At Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer established in 1998, we bring over two decades of expertise to the production of 0.5mm Thick Galvanized Ribbed Expanded Metal Lath for Plastering with a precise 1/2 inch mesh. This product is engineered to deliver superior adhesion for plaster and stucco applications, combining strength, flexibility, and corrosion resistance. With an annual export value of US$5 million to US$10 million, we serve clients across North America, South America, Europe, Asia, and beyond, ensuring consistent quality and reliable supply.
Our expanded metal lath is manufactured from high-grade galvanized steel coils, expanded and flattened to create a rigid diamond-pattern mesh with raised ribs. The 0.5mm thickness provides an optimal balance between structural integrity and ease of handling, while the 1/2-inch mesh opening ensures excellent mechanical key for plaster. The ribbed surface further enhances the bond between the lath and the plaster, reducing the risk of cracking or delamination. Whether you are working on interior walls, exterior facades, or ceiling systems, this product is a reliable choice for professional contractors and builders.
Key Features & Benefits
- Heavy-Duty Galvanization: Hot-dip galvanized coating provides exceptional resistance to rust and corrosion, extending the lifespan of the lath even in humid or coastal environments.
- Ribbed Design for Superior Bonding: The raised ribs create a mechanical interlock with plaster, stucco, or mortar, ensuring a strong, durable surface.
- 0.5mm Thickness: Offers enough rigidity to hold shape during installation while remaining easy to cut and shape with standard tools.
- 1/2 Inch Mesh Opening: Optimized for plaster penetration and keying, compatible with common plastering techniques and materials.
- Versatile Application: Ideal for scratch coat, brown coat, and finish coat in stucco systems; also suitable for fireproofing, partition walls, and ceiling reinforcement.
- Easy Installation: Lightweight yet sturdy; can be quickly attached to wood or metal studs using staples, nails, or screws.
- Customizable Dimensions: Available in standard sizes (e.g., 27" x 96" sheets) and we offer custom cutting to meet project-specific requirements.

Our 0.5mm thick galvanized ribbed expanded metal lath has been widely used in residential and commercial construction projects across North America, South America, Eastern Europe, and Southeast Asia. Contractors appreciate its ease of use and the strong bond it creates with cement-based plasters. The 1/2-inch mesh size is particularly effective for stucco applications where a thick base coat is required.
Frequently Asked Questions (FAQ)
Q1: What is the difference between expanded metal lath and welded wire lath?
A: Expanded metal lath is made from a single sheet of metal that is slit and stretched, creating a diamond-shaped mesh with no welds or joints. This gives it superior strength and flexibility. Welded wire lath is made from separate wires welded together, which can be less rigid and prone to weld failure under stress.
Q2: Can this lath be used for exterior stucco?
A: Yes, this product is specifically designed for exterior stucco applications. The galvanized coating provides excellent weather resistance, and the ribbed surface ensures a strong mechanical bond with the stucco base coat.
Q3: Is the 0.5mm thickness suitable for ceiling applications?
A: Absolutely. The 0.5mm thickness provides enough rigidity to span between ceiling joists without sagging, while still being lightweight enough to handle overhead. For large areas, we recommend additional support furring channels.
Q4: Do you offer custom sizes or cut-to-length sheets?
A: Yes, we can customize sheet dimensions, including width, length, and even mesh opening size upon request. Please contact our sales team with your specific requirements.
Q5: How does the galvanized coating prevent rust?
A: The hot-dip galvanizing process coats the steel with a layer of zinc that acts as a sacrificial anode. Even if the surface is scratched, the zinc continues to protect the steel from corrosion. Our standard coating meets ASTM A653 specifications.
Q6: What is the recommended method for attaching this lath to wood studs?
A: For wood studs, use galvanized staples (1/2-inch crown, 1-inch leg) or roofing nails with a 3/8-inch head. Space fasteners every 6 inches along the edges and every 12 inches in the field.
Q7: Can this lath be used with cement board or fiber cement panels?
A: While primarily designed for direct plaster application, it can also be used as a reinforcement layer behind cement board or as a base for thin-coat systems. Always consult the manufacturer of your plaster system for compatibility.
Q8: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 500 sheets for common sizes. For smaller quantities, please inquire, as we may be able to accommodate sample orders or partial pallets.
