When you choose our ribbed expanded metal lath, you are investing in a product that has been refined over decades of wire mesh manufacturing. The 0.5" x 0.5" opening is specifically designed to work with standard stucco scratch coats, providing ample area for mortar to key into the mesh. Compared to woven wire lath, expanded metal offers superior rigidity and resistance to sagging during application.
Frequently Asked Questions
Q1: What is the difference between ribbed and flat expanded metal lath?
A: Ribbed lath has raised ridges that increase stiffness and provide a better mechanical key for plaster. Flat lath is more flexible but may not bond as effectively. Our ribbed version is recommended for stucco applications where adhesion is critical.
Q2: Can this lath be used over wood or metal framing?
A: Yes, it is compatible with both wood and metal studs. For wood, use galvanized staples or roofing nails; for metal, use self-tapping screws. A weather-resistant barrier is typically required behind the lath.
Q3: Is the galvanized coating smooth or rough?
A: The coating is smooth and bright, with no sharp edges. It passes standard bend tests without flaking, ensuring safe handling and long-term durability.
Q4: Do you offer custom widths and lengths?
A: Absolutely. We can slit or cut sheets to your exact dimensions. Please contact our sales team with your specifications for a quote.
Q5: What is the weight of a standard sheet?
A: A 4 ft x 8 ft sheet weighs approximately 25–30 lbs, depending on the exact rib pattern and galvanizing thickness. This makes it manageable for one person to install.
Q6: How does the 0.5" opening compare to other sizes?
A: The 0.5" x 0.5" opening is the most common for stucco. It provides a balance between mortar keying and material strength. Larger openings (e.g., 3/4") are used for heavier plasters, while smaller openings (e.g., 1/4") are for thin-coat systems.
Q7: Can I get a sample before placing a bulk order?
A: Yes, we offer free samples (shipping cost applies) for you to evaluate the quality and compatibility with your plaster system. Contact us to arrange a sample.
Q8: Is this product suitable for external soffits or ceilings?
A: Yes, it can be used for horizontal applications. Ensure proper fastening every 6 inches and use a compatible lath clip or furring channel if needed.
