Type B metal decking typically features a 1.5-inch rib profile and is widely recognized for its use in roof systems. However, in certain floor and mezzanine applications, Type B deck can be a practical, cost-effective option. Below are seven ways builders and facility owners can leverage Type B deck for flooring projects.
1. Light-Duty Mezzanines and Platforms
Ideal for: Warehouses, manufacturing facilities, and retail backrooms needing extra storage or elevated workspace.
Key Benefit: Type B metal deck is lightweight yet sufficiently robust to handle moderate foot traffic and shelving loads.
Why It Works: Its 1.5-inch corrugated profile provides better load distribution than flat sheets, reducing deflection while minimizing additional structural support.
2. Equipment Platforms and Catwalks
Ideal for: Industrial sites requiring raised walkways or maintenance platforms around machinery or production lines.
Key Benefit: Provides a slip-resistant surface when paired with the right coating or top layer (e.g., diamond plate).
Why It Works: The corrugated ribs offer structural integrity for narrower spans, making it a go-to for catwalks and platforms that don’t require full composite floor decking.
3. Temporary Construction Floors
Ideal for: Projects in high-rise or multi-level construction where intermediate decking is needed during building phases.
Key Benefit: Serves as a temporary floor for workers, equipment, or materials, aiding in a smoother and safer build process.
Why It Works: Type B deck installs quickly and can be easily dismantled or integrated into permanent floors if designed accordingly.
4. Short-Span Composite Floor Systems (Non-Traditional)
Ideal for: Light commercial or smaller structures that won’t require heavy floor loads.
Key Benefit: When used with shear studs and a concrete topping, Type B deck can function as a composite slab, increasing stiffness without excessive weight.
Why It Works: Though more commonly associated with dedicated composite decks, Type B can handle moderate floor loads if properly engineered, making it a viable option for certain low-to-mid-rise buildings.
5. Retail Platforms and Storage Areas
Ideal for: Back-of-house inventory areas, extended storage racks, or elevated retail displays.
Key Benefit: Easy to install and can be quickly modified to accommodate changing layouts or expansions.
Why It Works: The ribbed profile enhances load distribution, supporting point loads from shelving units and storage racks.
6. Renovation and Retrofit Flooring
Ideal for: Older buildings where existing floors need reinforcement or partial replacement.
Key Benefit: Type B’s lightweight design minimizes the need for added structural modifications.
Why It Works: It can be installed over or alongside older materials to upgrade load capacity without significant changes to the building’s framework.
7. Elevated Office Spaces Within Industrial Facilities
Ideal for: Creating a semi-permanent office or break room above factory floors to maximize usable space.
Key Benefit: Offers a stable floor surface suitable for light partitions, furniture, and foot traffic.
Why It Works: Allows for efficient partitioning of large industrial spaces by taking advantage of vertical room for administrative or employee break areas.
Final Thoughts
Although Type B metal decking is most often associated with roofing, it can serve as a practical flooring solution in light-duty, short-span, or temporary scenarios. Its corrugated profile adds strength where it’s needed, while its relatively lightweight design simplifies installation and can reduce project costs. Whether you’re building a mezzanine, creating an elevated office space, or need a temporary construction floor, Type B deck may be a surprisingly versatile choice.
Always consult a licensed structural engineer or follow manufacturer guidelines to ensure that Type B decking meets the specific demands of your floor application. With the right design and installation, Type B can help you maximize space and efficiency in your next building project.
