Galvanized Steel Construction 3/8 Inch Hi Rib Metal Lath With Paper For Wall Sheathing
WSFIVIN elevates structural integrity and moisture control with our galvanized Hi-Rib Metal Lath—a unified solution engineered for high-performance wall sheathing. Featuring 3/8-inch corrosion-resistant ribs factory-bonded to heavyweight kraft paper, this system delivers triple-layer defense: enhanced plaster adhesion, ASTM E96-compliant vapor diffusion, and seismic-grade reinforcement in a single install. Eliminate multiple trades with lath that doubles as a drainage plane, cutting installation steps by 60% compared to traditional felt-and-mesh methods. Precisely engineered for load-bearing stability, the deep-rib profile locks plaster into structural substrates while accommodating thermal movement in climates from Alaska’s freeze-thaw cycles to Arizona’s desert heat, guaranteeing crack-resistant finishes for decades.
Robust Engineering for Demanding Structures
Two critical innovations redefine durability:
- G-90 Galvanized Fortification: 20-gauge zinc-coated steel ribs exceed ASTM A653 standards, resisting alkali corrosion from stucco/plaster mixes and extending service life in coastal and industrial zones.
- Optimized Paper Integration: Non-tear paper backing bonds seamlessly to sheathing via standard staples, creating an immediate moisture barrier that blocks bulk water while permitting vapor escape—no separate house wrap required.
- Rib Geometry Intelligence: The 3/8-inch Hi-Rib depth maximizes cementitious material penetration (+40% vs. low-rib lath), preventing delamination in high-wind regions.
North American Sheathing Applications: Engineered for Code Compliance
Precision-tested for continent-specific demands:
- Exterior Stucco Cladding: Paper-backed lath meets IBC drainage plane mandates for wood/steel framing in Vancouver’s rain belts and Florida hurricane zones, preventing rot and mold ingress.
- Interior Partition Walls: Single-step application accelerates hotel/hospital builds across Chicago and Toronto—ribs bridge gypsum board joints to eliminate cracking at stress points.
- Fire-Rated Assemblies: Integrates with Type X plaster for 1-hour ASTM E119-rated corridors in NYC high-rises.
- Seismic Retrofitting: Rib flexibility accommodates structural shifts in California retrofit projects without compromising shear strength.
- Historic Masonry Reinforcement: Lightweight sheets adhere to irregular brick substrates in Boston brownstones, eliminating invasive anchoring.
- Contractor & Distributor Value: Profit Through Precision
WSFIVIN empowers wall sheathing specialists, stucco contractors, and building-supply networks with turnkey solutions exceeding ASTM C1063/C847 benchmarks. Drive ROI through: - Labor Reduction: Paper backing installs 3x faster than layered systems—staple directly to OSB/plywood sheathing without wraps or tapes.
- Zero-Waste Logistics: Pre-cut 27"x97" sheets align with 24-inch stud spacing; palletized shipments (400% denser than rolls) reduce freight costs for Midwest distributors.
- Custom Integration: Order factory-attached corner beads or control joints for seamless transitions.
- Code Confidence: Documentation packages include ASTM compliance reports for permit approvals coast-to-coast.

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.
