Expanded Metal Rib Lath: High-Strength Stucco & Plaster Mesh
ANPING METAL MESH – Professional Metal Mesh Manufacturing Since 2005
Expanded metal rib lath is a heavy-duty, rib-reinforced expanded metal lath designed for stucco, plaster, concrete, and exterior insulation finishing systems (EIFS). Its unique ribbed structure provides superior strength, bonding, and crack resistance compared to standard lath.
As a professional manufacturer based in Anping County – the global Wire Mesh Capital – we produce galvanized and stainless steel expanded metal rib lath that meets ASTM international standards. Our products are widely used in building facade systems, wall plastering, and structural reinforcement projects worldwide.
What Is Expanded Metal Rib Lath?
Expanded metal rib lath is a self-furring, rib-stiffened expanded metal lath used as a base reinforcement for cement plaster, stucco, exterior wall cladding, and concrete rehabilitation. The raised ribs create a rigid framework that prevents bending, improves mortar adhesion, and eliminates surface cracking.
Types of Expanded Metal Rib Lath
We provide two professional-grade rib lath products for residential and commercial construction:
1. Hot-Dip Galvanized Expanded Metal Rib Lath
The industry standard for exterior stucco and plaster. Zinc coating protects against rust, weather, and moisture. Used for walls, ceilings, soffits, and EIFS systems.
2. Stainless Steel Rib Lath (304/316)
Premium corrosion-resistant lath for coastal, marine, and chemical-exposed environments. Used in hospitals, food plants, coastal buildings, and luxury construction.
3. Self-Furring Rib Lath
Designed with built-in dimples to maintain a uniform gap between lath and wall, ensuring full mortar encapsulation and strong bonding.
Standard Specifications
| Material | Sheet Size | Metal Thickness | Rib Height | Surface |
|---|---|---|---|---|
| Galvanized Steel | 27"×96" | 0.4mm–0.6mm | 3/8" (10mm) | Hot-Dip Galvanized |
| Galvanized Steel | 36"×96" | 0.45mm–0.7mm | 3/8" (10mm) | ASTM Standard |
| Stainless Steel 304 | 27"×96" | 0.5mm–0.7mm | 3/8" | Brushed |
All expanded metal rib lath products comply with ASTM C847, the international standard for metal lath used in plaster and stucco systems.
Key Advantages of Expanded Metal Rib Lath
- Superior Structural Strength: Ribbed design prevents bending and warping under load
- Excellent Mortar Bonding: Open diamond pattern locks in plaster/stucco securely
- Crack Resistance: Reinforces walls to eliminate shrinkage and surface cracks
- Self-Furring Design: Ensures full mortar coverage and strong adhesion
- Corrosion Resistant: Galvanized/stainless steel for long exterior life
- Easy Installation: Lightweight and flexible for walls, ceilings, and curves
- Cost Effective: Reduces plaster cracking and lowers maintenance costs
These benefits make expanded metal rib lath the preferred choice for professional plasterers and contractors worldwide.
Common Applications
Expanded metal rib lath is essential in modern construction and renovation:
- Exterior Stucco Walls: Primary reinforcement for residential and commercial stucco
- EIFS / Exterior Insulation Systems: Base mesh for insulated wall cladding
- Concrete Repair & Rehabilitation: Strengthens damaged concrete surfaces
- Ceiling & Soffit Plastering: Reinforces overhead plaster applications
- Fireproofing Systems: Base for fire-resistant cementitious coatings
- Foundation & Retaining Walls: Structural reinforcement for concrete
- Marine & Coastal Construction: Stainless steel lath for saltwater environments
Our rib lath is also used as a high-performance base for exterior wall cladding and facade reinforcement systems.
