel framed buildings is becoming increasingly popular. Typical examples of this are new supermarkets which are required to blend into an existing townscape. However due to the high rotational forces imposed on the purlins caused by the high load and steep slope factors normally encountered in roofs of this type, it is essential that adequate restraining methods are employed. This can be achieved by adopting the layout shown in diagram 1 and the following points be adhered to. 1. Side rail support type struts are fixed between the purlins with a maximum unrestrained length of 2m. For spans in excess of 6m contact our Technical Department for tie wire arrangement. 2. At the bottom of the slope the struts should be fixed back to a structural member. Where no structural member exists then timber battens timber rafter timber rafter fixed as shown with site drilled holes 2 timber battens timber rafter channel or angle cleat (supplied by others) fixed with self tapping screws diagonal tie wires should be used as shown in diagram 1. 3. The maximum length of slope unsupported via diagonal tie wires or structural member should not exceed 5.4m. 4. Rigid type restraints are continued over the apex. Note: Provided the rafters are spaced at no more than 600mm centres along the purlin length the load may be assumed to be uniformly distributed.

Deflection should be taken into consideration to prevent tiles lifting, check with tile manufacturer, and recommend that deflection ratio is limited to span/250 in a vertical plain. 17 purlin systems purlins with non-restraining cladding With the increase in secret fix standing seam roofing systems which do not give lateral restraint to the top flange of the purlins it is necessary to introduce the use of lateral supports. The lateral supports are the same as the side rail supports shown on page 21 with specials manufactured at the apex to suit the required roof slope and centres. Provided the unrestrained purlin length does not exceed 2 metres, the standard relevant load tables can be used i.e. sleeved, single span, double span, or heavy end bay. Where liner panels are used and fixed directly to the top flange of the purlins and are a strong enough section to provide lateral restraint then standard sag bars can be used if required. If in any doubt contact our technical department. 2 metr 2 metr 2 metr es ma x es ma x es ma x AS 2/2010 18 purlin systems anti-sag rods (sections 125 - 266 series) speed fix anti-sag bars Speed fix anti-sag bars and apex ties are manufactured from 1.6mm thickness pre-hot dipped galvanised mild steel and cold roll formed into a channel section. Each end is notched to locate in the standard pre-punched holes at mid or 3/8 ths & 5/8 ths span and held in position with a spring. Alternative apex ties are manufactured from 12mm diameter allthread zinc plated finish. anti-sag bars serve two main purposes: • To stop the purlin twisting during erection. (once sheeting is fixed the purlin derives a large measure of stiffness from the roof membrane). • To provide lateral restraint to the bottom flange under uplift conditions. for roof slopes of 10° or more The purlin tries to roll backwards. This is prevented by fixing anti-sag bars bottom hole to top hole down the slope as shown. Note: These details apply to roof slopes up to and including 25°. For roof slopes greater than 25° consult our Technical Department. speed fix anti-sag bars are fixed continuously over the apex for roof slopes of 1.5° to 10° The purlin tries to roll forwards. Anti-sag bars should be fitted top hole to bottom hole down the slope as shown. Note: For sections 300mm deep and over 45mm x 45mm x 2mm angle struts should be used in lieu of speed fix sag rods. for roof slopes up to 1.5° For pitches at this level conventional anti-sag bars become ineffective and therefore speed fix anti-sag bars should be replaced with our side rail supports. We recommend that purlins are fixed as opposing pairs and the side rail supports fixed between the pairs. speed fix detail apex AS 2/2010 19 purlin systems long roof slopes For roof slopes in excess of 20m it is recommended that additional supports are fitted along the roof slope in the form of diagonal tie wires and side rail supports to reduce the down slope loading. typical bay plan diagonal tie wires 12mm Ø threaded rod special side rail support (1/2 cleat one end) For 300mm to 400mm deep sections replace threaded rod and anti-sag bars with side rail struts.

Albion Sections rails and fittings can provide an effective and versatile method of support. The following shows two systems which cater for individual forms of cladding used. use of horizontal and vertical rails The diagram shows a typical method of horizontal and vertical rail construction to accommodate the fixing of horizontal cladding. The horizontal rails can be selected from the relevant load tables, i.e. sleeved, butted or double span. The safe working loads for the systems may be used provided that the vertical rails are spaced at no more than 2m centres. This method gives a vertical member to which the horizontal cladding is fixed and also acts as a side rail support. 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. use of horizontal and vertical rails use of vertical rails C stanchion L C stanchion L structural members use of vertical rails This method employs vertical rails spanning between a structural top and bottom member. The rails should be fixed as opposing pairs and side rail supports fixed between the pairs at mid or third points (dependant on span).
