                  NORTH AMERICAN GALVANIZING & COATINGS REPORTS
                      SECOND QUARTER 2004 RESULTS IMPROVED

           TULSA, OKLAHOMA, August 16, 2004 - North American Galvanizing &
Coatings, Inc. (AMEX-NGA) announced today an increase in sales, net earnings and
earnings per share for the second quarter of 2004. The Company's net sales for
the three months ended June 30, 2004 rose 11.1%% to $9,333,000 compared to sales
of $8,398,000 for the same quarter a year ago. Net earnings for the second
quarter of 2004 were $106,000, or $.01 per share, fully diluted.

           The Company's president and chief executive officer, Ronald J. Evans,
noted a continuation of the modest increase in construction-related demand for
galvanizing the Company experienced in the first quarter of 2004. Compared to
2003, the Company's increased earnings were primarily the result of improved
gross profit from cost efficiencies and higher volume and lower interest
expense, partially offset by additions to the reserve for collection of doubtful
accounts. For the same period a year ago, the Company reported a net loss of
$714,000, or $.11 per share, which included a $790,000 net loss related to the
closing of an abandoned galvanizing plant. Mr. Evans expressed confidence that
North American Galvanizing is positioned to take advantage of its streamlined
cost structure as the economy improves, and emphasized that the Company will
continue to address improving operating efficiencies.

           For the first six months of 2004, the Company reported that sales
increased 8.8% to $17,891,000 from sales of $16,438,000 for the same period of
2003. Net earnings for the first half of 2004 were $316,000, or $.04 per share
fully diluted, compared to a prior year first-half loss of $1,044,000, or $.15
per share, which included a $831,000 net loss for discontinued operations.

           The Company is a leading provider of hot dip galvanizing and coatings
for corrosion protection of fabricated steel products through its North American
Galvanizing Company subsidiary. The Company conducts its galvanizing and
coatings business through a network of plants located in Denver, Hurst
(Dallas/Fort Worth), Houston, Kansas City, Louisville, Nashville, St. Louis and
the Tulsa area. Hot dip galvanizing provides metals corrosion protection for
many product applications used in commercial, construction and industrial
markets. Our home page is: www.nagalv.com.
