Continental Trading Corp. supplies secondary black annealed carbon steel wire sourced from North American mills at wholesale prices. Annealed wire is carbon steel wire that has been heat-treated — heated to a specific temperature and then cooled slowly — to relieve internal stress, soften the metal, and improve ductility. The process produces a characteristic dark, blackened surface from which the product takes its name.
Our secondary annealed wire is material that did not meet a specific prime order — commonly due to surface appearance, diameter variation, or overproduction. The annealing itself is complete and the wire performs to specification for the vast majority of end uses.

Who Buys Second Choice Black Annealed Wire?
Black annealed wire is a high-volume consumable product, and the buyer profile for second choice material reflects this. Agricultural baling operations — hay, straw, and silage producers — are among the largest consumers of annealed baling wire in the world. For these buyers, the wire is used once and discarded. Price sensitivity is high, and the ability to substitute second choice annealed wire for prime without any change in performance is a meaningful cost advantage over a full baling season.
Construction tie wire buyers represent another major segment. Rebar tiers — contractors and subcontractors tying reinforcing steel for concrete pours — consume large quantities of soft annealed wire. The work requires wire that is soft enough to twist easily by hand or with a rebar tying tool, and second choice annealed wire that meets basic diameter and softness requirements is fully suitable for this application.
Recycling operations — cardboard compactors, plastic baling facilities, and scrap metal processors — use annealed wire extensively. These operations require large volumes of affordable wire with no requirement for appearance or tight specification. Second choice annealed wire is an ideal fit. Distributors serving these markets across Asia and Latin America are among our most consistent annealed wire buyers.
Sourcing & Availability
Black annealed wire is produced by annealing (heat treating) drawn low carbon wire in large batch or continuous processes. Second choice annealed wire arises when material falls outside the specification of a specific prime order — typically due to tensile range, surface appearance, coil weight, or minor diameter variation. The annealing process itself is complete, and the softness and ductility that define annealed wire are present in the material.
Continental Trading Corp. sources annealed wire from major North American wire producers. Availability tends to be consistent because annealed wire is produced in large volumes by multiple mills. Common gauges — 16 gauge through 10 gauge — are the most frequently available. Coil formats vary: loose coils, machine-wound coils, and spool-wound wire are all sourced depending on the lot.
This product ships cost-effectively in containers to buyers in South and Southeast Asia, Latin America, and the Middle East. If you are a regular buyer of annealed baling or tie wire, contact us to discuss your volume and gauge requirements. We will notify you as matching inventory becomes available.
Properties & Specifications
Black annealed wire is low carbon (typically C1006–C1018) and low tensile. Its key properties are softness, flexibility, and ease of forming. It is not galvanized, so it does not have inherent corrosion resistance — this is intentional, as the applications for annealed wire typically prioritize workability over weather exposure. Diameters typically range from 16 gauge to 8 gauge (1.6mm–4.1mm), available in coils or on spools.
Applications
Black annealed steel wire is the primary material for baling wire, tie wire, binding wire, and agricultural wire. It is widely used in construction (rebar tying), farming (hay bale binding), and packaging. Its softness makes it easy to twist and cut by hand. Industries including agriculture, construction, recycling, and general manufacturing rely on it daily.
Pricing & Availability
Secondary annealed wire trades at a meaningful discount to prime. Lot sizes vary. Contact us with your diameter, quantity, and target tensile and we will respond with available offers.
