ResinDek® B Deck Corrugated Metal Decking
Industrial Platform Decking
Cornerstone Specialty Wood Products, LLC® provides corrugated metal deck products in a variety of profiles, thicknesses, yield strengths and finishes. The Engineers at Cornerstone Specialty Wood Products will help you optimize sizes, runs, steel thicknesses, corrugated profiles, and beam spacings, thus saving you time and money. To assist with the ease of installation we can even supply pre-punched B Deck and N Deck for use with our Invisi-Loc® underside fastening system.
Corrugated metal deck products are available in a variety of gauges and finishes. A bright white underside is available for excellent light reflectivity, but gray primer, galvanized or stainless steel is also available. We recommend that a minimum of 20 gauge (.9 mm) metal B Deck and N Deck be used on all 3/4″ (19 mm) ResinDek flooring projects.
