Expanded Metal Lath | Premium Self-Furred & Rib Lath for Stucco & Plaster
ANPING METAL MESH – Leading Manufacturer of Expanded Metal Lath
Since 2005, we have been a professional China expanded metal mesh manufacturer specializing in high-quality expanded metal lath – the essential reinforcement material for stucco, plaster, concrete, and masonry applications. Our product range includes self-furred lath, rib lath, flat lath, and galvanized expanded metal lath sheets/rolls, fully compliant with ASTM A82, ASTM C1063, and EN building standards. As a trusted expanded metal mesh facade supplier, we also provide decorative lath systems for exterior wall cladding and architectural plaster systems.
What is Expanded Metal Lath?
Expanded metal lath is a lightweight, rigid metal mesh made by slitting and expanding galvanized steel or stainless steel sheets into a uniform diamond pattern. It is designed to reinforce plaster, stucco, and concrete by creating a strong mechanical bond between the base wall and the finish material.
Unlike wire mesh lath, expanded metal lath is a single-piece construction with no welds or breaks, delivering superior strength, crack resistance, and durability. It is the industry standard for commercial and residential exterior stucco systems, interior plaster walls, and fire-rated assemblies.
Our Anping expanded metal factory produces lath with precise diamond openings, uniform thickness, and consistent furrowing for maximum plaster grip.
Types of Expanded Metal Lath We Supply
| Lath Type | Key Features | Best For |
|---|---|---|
| Self-Furred Expanded Metal Lath | Dimpled surface for 1/4" plaster clearance | Standard stucco & plaster walls |
| Rib Lath (Heavy-Duty) | Reinforcing ribs for high-strength applications | Ceilings, long spans, concrete |
| Flat Expanded Lath | Smooth, low-profile surface | Thin plaster & interior use |
| Strip Lath | Narrow strips for corners & repairs | Corner beads, patch work |
| Corner Lath | Pre-formed 90° angle | Wall corners & door frames |
All our expanded metal lath products use hot-dip galvanized steel for maximum rust resistance, making them suitable for exterior stucco systems and wet environments. We also offer stainless steel lath for coastal and corrosive environments.

Core Benefits of Expanded Metal Lath
Expanded metal lath outperforms traditional wire lath and fiber mesh in nearly every category:
Unmatched Strength
One-piece expanded construction – no welds to break – creates superior structural reinforcement.
Superior Plaster Bond
Diamond openings and furred surface lock plaster/stucco in place, preventing cracking, delamination, and falling finish.
Corrosion Resistance
Hot-dip galvanized coating protects against rust for exterior and wet-area applications.
Easy Installation
Lightweight, flexible, and easy to cut, fasten, and form around corners and curves.
Fire & Mold Resistant
Non-combustible metal construction improves fire ratings and resists mold growth.
Top Applications of Expanded Metal Lath
Expanded metal lath is the foundation of high-quality plaster and stucco systems worldwide:
Exterior Stucco Walls: Primary reinforcement for residential and commercial exterior stucco systems (most common use).
Interior Plaster Walls & Ceilings: Creates smooth, crack-resistant interior plaster finishes.
Concrete Reinforcement: Rib lath reinforces thin concrete slabs, stairs, and architectural concrete.
Masonry & Brick Repair: Repairs damaged brick, stone, and concrete surfaces.
Fire-Rated Assemblies: Used in fire-resistant wall and ceiling systems.
Architectural Facade Cladding: Decorative expanded lath for modern exterior wall designs.
Installation Advantages of Our Expanded Metal Lath
Our expanded metal lath is designed for fast, efficient installation by contractors:
