Enhanced-Bond Dimpled Metal Lath for Stucco and Plaster Systems
Dimpled Metal Lath is a specially engineered expanded metal lath designed to provide superior bonding strength between plaster, stucco, and the substrate surface. The unique dimpled embossing pattern creates raised contact points, allowing for deeper mortar penetration and mechanical interlock — ensuring a stronger, longer-lasting bond for all cementitious coatings.
Manufactured from hot-dip galvanized steel, this lath offers exceptional corrosion resistance, even in coastal or humid environments. The dimpled design also improves airflow behind the plaster, promoting uniform drying and minimizing the risk of blistering or delamination.
It is widely used in stucco walls, ceilings, fireproofing systems, and EIFS (Exterior Insulation and Finish Systems) — ideal for both new construction and renovation projects requiring enhanced adhesion and long-term durability.
Features & Benefits
-
Enhanced Bonding: Dimpled surface increases keying and adhesion between plaster and base.
-
Corrosion Resistant: Hot-dip galvanized coating ensures long service life in demanding environments.
-
Crack Prevention: Provides even reinforcement, reducing shrinkage cracks in thick plaster layers.
-
Efficient Drainage & Ventilation: Dimples create micro-channels that allow moisture evaporation.
-
Easy Installation: Lightweight, flexible, and easy to fasten with nails, screws, or wire ties.

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.
