Coating Options for Type B Metal Decks to Meet Florida Coastal Corrosion Requirements
We offer Type B metal decking for Florida coastal projects, providing certified coating selection, application, and inspection services that meet Florida Building Code corrosion requirements and ASTM/AAMA standards for long-term durability.
Summary
- Zinc or thermal spray for sacrificial protection
- AAMA 2605 and ASTM B117 testing
- Miami Metal Deck provides spec-grade coating solutions
Miami Metal Deck explains coating options for Type B metal deck installations along Florida coastlines so your project meets corrosion requirements and delivers long service life. You, your contractor, or architect will learn practical, code-aware choices that balance sacrificial and barrier protection, inspection needs, and long-term performance guarantees.
Why coastal corrosion compliance matters
Florida coastal conditions accelerate corrosion from salt spray, humidity, and wind-driven chloride. The Florida Building Code and industry standards require specified protection for exposed steel assemblies such as Type B metal deck to prevent premature failure, leaks, and warranty disputes. Selecting the right coating system reduces lifecycle costs, limits downtime, and ensures insurer and code acceptance.
Primary coating strategies include hot-dip galvanizing for sacrificial zinc protection; thermal spray aluminum or zinc for robust shop-applied metallurgical coatings; high-performance inorganic zinc primers as a sacrificial layer; epoxy primer combined with polyurethane, polysiloxane, or AAMA 2605 fluoropolymer topcoats for durable barrier systems; zinc-rich epoxy systems for field touch-ups; and specialty liquid-applied urethane or polyurea at seams and flashings. Fasteners, edge treatment, and compatible sealants are equally critical to system performance.
Performance, testing, and Florida Building Code considerations
Choose systems proven by ASTM and AAMA tests: ASTM B117 salt spray for comparative corrosion resistance, AAMA 2605 for high-performance organic coatings, and ASTM A123 or ASTM A153 guidance for galvanizing. For nearshore or open-ocean exposure specify higher-performance systems and verified lab data. Documented test results, specified film builds, and material data sheets help demonstrate compliance with Florida Building Code requirements for coastal applications.
Specification best practices: require SSPC-compliant surface preparation (SSPC-SP10 or equivalent near-white blast where practical), verification of anchor profile, specified dry film thickness ranges for each coat, shop-applied metallurgical coatings when possible, and qualified field touch-up procedures. Insist on compatible fasteners and pretreated penetrations to avoid galvanic corrosion and ensure continuous protection at seams and flanges.
Application, inspection, and warranties
Correct application includes cleaning and pretreatment, abrasive blasting or power tool cleaning per spec, primer application, intermediate coats if required, and high-performance topcoat application at specified ambient conditions and thickness. Use adhesion testing, holiday detection, and film-thickness verification as QA steps. For field repairs follow manufacturer-recommended prepatch, abrasive cleaning, and compatible hand-applied products.
Inspection and maintenance plans extend service life: scheduled visual inspections, targeted touch-ups, third-party salt-spray or adhesion testing for disputed areas, and documented maintenance logs. Many manufacturers provide warranties tied to specified systems and certified applicators; Miami Metal Deck provides compliance documentation, third-party testing coordination, and project-specific warranty support to help protect your investment.
