When faced with designing open-plan offices and large spaces such as sports halls, anything that allows for long ceiling spans must answer many architects’ prayers!

Arcelor Construction UK supplies the world’s largest range of metal decks to provide structural support for lightweight roof systems such as built-up metal, standing seam or single-ply membrane.

With spans up to 9,800mm under normal load conditions, the Arval decks negate the need for secondary steelwork and permanent bracing (as part of a properly engineered solution) to give uncluttered sightlines.

This offers architects not only ultimate design flexibility but also the ability to save on construction costs in terms of materials and labour.

The inherent strength advantages of structural decking are ideal for advanced building techniques in lateral restraint and diaphragm construction engineering which enables traditional purlins to be eliminated.

In diaphragm or stressed skin construction, a detailed structural analysis is required and Arval offers this service on receipt of general arrangement drawings of the structural steelwork and details of all applied loads.

The structural decks with profiles up to 200mm are rolled from S320GD grade steel or aluminium, with the former galvanized to BS EN 10326 to ensure quality and longevity, with a serviceable life of up to 60 years.

Perforated options that give enhanced acoustic properties make the decks particularly ideal for sports halls or swimming pools and all 30+ products are available in a wide range of finishes.

Advice on typical roof constructions and specifying the correct deck as well as deck selection tables, engineering terms, fixings and FAQs are contained in the Arval structural decking brochure.
