Corrosion-Resistant G90 Self-Furring Metal Lath for Fireproofing Construction
Overview
WSFIVIN’s G90 Self-Furring Lath delivers unmatched corrosion resistance and fireproofing performance for critical infrastructure projects. Featuring a 90g/m² zinc coating** and 0.019in steel thickness, this lath meets UL fire-resistance ratings while exceeding ASTM A653 specifications for heavy-duty applications.
Key Features
1.G90 Galvanized Superiority
-3x thicker zinc layer (90g/m²) vs. standard G30 lath, ensuring 50+ years of service in corrosive environments like coastal plants and chemical facilities.
-ASTM B117-certified for 5,000+ hours of salt spray resistance.
2. Fireproofing Optimization
-Integrates seamlessly with 2-hour fire-rated plaster systems(ASTM E119).
-Self-furring 5/16” dimples** enhance plaster adhesion while maintaining critical air gaps for thermal regulation.
3. High-Load Capacity
-0.019in (22GA) steel core supports 200 PSI compressive loads in industrial ceilings and tunnels.
-Diamond mesh (5/8” x 5/8”) prevents crack propagation under seismic stress.
Applications
-Nuclear Facilities: Radiation-shielded wall assemblies.
-Oil Refineries: Fireproofing structural steel in explosive atmospheres.
-Underground Parking: Moisture-resistant ceilings with Class A fire rating.
-Tunnel Linings: Corrosion protection in high-humidity transit systems.
Service Advantages
-MOQ: 250 sheets | Custom paper-backing for 1-hour/2-hour fire ratings.
-Free ASTM/UL compliance documentation for LEED® projects.
