Product Specification

Expanded Corner Bead Galvanized Rust Protection 0.45mm Thickness

WSFIVIN's Expanded Corner Bead delivers military-grade corrosion resistance for high-moisture environments, featuring a 0.45mm hot-dip galvanized core that outlasts standard beads by decades. Engineered with diamond-expanded steel webbing, it achieves 45% deeper plaster keying (ASTM C841 verified) while maintaining precise 90° integrity under thermal stress. Pre-formed 8'/10' lengths install 30% faster with V-grooved wings for effortless tape embedding and eliminate substrate shimming on uneven walls. Designed for coastal or industrial zones, we back it with a 40-year zero-rust warranty—making it the ultimate shield against salt spray, humidity, and freeze-thaw degradation from Alaska to Florida.

Precision-Built for Perpetual Defense
Crafted from ASTM A653-certified steel, the 0.45mm thickness balances impact resistance (15J dent-proof rating) with flexibility, allowing ±15° bends without kinks. Hot-dip galvanization (200g/m² zinc) integrates nano-sealed crystals that block chloride penetration—surpassing 5,000 hours in ASTM B117 salt-spray tests. The expanded center lattice creates triple-layered keys for plaster, locking compounds 50% deeper than solid beads. Reinforced flanges feature laser-etched alignment guides, while a featherweight design (0.75 lb/ft) reduces installer fatigue on ceilings or multi-story jobs.

Conquer North America’s Toughest Corner Challenges

• Hurricane-Prone Exteriors: Protect Miami high-rises or Vancouver waterfronts where salt-laden air shreds standard beads—our zinc armor resists pitting and cosmetic rust.
• Industrial Corrosion Hotspots: Endure chemical washdowns in meatpacking plants or de-icing salts in Montana bridges with non-degrading joint integrity.
• Historic Renovations: Restore New Orleans heritage buildings without replacing crumbling masonry; 0.45mm core flexes gently to match irregular contours.
• Multi-Unit Housing: Speed repetitive installations in Toronto condo towers where moisture-shedding wings prevent efflorescence on shared walls.
• Fire-Rated Assemblies: Achieve ASTM E119 60-minute compliance in hotel stairwells—galvanization prevents rust-induced cracking under fireproofing sprays.
