Advantages of 4mm Galvanised Wire

1. Superior Mechanical Property Balance: The 4mm diameter strikes a balance between strength and workability, meeting most structural fastening and support requirements while retaining excellent ductility and toughness for easy bending and shaping.

2. Flexible Corrosion Protection Levels for Diverse Applications: Hot-dip galvanized wires feature thicker zinc coatings, while electrogalvanized wires have thinner coatings. High-zinc coatings suit humid environments, while low-zinc coatings are ideal for dry conditions.

3. Mature Process with Controllable Costs: As a mainstream specification, 4mm galvanized wire is produced using continuous drawing combined with batch galvanizing. This scaled, standardized production significantly enhances efficiency.

4mm Galvanised Wire Applications

The diameter and strength characteristics of 4mm galvanized wire enable it to meet load-bearing requirements while offering processing flexibility, making it suitable for diverse industrial applications, such as:

• Construction and Engineering: Used for concrete reinforcement; manufacturing chain-link fencing, farm fencing, and safety barriers; securing scaffolding.
• Agriculture and Horticulture: Vineyard/orchard support; poultry cages and fencing; securing greenhouse films and structures.
• Industrial and Manufacturing: Serves as binding material; used in wire mesh fabrication (e.g., mining screens, filtration nets); manufacturing coat hanger frames, storage bin frames, etc.
• Crafts and Decor: Ideal for creating wrought iron plant stands, Christmas ornaments, and craft frameworks; constructing garden trellises, storage racks, and similar projects.

FAQ about 4mm Galvanised Wire

Q1: What weight can 4mm galvanized wire support?

A: When vertically suspended as a single strand, 4mm galvanized wire has a safe load capacity of approximately 80-120kg. Actual load-bearing capability depends on factors like mounting method, usage environment, and load type. It is fully adequate for suspending grape arbors or agricultural crops.

Q2: What precautions should be taken for long-term storage of 4mm galvanized wire?

A: Store in a dry, well-ventilated environment. Elevate large coils to prevent ground moisture corrosion. Electrogalvanized wire should not be stored long-term—limit storage to 3-6 months.

Q3: How can hot-dip galvanized wire and electrogalvanized wire be distinguished?

A: Hot-dip galvanized wire has a dark silver-gray surface with a rougher texture. Electrogalvanized wire features a bright silver-white surface that is smooth and free of visible imperfections. A simple test involves scraping with a knife: the thicker hot-dip coating resists exposure of the base material.
