Gauge
Gauge | Bare Steel Thickness (inches) | Weight (lbs/sq ft) | Typical Applications | Manual sort |
|---|---|---|---|---|
22 | 0.0295 | 1.6 | Light-duty roofing and small spans. | 5 |
20 | 0.0358 | 2 | Medium spans, roofing, and siding. | 8 |
18 | 0.0474 | 2.6 | Heavy-duty applications | o |
16 | 0.0598 | 3 | Heavy load spans | q |
The Type B Vented Deck is available in gauges 22, 20, and 18, offering different thicknesses and load capacities to meet specific project needs. Lighter gauges (22 and 20) are cost-effective and ideal for shorter spans, while thicker gauge (18) provide greater structural strength, supporting longer spans and heavier loads. The perforated design enhances the bond between LWIC and the deck, ensuring proper adhesion and curing in insulated concrete applications.
Finish
Finish Type | Details |
|---|---|
Galvanized G60 | Zinc coating of 0.6 oz/ft². Recommended for general environments. |
Galvanized G90 | Zinc coating of 0.9 oz/ft². Ideal for highly corrosive environments. |
Prime-Painted | Provides a base coat for additional protection or paint adhesion. |
Bare Steel | Unfinished; typically for indoor use or controlled environments. |
To ensure durability and long-term performance, the Type B Vented Deck comes in galvanized (G60 and G90) and prime-painted finishes. Galvanized coatings offer corrosion resistance, with G90 providing extra protection for highly corrosive environments. The prime-painted option adds a protective base coat, ideal for projects requiring additional coatings. These finishes extend the deck’s lifespan while ensuring optimal performance in LWIC applications.
Applications of 1.5” Type B Vented Metal Decking Growth
Perfect for lightweight insulated concrete (LWIC) systems, the 1.5" Type B Vented Deck features perforations that enhance concrete adhesion and curing. Its design allows trapped moisture to escape during the curing process, preventing condensation and ensuring long-term durability.
Lightweight Concrete Systems
Ideal for composite slabs in LWIC systems, the perforations improve concrete bonding by allowing moisture to escape during curing. This prevents trapped condensation, enhances structural integrity, and ensures a durable insulated concrete system.
Moisture-Controlled Roof Assemblies
Designed for lightweight insulated concrete (LWIC) applications, the perforated profile improves concrete adhesion and curing. By allowing moisture release during the curing process, it enhances long-term insulation performance and prevents structural degradation in humid environments.
The 1.5" Type B Vented deck is crafted to align with industry-leading standards, ensuring reliability, durability, and performance for your projects.
Compliance with Standards
SDI (Steel Deck Institute): The 1.5" B Vented deck complies with SDI specifications, ensuring high standards for design and performance.
-
What gauge is most commonly used for Type B decking?20 gauge is generally the most common for Type B decking due to its balance of cost and strength for typical applications. However, project-specific requirements can necessitate other gauges.
-
What is the difference between G60 and G90 galvanized finishes?The difference between G60 and G90 galvanized steel is the amount of zinc coating applied for corrosion protection. G60 has a coating of 0.60 oz/ft² (183 g/m²), while G90 has 0.90 oz/ft² (275 g/m²), providing 50% more zinc and greater resistance to corrosion G60 is suitable for indoor applications or low-moisture environments, such as HVAC, interior metal structures, and construction panels. In contrast, G90 offers superior protection and is ideal for outdoor use, roofing, steel decking, and structures exposed to weather, humidity, or corrosive conditions. If the application requires higher durability and corrosion resistance, G90 is the best choice. However, if moisture exposure is minimal and cost efficiency is a priority, G60 may be sufficient.
-
What are the maximum spans for the 1.5" Type B deck?Maximum spans depend on the gauge, span type, and load requirements. For example, 22-gauge decks can span up to 8 feet under multiple spans, while 16-gauge decks can span up to 14 feet. Always consult load tables for precise details.
-
Can 1.5" Type B metal decking be customized for specific projects?Yes, the deck can be customized in terms of gauge, finish, and length. Custom lengths are cut to suit project needs, reducing waste and optimizing installation efficiency.
-
Does 1.5" Type B metal decking meet industry standards?Absolutely. It complies with Steel Deck Institute (SDI) standards and American Iron and Steel Institute (AISI) design guidelines, ensuring quality, safety, and compatibility with construction codes.
