SMD structural roof deck products are typically used as the structural deck (tray) for various insulated roof systems including:

• Single Ply Membrane
• Double skin built-up system
• Standing Seam
• Green Roofs
• Asphalt

Using the Elements® (Roof deck option), full structural calculations can be prepared with a diaphragm design service available upon request.

The use of a structural deck in place of a more traditional liner provides benefits from design stage right through to construction:

• In many instances, site operatives can walk directly on the profile without the need for crawl boards
• The longer span nature of structural roof decks results in less secondary members giving an aesthetic uncluttered soffit whilst also saving time during erection of the frame

All SMD deck profiles, ranging from 30mm to 200mm in depth are designed in accordance with BS EN 1993-1-3, with product designs complemented by structural testing.
