33111

Analysis

NAICS 33111 is the 2022 NAICS industry for iron and steel mills and ferroalloy manufacturing, part of 3311 (Iron and Steel Mills and Ferroalloy Manufacturing).

It has only one more detailed code, 331110, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 359 US establishments in this code in 2023, employing 78,532 people at an average annual payroll of $116,063 per employee (90th percentile of national industries). 32% of the establishments have fewer than five employees, which is close to the national mix.

Between 2018 and 2023 the number of establishments fell 19% and employment fell 11%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
