Type "B" Wide Rib
The Type B Wide Rib is the industry standard for industrial metal roofing. It can be produced in Galvanized Steel, Painted Steel, aluminum, and stainless steel. All lengths are produced to custom requirements. Standard width is 36" coverage. This product has excellent load carrying capability. The wide rib allows for a narrow top opening, which is desirable when rigid insulation is to be used on top of the deck. When computing coverage requirements, allow for laps at supports.Type B Wide Rib Metal Roofing
Type "F" Intermediate Rib
The F Intermediate Rib is an older deck profile still widely used, particularly where roofs must nest with an existing Type F Roof. All attributes that apply to B Deck also apply to Type F.Type F Intermediate Rib Metal Roofing
2 1/2" Rib
The 2 1/2" Rib Panel can be used to replace conventional 2 1/2" CORRUGATED metal while allowing for vastly improved carrying capabilities it gives more of a building panel appearance. This shape can roughly approximate in 28GA the load carrying capability of 2 1/2" CORRUGATED metal in 24GA.2.5 inch rib panels
1 1/2" Composite
1 1/2″ Composite Floor Deck is available in Galvanized steel, Painted Steel, and Stainless Steel. Again, the web is indented to allow bonding between the concrete and the composite deck. Lengths are rolled formed to customer specifications. Standard cover is 36″. Stainless Steel 1 1/2″ Composite Floor Deck is available where extreme corrosion resistance is required. As with all decks, T304 and T316 Stainless Steel is available.1.5 inches Composite floor deck
2" Composite
2″ Composite is available in Galvanized Steel, Painted Steel, and Stainless Steel. Composite Deck is meant to be used as a floor deck where concrete is to be poured on top of the deck. The web in the deck contains indentation, which allows for better bonding between concrete and deck, and therefore forms the Composite Deck. Temporary shoring may be required during construction. Consult the catalog for spans where shoring is required. 2″ Composite comes roll formed to any custom length required and comes in 24″ width and interlocking side lap. Stainless Steel Decks provide the ability to prevent deterioration associated with conventional galvanized Deck thereby eliminating debris falling from the ceiling. Both Type T304 and T316 are available.2 inch composite metal floor deck
N Deck
The 3″ depth of N Deck 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 it’s long span capability, the use of N Deck will minimize support requirements. The narrow spacing between the ribs of the N Deck allows for rigid insulation or pouring concrete. The load carrying apabilities of the N Deck generally surpass that of other long span metal decks. N Deck is available in Stainless Steel, both T304 and T316, and is suited for caustic environments. It is also available in Galvanized, Galvalume, and Painted steel.N Deck metal panel
