3.0 Composite deck is distinguished by its 3" depth and embossments that are nested inside the flutes of the deck. These embossments bond with the concrete during the curing process to become part of the structure. If you need help with a speciation or design intent, give us a call.

3.0 Comp Sidelap Attachment(s)

Metal deck sidelap attachments are the fasteners that connect adjacent sheets of steel deck at their overlapping edges, commonly known as side laps. The EOR or design team, is responsible for specifying the type and spacing of sidelap attachments. This specification is crucial as sidelap attachments play a vital role in the structural integrity of the metal deck, the diaphragm to resist lateral forces from wind or seismic activity.

STITCH SCREWS

High Shear Stitch Screw sidelaps are designed to be fastened by stitch screws. This type of metal roof deck is designed to be screwed at the side lap and NOT welded. Normally stitch screw is used in short to medium span conditions.

NESTABLE

Nestable deck is also designed generally for screw side lap style of B decking. Note the nestable side lap has a lower shear value and must be determined by the EOR.

WELDED

Interlocking sidelaps without a proprietary sidelap tool indicate a top seam weld or button punch is required. Note this is can / would be the same deck profile as PLB or DGB however, the attachment pattern would indicate the proprietary tool may not be required.

PROPRIETARY CONNECTIONS

Propriety sidelap connections require the use of the manufactures proprietary sidelap connection tool. These tools must be used for the side lap attachment or the building design could fail. Below are the most common sidelaps connections in the market.

Composite Finishes:

The metal deck finish is the coating on the steel deck surface, which will vary depending on the application. The EOR or design professional is responsible for specifying the finish of metal deck on a job by job basis.

Roof deck finishes are most commonly shop coated, G-60 and G-90 varieties.
Composite deck finishes typically uses galvanized steel to promote a bond with the concrete. Note composite decks cannot have a painted top surface as it creates potential bonding issues between the concrete and the metal deck.
Form deck finishes are most commonly to be galvanized, or galvanized top with a painted bottom.

PRIME PAINT	A1008	Prime Painted Steel Decking: A temporary, provisional primer (gray or white) applied to cold rolled steel, offering protection before field-applied finishes and most often used for roof deck.
G-30	A653	Galvanized G-60 zinc coated steel is the standard in the deck industry. G30 has approximately 0.3 ounces of zinc per square foot. Generally for warehouse or large sq ft.
G-60	A653	Galvanized G-60 zinc coated steel is the standard in the deck industry. G60 has approximately 0.6 ounces of zinc per square foot.
G-90	A653	Galvanized G-90 is typically specified for exterior applications or more corrosive enviromentys with approximately .9 ounces of zinc per square foot.
FINISH PAINT	A653	Finish Paint: Specialty finishes (Epoxy or Tenmic) can be applied either pre- or post-manufacturing, most common in highly corrosive environments rather than architectural coats.
GALV + PAINT	A653	Galvanized + Paint: A combination of galvanization and primer, ideal for projects requiring both corrosion resistance and the ability to apply additional field paints.
PHOS PAINT	A1008	Phosphatized Painted: Steel decking with a phosphatized black surface that develops slight rust before concrete is poured, with the underside painted for additional protection.

Cellular, Acoustical & More

3" Steel Decking and special variations such as cellular, cellular & Acoustical and/or vented composite decking are generally specified by the EOR or design professional to meet requirements on a project. The choice of a variation is determined during the design phase and typically requires a special manufacturing process, or coil. Note these variations are often indicated structural design drawings or specifications.

CELLULAR COMPOSITE

Cellular metal deck consists of a flat bottom steel sheet with a deck profile attached either by welds or rivets. This creates pockets or cells where the deck that can be used for various purposes such as electrical wiring to be threaded through.

Composite Cellular Acoustic Metal Deck Rendering

CELLULAR ACOUSTICAL

Cellular Acoustical applications come with factory-installed sound-absorbing insulation into the flutes or cells of the metal deck. Cellular acoustical decks are available in both roof and floor deck profiles offering the same structural capabilities as the standard deck profile

Metal Deck Hangar Tab Vents

3" COMP VENTED

Slotted or vented metal roof deck offers factory-punched vent tabs to ensure effective airflow to aid in curing concrete or to prevent moisture from being trapped in the slab during slab waterproofing applications. Consider that when venting metal deck, minor leakage can occur during concrete placement. The row configurations vary by profile; contact us for more details.

Certifications

The specific certifications required for a project are typically outlined in project documents, including specifications, drawings, and contracts. There are many reasons why metal deck certifications are important, we are ready to help you through the submittal process for any and all certifications with proper documentation.

	SDI Members The SDI (Steel Deck Institute) provides uniform industry standards for the engineering, design, manufacturing, and field application of steel deck. We only supply materials SDI Approved to promote safe and effective construction practices. Learn more about why the SDI is important at SDI.org.
	Domestic Steel We can supply the required steel MTRs or mill certificates as required for evidence of domestic steel. We are able to meet both Buy America and Buy American requirements. Be sure to notate this with our sales team at the time of order.
	Factory Mutual (FM) FM Global is a commercial property insurance company that also provides loss prevention engineering services and sets property loss prevention standards, including standards for building materials. FM Approved metal deck is designed to meet these specific standards for fire resistance and structural performance. Our products meet meet Factory Mutual (FM) Approvals as: FM Global's RoofNav program, may be searched using "steel deck". Note that specific assemblies within RoofNav do not list specific steel decks so as not to unnecessarily restrict what can be used. For an expanded list of allowable spans based upon FM Standard 4451 please contact us.
	UL Approved Verco deck is UL approved. UL (Underwriters Laboratories) approved metal deck refers to steel products that have been tested and certified by UL to meet specific fire resistance standards. For projects that require spray-on fireproofing, it's essential to specify paint finishes that are compatible with the applicable fire-rated assembly, as not all paints are approved for use in such assemblies. Search for approved UL Assemblies.
	IAPMO Reports Certified with IAPMO Reports. This code reports play an important role facilitating product evaluation processes and provides a service by issuing an informed third-party opinion that a new or alternative structural product meets the intent of the codes, which is essential to the building industry and the public's wellbeing. Contact us to obtain the current IAPMO ES Evaluation Report for your project.
	LEED Compliant Metal decks can contribute to LEED (Leadership in Energy and Environmental Design) certification for a building by supporting the construction of energy-efficient and resource-conserving buildings. LEED certified metal deck is metal deck that is manufactured with recycled steel and/or manufactured within 500 miles of the job site. Discuss with us how we can help ensure your metal deck is qualified for LEED certification.
	Los Angeles Research Report (LARR) The Los Angeles Department of Building and Safety (LADBS) offers two types of building material and product approvals: General Approval Also known as a Research Report (LARR), this approval is for mass-produced products that can be used on any project site. An evaluation report from an approved product certification agency can demonstrate that a material or product meets the code requirements. The report must be based on the model codes that are current at the time the plan is submitted. Contact us for the current City of Los Angeles Research Report Letter.
