Continental Trading Corp. supplies secondary bright carbon steel wire in both high carbon and low carbon grades, sourced directly from major North American wire producers. Bright wire — also called bright drawn or cold drawn wire — undergoes cold drawing through dies to achieve precise diameter control and a smooth, clean surface finish.
Our secondary bright wire is wire that fell outside a specific customer order for reasons such as diameter tolerance, surface marks, or overproduction. In most cases the material is otherwise prime. Buyers consistently achieve significant savings versus ordering custom prime wire from a mill.

Who Buys Non-Prime Bright Carbon Steel Wire?
Bright carbon steel wire is one of the most widely purchased products in the industrial wire market, and the second choice segment reflects this breadth. Fastener manufacturers — producers of screws, bolts, nails, and rivets — are among our largest customers for bright wire. Cold heading grades (typically low-to-medium carbon) represent a consistent demand stream. For many fastener applications, the forming and mechanical performance of the wire is what matters, and second choice bright wire that meets the dimensional and tensile requirements of a cold heading application is fully suitable.
Spring manufacturers purchase high carbon bright wire for a wide range of coiled springs where the oil-tempering process of OT wire is not required. The hard-drawn temper of cold drawn bright wire provides sufficient elasticity for furniture springs, light industrial springs, and small mechanical components. Brush manufacturers and specialty fabricators round out the buyer profile, often sourcing second choice wire that would never have been considered if prime pricing were the only option.
Export buyers across Asia and Southeast Asia represent a significant portion of our bright wire volume. Markets where the price gap between prime and second choice wire is most meaningful — where margins are thin and input cost management is critical — tend to be the most active buyers of our non-prime material.
Sourcing & Availability
North American wire mills produce bright carbon wire to extremely tight tolerances as prime product. When a production run falls outside a specific customer's specification — whether due to diameter variation of a few thousandths of an inch, minor surface marks from the drawing die, or simply overproduction — the material is downgraded to second choice. The core drawing and metallurgical process is identical to prime.
We source bright carbon wire across the full range of carbon grades — from low carbon C1006 drawing wire through high carbon C1090 spring wire grades. Diameter range is broad: from fine wire under 0.5mm to heavy drawn wire over 10mm. Availability is lot-dependent and varies week to week. The most consistently available sizes tend to be those produced in the highest volume by North American mills.
Because bright wire is produced in such high volumes, second choice lots arise regularly. Buyers who register their diameter range, carbon grade, and quantity target with Continental Trading Corp. receive offers promptly when matching material is available. Contact us to register your interest.
High Carbon vs. Low Carbon Bright Wire
High carbon bright wire (C1045–C1090+) offers high tensile strength — typically 1,600–2,200 MPa — and is used for springs, wire rope, tire reinforcement, fasteners, and instrument strings. Low carbon bright wire (C1006–C1022) is softer, more ductile, and suited for forming, welding, mesh, and general fabrication. Diameters typically range from 0.008” to 1.25” (0.2mm–32mm).
Applications
Bright steel wire is one of the most versatile wire products in industrial manufacturing. It is used to produce fasteners (screws, bolts, nuts, rivets), springs, wire rope, wire mesh and welded fabric, wire forms and baskets, coat hangers, brush bristles, musical instrument strings, and bead wire for tires. The list of applications is virtually endless, which makes this our highest-volume product.
