Rust-resistant Expanded Metal Lath For Interior And Exterior Plastering

Rust-resistant Expanded Metal Lath For Interior And Exterior Plastering

High Strength – Excellent Keying – Ideal for Stucco and Plaster Applications

Expanded Metal Lath is manufactured from premium galvanized steel sheets that are slit and expanded to form a diamond mesh pattern. This design provides excellent plaster keying, superior strength, and uniform coverage for both interior and exterior wall systems.

Our expanded lath offers strong adhesion for stucco, plaster, cement, and fireproofing materials, ensuring crack resistance and a smooth surface finish. The open mesh structure allows the plaster to interlock, creating a strong mechanical bond with the substrate.
