Pulp & Packaging

High Tensile Galvanized Baling Wire for Pulp and Cotton Packaging (2.0–4.0 mm)

Diameter range: 2.0 mm – 4.0 mm
Common sizes: 2.3 mm and 3.0 mm
Zinc coating: 210–275 g/m²
Tensile strength: 950–2150 MPa depending on diameter
Packing: Coil/Spool, 300–1000 kg per unit

Our hot-dip galvanized baling wire is designed for pulp and cotton packaging applications. With a diameter range of 2.0 to 4.0 mm and tensile strength up to 2150 MPa, this high-performance wire offers excellent strength, surface uniformity, and corrosion resistance. Ideal for pop-baling, recycling, and paper industry use, it is packed in coils or spools ranging from 300 to 1000 kg per unit. Coated with high-purity zinc and conforming to ASTM and JIS standards, the wire ensures reliability in demanding baling operations.

Standards, certificates & inspection

Produced to your tensile, diameter and finish specification, with a mill test certificate per batch. Every batch is produced under an ISO 9001 quality management system and can ship with a mill test certificate covering diameter, tensile strength and zinc-coating weight. Third-party or pre-shipment inspection (SGS, BV or customer-appointed) is available on request.

See test reports & inspection and quality control & testing for the full documentation.

Frequently asked questions

Can I order a custom diameter, coating and tensile grade?

Yes. Zhongbo manufactures to your specification — wire diameter, zinc-coating weight, tensile grade, temper and finish. Send your requirement and we will confirm what we can produce.

Do you provide samples before a bulk order?

Yes. Samples or small initial quantities are available so you can evaluate diameter tolerance, coating, tensile strength and surface quality before placing a larger order.

Which standards do you manufacture to?

ASTM A641, EN 10244-2, BS EN 10257, JIS G 3547, AS/NZS 4534 and GB/T, or your own customer standard and test plan.

What is the minimum order quantity and lead time?

MOQ and lead time depend on the diameter, coating and quantity. Send your enquiry with the destination port and we will confirm both with the quotation.

Do you provide mill test certificates and third-party inspection?

Yes. Each shipment can include a mill test certificate covering diameter, tensile strength and zinc-coating weight, with SGS, BV or customer-appointed inspection on request.
