About Henan Hengxing PC Steel Product Co., Ltd - Steel Wire Supplier in China

China is the origin of Henan Hengxing PC Steel Product Co., Ltd, which lists 182 active products in its catalogue. The company focuses on steel wire products, including hot‑dip galvanized wires, high‑tensile steel cords for radial tyres, ultra‑fine diamond and glass cutting wires, and specialised wires for solar wafer cutting. Most items fall under HS chapter 72, primarily HS 7217 series for steel wire and HS 7229 for coated steel wire, reflecting standard tariff classifications for these materials. The material specifications include hot‑dip zinc coating at 99.99 % purity, carbon contents ranging from 0.6 % to 0.95 %, and brass or copper alloy coatings for certain grades. Product descriptions also indicate wire diameters from 0.1 mm to 4.77 mm and tensile strengths up to 1860 MPa for PC strands.

The catalogue also contains items outside the core steel wire range such as silicon wafer cutting wires, polycrystalline solar wafers, and building material PC strands, each assigned HS codes 7229.20, 7229.90, and 7312.10 respectively. The steel cord listings specify configurations such as 0.315+6×0.3 mm HT or 3×7×0.2 mm HE, indicating standard tyre reinforcement constructions. Brass‑coated and copper‑plated variants are described with material notes like “Brass Coated Carbon Steel” or “Low‑Carbon Steel Core with Electrolytic Copper Coating”. The product set reflects typical offerings of Chinese steel wire manufacturers that serve tyre, construction, solar and precision cutting markets.

Product Range and Specialties of Henan Hengxing PC Steel Product Co., Ltd

The product list covers hot‑dip galvanized steel wire (HS 7217.20) with zinc coating grades of 99.99 %, high‑carbon steel wires for ultra‑fine cutting (HS 7217.10) and brass‑coated variants (HS 7217.30). Cord configurations for radial tyres are presented in HT (high‑tensile) and HE (high‑elongation) grades, matching industry designations such as ISO 9004‑2 for tyre reinforcement. Coated cutting wires for glass and solar wafers appear under HS 7217.90 and HS 7229 series, where brass or copper plating is used to reduce friction and improve wear resistance. In addition, PC strand steel for post‑tensioning and building applications (HS 7312.10) is listed with tensile grades of 1860 MPa, comparable to ASTM A1035 specifications. Typical industry grades for these categories include ASTM A108 for carbon steel wire, IEC 60228 for conductor class, and ISO 9355 for coated wire performance. Buyers will also encounter standard dimensions such as 0.1‑0.3 mm diameters for wafer cutting wires and 12.7 mm strand diameters for construction steel.

Trade and Export Information - Henan Hengxing PC Steel Product Co., Ltd

Exporters of hot‑dip galvanized steel wire from China usually ship to automotive tyre manufacturers in Southeast Asia, Europe and the United States, where HS 7217.20 is classified under the “Steel wire, rods, bars, profiles and sections, hot‑dip coated”. Solar wafer cutting wires (HS 7229.20) are in demand by photovoltaic module assemblers in Germany, the United States, Japan and emerging markets in India, with buyers often requiring CE marking and compliance with IEC 61215 for related equipment. Post‑tensioning PC strands (HS 7312.10) are commonly exported to construction projects in the Middle East and Africa, where tensile‑strength certification and third‑party test reports are standard. Typical certifications requested by importers include ISO 9001 quality management, CE conformity for coated products, and RoHS compliance for brass‑coated wires. Shipping is normally arranged in 20‑ft or 40‑ft containers, with wire coils packed on wooden pallets or in bulk steel drums, and Incoterms such as FOB or CIF are frequently used. Customs authorities often inspect coating thickness and carbon content against the declared HS code, so accurate material data sheets are essential.

Sourcing from Henan Hengxing PC Steel Product Co., Ltd - Buyer Guidance

When sourcing these steel wires, buyers should request a mill test certificate that details carbon percentage, tensile strength, elongation, and coating thickness for each grade. For coated wires, a surface coating analysis (e.g., zinc or brass thickness measurement) and a corrosion resistance test are standard verification steps. Samples should be evaluated against industry standards such as ASTM A108 for carbon steel wire and IEC 60228 for conductor class, with particular attention to diameter tolerance (±0.01 mm for ultra‑fine wires). Buyers are advised to confirm that the supplier can provide ISO 9001 certification or equivalent quality system documentation, as well as any CE or RoHS declarations required by the destination market. Clarifying the minimum order quantity - often expressed in metric tonnes per grade - and the typical lead time of 30‑45 days helps align production scheduling with project timelines.

What wire diameters are available for solar wafer cutting applications?

The catalogue lists diameters from 0.1 mm to 0.3 mm for brass‑coated and copper‑coated solar wafer cutting wires, all classified under HS 7217.10 or HS 7229.20.

Which HS code covers the hot‑dip galvanized steel wire?

Hot‑dip galvanized steel wire is listed under HS 7217.20, the tariff heading for steel wire, hot‑dip coated with zinc.

What tensile strength can be expected from the 12.7 mm PC strand?

The PC strand is specified with a tensile grade of 1860 MPa, comparable to ASTM A1035 high‑strength steel strands.

Are brass‑coated cutting wires suitable for glass cutting?

Yes, brass‑coated high‑carbon steel wires (HS 7217.90) are commonly used for glass cutting due to their low friction and wear resistance.

What certifications should I ask the supplier to provide?

Typical requests include ISO 9001 quality management, CE conformity for coated products, and RoHS compliance, as well as mill test certificates for each wire grade.

What packaging format is used for bulk steel wire shipments?

Bulk shipments are usually packed in 20‑ft or 40‑ft containers on wooden pallets or in steel drums, with the coils securely banded to prevent movement.

What is the usual lead time for high‑tensile tyre cord orders?

Lead times are generally 30‑45 days from order confirmation, depending on the specific HT or HE grade and order volume.

How can I verify the coating quality of galvanized wire?

Request a coating thickness report and a corrosion resistance test; the zinc coating is specified at 99.99 % purity in the product description.
