Cold Rolled Flat Steel Wire Strips

In the field of metal wires, round steel wire and irregularly shaped steel wire meet different industrial needs with their differentiated properties. Round steel wire, thanks to its uniform cross-sectional design, ensures stable mechanical performance transmission, combining high precision with strong corrosion resistance; irregularly shaped steel wire, on the other hand, breaks through traditional structural limitations with its unique cross-sectional shape, providing customized solutions for precision manufacturing and special assembly scenarios.

core advantage

Circular steel wire: precise and reliable, suitable for all scenarios

Uniform mechanical properties: using high quality carbon steel, stainless steel or alloy steel as the base material, through precision cold drawing process to control the section roundness error less than or equal to 0.01mm, tensile strength covers 500-3000MPa, can withstand dynamic load and alternating stress, to ensure the stable performance in key components such as automobile suspension spring, bearing ball, etc.

Mirror surface treatment: after multiple cold drawing and polishing processes, the surface roughness reaches Ra≤0.1μm, effectively reducing the friction coefficient, reducing wear and loss, extending service life, suitable for high precision transmission and sealing scenarios.

Comprehensive environmental protection system: provide multiple protection schemes such as galvanizing, copper plating and PVC coating, pass ISO 1461 salt spray test, meet the long-term corrosion resistance requirements in harsh environments such as Marine engineering and outdoor infrastructure.

Abnormal steel wire: customized section, unlocking structural innovation

Infinite shape possibilities: support standard shapes such as square, hexagon, flat, triangle, etc., as well as complex non-standard structures such as Z-shaped, toothed, wavy, etc., to accurately match the high integration design requirements of electronic chip lead frame, miniature spring contacts, etc.

Process precision guarantee: advanced processes such as precision rolling and cold bending are used to achieve high precision control within the dimensional tolerance of ±0.02mm, ensuring the consistency of mass production and meeting the assembly requirements of auto seat adjustment rack, medical device skeleton and other components.

Performance and space optimization: The design of different cross sections can effectively improve the utilization rate of materials and the mechanical properties of structures. For example, flat steel wire can achieve a balance between lightweight and high strength, which is suitable for scenes that optimize both space and function, such as car seat belt clips and building decorative frames.

General advantages: green manufacturing, rapid response

Environmental compliance production: strictly follow the RoHS and REACH directives, adopt low-carbon manufacturing process, ensure that the products are safe and harmless, and meet the global market access standards.

Flexible customization service: provide one-stop customization solutions from material selection (carbon steel, stainless steel, alloy steel), surface treatment (coating, coating) to hardness adjustment and winding mode. It supports small batch quick sample making and shortens the product development cycle.
