What is Spoke Wire? Why is it so crucial?

High-Tensile Galvanized Spoke Wire

Spoke Wire is the core raw material for manufacturing spokes in bicycles, motorcycles, tricycles, and other vehicles. It is not ordinary steel wire; its properties directly determine the strength, durability, fatigue resistance, and overall performance of the final wheel. A high-quality Spoke Wire is crucial for maintaining structural integrity and safety when the wheel endures dynamic loads and impacts.
As a professional Spoke Wire manufacturer, we fully understand your requirements for supply chain stability and product consistency. Every roll of Spoke Wire we provide represents our commitment to exceptional quality.

Core Product Parameters: Professional, Precise, Customizable

Spoke Wire Product Specifications: All parameters can be customized according to your drawings and requirements.

Parameter Category	Detailed description
Material Specifications	Premium high-carbon steel (e.g., SWRH 42A, 45A, 52A, 55A+), 72A piano steel wire, strictly compliant with international standards such as JIS G3502 and ASTM A228.
Tensile strength	The range spans from 1600 MPa to 2200+ MPa, meeting the diverse strength requirements of bicycles ranging from everyday commuters to professional competition-grade models.
Surface treatment	1. Galvanized: Standard electrogalvanized finish (bright white/color zinc) provides excellent rust resistance. Our strictly controlled process ensures uniform coating and strong adhesion. 2. Stainless Steel: 304 or 430 grade offers superior corrosion resistance, ideal for high-end mountain bikes, road bikes, and harsh outdoor environments.
Diameter range	1.6mm to 3.0mm (15G to 8G), covering the vast majority of spoke specifications demanded by the market. Tolerances are strictly controlled within ±0.02mm to ensure production stability.
Tare Weight and Packaging	Standard coil weight: 20-25 kg per roll. Packaged with rust-proof paper + plastic film + reinforced wooden crates to ensure the Spoke Wire surface remains undamaged and unaffected by deformation during transportation.
Character	A. The use of round wire and SP linner casing, compression deformation, high transmission efficiency. B. The use of fused process to prevent the end of the tail loose and rust, and make the core line smooth.
Standard	ISO 9227:2006,DIN 50021:1988,ASTM B117-03,JIS,etc
Packaging	Usually packing in 250m/roll,, 500m/roll, We also followed a definite package as per customer's requirement

Our Production Capabilities: The Solid Backbone of Your Reliable Supply Chain

Purchasing clients are not only concerned with the products themselves, but also with the manufacturer's production capacity, quality control systems, and consistent supply capabilities.

Advanced production lines:

We operate a fully integrated production line encompassing wire drawing, heat treatment, galvanizing, and precision layer winding.

Utilizing domestically advanced straight-through wire drawing machines ensures dimensional accuracy and surface finish of the steel wire.

Our fully automated electroplating production line employs computer-controlled current and duration to guarantee uniform coating thickness across every batch of Spoke Wire.

Rigorous Quality Control System:

Incoming Material Inspection: Conduct chemical composition and physical property analysis on each batch of wire rod.

Process Inspection: Perform online diameter monitoring, torsion testing, and repeated bending tests to ensure product stability during manufacturing.

Final Inspection: Each batch of Spoke Wire must pass final tensile strength testing, coating thickness measurement, and salt spray testing, accompanied by authoritative test reports.

Production Capacity and Delivery:

We possess robust manufacturing capabilities to handle large-volume, long-term stable orders.

With a mature raw material supply chain and inventory management system, we ensure timely delivery and respond to your urgent needs.
