What Is Expanded Metal Lath Selco?

Expanded metal lath Selco refers to a premium grade of expanded metal lath engineered for maximum stucco adhesion, structural reinforcement, and long-term durability in exterior and interior plaster systems. Selco-grade lath is widely recognized in the construction industry for its consistent quality, self-furring design, and compatibility with cement-based finishes.

Unlike standard metal lath, Selco-grade expanded metal lath features precision-formed ribs and dimples that create a uniform 1/4-inch space between the lath and the substrate. This self-furring design allows plaster and stucco to fully encapsulate the lath, creating a monolithic, crack-resistant surface that withstands weathering, settling, and structural movement.

Our expanded metal lath is manufactured using hot-dip galvanized steel, providing exceptional rust and corrosion resistance for outdoor applications. The diamond-shaped openings promote mechanical locking of stucco mixes, ensuring a strong, permanent bond that prevents delamination and surface failure over time.

As a leading expanded metal lath manufacturer, we produce Selco-equivalent lath in standard rolls and sheets to match industry dimensions, making it fully interchangeable with branded Selco products while offering factory-direct cost savings.

Key Specifications of Expanded Metal Lath Selco

Our expanded metal lath Selco meets all international construction standards and features precise specifications that ensure professional performance. Below are the standard technical details for our Selco-grade lath products:

These specifications ensure our expanded metal lath Selco provides optimal reinforcement for all types of stucco, plaster, and cementitious finishes. The uniform diamond pattern and self-furring ribs eliminate the need for separate furring strips, reducing installation time and material costs for contractors.

Every roll undergoes rigorous quality testing to ensure consistent thickness, opening size, and coating coverage. Our commitment to precision manufacturing makes our lath the preferred alternative to branded Selco products for professional plastering and construction projects.

Core Advantages of Expanded Metal Lath Selco

Expanded metal lath Selco offers distinct advantages over traditional wire lath, fiberglass mesh, and other reinforcement products, making it the industry standard for high-quality stucco and plaster installations.

The self-furring design is the primary benefit, creating a perfect gap between the lath and substrate that allows full plaster encapsulation. This eliminates hollow spots and ensures the stucco forms a solid, reinforced layer that resists cracking, chipping, and water penetration.

Superior bonding strength is another key advantage. The diamond-shaped openings and raised ribs create mechanical interlock with cement-based mixes, creating a permanent bond that cannot be achieved with flat mesh products. This bond strength ensures long-term structural integrity even in seismic zones and high-wind areas.

Hot-dip galvanized coating provides exceptional corrosion resistance, protecting the lath from rust and degradation in outdoor, humid, and coastal environments. This protective layer extends the service life of the entire stucco system, reducing maintenance and replacement costs.

Our galvanized expanded metal lath is also highly flexible and easy to install, conforming to curved surfaces, corners, and irregular substrates without breaking or tearing. This versatility makes it suitable for both flat walls and architectural details like arches, columns, and decorative moldings.

Primary Applications of Expanded Metal Lath Selco

Expanded metal lath Selco is a versatile construction material used in a wide range of residential, commercial, and industrial applications where durable stucco, plaster, or cement finishes are required.

**Exterior Stucco Walls** are the most common application. Selco-grade lath provides the necessary reinforcement for exterior stucco systems, protecting buildings from weather damage, moisture intrusion, and structural cracking. It is suitable for wood, steel, and masonry frame construction.

**Interior Plaster Systems** benefit from the lath's smooth reinforcement, creating flawless interior wall and ceiling surfaces. It reinforces gypsum plaster, lime plaster, and cement plaster applications in residential and commercial interiors.

**EIFS/Insulated Wall Systems** use expanded metal lath as a base layer for exterior insulation and finish systems, providing structural support for insulation boards and protective finish coats.

**Masonry & Concrete Repair** projects rely on Selco lath to reinforce damaged concrete and masonry surfaces, restoring structural integrity and providing a stable base for repair mortars.

**Architectural Details** like curved walls, domes, columns, and decorative trim require the flexibility of expanded metal lath to create smooth, reinforced surfaces that maintain their shape and structural strength over time.

Our lath is also widely used in commercial building construction, including schools, hospitals, offices, and retail spaces, where code-compliant, fire-resistant wall assemblies are required.

Installation Guide for Expanded Metal Lath Selco

Proper installation of expanded metal lath Selco is critical to achieving a durable, long-lasting stucco or plaster finish. Following industry best practices ensures optimal performance and compliance with building codes.

Begin by preparing the substrate, ensuring all surfaces are clean, dry, and structurally sound. Install building paper or weather-resistant barrier over wood or steel studs according to local building codes before applying the lath.

Install the lath with the raised ribs facing outward, away from the substrate. This maintains the critical 1/4-inch self-furring space required for full plaster encapsulation. Overlap horizontal seams by 1 inch and vertical seams by 2 inches to create continuous reinforcement.

Secure the lath using corrosion-resistant fasteners – galvanized nails or screws spaced 6 inches apart on centers and 4 inches apart on edges. For masonry substrates, use masonry nails or concrete screws to ensure firm attachment.

Fold lath at corners to create continuous reinforcement, avoiding gaps that can weaken the finished surface. For large surfaces, install additional control joints according to stucco system specifications to accommodate thermal movement.

Once installed, the lath should be taut and securely fastened with no loose areas. Properly installed expanded metal lath Selco provides an ideal base for scratch coat, brown coat, and finish coat applications, ensuring a professional, long-lasting result.
