Product description
Wire rod is a hot-rolled round produced in coil form that is approximately 2,600 lbs and is typically drawn into wire for use in a wide variety of construction and industrial applications, including tie wire, mesh, fencing, shelving, shopping carts, wire hangers, and nails. The approximate material content of carbon steel wire rod will vary slightly from batch to batch. In addition, wire drawn from rod can be galvanized, plated, and painted. Wire rod is packaged in coils, which average 1.5 tons. The coils are secured with steel banding that is wrapped around the coil. The length, weight, size, heat, and grade information are declared on a tag that is stud-welded or wire-tied to the coil. All CMC wire rod is manufactured from 100% recycled scrap steel sourced within the United States.
Interpretation
For unfabricated wire rod products, the impact assessment results indicate that Module A1, i.e. raw materials, is the key contributor to environmental impact categories for ozone depletion potential. Module A2, i.e. transport to the mill, is not the most significant contributor to any impact category. Module A3, i.e. manufacturing at the mill, is the key contributor to global warming potential, acidification potential, smog formation potential, eutrophication potential, and abiotic resource depletion potential of fossil energy resources.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
