ASTM A740 Galvanized Square Wire Mesh Panels, Sheets, and Rolls

 

Galvanized Square Wire Mesh is a versatile and durable material characterized by its square grid pattern, typically crafted from high-quality steel wire and coated with a layer of zinc for enhanced corrosion resistance. This mesh is known for its strength, stability, and longevity, making it an ideal choice for a wide range of applications. It is commonly used in industrial settings for fencing, machine guarding, and storage solutions, as well as in residential projects for window screens, garden fencing, and pet enclosures. The galvanized coating ensures it can withstand harsh environmental conditions, providing long-lasting protection and reducing maintenance needs. With its robust construction and reliable performance, Galvanized Square Wire Mesh is a preferred solution for both practical and aesthetic purposes across various sectors.

Wire Diameter

• Gauge 18#: The 18# wire gauge corresponds to a diameter of 0.0475 inches (1.2 mm). This thicker wire is used for heavy-duty applications where additional strength is required.
• Gauge 28#: The 28# wire gauge corresponds to a diameter of 0.0143 inches (0.36 mm). This thinner wire is suitable for applications requiring finer mesh and less structural load.

Mesh Count

• Low Mesh Count: Low mesh counts, such as 3 mesh, have larger openings measuring approximately 0.333 inches (8.46 mm) between wires. These are ideal for applications that require less precision and more airflow.
• High Mesh Count: High mesh counts, such as 60 mesh, feature smaller openings of about 0.0117 inches (0.3 mm). These are used for fine screening and filtering applications.

Standard Shapes

• Sheets: Galvanized square wire mesh sheets are typically available in standard widths of 3 feet (914 mm) and 4 feet (1219 mm). These are used in construction and other structural applications.
• Rolls: Rolls of galvanized square wire mesh provide flexibility and ease of transport. Standard roll widths are also 3 feet (914 mm) and 4 feet (1219 mm), with variable lengths to suit different project needs.

Finishing

• Galvanized Before Weaving (GBW): GBW involves coating the wire with zinc before it is woven into mesh. This process results in a smoother finish and enhances rust resistance.
• Galvanized After Weaving (GAW): GAW involves weaving the wire first and then galvanizing the entire mesh. This ensures thorough coverage of the zinc coating, providing robust corrosion protection.

Weave Types

The plain weave is the most common type, where the wire alternates over and under adjacent wires. This simple yet effective technique creates a uniform and stable grid.

Construction Type

• High-Quality Steel Wire: The mesh is constructed from high-quality steel wire that ensures strength and durability. The zinc coating prevents rust and corrosion.
• Galvanizing Process: The mesh can be galvanized either before or after weaving, depending on the desired finish and application. This enhances the longevity and resilience of the mesh.

Sizes

• Widths: Standard widths for galvanized square wire mesh are 3 feet (914 mm) and 4 feet (1219 mm). These sizes are versatile for various installation needs.
• Lengths: Common roll lengths range from 25 feet (7.62 meters) to 100 feet (30.48 meters). This variety accommodates both small-scale and large-scale uses.

Typical Standards

• ASTM A740: Galvanized square wire mesh typically adheres to ASTM A740 standards, ensuring quality and consistency in manufacturing and performance.

Packaging

• Bundles: The mesh is often rolled and packaged in bundles for convenient handling and transportation.
• Protective Wrapping: Protective wrapping, such as plastic film or waterproof paper, is used to shield the mesh from environmental factors during shipping and storage.
