Corrugated Metal Roofs and Siding

Corrugated Metal Roofing – 1 1/4" x 1/4"

The slight or small profile of this corrugated profile is often used in decorative applications where strength is not an issue. The panels are offered in almost every type of material, and mostly made to order. The majority of these panels are offered in a 26" wide with 33" in some materials. Primarily only offered in light gauge thickness, since this profile does not carry a heavy loads.

Corrugated Galvanized G-90 – 2 1/2" x 1/2"

Box Beam – 5.33"

Sometimes referred to as a "Super 4 RIB", this 1 1/2" deep product has an extra bold ribbed appearance. The higher strength characteristics of this box beam can lesson the number of structural steel girts on large tall buildings.

Rib – 4"

The 4" Rib is very popular profile that used both as a siding and roofing panel. The 4" Rib is typically ordered as a Mill finish aluminum and Stucco-Embossed finish. The additional strength panel would come in the galvanized finish, with load tables available for all the types of material. Call for other sizes other than the .032 and .040 aluminum, and 18, 20, 22, 24 gauge galvanized finishes. Common uses are warehouse and industrial buildings. If there is a certain material you would like your 4" made to, please call as we do form custom panels.

Rib – 8"

The 8" Box-Rib is used in many paper & Pulp plants. This profile has stiffing beads which will minimize any type of canning that can occur with other panels. The painted finish is the primary way this ordered but can also be order as a mill finish in whatever material you choose. All standard gauge thickness and sheet sizes apply when ordering the 8" Rib Panels.

Roof Decking, Steel Roof Deck, and Floor Decking Panels

Roof Decking – Type “A” Deck
A Narrow rib decking roofing panel is designed to give maximum strength structurally while minimizing cost. The sheets will nest into each other on the width side, for easy installation. The A-Deck is usually offered in Painted or Galvanized using 18-20-22 gauge thickness.
Wide Roof Decking – Type “B” Deck
The B-Deck or B-Wide Rib panels are the most popular decking panels we offer. This standard panel can be used in all aspects of industry, as either roofing or siding material or for pouring concrete. The standard 1 ½" high 36" wide panel’s come in a heavy (G-90) galvanized finish to eliminate any deterioration from the outside elements. The stocking sizes at Mechanical Metal, Inc. are either, 8′, 10′, or 12′, but feel free to request over 20′ in length. The standard gauges in stock would be the 18-20-22 thickness but others can be done as well. As the industry standard panel, this can be shipped with minimal lead times. The closure fasteners, strips, and any other accessories can be shipped quickly as well.
Floor Decking – Type “F” Deck
Type F deck, with its medium rib opening, is designed to provide the most economical combination of deck and insulation. Its nestable design eliminates the need to die-set ends and speed insulation.
Roof Decking – Type “N” Deck
Type N is a deep rib deck that is especially suited to the 10’0 to 15’0 span conditions. The long span capability of this section lends itself to canopy and other installations where a long clear span is desirable. This section is available in an acoustical version, galvanized finish.

Composite Decking, Galvanized Composite LOK Floor Decks

Composite Floor Deck LOK – 1 1/2"
The 1 ½" deep composite floor decking panels are primarily used for pouring concrete slabs. The louvers formed into the sides of all composite decks aid in the adhering of your concrete pour, adding strength to your flooring applications. All Load tables are available upon request from Mechanical Metal, Inc. The standard galvanized finish will come in either the 22 or 20 gauge thickness, but 18 and 16 gauge are also available. The 1 ½" comes in the 36" wide sheet and lengths up to 24′ 0" Long.
Composite Floor Decks LOK – 2"
The 2" composite floor deck, which is made in the 24" panel width, is used for all concrete slabs. The galvanized or painted finish is stocked in the 20 gauge thickness, and any length size up to 24′ Long. Please call for pricing and Mechanical Metal, Inc. will be happy to help you with your installation.
Composite Floor Deck LOK – 3"
The 3" Composite floor decking is the deepest and most structurally sound concrete flooring panels available. The deep profile allows a deep and stronger pour of concrete therefore a higher slab depth can be had. As with all the floor decking panels the widths allow for easy installation with the male and female receptors. Please call for additional information, or for load tables on any of our floor decks.

Stock List

Type "B" Wide Rib
The Type B Wide Rib is the 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 capabilities. 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 "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.
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.
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.
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.
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.
7.2 Thermalwall Roofing Panels
