Rigid Rib Support Expanded Diamond Metal Lath For High Load Plaster Applications

Rigid Rib Support Diamond Metal Lath For High Load Plaster Applications

Featuring 3D-ribbed V-bend reinforcements at 6" centers, this heavy-gauge lath withstands industrial plaster loads exceeding 500 lb/ft²—ideal for sculptural precast façades, historic restoration, and structural stone veneer assemblies demanding zero substrate deflection. Its proprietary open-web matrix embeds deeply into thick mortar beds while self-leveling channels prevent aggregate bridging with coarse sand/cement mixes up to 3" thickness. Certified under ASTM E119 for 2-hour fire endurance when paired with Type X gypsum plasters, the electro-galvanized TRX-45 alloy resists alkaline spray exposure in parking garages and marine environments where traditional lath experiences compressive buckling.

Design-build firms handling museum installations and seismic-retrofit contractors deploy this system for cathedral ceiling renovations with existing timber purlins, where the interlocked ribs transfer shear loads without auxiliary framing. Rapid-clip attachment slashes installation duration by 55% versus welded methods during hospital tower expansions, with UL-classified acoustic damping properties blocking 42 STC noise flanking in multifamily partitions. Access job-specific rib-spacing calculators for terra cotta cladding or request thermographic mapping for cold-joint detection—reinforced by delamination-free warranties covering 300+ freeze-thaw cycles as documented per ASTM E2273 accelerated weathering protocols.
