Rigid Support Expanded Stucco Mesh Lath For Three Coat Stucco System

Rigid Support Expanded Metal Lath Ideal For Three Coat Stucco System

Featuring proprietary diamond-core stabilizing nodes interlocked with expanded zinc-alloyed steel apertures, this structural lath delivers a 40% rigidity gain over conventional meshes to prevent stucco deflection in seismic zones or high-wind regions. Its 0.072-inch rib depth exceeds ASTM A653 requirements, generating exceptional plaster key height while engineered weep gaps maintain vapor diffusion—critical for managing freeze-thaw stresses across Canadian shield regions or coastal mid-rises. Installed vertically over sheathing per ASTM C1063, the double-galvanized G235 substrate resists salt corrosion in hurricane-prone condominiums while enabling single-pass application behind polymer-modified base coats.

Commercial stucco contractors specifying Class I fire-rated assemblies deploy this solution for its pre-notched lap seams that accelerate installation by 30% over woven laths, with patent-pending standoff clips maintaining drainage cavity integrity in Continuous Insulation (ci) systems. Third-party testing confirms zero substrate contact behind 1.5” foam insulation per IBC Section 1405.6, while integrated seismic clips exceed CBC Section 1604.8 requirements for Zone 4 hospital retrofits. Access ICC-ES wind-uplift certifications for 150 mph exposure B regions and leverage exclusive 25-year dent-resistance warranties validated through 500 accelerated salt-spray cycles per ASTM B117.
