Why the USA Uses Dovetail Decking & R51+ Roof Decking
Dovetail decks and R51+ roof decks are preferred in the U.S. construction market because they offer:
Architectural-grade underside finish
No extra ceiling required.
Easy installation of MEP systems
HVAC, lighting, and pipelines can be hung directly from the profile ribs.
Superior composite action
Dovetail and R51+ ribs increase stiffness, reduce deflection, and enhance load capacity.
Long-span capability
Highly suitable for warehouses, offices, steel structures, and multi-story buildings.
Available in acoustical versions
Ideal for stadiums, public buildings, and parking structures.
