N Deck & Decking

Long Span Metal Decks

The 3" depth allows for longer spans not possible with lesser depth profiles. The increased span capability allows the use of a lighter gauge, which can prove to be cost effective. Also, because of its long span capability, the use of the N Decking will minimize support requirements. The narrow spacing between the ribs of the N Deck allows for rigid insulation or pouring concrete. The load carrying capabilities of the N Deck generally surpass that of other long span metal decks. N Deck is available in corrugated stainless steel, both T304 and T316, and is suited for caustic environments. It is also available in galvanized, galvalume and painted steel.
