Insteel Closes Ohio Steel Wire Facility Shifting Regional Reinforcement Supply
Insteel is closing its Ohio welded wire facility by October, concentrating production and changing regional delivery routes.
Steel Wire Rods
Material Specification
Hot-rolled semi-finished steel coils with circular cross-sections serve as the primary raw material for drawing into cold-finished wire, fasteners, springs and structural reinforcement mesh. Mills produce steel wire rods through continuous high-speed rolling of heated billets followed by controlled cooling on moving conveyor lines. Chemistry classifications divide production into low-carbon grades for welding wire and nails, medium-carbon grades for industrial fasteners, and high-carbon grades for prestressed concrete strands and tire cords.
Mechanical Behavior
Microstructural uniformity, scale morphology and tensile strength depend strictly on the cooling rate applied during the continuous conveyor process. Processing steel wire rods into fine wire requires mechanical descaling or acid pickling followed by successive reductions through carbide drawing dies. Surface defects such as seams, laps or decarburization layers cause wire breaks during rapid cold-drawing operations.
High-carbon grades require controlled in-line thermal treatment to achieve fine pearlite structures that withstand heavy plastic deformation without cracking. Tight dimensional tolerances on coil roundness and diameter prevent uneven die wear in downstream fastener heading machines.
Tariff Exposure
International shipments of coiled rod face frequent anti-dumping investigations, countervailing duty actions and safeguard quota restrictions across major importing jurisdictions. Mill test certificates detailing chemical heat analysis, yield strength and coil weight accompany each bill of lading to verify customs tariff classifications and origin criteria.
