FAQs: Technical and Specification Guidance

1. What is the typical material grade for discount annealed black iron wire?

The wire is usually produced from Q195 or SAE1006 low carbon steel, guaranteeing ductility and ease of drawing as required by ISO 16120/ASTM A510 standards.

2. How are wire diameters specified and what is the tolerance?

Wire diameters range from 0.5mm to 5.0mm nominal, with a tolerance of ±0.03mm as determined by micrometer or laser gauge inspection (EN 10218 standard compliance).

3. Are there certification or batch test documents supplied?

Yes, each batch is issued with a mill test certificate indicating tensile strength, elongation (%), and chemical composition per EN/ASTM/ISO standards.

4. How does black annealed compare to galvanized for fence weaving?

Annealed wire offers higher elongation for easier weaving, increased softness, and is typically used as the core in chain link and welded mesh before any galvanization or PVC coating.

5. What installation tools are recommended?

For construction or fencing, discount tie twister tool and discount twister rebar tool improve speed and uniformity during rebar tie-down or mesh installation.

6. What packaging forms are available for OEM fence suppliers?

Standard coils of 25kg/50kg, jumbo coils (up to 800kg), spools, or custom paper/plastic-wrapped rolls. OEM branding is available.

7. What corrosion/rust resistance is expected, and how is it enhanced?

Standard surface (annealed) is more susceptible outdoors but can last 3+ years in dry climates. Extended life is achieved with galvanization or PVC overcoating.
