Summary
- Common gauges: 16, 18, 20, 22
- Use G90 or galvalume near coast
- We stock mill-certified Type B deck
At Miami Metal Deck we supply Type B metal deck gauges commonly stocked and specified by Florida suppliers and contractors. We focus on mill-certified material, corrosion-resistant coatings, and documented compliance with Florida Building Code to ensure your project meets performance and inspection requirements.
Common Gauges Stocked in Florida
Most Florida suppliers and contractors commonly stock Type B metal deck in 16, 18, 20, and 22 gauge. 16 gauge is used for heavy live loads and longer spans; 18 gauge is the most frequently specified for general commercial floors; 20 and 22 gauge are chosen for shorter spans or lighter non-composite applications. Thicker 14 or 12 gauge panels are available for specialty heavy-load or long-span requirements.
Specify the coating and corrosion class along with gauge: G60 and G90 zinc galvanizing and AZ50/AZ55 galvalume are standard options. Near coastal Florida exposures specify G90 or galvalume for improved corrosion resistance. Materials typically conform to ASTM A653 for galvanized steel and ASTM A792 for galvalume where applicable.
How to Specify Gauge for Your Project
Choose gauge based on span tables, live loads, deck profile, composite topping thickness, and fire rating requirements. Coordinate with the structural engineer and reference manufacturer span tables. Miami Metal Deck provides span charts, shop drawings, and mill certificates to support submittals and code compliance.
Miami Metal Deck advantages include in-region inventory of common Type B gauges, fast lead times, mill-certified material, and proven experience with Florida coastal projects. We guarantee accurate gauge labeling and documentation to reduce inspection delays and project risk.
Coastal Corrosion and Coating Recommendations
For coastal projects prioritize corrosion protection: specify G90 galvanizing or AZ50/AZ55 galvalume and consider heavier gauges for extended service life. Use stainless or coated fasteners and provide separation from dissimilar metals to minimize galvanic corrosion in marine environments.
Typical availability: standard gauges often ready for immediate pickup or local delivery; custom and specialty gauges may require one to two week lead times. We offer cut-to-length, nested packs, and fabrication to match job sequencing and reduce onsite waste.
Code References and Best Practices
Reference the Florida Building Code, IBC, ASTM A653, ASTM A792, and Steel Deck Institute guidance when specifying Type B deck. Miami Metal Deck supplies mill certificates, material test reports, and documentation to demonstrate compliance and support inspections.
