Expanded Metal Corner Bead With Reinforced Edges 1-1/4" Flange Width

Expanded Metal Corner Bead with Reinforced Edges 1-1/4" Flange Width

WSFIVIN’s Expanded Metal Corner Bead redefines structural durability for stucco and plaster systems, merging military-grade corner protection with rapid installation for North America’s demanding construction timelines. Designed to outperform traditional plastic or paper-faced alternatives, this 1-1/4" flange width corner bead features diamond-expanded galvanized steel with laser-welded edge reinforcement—eliminating seam blowouts and anchoring base coats up to 1.5x deeper for crack resistance. Rigorously tested for impact resistance and ASTM C1063 compliance, it withstands jobsite abuse in high-traffic zones while its integrated weep holes prevent moisture entrapment behind finishes. Pre-tapered flanges seamlessly integrate with wood, metal, or masonry substrates, slashing labor time by 30% and delivering razor-sharp corners that endure coastal salt, freeze-thaw cycles, and seismic stress.

Robust Engineering for Uncompromising Performance
Crafted from 20-gauge hot-dip galvanized steel, our expanded core architecture enables maximum plaster key-through for unbreakable adhesion while remaining lightweight (20% lighter than solid beads). The patent-pending reinforced edges use continuous laser-welding to prevent flange distortion under heavy troweling, and the 1-1/4" width achieves 45% more fastener points versus standard 1" beads—critical for wind-uplift resistance in hurricane zones. Unique dimpled flanges enhance grip on uneven surfaces, and the angled weep channels ensure drainage without compromising fire ratings (ASTM E119). Unlike flimsy vinyl alternatives, this bead’s zinc-aluminum coating provides 1000-hour salt spray resistance (ASTM B117), guaranteeing decades of corrosion-free service.

Transformative Applications Across Building Types

• Commercial Edges: Reinforce retail entrances, hospital corridors, and school corners vulnerable to cart impacts.
• Coastal & Industrial Sites: Defend against salt corrosion in Florida resorts or factory wear with zinc-aluminum fortification.
• Seismic & High-Wind Regions: Secure corners in California earthquake zones or Tornado Alley builds via extra-wide flange anchoring.
• Historic Restorations: Replicate crisp period profiles on heritage brick without invasive framing.
• Curved Architectural Features: Flexible expanded metal conforms to arched windows or radius walls without creasing.

The Contractor’s Ultimate Corner Solution
Engineered for stucco specialists, drywall contractors, and distributors, WSFIVIN’s corner bead delivers code-compliant reliability (ASTM C1063/C847) with bulk efficiency. Custom-cut lengths (8ft/10ft/12ft) reduce waste on complex facades, palletized shipping (200 units/pallet) ensures cost-effective logistics, and color-coding options streamline inventory management. Supported by 24/7 technical guidance and BIM-ready specs, we offer volume discounts and same-week prototyping for urgent projects—proving why Tier-1 builders trust our beads to eliminate callbacks and protect reputations from the ground up.

Expanded Corner Bead – Frequently Asked Questions
