Industrial & Specialty Wire

Galvanized Steel Wire for Nail, Staple and Fastener Forming (1.2–2.5 mm)

Diameter range: 1.2–2.5 mm (Zhongbo legacy range)
Wire feedstock for selected nails, staples, pins and formed fasteners — not a guarantee that every geometry forms from it
Forming grade, surface and coating matched to your heading, bending, cutting and point-forming process
Pre-galvanized or form-then-galvanize routes discussed so coating mass/adhesion stays acceptable after forming
Precision spool winding for continuous machine feed

Made to order to your diameter, coating, tensile grade and standard — request a quote for price, minimum order quantity and lead time.

This is wire feedstock for fastener forming — not a guarantee that every nail or staple geometry can be produced from it. Your forming method, upset ratio, bend radius, cutting, point forming and coating-damage tolerance determine the grade we recommend. Some fasteners are formed from uncoated wire and galvanized afterward, while others use pre-galvanized feedstock; we ask you to identify the process so we can confirm whether coating mass and adhesion remain acceptable after forming. Approved grades are defined by fastener type and diameter and then validated for cracking, bend, upset and coating adhesion on your machine.

Available	OEM / ODM / manufacture to drawing, subject to technical review
Transport Package	Precision spools/reels or coils sized for fastener-forming equipment
Trademark	Zhongbo Steel
Origin	Xinzheng, Henan, China
HS Code	Confirmed by material, finish, cross-section and destination
Production Capacity	Confirmed with the quotation

Tensile Strength

Confirmed feedstock runs about 800–1150 MPa, split into approved grades by fastener type and diameter and validated on your equipment. Lower-carbon grades may need a different tensile/ductility window than staple wire, and we add elongation, reduction-of-area or practical heading/bend tests where you control them.

Features

Diameter and mechanical grade tailored to the fastener-forming process
Controlled surface and coating for cutting, bending and heading
Precision spool winding for continuous machine feed
Low-carbon grade options subject to forming trials
Custom coating mass and wire condition by order
Trial reels and batch traceability

Packaging & Shipping

We publish reel dimensions and net weights by machine type; you provide flange, barrel, traverse, bore, winding direction and maximum pay-off tension. Coating and spool flanges are protected from handling damage.

Precision steel, plastic or wooden reels
Reels to the confirmed net weight and machine format
Coils for suitable straightening/forming equipment
Palletized or crated export reels

Use cases

Selected nail-forming operations
Staple and pin manufacture
Small fasteners and wire-formed hardware
Pre-galvanized feedstock where the coating survives the approved forming process

Who it is for

Nail and staple manufacturers, fastener plants, wire-forming companies and hardware suppliers that qualify feedstock on their own machines.

Standards, certificates & inspection

ASTM A641/A641M covers general galvanized carbon steel wire and includes supplementary requirements for wire from which nails and staples are formed; we cite the ordered standard and class after confirming size, coating and temper. We do not imply that pre-galvanized wire suits every nail process. 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

Should nails be made from pre-galvanized wire?

It depends on the fastener and process — send the finished-fastener drawing, machine type and coating requirement so forming damage can be evaluated.

Which tensile grade is suitable?

We confirm an approved, size-specific grade through machine trials rather than quoting one broad range.

Can you supply zinc-aluminum coated nail wire?

Only where coating adhesion and finished-fastener performance are validated.

Can you match my reel?

Yes, once we have the reel drawing and target net weight.
