Based in Sherburn, North Yorkshire, we operate one of the largest and most advanced production complexes in Europe, manufacturing over 50,000 tonnes of steel products each year. In over five decades of trading, we have become an established market leader, renowned for our quality products and innovative designs. Our comprehensive range of cold-rolled structural products includes composite steel floordecks, purlin and rail systems and a range of ancillary products: Multibeam is a range of purlin and cladding rail systems that are suitable for all types of modern roof construction with bay sizes up to 15m. Multibeam cladding rail systems are designed specifically to support metal-clad walls in horizontal or vertical orientation; Multichannel is a range of pre-engineered, structural channel sections designed to complement the Multibeam purlin and rail systems. Multichannel is an ideal solution for vertically or horizontally-laid cladding and can be an effective substitute for conventional hot-rolled sections and timber; Multideck is a high-performance, profiled, galvanised steel floor decking for use in the construction of composite floor slabs. Multibeam Kingspan 5 Multibeam Kingspan Benefits Quality & Durability SCILGA Accreditation All products are manufactured from the highest quality materials The Multibeam purlin and rail system has SCILGA accreditation. using state-of-the-art production equipment to rigorous quality Gold Standard control standards; ensuring long-term reliability and service life. Kingspan Structural Products & Systems have been awarded All products are fully compliant with ISO 9001 (Quality), ISO 14001 the Gold Standard under the Steel Construction Sustainability (Environmental), ISO 50001 (Energy) and OHSAS 18001 (Health Charter (SCSC). & Safety). This simple coherent business management system enables the organisation to successfully achieve its purpose CE Mark and mission to ensure that quality; safety and the environment Kingspan Structural Products have CE accreditation; please visit are considered in all aspects of the business process. Further our website to view the relevant certification. The accreditation information on these certifications can be found on our website was carried out by the Steel Construction Certification Scheme www.kingspanstructural.co.uk (SCCS). Environmental The Multibeam system has been engineered to ensure maximum performance whilst minimising the material content. Individual sections are packed together using low carbon mild steel, blued and waxed banding which is wholly recyclable. Identification of the bundles is by paper labels which are biodegradable and can be recycled. Any wood products, used to support the bundles in transport, are sourced from either UK FSC forests or sustainable European forests with management systems in place to ensure that trees are replaced and processes meet the criteria of the Kingspan Group Forest Disclosure policy. Steel does not lose its strength or stiffness over time so remains a viable product for reuse. Assembly joints between components can be easily dismantled at any time to facilitate reuse. Sections can be recut to length and reholed to suit a revised use. Steel is one of the world’s most recycled materials with over 40% of ‘new’ steel made from recycled steel. Kingspan’s suppliers encourage, promote and assist in the return of steel for recycling. 6 Kingspan Multibeam Multibeam Product Overview With simple connections and economical Eaves Beam sections, Eaves Beam is compatible with all types of cladding in modern roof construction. You can’t get it wrong with Multibeam purlins; The unique sigma shape is ‘non-handed’, making it the most versatile purlin on the market today. Multibeam Kingspan 7 Multibeam Purlins & Rails Multibeam purlin and rail system typically require fewer components than other systems. This means quicker assembly and faster project completion. Multichannel Multichannel can be used for a myriad of applications such as horizontally laid cladding rails, gable posts, door and window trimmers and floor joists. 8 Kingspan Roof Multibeam Purlins Heading Roof Purlins 9 Heading Roof Purlins Roof 10 Kingspan Roof Purlins Multibeam Product Overview “ The sigma shape of Multibeam makes it stiffer than other common shapes of purlin so it can be handled practically on larger spans ” Multibeam purlins are suitable for all types of modern roof construction with bay sizes up to 15m. Range Multibeam is designed to create a structure with fewer Section heights from 145mm to 350mm components than other systems and is lighter for easier site Flange standard widths from 65mm to 90mm, up to 95mm handling, stiffer for straighter cladding lines, stronger for longer also available (see page 26) spans and greener due to reduced steel content. This means Gauges from 1.2mm to 2.7mm that it saves you time, lowers your costs and provides greater sustainability. For full product dimensions see page 18. Other sizes may be available on specific request. Please contact our Technical Applications Department for advice. All types of roof cladding Pitched, mansard, curved or flat roof applications Lengths All lengths are catered for; requirements in excess of 18m, Roof slopes from 0°to 60° please contact our Sales Department. Bay widths up to 15m Material Specification Hot dip galvanised steel to BS EN 10346 and BS EN 10143 ‘specifications for continuously hot dip zinc /metal coated structural steel strip’. The minimum grade of steel used is S450GD, with Z275 zinc coating, giving an average coating thickness of 0.02mm to each side. Other coatings maybe available (G600 / Magnelis).

Sleeves are used to provide continuity at the joints between Multibeam can be supplied in various lengths, please check members and are available in three gauges (see page 22). with our Sales Department for lengths over 18m. When joining two sections of different gauges (as in a HEB system) use the heaviest gauge purlin to select the sleeve for that joint. Continuous Span - Heavy End Bay This system is often referred to as Heavy End Bay because Double Span a thicker gauge of section is required in the end bays of the Double span lengths of Multibeam section span across three building, although all internal bays are a lighter gauge.

What is a truss? A “truss” is formed when structural members are joined together in triangular configurations. The truss is one of the basic types of structural frames formed from structural members. A truss consists of a group of ties and struts designed and connected to form a structure that acts as a large span beam. The members usually form one or more triangles in a single plane and are arranged so the external loads are applied at the joints and therefore theoretically cause only axial tension or axial compression in the members.
