Enhanced Keying Performance 3/8 Inch High Rib Metal Lath With Paper For 3 Coat Stucco System

Enhanced Keying Performance 3/8 Inch Hi Rib Metal Lath With Paper For 3 Coat Stucco System

WSFIVIN transforms stucco integrity with precision-engineered metal lath designed explicitly for high-performance 3-coat applications. Our patented 3/8-inch Hi-Rib profile amplifies mechanical keying by 50% versus standard lath, locking base coats into a unified tensile matrix that eliminates delamination risks. Factory-bonded heavyweight kraft paper integrates moisture diffusion (ASTM E96-compliant) and crack-arresting reinforcement in one step, replacing disjointed felt-and-lath sequences. Proven across Arizona’s thermal extremes and Quebec’s freeze-thaw cycles, the G-90 galvanized ribs ensure alkali-resistant stability for stucco systems demanding uncompromised adhesion—slashing callbacks while delivering architecturally flawless finishes.

Structural Synergy: Anatomy of a Superior Bond
Three pillars drive unparalleled stucco integration:

• Depth-Optimized Rib Geometry: 3/8-inch high ribs forge deep, uniform channels for cementitious penetration, creating a mechanical interlock that surpasses ASTM C1063 keying requirements.
• Vapor-Responsive Paper Backing: Non-tear kraft paper regulates moisture migration without impeding vapor escape, preventing efflorescence and substrate corrosion.
• Corrosion-Proof Endurance: Electroplated G-90 zinc (exceeding ASTM A653) withstands cement alkalinity for 40+ years—critical for coastal or industrial zones.

North American 3-Coat Mastery: From Suburbs to Skyscrapers
Validated solutions for continent-specific stucco challenges:

• Seismic-Resilient Cladding: Rib flexibility absorbs ground movement in California retrofits, maintaining stucco integrity atop wood/steel framing.
• Freeze-Thaw Defense: Thermal expansion slots in ribs prevent stress cracks across Chicago high-rises and Toronto townhomes.
• Moisture-Managed Substrates: Paper backing halts capillary action in Florida humidity, inhibiting mold in EIFS assemblies.
• High-Impact Commercial: 20-gauge ribs withstand jobsite abrasion for hospital façades and campus expansions.
• Historic Renovations: Lightweight sheets conform to irregular masonry in Boston brownstones without invasive anchors.

Stucco Specialists’ Edge: Speed, Compliance & Customization

WSFIVIN equips stucco contractors, building envelope teams, and architectural suppliers with systems engineered under ASTM C1063/C847 and C926. Dominate bids through:

• Labor Intelligence: Single-step lath-and-paper installation halves staging time versus layered methods—staple directly to sheathing.
• Zero-Waste Precuts: 27"x97" sheets align with 24-inch stud spacing; custom die-cuts available for arches or complex curves.
• Code Confidence: Documentation packages include IBC stucco assembly compliance for fast permitting from Seattle to Miami.
• Volume Economics: Palletized shipments (500 sheets/skid) trim freight costs 35% for Midwest distributors.
  One layer. One bond. One legacy.

FAQ

1. What is High Rib Lath used for?

High Rib Lath is designed for heavy-duty stucco, concrete, and plaster applications. It’s ideal for walls, ceilings, and formwork where superior reinforcement and mechanical keying are required.

2. Does your High Rib Lath meet U.S. and Canadian building codes?

Yes. Our product complies with ASTM C847 and is ICC-ES certified, ensuring it meets the structural and safety requirements of North American construction standards.

3. What makes High Rib Lath different from regular metal lath?

It features deep ribs and expanded metal openings for added stiffness and superior bonding. The ribbed profile provides strong support for thick plaster or concrete applications, even over wide spans.

4. What is the minimum order and lead time?

The MOQ is 2 pallets (total of 1,000 sheets, 500 sheets per pallet). Lead time is typically 15–20 working days, depending on order size and customization.

5. How is the product packaged for export?

We use sturdy palletized packaging for safe container shipping. Each pallet is tightly strapped and can be customized with waterproof wrap or branding labels as needed.
