The total of the coronavirus-impact is still unknown, and might take years to fully analyze. What's clear right now is the impact to metal production—specifically steel. As this crisis unfolds, metal manufacturers will need to heighten their ability to forecast demands from the building sector (we're already battling the automotive, oil and gas industries as well).
Industries that were deemed non-essential for a period of time reduced the demand for steel. The construction industry, with most jobsites shut down, was part of this halt in demand. Producers of metal require long leads to idle and restart their mills, which presents more significant challenges.
