Corrosion-Resistant Dimpled Metal Lath for Plaster Reinforcement

Corrosion-Resistant Dimpled Metal Lath for Plaster Reinforcement

Dimpled Metal Lath is a reinforced plaster base made from high-quality galvanized steel with a unique dimpled surface design. The raised dimples create a superior mechanical bond between the plaster and substrate, improving adhesion and reducing the risk of cracking or delamination.

With a G60 or G90 hot-dip galvanized coating, this lath provides excellent resistance to corrosion and oxidation, even in humid, coastal, or industrial environments. The open expanded mesh structure allows mortar to interlock securely while maintaining uniform plaster thickness and enhancing load-bearing performance.

Ideal for stucco, cement plaster, fireproofing, and wall insulation systems, this durable and lightweight material simplifies installation and ensures long-term structural stability.

Features & Benefits

• Corrosion Resistant: Heavy zinc coating (G60/G90) ensures long-lasting durability in harsh environments.

• Enhanced Bonding: Dimpled pattern provides strong plaster adhesion and consistent surface finish.

• High Strength: Expanded steel mesh resists deformation and supports thick plaster layers.

• Easy Installation: Lightweight, flexible, and easy to cut or shape on-site.

• Wide Application: Suitable for masonry, wood, or metal framing systems.

 FAQ

1. What is dimpled metal lath used for?

It is used as a superior plaster base in stucco and masonry systems. The dimples create an air gap that enhances mechanical bonding and moisture drainage, improving overall system durability.

2. Does it meet North American construction standards?

Yes. Our dimpled lath is manufactured in compliance with ASTM C847 and is suitable for use in both U.S. and Canadian building systems. ICC-ES certification is also available for select models.

3. What are the key benefits of the dimpled design?

The dimpled structure increases rigidity, improves plaster grip, allows better keying of cementitious materials, and promotes drainage behind the lath—ideal for EIFS and moisture-managed walls.

4. What is your minimum order quantity and lead time?

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

5. How do you package the product for export?

We use durable palletized packaging, suitable for container shipping. Custom labeling and weather-resistant wrapping are available on request to meet project or distributor needs.
