As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we take pride in offering our 1 Year Warranty Galvanized Ribbed Expanded Metal Lath for Plastering with Mill Test Report. This product is engineered to provide a strong, durable base for plaster, stucco, and cement applications, ensuring excellent adhesion and long-term structural integrity. With over two decades of experience in wire mesh manufacturing and an annual export value of US$5–10 million, our lath is trusted by contractors worldwide for its consistent quality and reliable performance.
Our expanded metal lath is manufactured from high-grade galvanized steel coils, expanded and flattened into a uniform ribbed pattern. The ribs create mechanical keying for plaster, significantly reducing the risk of cracking or delamination. The hot-dip galvanized coating provides superior corrosion resistance, making it suitable for both interior and exterior applications. Each batch is accompanied by a mill test report to verify material composition and mechanical properties, giving you full traceability and peace of mind.
Key Features & Technical Specifications
- Ribbed Design: Raised ribs (approx. 3/16″ – 1/4″) enhance plaster bonding, reducing waste and labor time.
- Galvanized Coating: Hot-dip galvanized per ASTM A653 – meets or exceeds industry standards for rust prevention.
- Open Mesh Structure: Lightweight yet strong, allowing plaster to penetrate and lock mechanically.
- Mill Test Report: Provided with each shipment to certify tensile strength, yield point, and coating weight.
- 1-Year Warranty: Covers manufacturing defects – demonstrating our confidence in product durability.
- Customizable Sizes: Available in standard 4x8 ft sheets or cut-to-length per your project requirements.
- Easy Installation: Can be cut with tin snips and fastened with staples or screws – no special tools needed.
