RD75-300 | RD75-300 CL
From the Agway 75 Series of high strength-to-weight roof decking, the RD75-300 profile is a 36” wide panel featuring 3” deep flutes, spaced 12” apart, providing the strength needed for heavier duty applications.
Our structural roof deck sections are available in a wide range of gauges in Galvanneal, galvanized or prepainted finishes: these options enable customers to determine the optimal combination of strength, performance, and affordability that best satisfies project-specific criteria. Agway roof deck sections are also available in an acoustic format with pre-punched holes in the webs of the deck which combine with acoustic batt insulation to significantly reduce ambient noise within a structure.
Bundled deck produced from either Galvanneal or G90 Galvanized coated steel is susceptible to storage stain when exposed to the elements. This staining is superficial only and is not a valid reason for rejection of this product.
