Multichannel - Overview Multichannel Applications - Horizontally laid cladding rails - Parapet posts - Mezzanine floors - Brickwork restraints - Door and window trimmers, ribbon windows - Wind bracing - Columns - Gable ends - General engineering applications Material Specification Hot dip galvanised steel to BS EN 10326:2004 and BS EN 10143:1993 ‘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 galvanised coatings may be...

Why Multichannel? Multichannel sections offer lightweight robust construction and may be used in lieu of some hot rolled sections, offering easier site handling. Multichannel is suitable for a wide range of structural applications including horizontal cladding support, door and window trimmers, wind bracing, mezzanine floor beams, brickwork restraints, gable rafters and columns. Autoform® In Autoform® Ends The unique feature of the Multichannel system is the Autoform® End. Autoform® eliminates the need for fixing cleats and brackets which simplifies the construction process by providing...

Restraints - Vertically Laid Cladding Half bay width Restraints for Bays up to 6.1m The single strut system is utilised on buildings with bays up to 6.1m centres with adjustable diagonal tie wire as shown in the diagram. Eaves Beam Maker up Bays up to 3.0m generally do not require vertical support struts. This system is for use with cladding which, when fixed restrains the Multibeam siderail outer flange. * When wall exceeds 10m in height allow one set of diagonal ties for every 9.0m of height. Maximum rail cross centres are 2m. For larger cross centres, contact Kingspan technical. Max...

Restraints - Firewall This assembly of Multichannel side rails is designed to offer lateral support to the cladding assembly, which provides the firewall performance of insulation integrity and stability for the periods derived from test or assessment. Periods up to 240 minutes are possible. Firewall systems rely on the performance of the cladding. As the sheeting rails are relatively thin components they have very little heat sink capacity owing to their low mass. When subjected to a fire resistance test, the sheeting rails are heated very quickly and consequently lose their structural...

Restraints - Horizontally Laid Cladding Cladding joints at Stanchions This typical example also shows vertical restraint provided by standard diagonal tie wires and the connection to the Eaves Beam system.

Cladding Joint Within Span Where cladding is joined within the bay span a wider flange is required in order to ‘butt’ the panels together. For this detail a G140/150 section is used together with screwed rod diagonal.

Multichannel - Applications Parapet Posts Multichannel can be used as an efficient and economical parapet post section to support vertical or horizontally laid cladding on industrial and commercial buildings. Tapered packing (if required) Gable with Parapet Verge parapet flashing Compound Multichannel Fascia Post The Multichannel parapet post can be supplied as a kit for assembly on site or as a fully assembled component ready to attach to the main steelwork and complete with attachment cleats to suit Multichannel or Multibeam horizontal cladding rails. Use the Toolkit design software to...

Mezzanine Floors Multichannels can be used for primary or secondary floor beams in mezzanine floor applications. They can also be used singly or compounded to form columns, and can be used as stair rails and treads providing a completely pre-engineered mezzanine floor package. Multichannel Mezzanine floor beams can be utilised with all popular types of flooring including checkerplate, timber etc. They can be fitted between steel or over steel supports either with or without cleats. Fitting over steelwork gives the economy of double span members but increases the depth of the floor...
