At Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we specialize in manufacturing high-quality metal mesh products for global construction markets. Our Galvanized Ribbed Expanded Metal Lath is specifically designed for interior ceiling plastering and rendering, offering superior adhesion and structural integrity. With over 20 years of experience and annual exports exceeding US$5 million, we are a trusted partner for contractors, builders, and distributors worldwide.
This product features a unique ribbed pattern that enhances rigidity while maintaining flexibility for easy cutting and installation. The expanded diamond mesh provides excellent keying for plaster, cement, or stucco, ensuring a long-lasting bond. Our galvanized coating protects against rust and corrosion, making it suitable for humid indoor environments such as bathrooms, kitchens, and basements.
Key Features and Benefits
- Galvanized Surface: Hot-dipped galvanizing provides excellent corrosion resistance, extending the service life of the lath in moist interior conditions.
- Ribbed Structure: Longitudinal ribs increase tensile strength and prevent sagging during plaster application, ensuring a flat and even ceiling surface.
- Expanded Diamond Mesh: The open design creates mechanical keys for plaster, reducing the risk of delamination or cracking.
- Easy to Cut and Shape: Can be cut with standard tin snips or power shears, allowing quick adaptation to irregular ceiling areas.
- Lightweight yet Strong: Low weight per sheet reduces handling fatigue and lowers shipping costs, while maintaining structural support.
- Versatile Application: Suitable for both manual and machine-applied plaster, as well as cement renders and stucco finishes.
- Customizable Dimensions: Available in various sheet sizes, thicknesses, and rib heights to meet specific project requirements.

Why Choose Our Galvanized Ribbed Expanded Metal Lath?
Our lath is manufactured using advanced stamping and expanding technology, ensuring consistent mesh dimensions and rib profiles. The hot-dip galvanization process applies a uniform zinc coating that bonds metallurgically to the steel, providing superior protection compared to electro-galvanizing. This results in a product that can withstand the alkaline environment of cement plaster without premature corrosion.
The ribbed design not only adds structural strength but also acts as a spacer, maintaining a consistent gap between the lath and the substrate. This allows plaster to fully encapsulate the lath, creating a monolithic bond. Contractors report reduced labor time and material waste when using our lath due to its ease of alignment and fastening.
Frequently Asked Questions
-
Q: What is the difference between ribbed and flat expanded metal lath?
A: Ribbed lath has raised longitudinal ribs that increase stiffness and prevent sagging, making it ideal for ceiling applications. Flat lath is more flexible and often used for curved surfaces or wall patching. -
Q: Can this product be used for exterior plastering?
A: While it is primarily designed for interior ceilings, it can be used for exterior soffits or protected areas. For direct exposure to weather, we recommend consulting our technical team for a suitable heavy-duty option. -
Q: What is the recommended mesh size for plaster adhesion?
A: Our standard diamond mesh (approx. 10mm x 25mm) provides excellent keying for most plaster mixes. For finer plasters, we can supply smaller mesh openings upon request. -
Q: How should I cut the lath on site?
A: The lath can be cut with tin snips, aviation shears, or a grinder with a metal cutting disc. Always wear protective gloves and eyewear to avoid sharp edges. -
Q: Do you offer custom sizes?
A: Yes, we can produce sheets in non-standard widths, lengths, and thicknesses. Please provide your desired dimensions and quantity for a quotation. -
Q: Is the galvanized coating safe for indoor use?
A: Absolutely. The zinc coating is non-toxic and does not emit harmful fumes. It is commonly used in residential and commercial indoor applications. -
Q: What is the typical lead time for bulk orders?
A: For standard specifications, lead time is 15–20 days after deposit. For customized orders, please allow 20–30 days based on production schedule. -
Q: Can I get samples before placing a large order?
A: Yes, we offer free samples (customer pays shipping) for quality evaluation. Contact our sales team to arrange sample delivery.
