Features

• High strength and stability: Made from carbon steel, stainless steel, or hot-dip galvanized steel, the diamond-shaped mesh distributes stress evenly, enhancing load-bearing capacity, improving structural stability, and reducing concrete deformation and cracking.
• Strong Adhesion: The diamond-shaped perforated design provides mechanical interlocking points, enhancing adhesion with plaster, tiles, and other materials, preventing peeling, and adapting to uneven walls.

Expanded Metal Mesh

• High-Temperature Resistance and Fireproofing: High-temperature resistant, suitable for chimney wrapping or fireproofing of steel structures, enhancing insulation and fireproofing performance.
• Impact-Resistant and Breathable: As an exterior wall protective layer, it withstands impacts while remaining breathable, preventing mold growth and peeling.
• Corrosion-resistant: Made of hot-dip galvanized or stainless steel, it is corrosion-resistant, suitable for harsh environments, and extends service life.
• Easy to process and install: Soft in texture, it is easy to cut and bend, adapts to various structures, and enables efficient installation.
• Decorative: The diamond-shaped texture is aesthetically pleasing, combines well with various materials, and enhances spatial depth.
• Cost-effective: High cost-effectiveness, reduces post-installation maintenance, recyclable, and aligns with sustainable development.

What is diamond mesh lath used for?

Building reinforcement and support

• As a wall plaster layer, it enhances adhesion and prevents cracking; it assists in tile paving and improves the fixing effect.
• As a supporting skeleton such as gypsum board in suspended ceilings and ceilings to ensure structural stability.
• Used for reinforcement of prefabricated components or on-site cast concrete, as internal support for concrete pouring.

Wall decoration and installation assistance

• Combined with wall panels or gypsum boards, it forms a diamond texture wall decoration effect and increases the sense of space hierarchy.
• In the background wall design, diamond patterns are spliced with wood, stone and other materials to create a unique visual style.
• As the base material of the wall panel, it provides a flat installation surface after being fixed to the wall, which is suitable for TV walls and sofa walls in living rooms and bedrooms.

Protection and special environment applications

• Used for flue and pipe wrapping, it can enhance the fixation of the insulation layer; as a protective layer for the exterior wall insulation system.
• In agriculture and breeding, it is used as a pen fence and protective net to prevent animal biting and provide good ventilation.

Industry and machinery

• In machinery manufacturing, it is used for filtering, screening or protective devices, such as equipment housings and safety fences; it can also be used as a component of heat dissipation or ventilation structures.

Diamond Mesh Lath Shape Classification

The following is a summary of the classification and characteristics of diamond mesh panels (also known as diamond-shaped mesh panels/stretched mesh) based on their structural features:

1. Standard diamond mesh

Symmetrical hexagonal holes with a fixed ratio between the long diagonal (pitch) and the short diagonal (rib width). Used for building fences, platform steps, and mechanical protection.

2. Flat-strip diamond mesh

The mesh strips are wider than they are thick, forming flat, ribbon-like strips with elongated openings. Advantages include reduced weight and enhanced longitudinal load-bearing capacity, making it suitable for conveyor belts and filters.

3. Round Bar Diamond Mesh

The cross-section of the mesh bars is circular or semi-circular, with smooth edges. Used in areas with frequent human contact, such as stair anti-slip plates and decorative facades.

4. Special-Shaped Diamond Mesh

Wavy ribs, mesh strips formed by pressing waves, enhancing rigidity (industrial platforms). Serrated edges with spikes, used for anti-theft fences.

5. Combination diamond mesh

Diamond holes mixed with other geometric shapes (such as squares, hexagons). Used for decorative curtain walls, art installations, and other special visual effect requirements.

FAQs

What is lath mesh?

Expanded metal lath is formed from sheet steel that has been slit and expanded to form hundreds of “keys” per square yard. It is proven over time to possess exceptional strength and flexibility, making it the preferred metal base requested by contractors and design professionals.

What is diamond mesh?

Diamond mesh is woven on a special weaving machine. This machine weaves the mesh in a diamond orientation, rather than the standard square orientation. In addition to being able to produce this diamond orientation, these machines can also weave metal steel mesh in extremely wide widths.

What is the difference between 2.5 and 3.4 Diamond mesh lath？

Stucco diamond mesh comes in 2 regular weights: 2.5 and 3.4, meaning the stucco weighs 2.5 pounds per square yard or 3.4 pounds per square yard. The 2.5 is good for side walls, and 3.4 is required for ceilings and roofs to prevent sagging. In government work, 3.4 is required for both walls and ceilings.

Stainless steel diamond mesh lath

When less corrosion resistance is required, G90 coated or standard G60 galvanized steel metal lath can be used. Where the highest level of corrosion resistance is required, a stainless steel substrate must be used for both interior and exterior installations.

SS304 and SS316 Mesh Lath

• SS304: Available as a product providing an excellent corrosive resistant material for specialty lath applications. The product can be used over insulation boards to carry conventional stucco finishes and for external insulation requirements.
• SS316: Can be used in swimming pool applications to resist the chemical cleaning agents in swimming pools. Also used for lathing in coastal locations where atmospheric salt is a concern.

Galvanized diamond mesh lath

Galvanized diamond mesh slats refer to galvanized steel slats. Due to the galvanizing process on the surface, the slats have excellent corrosion resistance. The most commonly used sizes are:

• 4 galvanized diamond mesh lath.
• 27″ x 97″, G60 Galvanized Steel, Diamond,(approx. 68.58 cm x 246.38 cm).
• 4 Galvanized Diamond Lath 24″ x 96″.
• 27” X 96” 3.4# GALVANIZED self furred METAL LATH.

What is 3.4 galvanized diamond mesh lath?

3.4 means it weighs about 3.4 pounds, about 1.54 kilograms per square yard. The corresponding mesh strip size is 24 inches x 96 inches. 3.4 pounds per square yard is the necessary weight in-ceiling applications.

Diamond Mesh Lath Installation Tips

In construction applications, to avoid cracks in the wall later, the diamond metal lath should be overlapped by at least 1 inch. The diamond-shaped mesh with pits allows the lath to be moved away from the wall, allowing good penetration of the mortar and making the project stronger.
