1.5" Type B Roof Deck

Looking for a 1.5" Type B metal deck supplier for projects in Tallahassee? This roof deck delivers strong structural performance and goes in quickly. It comes in 22 GA to 16 GA, meets SDI and ANSI standards, and ships in galvanized finishes such as G60 and G90 for added durability and corrosion resistance on Tallahassee roofing jobs.

Dimensions and profile

1.5" Type B Roof Deck profile dimensions

PropertyDimension
Profile Depth1.5 inches
Coverage Width36 inches
Rib Spacing6 inches (center to center)
Rib Height1.5 inches

With a 1.5 inch rib depth and a 36 inch standard coverage width, the 1.5" Type B metal deck is structurally efficient for roofing and flooring. The 6 inch rib spacing (center to center) and 39 inch overall material width allow secure overlaps and strong composite action when concrete slabs are added. Strength is maximized and weight is minimized, which keeps the deck durable and versatile on all sorts of construction jobs.

Gauges and thicknesses

1.5" Type B Roof Deck gauges

200.03582Medium spans, roofing, and siding.
180.04742.6Heavy-duty applications.
160.05983Heavy load spans.

There are four gauges to choose from for Type B deck: 22, 20, 18, and 16. Each has different thickness and load capacity, so you can fit the deck to the project. Light and cost-effective, 22 and 20 gauge are best on shorter spans and lighter loads. Stronger 18 and 16 gauge carry longer spans and heavier loads, which makes them ideal for demanding applications.

Finishes and coatings

FinishDetails
Galvanized G60Zinc coating of 0.6 oz/ft². Recommended for general environments.
Galvanized G90Zinc coating of 0.9 oz/ft². Ideal for highly corrosive environments.
Prime-PaintedProvides a base coat for additional protection or paint adhesion.
Bare SteelUnfinished; typically for indoor use or controlled environments.

Type B deck is produced with several finishes for long service life, including galvanized (G60 and G90) and prime-painted. Galvanizing resists corrosion well, and G90 carries a heavier zinc coating for settings with more moisture or chemical exposure. Prime paint supplies a base coat for projects that will receive additional paint or coatings.

Material and finish options

Our steel options cover 33 KSI, 40 KSI, 50 KSI, and 80 KSI grades, each engineered for specific structural requirements and a sound mix of strength and flexibility. Finishes in galvanized (G60/G90) and prime-painted conform to ASTM A653 specifications to resist corrosion.

Custom lengths

Deck lengths start at 6′-0″ for compact jobs and run up to 40′-0″ for large structures, so we can fit nearly any layout in Tallahassee. Cutting to your custom length keeps waste low and the deck fitting properly on site.

1.5" Type B Roof Deck features

Lightweight yet durable, our 1.5" Type B metal deck also brings fire resistance and a sustainable design. It is a practical, eco-friendly pick for short-span commercial projects.

High Strength-to-Weight Ratio

Quality and code compliance are backed by Steel Deck Institute (SDI) and ANSI guidelines.

Wide Gauge Range

The 22, 20, 18, and 16 gauge options let you match the deck to the load-bearing needs and demands of the project.

Installation and connections

Installation practices

  • Place the deck perpendicular to the supports.
  • Secure the deck to each support using puddle welds or TEK screws.
  • Overlap the sidelaps, then screw them down at 12" o.c.

Fasteners and attachments

  • 5/8" Diameter Puddle Welds
  • #10 TEK screws at 6" o.c. on edges, and 12" o.c. for sidelaps
  • Sidelaps attached using #10 TEK screws at 12" o.c.

Applications

Roof Deck Applications

Roof Deck Applications

Where commercial and industrial roofs need strength and durability, Type B is a common pick. It supports roofing insulation systems and suits both vented and non-vented roofing.

Hybrid Structural-Ceiling Systems

Hybrid Structural-Ceiling Systems

In architectural spaces, Type B decking can double as an exposed ceiling. It supplies structural strength and a clean finish, and it reduces added materials and installation time.

Standards and product documentation

The 1.5" Type B deck meets SDI (Steel Deck Institute) specifications, which sets a high bar for design and performance on Tallahassee projects.

1.5" Type B Roof Deck questions

What gauge do most buyers choose for Type B decking?

20 gauge is typically the most common, because it offers a good balance of cost and strength for ordinary applications. Some projects need a different gauge based on their requirements.

What separates G60 from G90 galvanized finishes?

The coating on G60 is 0.60 oz/ft² versus 0.90 oz/ft² on G90. That makes G90 50% heavier in zinc and more corrosion resistant. G60 works for indoor applications or low-moisture environments, while G90 is better for outdoor use, roofing, steel decking, and structures facing weather, humidity, or corrosive conditions.

What are the maximum spans of the 1.5" Type B deck?

The answer depends on gauge, span type, and loading. For instance, 22-gauge deck spans up to 8 feet in multiple spans, and 16-gauge deck spans up to 14 feet. For exact numbers, refer to the load tables.

Can I get 1.5" Type B metal decking customized for my Tallahassee project?

Yes, gauge, finish, and length are all customizable. Lengths are cut to project needs, so there is less waste and installation goes more efficiently.

Do 1.5" Type B metal decking products meet industry standards?

Yes, they do. The deck follows Steel Deck Institute (SDI) standards and American Iron and Steel Institute (AISI) design guidelines, ensuring quality, safety, and compatibility with construction codes.

3" Type N Roof Deck

Roof applications often call for 3" Type N metal deck, thanks to its long-span capability and structural strength. A 3 inch deep profile and gauges from 22 GA to 16 GA let it flex across roofing projects in Tallahassee. It complies with SDI and ANSI standards, with galvanized finishes like G60 and G90 available.

Dimensions and profile

Applications

Lightweight Concrete Systems

Lightweight Concrete Systems

LWIC composite slabs are a natural fit. Perforations let moisture escape as the concrete cures, improving bonding, preventing trapped condensation, and strengthening a durable insulated concrete system.

Moisture-Controlled Roof Assemblies

Moisture-Controlled Roof Assemblies

For lightweight insulated concrete (LWIC) applications, the perforated profile makes concrete adhesion and curing better. Moisture escapes during curing, so long-term insulation performance improves and structural degradation is prevented in humid environments.

Standards and product documentation

SDI (Steel Deck Institute) specifications are met by the 1.5" B Vented deck, ensuring high standards for design and performance on Tallahassee jobs.

1.5" Type B Vented Roof Deck questions

Why does the vented Type B deck have perforations?

They improve airflow and moisture control, stop condensation from building up, and improve adhesion in lightweight concrete applications.

How does vented Type B deck help composite systems in Tallahassee?

Small perforations strengthen the bond between deck and concrete for stronger composite action. They also let moisture escape, which lowers the chance of water getting trapped.

Can vented Type B deck be used in every roofing application?

Yes, though it helps most in moisture-sensitive settings such as vented roofing systems, where air circulation protects insulation from degradation and corrosion.

Which finishes come on the vented Type B deck?

Galvanized (G60/G90) provides corrosion resistance, and prime-painted finishes provide protection and work with additional coatings.

Do the perforations reduce the structural strength of the vented Type B deck?

No. They are placed strategically so the deck keeps its load capacity and still delivers ventilation benefits for specific applications.
