What Is Stainless Expanded Metal Lath?

Stainless expanded metal lath is a rigid, self-furring metal reinforcement sheet made from 304 or 316 stainless steel, precision-expanded to create a uniform diamond pattern. It is engineered to provide a stable mechanical bond for stucco, plaster, cement mortar, and exterior insulation finishing systems (EIFS).

The unique ribbed and dimpled design of expanded metal lath creates a strong anchor for plaster and concrete, preventing cracking, shrinking, and delamination over time. Stainless steel grade ensures zero rust, corrosion, or degradation – even in harsh outdoor, coastal, or chemical environments.

Our stainless expanded metal lath conforms to international ASTM C847 and EN standards, making it suitable for structural and non-structural wall reinforcement, ceiling plastering, chimney repair, pool surrounds, and exterior facade systems. It is lightweight, flexible, and easy to cut and install on vertical and curved surfaces.

Key Advantages of Stainless Expanded Metal Lath

Stainless steel expanded metal lath outperforms traditional galvanized metal lath, fiberglass mesh, and plastic lath in nearly every construction application. Its corrosion resistance and structural strength make it the premium choice for high-quality, long-lasting building projects.

• Superior Corrosion Resistance: 304/316 stainless steel never rusts, even in coastal or high-moisture areas
• Exceptional Bond Strength: Diamond pattern locks tightly with plaster, stucco, and concrete
• Long Service Life: Lasts 30+ years, 5x longer than galvanized lath
• Self-Furring Design: Creates a 1/4” air gap for proper mortar adhesion and ventilation
• High Structural Strength: Prevents wall cracking, warping, and surface deterioration
• Weather & Chemical Resistant: Withstands UV rays, saltwater, acids, and industrial contaminants
• Flexible & Formable: Bends easily for curved walls, columns, arches, and rounded surfaces
• Eco-Friendly & Recyclable: 100% recyclable stainless steel with green manufacturing

These benefits make our stainless expanded metal lath the top choice for luxury construction, coastal buildings, commercial facades, and infrastructure projects. For precision applications, our small hole expanded metal mesh provides enhanced reinforcement for thin plaster layers.

Stainless Steel Grades for Expanded Metal Lath

We produce stainless expanded metal lath in two professional-grade alloys: 304 and 316 stainless steel. Each grade is selected based on environmental exposure, moisture levels, and corrosion resistance requirements for the construction project.

304 stainless steel lath is the standard choice for most interior and exterior construction projects in dry climates. 316 marine-grade stainless lath is mandatory for coastal regions, saltwater pools, and industrial facilities exposed to corrosive elements. Both grades are 100% recyclable and meet international building codes.

Standard Specifications of Stainless Expanded Metal Lath

Our stainless expanded metal lath is manufactured to strict industry dimensions for universal compatibility with stucco, plaster, and concrete systems. We offer both standard and custom specifications to meet project-specific requirements.

Common Dimensions

Standard sheet size: 27” × 96” (2.25ft × 8ft) – the industry norm for construction. We also supply custom-cut sheets and rolls for large-scale projects. Thickness ranges from 0.4mm to 1.2mm, with 0.5mm and 0.6mm being the most popular for stucco application.

Diamond Opening Sizes

Standard diamond openings: 16mm × 8mm and 20mm × 10mm – optimized for maximum mortar grip and workability. The self-furring ribs are formed to 1/4” height, ensuring proper mortar penetration and ventilation behind the lath.

As a professional expanded metal mesh facade supplier, we engineer our lath to balance flexibility and rigidity, making it easy to install while maintaining structural stability for heavy plaster and stucco loads.

Primary Applications of Stainless Expanded Metal Lath

Stainless expanded metal lath is a versatile construction material used across residential, commercial, and industrial building projects. Its corrosion resistance and bonding strength make it indispensable for high-quality exterior and interior work.

• Stucco & Plaster Wall Reinforcement: Prevents cracking and ensures long-term surface integrity
• Exterior Facade Systems: Ideal for modern building facades and EIFS insulation systems
• Concrete & Masonry Reinforcement: Strengthens thin concrete overlays and repair works
• Pool & Spa Surrounds: 316 stainless lath resists pool chemicals and moisture
• Chimney & Fireplace Repair: Heat-resistant stainless steel withstands high temperatures
• Curved Wall & Column Plastering: Flexible design conforms to rounded surfaces
• Roof & Underlayment Reinforcement: Adds structural support to roofing systems
• Restoration & Historic Preservation: Durable, non-corrosive support for old buildings

Our lath is approved for use in commercial construction, government projects, and luxury residential builds. It is the preferred reinforcement material for architects and contractors seeking long-term performance and low maintenance costs.

Installation Best Practices for Stainless Expanded Metal Lath

Proper installation ensures maximum performance and longevity of stainless expanded metal lath. The process is straightforward for professional contractors and follows standard stucco and plastering protocols.

Start by attaching the lath to wood or metal studs using corrosion-resistant screws or nails, spaced 6 inches apart on center. Overlap sheets by 1 inch vertically and horizontally to create a continuous reinforcement surface. The self-furring ribs must face outward to allow proper mortar flow behind the lath.

For curved surfaces, gently bend the lath to match the radius – stainless steel’s flexibility allows smooth forming without breaking. Apply scratch coat, brown coat, and finish coat mortar in layers, allowing proper curing time between coats. Our custom expanded metal fabrication team can provide pre-formed lath for complex curved projects.
