Product Specification

Stucco Wall Expanded Corner Bead With Strong Corner Reinforcement

WSFIVIN's Stucco Wall Corner Bead redefines structural resilience with military-grade reinforcement specifically tailored for high-impact stucco applications. Featuring diamond-expanded steel core and 1 1/4" reinforced wings, it delivers 40% superior crack resistance in extreme heat cycles and seismic shifts—verified per ASTM E119 standards. Pre-punched FastFlex™ flanges enable self-aligning installation on warped masonry or curved walls, slashing labor time by 30%. Our proprietary AquaShield™ nano-ceramic zinc coating (200g/m²) provides lifetime rust immunity against coastal salt spray, acid rain, and freeze-thaw degradation. Available in pre-cut lengths (8’–10’) or custom angles up to 140°, this bead ensures flawless corners in demanding climates from Arizona desert sun to Canadian winters.

Robust Architecture Meets Precision Design
Forged from 0.45mm ASTM A653-compliant galvanized steel, this bead withstands 15J impacts without deformation—ideal for high-traffic zones. Its diamond-expanded core drives triple-action stucco keying, creating a 60% deeper mechanical bond than traditional units (ASTM C1064 certified). Reinforced wing edges incorporate laser-etched MicroGrip™ striations, eliminating plaster slippage and preventing "telegraphing" defects. Flexible flange geometry adapts to ±22° substrate variations using wave-rib reinforcement, while featherlight construction (0.8 lbs/ft)

reduces installer strain on multi-story builds.

Dominating North America's Most Demanding Stucco Scenarios

Hurricane-Ready Coastal Fortresses: Arm Miami luxury villas or Seattle heritage facades against 150mph winds; our zinc-armored wings block moisture intrusion and efflorescence.

Commercial Brutality Zones: Endure cart collisions in Atlanta airport corridors or chemical exposure in Midwest refineries—non-corrosive integrity withstands alkaline-rich stucco mixes.

Seismic Retrofitting: Secure California schools or Vancouver condos; flex flanges absorb structural drift, preventing joint failures in Zone 4 seismic areas.

Fire-Resistive Assemblies: Achieve UL-certified ASTM E119 90-minute ratings with integrated fireproofing adherence—critical for Chicago skyscraper cores.

Historic Renovations: Restore New Orleans’ French Quarter without disruptive reconstruction; bead conforms to undulating masonry with precision-trimmed edges.

The Stucco Specialist’s Ultimate Edge
Crafted for professional stucco crews, architectural contractors, and building material distributors, WSFIVIN delivers unmatched ASTM compliance and logistical agility. Every shipment includes blockchain-tracked mill certs for ASTM A653 (rust resistance) and ASTM C841 (stucco adhesion). Customization is our hallmark: request RFID-tagged bundles, field-tested zinc coatings (250g/m² for coastal projects), or custom lengths up to 16’. With same-day palletization from our Montreal and Dallas hubs, 48-hour emergency dispatch, and 10,000+ sq ft custom order capacity, we ensure you never compromise corners for deadlines.
