Roof Deck
RDI roof decks are available in a range of standard 1-1/2 and 3-inch deep fluted configurations to provide an economical choice for most projects and structural designs. These efficient narrow, intermediate and wide rib profiles with 6 or 8 inch rib spacing, varying material thick nesses and painted or galvanized finish permit flexibility in satisfying specific project conditions.

Form Deck
RDI form decks are available in 9/16, 1-5/16 and 1-1/2 inch deep profiles to serve as either a structural support for lightweight insulating fills or a form for reinforced structural concrete slabs. These products are available in varying material thicknesses and a galvanized finish to offer the design profession a variety of choices.

Composite Decks
RDI composite floor decks are available in 1-1/2, 2 and 3 inch deep fluted profiles to act as a permanent form and the positive bending reinforcement for the structural concrete slab. These configurations with 6 or 12 inch rib spacing, varying material thicknesses and a galvanized finish provide a selection of floor designs and the option for composite beam design.

Finishes
RDI steel roof, form and composite floor decks are available with the following standard finishes as indicated in the section properties table for each specific product.
