Metal Deck Products: A Guide to the Full Keystar Steel Deck Line

Most jobs need more than one kind of steel deck. A single building might call for Type B roof deck over the main bays, composite deck on a second floor, form deck at a mezzanine, and a list of closures, pour stops, and sump pans to finish it all off. Sourcing those metal deck products from one supplier saves phone calls, simplifies deliveries, and cuts down on the small misses that hold up a crew.

This guide walks through the metal deck product line we carry at Keystar Industries: what each product does, where it gets used, and how to choose and order the right one. We are a locally owned steel deck distributor in Eagan, Minnesota, and our product is USA manufactured and cut to order.

Metal Deck Products at a Glance

Here is the full lineup in one place. Use it as a quick reference, then read the sections below for the details that affect your choice.

Product	Profiles We Carry	Primary Use	Choose It When
Type A roof deck	1.5″ narrow rib	Low-slope roofs	Thinner insulation board needs narrow flute openings, or matching existing A deck
Type F roof deck	1.5″ intermediate rib	Low-slope roofs, repairs	Matching existing F deck or a middle ground between A and B
Type B roof deck	1.5″ wide rib, ribs at 6″ o.c.	Most commercial roofs, mezzanines	Standard spans and the most common spec
Type N roof deck	3″ deep rib	Long-span roofs	Wider joist spacing or heavier loads
1″ / C deck	1″ shallow	Short spans, venting, acoustic uses	Tight spans or special applications
Composite floor deck	1.5″, 2.0″, 3.0″	Concrete floor slabs on steel framing	The slab and deck must work together structurally
Form deck	0.6″, 1.0″, 1.5″	Permanent form for concrete	The slab carries its own reinforcing
Accessories	Acoustic batting, foam closures, cell/end closures, pour stops, sump pans	Finishing the deck system	Every job, matched to the deck profile
Crimping tool rental	Side lap crimpers	Side lap attachment	Your spec calls for crimped side laps

Roof Deck Products

Steel roof deck supports the insulation and membrane on low-slope commercial buildings. It spans between steel joists and, when fastened correctly, braces the building against wind and seismic forces as a diaphragm.

We carry the profiles contractors ask for most:

Type B (wide rib): The workhorse. B deck is 1.5″ deep with ribs at 6″ on center and a 36″ cover width. It shows up on warehouses, retail, schools, and mezzanines.
Type F (intermediate rib): Common on older buildings and in repair work. When you replace a section, matching the existing profile matters because different profiles do not interlock.
Type A (narrow rib): Narrow flute openings support thinner insulation boards.
Type N (deep rib): At 3″ deep, N deck spans farther, which can mean fewer joists and more open interiors.
1″ deck (C deck): A shallow profile for short spans and special uses like venting or acoustic applications.

Roof deck comes in several gauges and finishes, including galvanized and painted. The engineer of record selects profile, gauge, and finish from the manufacturer’s load tables.

Composite Floor Deck

Our composite deck options come in 1.5″, 2.0″, and 3.0″ depths. Composite deck has embossments rolled into the webs that lock into the concrete once it cures. The steel then acts as the slab’s bottom reinforcement, so deck and concrete carry load together.

Pick the depth based on beam spacing and loads:

5″ composite: Shorter spans and lighter slabs
0″ composite: A common middle option for many commercial floors
0″ composite: Longer spans between beams and heavier floor loads

Composite deck is typically specified galvanized because it lives in contact with concrete for the life of the building.

Form Deck

Form deck is a permanent steel form for concrete. We carry 0.6″, 1.0″, and 1.5″ profiles. Unlike composite deck, form deck does not rely on bonding with the slab. The concrete carries its own reinforcement, and the deck mainly holds the wet concrete and construction loads during the pour.

Form deck is a good fit for:

Mezzanines and platforms with thinner slabs
Stair landings and pan fills
Residential and light commercial concrete floors on steel framing
Short spans where composite action is not needed

Metal Deck Accessories

The deck is only part of the system. Our accessories close the gaps, contain the concrete, and finish the details:

Acoustic batting fills perforated deck ribs to absorb sound and add a bit of insulation value
Foam closures seal the rib openings at eaves, ridges, and walls against air, water, and pests
Cell and end closures close off the open ends of deck flutes at edges and openings
Pour stops form the edge of a concrete slab at the slab perimeter and openings
Sump pans create recessed drain locations in a steel roof deck

Order accessories with your deck so the profiles match and everything arrives together.

Crimping Tool Rental

Some specifications call for crimped (button punched or crimped) side laps instead of screws or welds. Buying a crimper for one job rarely makes sense, so we rent crimping tools to contractors who need them for a project. Ask about availability when you place your deck order.

How to Choose the Right Metal Deck Product

Start with the drawings. The structural sheets and deck specification section should spell out most of what you need. If something is missing, ask the engineer of record rather than guessing.

Identify the application. Roof, composite floor, or form deck.
Confirm the profile and depth. For repairs, measure the existing deck and match it.
Confirm the gauge. Common gauges are 22, 20, 18, and 16. Lower numbers are thicker.
Confirm the finish. Galvanized (G60 or G90), painted, or uncoated per spec.
Set the lengths. Cut-to-order lengths reduce waste and field cutting.
List the accessories. Closures, pour stops, sump pans, acoustic batting.
Check attachment requirements. Note if you need crimped side laps and a tool rental.

For design background, the Steel Deck Institute publishes the standards most deck specs reference, and AISC is a strong resource on the steel framing the deck sits on.

What metal deck products does Keystar carry?

We carry roof deck (Type A, F, B, N, and 1″ deck), composite floor deck in 1.5″, 2.0″, and 3.0″ depths, form deck in 0.6″, 1.0″, and 1.5″ profiles, deck accessories, and crimping tool rentals.

What is the difference between roof deck, composite deck, and form deck?

Roof deck supports insulation and a roof membrane. Composite deck bonds with concrete to act as slab reinforcement. Form deck is a permanent form for concrete that carries its own reinforcement.

Can I get metal deck cut to length?

Yes. We cut roof, composite, and form deck to order so sheets arrive at the lengths your layout needs.

What accessories do I need with steel deck?

Most jobs need some combination of foam closures, cell or end closures, pour stops, sump pans, and acoustic batting. Your drawings and specification list what the project requires.
