Anping Xinye Metal Wire Mesh Products Co., Ltd is proud to present our Expanded Metal Lath – a high-quality, precision-engineered construction material designed for professional plastering, stucco, and concrete reinforcement applications. Manufactured in our facility in Hengshui, Hebei, China, this 18-gauge plain steel expanded metal lath features a 3/4 x 1/2 inch diamond pattern and is available in convenient 2x4 ft panels. Our lath provides excellent bonding surface for cementitious materials, ensuring structural integrity and long-lasting performance in walls, ceilings, and other architectural elements.
Each panel is produced using advanced expansion machinery that uniformly stretches and slits steel sheets, creating a consistent diamond mesh without waste. The result is a durable, lightweight yet strong lath that offers superior tensile strength and excellent adhesion for plaster and stucco. Whether you are a contractor working on a large commercial project or a DIY enthusiast, our expanded metal lath delivers reliable performance and ease of installation.
Key Features & Benefits
- Uniform Diamond Pattern: 3/4 x 1/2 inch diamond openings provide optimal keying for plaster and stucco, reducing material waste and ensuring even coverage.
- 18 Gauge Thickness: Offers a balance of rigidity and flexibility – strong enough to support heavy coats of plaster yet easy to cut and shape on site.
- Plain Steel Construction: Made from high-quality low-carbon steel, suitable for interior applications where corrosion resistance is not a primary concern. For exterior use, galvanized or coated options are available upon request.
- Standard 2x4 ft Panel Size: Convenient for handling and transportation, minimizing joints and speeding up installation. Custom sizes can be supplied for bulk orders.
- Lightweight yet Strong: Expanded metal lath is significantly lighter than welded wire mesh while offering comparable strength, reducing structural load.
- Excellent Adhesion: The raised, sharp edges of the expanded metal create a mechanical bond with plaster, preventing delamination and cracking.
- Versatile Application: Ideal for interior plaster walls, ceilings, soffits, exterior stucco, and as a reinforcement base for concrete overlays and fireproofing.

Our expanded metal lath is manufactured in strict accordance with industry standards. Each panel is inspected for dimensional accuracy, mesh consistency, and surface quality before packaging. The 18-gauge thickness provides sufficient rigidity to maintain its shape during installation, while the 3/4 x 1/2 inch diamond pattern ensures excellent plaster penetration and mechanical interlock. For projects requiring enhanced corrosion resistance, we offer hot-dip galvanized or epoxy-coated variants – please contact our sales team for custom requirements.

Frequently Asked Questions
-
What is the difference between expanded metal lath and welded wire lath?
Expanded metal lath is made by slitting and stretching a solid sheet of steel, creating a continuous diamond mesh with no weak points. Welded wire lath is made from separate wires welded together. Expanded metal lath generally offers better adhesion for plaster and higher tensile strength in all directions. -
Can this lath be used for exterior stucco applications?
Our plain steel lath is suitable for interior applications. For exterior use where moisture exposure is expected, we recommend ordering galvanized or stainless steel expanded metal lath to prevent rust. Please inquire about coated options. -
What tools are needed to cut the panels?
Standard tin snips or aviation snips work well for cutting expanded metal lath. For larger cuts, a reciprocating saw with a metal-cutting blade can be used. Always wear appropriate safety gloves and eye protection when cutting. -
How much weight can one panel support?
Expanded metal lath is primarily designed as a reinforcement base for plaster, not as a load-bearing structure. It provides excellent tensile reinforcement for the cementitious material. The weight capacity depends on the installation method, fastening, and substrate. -
Do you offer custom sizes or different gauges?
Yes, we can manufacture expanded metal lath in various panel sizes, gauges (from 16 to 20 gauge), and diamond dimensions. Minimum order quantities may apply for custom specifications. Contact us with your requirements. -
Is this product compliant with building codes?
Our expanded metal lath is manufactured to meet general industry standards for metal lath used in plastering and stucco. We recommend checking local building codes for specific requirements regarding material thickness and mesh size. We can provide material test reports upon request. -
How should I store the panels before installation?
Keep the panels in a dry, covered area to prevent moisture exposure. If stored outdoors, cover with a waterproof tarp and ensure good ventilation to avoid condensation. Plain steel lath may develop surface rust if exposed to high humidity for extended periods – this is cosmetic and does not affect performance in interior applications. -
Do you provide samples before bulk order?
Yes, we can provide small sample panels for evaluation. Please contact our sales team with your shipping details. A nominal fee may apply for samples, which is refundable upon placing a confirmed order.
Note: All product specifications are subject to standard manufacturing tolerances. For critical applications, please request a material certificate. Plain steel lath is not recommended for direct exposure to corrosive environments without additional protective coating.
