Supports 3-coat plaster systems up to 2" thick without sagging

2.Material Longevity:

G60 hot-dip galvanized coating resists corrosion for 30+ years

ASTM C847-compliant steel base (550MPa tensile strength)

Application Methodology

Column Encasement: Spirally wire-tied for uniform plaster distribution

Beam Protection: Ribs align perpendicular to steel members for load distribution

High-Rise Compliance: Meets IBC Section 715 for structural fireproofing

Installation Efficiency

Pre-punched alignment marks for 16" O.C. wire tying

Self-furring dimples maintain 1/4" plaster clearance

30% faster installation compared to welded mesh alternatives

Certifications & Compatibility

ASTM C1063 compliant for vertical applications

Compatible with all Type X gypsum plasters

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.
