Import Bead Wire — Buy in Bulk from Supplier in China

Henan Summary Holdings Co., Ltd. produces bead wire for tire reinforcement, specifically targeting passenger car, bus, and heavy-duty vehicle tire applications. The wire is drawn steel with high tensile strength and corrosion-resistant coating, though the supplier does not list exact grade, diameter range, or coating chemistry in the available profile. The product functions as a bead bundle wrapped around the tire rim seat to anchor the tire to the wheel. Typical bead wire for automotive use conforms to standards such as ASTM B452 or EN 10244, but buyers must confirm which standard this supplier follows and request mill test certificates for chemical composition and mechanical properties.

The manufacturing process for bead wire involves hot rolling of steel rod, patenting for microstructure control, mechanical descaling, dry drawing through tungsten carbide dies, and final coating with brass or bronze for rubber adhesion. Tensile strength for tire bead wire typically ranges from 1,700 to 2,200 MPa depending on diameter and grade. Common diameters span 0.78 mm to 1.65 mm for passenger tires and up to 2.00 mm for truck and bus tires. The brass coating weight is typically 3-6 g per square metre per side, with copper content 63-68%. Henan Summary Holdings mentions corrosion and wear resistance but does not specify salt spray test hours, coating adhesion, or rubber penetration values, so buyers should request these metrics.

Primary customers are tire manufacturers and retreaders supplying OEM and replacement markets. The automotive OEM sector demands IATF 16949 quality system certification and full traceability from melt to shipment. Aftermarket buyers may accept lower documentation but still require consistent diameter tolerance and wire break performance. The supplier mentions ISO and CE compliance but does not state certificate numbers or scope; verify these directly. Incoterms mentioned include FOB and CIF, with implied shipment from Chinese ports such as Qingdao or Shanghai, though the exact loading port is not stated. Payment terms, MOQ, and lead time are absent from the profile and must be negotiated.

Henan Summary Holdings Co., Ltd. is located on Jinshui Road, Zhengzhou 450008, Henan Province, central China. The supplier holds an imported tier classification and harbor trust tier, with zero response rate and zero average response hours recorded on the platform. This indicates no active messaging history through the channel, so buyers should establish direct contact via email or telephone to assess communication capability and English-language technical support. Henan is a significant base for Chinese steel and wire products, which provides plausible industrial context for this product line.

The company profile does not disclose establishment year, plant area, annual capacity, number of production lines, or export destinations. No specific ISO certificate numbers, IATF 16949 automotive approval, or customer references appear in the data. The supplier describes itself as a manufacturer, but buyers should verify production capability through factory audit or video inspection, particularly for steel wire drawing and heat treatment equipment. Given the critical safety nature of tire components, automotive buyers should treat unverified claims with caution and conduct full supplier qualification before approving the vendor for production material.
