As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory (established in 1998), we are proud to present our G90 Galvanized Ribbed Expanded Metal Lath with a precise 0.6mm thickness and 1 inch mesh. Designed specifically for plastering applications, this lath provides superior bonding for cement, stucco, and plaster, ensuring long-lasting structural integrity. With over 20 years of export experience and an annual export value exceeding US$5 million, our products are trusted by contractors across North America, South America, Europe, and beyond.
Our expanded metal lath is manufactured from high-quality G90 galvanized steel coils, offering excellent corrosion resistance and durability. The ribbed surface enhances mechanical keying with plaster, preventing delamination and cracking. The 0.6mm thickness strikes a perfect balance between strength and flexibility, making it easy to cut and install on walls, ceilings, and curved surfaces. The 1 inch (25.4mm) diamond mesh opening allows for efficient plaster penetration while maintaining a robust substrate.
Below is a detailed specification table for your reference:
| Parameter | Value |
|---|---|
| Material | G90 Hot-Dip Galvanized Steel |
| Thickness | 0.6mm (0.024 inch) – 23 Gauge |
| Mesh Opening | 1 inch (25.4mm) diamond shape |
| Rib Height | Approx. 3.2mm (1/8 inch) |
| Sheet Width | 24 inches, 36 inches, 48 inches (customizable) |
| Sheet Length | 8 feet, 10 feet (custom lengths available) |
| Application | Plastering, stucco, ceiling reinforcement, exterior wall cladding |
Key Features & Benefits:
- Exceptional Bonding: The ribbed design and expanded pattern create a mechanical lock with plaster, reducing the risk of separation and cracking.
- Corrosion Resistance: G90 galvanization (equivalent to 0.90 oz/ft² zinc coating) provides long-term protection against rust and moisture, ideal for outdoor and high-humidity areas.
- Lightweight Yet Strong: At 0.6mm thickness, the lath is easy to handle and cut with standard tools, yet robust enough to support multiple layers of plaster without sagging.
- Versatile Mesh Size: The 1-inch opening allows proper plaster penetration while providing a dense substrate for uniform coverage.
- Cost-Effective: Compared to welded wire lath, expanded metal lath offers better material utilization and lower cost per square foot without compromising performance.
- Easy Installation: Can be stapled, nailed, or screwed to wood or metal studs. The flexible nature allows it to conform to curved surfaces and irregular shapes.
- Compliance: Manufactured to meet industry standards such as ASTM C847 for expanded metal lath, ensuring consistent quality.
Technical Advantages Explained:
The expanded metal process creates a continuous sheet without welded joints, eliminating weak points. The diamond-shaped openings are oriented to maximize tensile strength in both directions. The ribbed surface (raised strands) increases the surface area for plaster adhesion, resulting in a stronger composite wall system. Our G90 coating undergoes a hot-dip galvanizing process, providing a uniform zinc layer that lasts for decades in normal conditions.
Typical Applications:
- Interior and exterior plastering on walls and ceilings
- Stucco backing for residential and commercial buildings
- Reinforcement for fireproofing and acoustic panels
- Repair and renovation of existing plaster surfaces
- Decorative architectural elements (arches, coves, columns)

Frequently Asked Questions (FAQs)
1. What is the difference between expanded metal lath and welded wire lath?
Expanded metal lath is made from a single sheet of metal that is slit and stretched, creating a continuous mesh with no welds. This provides greater flexibility and uniform strength. Welded wire lath has welded intersections which can be weak points. Expanded metal lath is preferred for plastering due to its superior bonding characteristics.
2. Can this lath be used for exterior stucco?
Yes, the G90 galvanized coating provides excellent corrosion resistance for exterior applications. It is commonly used as a base for stucco on exterior walls, providing a mechanical key for the cementitious coating.
3. How do I cut and install the lath?
The lath can be cut with tin snips or a grinder with a metal cutting disc. It is typically attached to studs or framing using galvanized staples, roofing nails, or self-tapping screws. Overlap sheets by at least 1 inch at joints for continuity.
4. What is the weight per square foot of this lath?
Approximately 0.8-1.0 lb per square foot depending on sheet size. The exact weight can be provided upon request for a specific size.
5. Do you offer custom sizes?
Yes, we can customize width (from 12 inches to 60 inches) and length (up to 12 feet) to suit your project. Minimum order quantities may apply for custom sizes.
6. Is this product compliant with ASTM standards?
Our expanded metal lath is manufactured in accordance with ASTM C847 standard for expanded metal lath. We can provide a certificate of compliance upon request.
7. What is the zinc coating weight for G90?
G90 indicates a zinc coating weight of 0.90 oz/ft² (approximately 275 g/m²) total both sides. This is a standard specification for corrosive environments.
8. Can I get a sample before placing a bulk order?
Absolutely. We offer free samples (shipping cost may apply) for evaluation. Contact our sales team with your requirements.
