Corrugated High-Rib Lath ASTM-A641 Galvanized

Structural Integrity Meets Advanced Corrosion Resistance

WSFIVIN’s Corrugated High-Rib Lath pairs ASTM-A641 galvanized steel with precision-engineered ribs, delivering 2.3x greater load capacity than standard lath systems. The 4mm deep corrugated ribs create interlocking joints for 750kg/m² vertical load ratings, ideal for heavy-duty construction applications.

Certified Technical Excellence

• ASTM-A641 Compliance: Class 3 galvanized coating ensures 5,000+ hour salt spray resistance
• High Tensile Strength: 550 MPa yield strength exceeds structural lath requirements
• Optimized Rib Geometry: 38° angular ribs prevent plaster slippage while allowing 30% faster installation

Core Applications

• Concrete Construction Joints: Creates permanent formwork for structural continuity
• Commercial Partitions: Supports multi-layer plaster assembly in 24” framing systems
• Infrastructure Fireproofing: UL-certified 4-hour fire resistance for steel columns/beams

Installation Advantages

• Dual-purpose design combines structural reinforcement and plaster keying
• Pre-punched alignment holes simplify fastening to steel studs
• Compatible with spray-applied and hand-troweled plaster systems

Quality Assurance

• Batch-tested for ASTM-A641 zinc coating adherence
• ISO 1461-certified hot-dip galvanization process

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.
