Process Deep Dive:

Material Purity: We begin with premium raw materials, such as low-carbon Q195 steel for its excellent weldability and ductility, or Stainless Steel grades 304 and 316 for applications requiring supreme corrosion resistance, common in petrochemical and food processing industries.
Precision Welding: Our automated welding lines use computer-controlled electrical resistance welding. This process passes a high current through the intersecting wires, melting them at the junction point to form a homogenous bond. This is superior to manual welding as it guarantees uniform shear strength across the entire welded wire fabric, a critical factor for structural applications.
Advanced Surface Treatment: Post-welding, the mesh undergoes surface treatment. Hot-dip galvanizing (conforming to ASTM A123) provides a thick, robust zinc coating for long-term corrosion protection (often exceeding 20-30 years of service life). PVC coating adds an extra layer of chemical and UV resistance, ideal for harsh environments or aesthetic applications.
Rigorous Quality Assurance: Every batch is subjected to stringent testing. This includes dimensional accuracy checks, weld shear strength tests (as per ASTM A185/A497 for concrete reinforcement), and coating thickness analysis. This ensures that every product leaving our facility, from galvanized hardware cloth to heavy-duty welded fence panels, meets or exceeds international standards.

Decoding Technical Parameters: A Comprehensive Specification Guide

Understanding the technical specifications of welded wire mesh is crucial for selecting the right product. The interplay between wire gauge, mesh size, material, and finish determines the product's performance, lifespan, and suitability for a specific application. Below is a detailed table outlining common specifications.

Parameter	Common Range / Options	Technical Significance & Impact on Performance

Frequently Asked Questions (FAQ) about Welded Wire

1. What is the difference between Hot-Dip Galvanized (HDG) and Electro-Galvanized (EG) welded wire?

This is a crucial distinction affecting lifespan and cost. Hot-Dip Galvanizing involves immersing the fabricated mesh into a bath of molten zinc, creating a thick, durable, and metallurgically bonded alloy coating. It offers superior corrosion protection and is ideal for outdoor and harsh environments. Electro-Galvanizing uses an electrical current to deposit a much thinner layer of zinc. It provides a bright, smooth finish but offers only minimal corrosion resistance, making it suitable for indoor or dry applications where aesthetics are a priority.

2. How does wire gauge affect the strength of a welded wire panel?

Wire gauge is a primary determinant of strength and rigidity. The gauge system is inverse; a lower gauge number means a thicker and stronger wire. For example, an 8-gauge wire is significantly stronger and more rigid than a 16-gauge wire. The thickness directly impacts the panel's tensile strength (resistance to being pulled apart) and its ability to resist bending or impact. For security fencing or load-bearing applications, a heavier gauge (e.g., 8, 10, or 12) is essential.

3. What are the best materials for welded wire mesh in highly corrosive environments?

For the most demanding corrosive environments, such as marine, chemical processing, or wastewater treatment, Stainless Steel Type 316 (SS316) is the premium choice. It contains molybdenum, which significantly enhances its resistance to chlorides and acids. For a more cost-effective but still highly durable option, Hot-Dip Galvanized After Welding (GAW) mesh with a thick PVC coating provides a dual-barrier system against corrosive agents.

4. What are the standard installation guidelines for a welded fence?

Proper installation is key to performance. Key guidelines include: 1) Post Spacing: Posts should typically be spaced no more than 8-10 feet apart, closer for high-security applications. 2) Post Depth: At least one-third of the post length should be buried in the ground, set in concrete footings for maximum stability. 3) Tensioning: While welded fence panels are rigid, rolls of mesh must be properly stretched using a tension bar to prevent sagging. 4) Fasteners: Use high-quality tension bands, brace bands, and ties that match the coating of the mesh (e.g., galvanized fittings for galvanized mesh) to prevent galvanic corrosion.

5. Can you explain "shear strength" at the weld points?

Shear strength refers to the amount of force required to break the weld at the intersection of two wires by sliding them past each other. It is a direct measure of the quality of the weld. A high shear strength, as specified in standards like ASTM A185, ensures that the mesh maintains its grid pattern and structural integrity under load or impact. A weak weld can fail, causing the mesh to unravel and lose its strength, which is a critical failure in security or reinforcement applications.

6. What is the significance of the ASTM A185 standard for welded wire fabric?

ASTM A185 ("Standard Specification for Steel Welded Wire Reinforcement, Plain, for Concrete") is a critical industry benchmark. It dictates the minimum requirements for key properties of welded wire fabric used in concrete reinforcement, including wire diameter, mesh spacing tolerances, and, most importantly, the minimum weld shear strength. Specifying and using mesh that conforms to ASTM A185 provides engineers and contractors with the assurance that the material will perform as expected in a structural capacity.

7. How do I choose the right mesh opening for my application?

The mesh opening (or aperture) is as important as the wire gauge. The choice depends entirely on the function:

Containment/Exclusion: The opening must be smaller than what you're trying to contain (e.g., small animals) or exclude (e.g., pests). 1/2" or 1/4" galvanized hardware cloth is common for this.
Security: Anti-climb welded fence uses small rectangular openings (e.g., 3" x 0.5") that prevent finger and toe holds.
Flow & Visibility: Larger openings (e.g., 2"x2" or 4"x4") are used when air or light passage is important, such as in machine guards or general-purpose fencing.
Concrete Reinforcement: 6"x6" is a common size to allow for proper concrete aggregate flow and embedding.
