Why Use Stainless Steel Metal Deck?
While it's common to see cold rolled painted, or galvanized (G-60 or G-90) finishes specified for metal decking. Occasionally highly corrosive environments require stainless steel finish.
For hot dip galvanizing the G-60 coating means there will be .6 oz of zinc per square foot overtop the raw steel coil. G-60 is the most common type of galvanized metal decking. It is used on more than 90 percent of metal deck jobs that are specified as galvanized. Similarly G-90 means .9 oz of zinc per square foot will be coating and therefore protecting the steel. Primarily we see G-90 galvanized metal decking specified on a job in a corrosive environment such as a project that is close to the ocean or perhaps above an enclosed chlorine pool.
304 Stainless Steel
304 SS nickel and chromium content provide corrosion and oxidation resistance. O'Donnell Metal Deck's 304 SS metal deck coils are suitable for use in mills, chemical processing, food dairy and other industries.
316 Stainless Steel
316 SS coil contains nickel, chromium and adds molybdenum which increases the corrosion and oxidation resistance to withstand more severe environments with more industrial chemicals and solvents. O'Donnell Metal Deck's 316 stainless metal deck coils are suitable for use in pulp and paper mills, textile mills, oil and gas industries or wherever there are inks, bleaches and dyes.
Stainless Steel Metal Deck Supplier
O'Donnell Metal Deck offers T-304 metal deck and T-316 metal deck for corrosive industrial environments. If the EOR or specifier has not determined which finish is required on the project be sure to clarify which stainless steel metal deck is required before reaching out for a quote.
While the structural properties of both finishes are comparable, the difference between 304 and 316 stainless steel is that 316 has more nickel and more molybdenum. The increased nickel and molybdenum makes 316 stainless steel deck a better choice for most chemical applications when compared to 304 stainless steel deck.
The bottom line is this, the added compounds required for 316 Stainless Steel Deck also makes 316 a more expensive coil.
