Product description

Rebar, also known as reinforcing steel, is an essential component in construction, commonly used in bridges, buildings, skyscrapers, homes, warehouses, and foundations to enhance the strength of concrete structures. Uncoated reinforcement bars (coiled, spooled, straight; deformed or smooth) primary function is to reinforce concrete, which is naturally weak in tension, by leveraging the tensile and compressive strength of steel, as defined by the Concrete Reinforcing Steel Institute (CRSI).

The surface of rebar is often patterned to form a better bond with concrete and can be epoxy-coated at CMC Epoxy-Coating Fabrication facilities to mitigate corrosion under certain environmental conditions. Similar to fabrication, this can occur at a number of epoxy-coating fabrication facilities. In order to represent the epoxy-coating fabrication process, two representative facilities were averaged and used as a proxy for fabrication.

Interpretation

For epoxy-coating fabricated rebar products, the impact assessment results indicate Module A1, i.e. raw materials including unfabricated steel product, is the key contributor to environmental impact categories including global warming potential, acidification potential, smog formation potential, eutrophication potential, and abiotic resource depletion potential of fossil energy resources. Module A2, i.e. transport to the fabrication facility, is not the most significant contributor to any impact category. Module A3, i.e. fabrication, is the key contributor to ozone depletion potential.
