F Deck

An economical, intermediate-ribbed roof deck

F Deck
F deck is a cost-efficient roof deck option suitable for numerous applications

Type F (intermediate rib) roof deck provides an economical choice for applications where insulation requirements are lower. Where rigid roofing insulation is used with F deck, a minimum 1-inch thickness is required.

F deck is available in lengths from 6’-0” to 40’-0”. Check with your local New Millennium facility for lengths outside these parameters. Conforms to ASTM A1008/A1008M for uncoated and painted deck, A653/A653M for galvanized deck. Approved by UL, ULC and listed in the UL and ULC Fire Resistance Directories.

Yield strength up to 80ksi. Refer to published tables for the minimum yield strength used for each deck type. Contact New Millennium for availability of higher yield strengths when required or use our deck specification tool to view load tables with commonly available non-standard yield strengths and/or gages.
