1.0 Deck

A big value for small support spaces

1.0 Deck
Type 1.0RD roof deck helps contain costs while meeting support space requirements

Type 1.0RD roof deck provides an economical option when support spacing is small. Where rigid roofing insulation is used with 1.0RD deck, a minimum 1-inch thickness is required.

Type 1.0RD roof 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.
