Bare copper wire buyers in North and South Carolina
Bare copper arrives in every form a plant produces it: grounding electrode conductor cut out of a service upgrade, hard-drawn loops off a utility yard, and bright soft-drawn scrap coiled in a bucket. Each is reviewed on its own terms.
- Soft and hard drawn
- Solid and stranded
- Bare, tinned, scrap
Bare copper is the oldest conductor on any industrial site and the one most often mis-sorted. It comes out of a switchgear room as grounding electrode conductor, off a pole line as hard-drawn tie wire, and out of a motor shop as short bonding jumpers in a coffee can. Soft-drawn wire bends in the hand. Hard-drawn wire fights back, because it was tempered for overhead tension rather than for pulling through conduit.
The distinction matters at the buying desk. Soft or annealed copper, made to ASTM B3 and stranded to ASTM B8, is what grounding and bonding work consumes, and it is what distributors stock on reels from 14 AWG solid up to 4/0 stranded and beyond. Hard-drawn copper belongs to overhead line work and to applications that need tensile strength, and it is priced against a different market than building wire scrap.
We buy both, along with tinned bare copper from older switchboards, bare ground rings, and clean cut-offs off a contractor’s wire rack. What we do not do is treat a bucket of mixed bare copper as a known quantity. The review starts with what the wire is, then moves to how much of it there is. A tagged reel is a different asset from a coil in a bucket, and the difference is not the metal.
What we buy in this family
Condition and documentation decide the basis, not the family alone. These are the forms this material usually arrives in.
- Bare soft-drawn copper, solid and stranded
- Hard-drawn copper line and tie wire
- Tinned bare copper from older gear
- Grounding electrode conductor cut-offs
- Bare copper ground ring and grid
- Clean bright copper jumper scrap
- Full reels with tags and footage
What decides the basis on a bare copper lot
Two questions settle most of it: is the temper known, and is the footage documented. A reel of soft-drawn 2/0 with a manufacturer tag and a footage mark is a length somebody can install, and it is reviewed as material. The same weight cut into six-foot tails is scrap, and it is reviewed as scrap.
Tinned, corroded, buried: condition that changes the review
Tinned copper is not a defect. It was specified for damp locations, for marine work and for older switchgear, and a clean tinned conductor is still conductor. What hurts it is green corrosion between the strands, which means moisture has been sitting inside the wire for a long time.
Buried bare copper is the harder case. A ground ring pulled out of Piedmont clay arrives with soil packed between the strands, sometimes with the remains of exothermic welds attached, and always with an unknown amount of conductor lost to corrosion. We will look at it, but it is recovery material and we say so at the start.
Footage, coil weight and the evidence we ask for
Photographs do most of the work before anyone drives anywhere. A reel gets photographed with its tag legible, its flange intact and something in frame for scale. A coil gets weighed on a scale reading in pounds, with the figure visible. Where there is no tag, conductor diameter and coil weight let us estimate, and the estimate is labelled as one.
Where this cable turns up in the two states
Across the Piedmont, bare copper leaves buildings rather than arriving at them. A service upgrade in a Gaston County mill village produces grounding electrode conductor in three or four sizes. Substation work in Duke Energy territory or on a co-op system produces bare jumpers, ground grid conductor and the short tails that never make it back into shop stock. Coastal plain utility yards hold hard-drawn copper because the overhead plant out there has been rebuilt more than once.
In the Research Triangle and along the Charlotte data hall corridor south of the airport, the bare copper is smaller and cleaner: bond jumpers from racks, tray bonding, cut-offs from grounding busbar work. Upstate South Carolina automotive plants generate the same families in larger sizes, because their service entrances carry the ampacity that calls for 4/0.

Bare copper wire questions
Is tinned bare copper worth less than bright copper?
Not automatically. Tinning was a deliberate specification for damp and corrosive locations, and a clean tinned conductor is reviewed as conductor. The question is what sits under the plating. Green corrosion between strands, black oxide, or soil packed into a buried ground ring all point to metal that has already been consumed, and that changes the basis rather than the description.
Do you buy bare copper by the pound or by the foot?
It depends on the form. Documented lengths on a tagged reel are reviewed by size and footage because they can go back into service. Loose coils, short tails and heavily oxidised material are reviewed by weight and by how clean the copper is. Send photographs and a weight, and we will tell you which basis applies before anything is loaded.
How is a grounding electrode conductor sized?
NEC Table 250.66 sizes the grounding electrode conductor from the largest ungrounded service conductor. It is a table rather than a formula, so an 8 AWG minimum sits at the bottom and larger services call for 2/0, 3/0 or 4/0 copper. Service upgrades are where most surplus grounding conductor comes from, and it usually arrives in more than one size.
Can you take bare copper that came out of the ground?
Yes, with the understanding that it is recovery material. Buried conductor carries soil, corrosion product and sometimes remnants of welds or clamps, and the original cross-section may be reduced where corrosion has worked. It is still copper and still worth reviewing, but it is not priced as clean bright wire and we will not describe it as such.
