ASTM C1063 Certified Hi-Rib Lath with 3/8" Vertical Ridges

Code-Compliant Structural Support for Extended Framing Systems

WSFIVIN’s ASTM C1063-Certified Hi-Rib Lath features seven 3/8" vertical V-ribs1 spaced at 3-7/8" intervals, engineered to meet strict ASTM C1063 requirements for 24" on-center ceiling framing. Fabricated from G60 galvanized steel compliant with ASTM C8473, this lath maintains structural integrity under 500kg/m² loads while enabling direct plaster application with no minimum thickness restrictions.

Technical Features

1.Structural Superiority:

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.
