ASTM C1063 / EN 14353 Expanded Corner Bead Flexible Flange Design 1 1/4 Inch

Product Specification

Expanded Corner Bead Flexible Flange Design 1 1/4 Inch Wing Width

WSFIVIN redefines corner durability with our groundbreaking Expanded Corner Bead, engineered to eliminate cracking and delamination in high-stress environments. Featuring a revolutionary flexible flange design with 1 1/4" wings, it delivers 50% faster installation and perfect alignment for curved walls or uneven substrates—no shimming required. Hot-dip galvanized steel core ensures zero corrosion even in coastal salt spray, while the diamond-expanded center provides 40% stronger plaster adhesion than standard beads (ASTM C841 tested). Pre-cut 8’/10’ lengths or custom angles (90°–135°) adapt to complex architectural joints, accelerating renovation projects and cutting onsite waste by 30%. Trusted by seismic-zone contractors for its ability to withstand impacts and thermal shifts without failure.

Engineered Resilience in Every Detail
At its core, the 0.45mm galvanized steel (ASTM A653 compliant) ensures a 30-year lifespan against rust, moisture, and freeze-thaw cycles in harsh climates. The flexible flange incorporates a patented "FlexTech" wave pattern, allowing ±20° angular adjustments without creasing—securing flawless alignment on warped studs or historic masonry. Expanded metal webbing provides deep 3D keying for plaster/stucco, quadrupling surface contact versus solid beads. Weighing just 0.8 lbs/ft, the 1 1/4" wings offer optimal overlap for seamless tape embedding, while bead-reinforced edges resist job-site damage during transit or handling.

Cornerstone Applications for North American Structures

• Exterior Stucco Fortification: Defend Miami condos or Vancouver luxury homes against hurricane winds and cracking—moisture-wicking wings prevent efflorescence in rain-soaked or arid Southwest climates.
• High-Traffic Interiors: Create bulletproof corners in Las Vegas casinos or Toronto hospitals, withstanding cart impacts while maintaining crisp lines through humidity fluctuations.
• Seismic & Retrofit Projects: Secure century-old Boston brickwork or California schools; flexible flanges absorb structural movement, eliminating stress cracks in seismic zones up to Zone 4.
• Tilt-Up/Warehouse Efficiency: Accelerate industrial builds with bead-trimmed corners that integrate flush with insulation panels, reducing foam overcut by 65% during concrete pours.
• Fire-Rated Assemblies: Pass ASTM E119 90-minute ratings when paired with fireproofing compounds—essential for NYC high-rise cores and elevator shafts.

The Contractor’s Precision Edge Solution
Tailored for drywall specialists, stucco crews, and national distributors, WSFIVIN’s corner bead merges ASTM compliance with unrivaled versatility. Every shipment includes blockchain-validated mill certs for ASTM A653 (corrosion resistance) and ASTM C1064 (adhesion strength), removing inspection bottlenecks. Customize on demand: order RFID-tagged bundles for site inventory control, specify UL-approved configurations, or request hurricane-grade zinc coatings (200 g/m²) for Gulf Coast compliance. Our Chicago and Vancouver warehouses offer 48-hour just-in-time delivery, while bulk pallets include free Revit/BIM support and 25+ length profiles—proving why top-tier builders partner with us for mission-critical corners.
