Exhibit 99.1

    Ameron Reports Stronger Second-Quarter Operating Performance


    PASADENA, Calif.--(BUSINESS WIRE)--June 21, 2007--Ameron
International Corporation (NYSE:AMN) reported earnings of $15.8
million, or $1.74 per diluted share, in the second quarter ended May
27, 2007. In the second quarter of 2006, net income totaled $18.7
million, or $2.11 per diluted share, and included a nonrecurring,
pretax gain on the sale of property of $9.0 million. Excluding
property sales, second-quarter results were higher in 2007 than in
2006 as a result of the improved operating performance of continuing
operations.

    Earnings per diluted share from continuing operations, which
excludes the Performance Coatings & Finishes business that was
divested in 2006, were $1.63 in the second quarter of 2007, compared
to $1.94 per share, including the gain on the property sale, in the
second quarter of 2006. Income from discontinued operations, after
taxes, was $.11 per diluted share in the second quarter of 2007,
compared to $.17 per diluted share in the second quarter of 2006.
Sales totaled $156.8 million in the second quarter of 2007, compared
to $132.7 million in the second quarter of 2006.

    For the six months ended May 27, 2007, earnings per diluted share
totaled $2.68, compared to earnings per diluted share of $2.53 for the
six months ended June 4, 2006. Earnings per diluted share from
continuing operations were $2.55 for the six months ended May 27,
2007, compared to earnings per diluted share of $2.38, including the
pretax property sale gain of $9.0 million, for the six months ended
June 4, 2006. Income from discontinued operations, after taxes,
totaled $.13 per diluted share for the six months ended May 27, 2007,
compared to $.15 per diluted share for the six months ended June 4,
2006. Sales for the six months ended May 27, 2007 totaled $277.1
million, compared to $258.6 million for the six months ended June 4,
2006.

    The Fiberglass-Composite Pipe and Infrastructure Products Groups,
as well as TAMCO, Ameron's 50%-owned steel mini-mill, had improved
operating results in the second quarter of 2007. The Water
Transmission Group had higher sales, but income was lower in the
second quarter of 2007, compared to the second quarter of 2006, due
primarily to start-up costs associated with the wind-tower production
and delayed water pipe orders.

    "The performance of our continuing operations increased
substantially in the quarter and the first half," stated James S.
Marlen, Ameron's Chairman, President and Chief Executive Officer. "The
Company's strong performance trend continues, and, given the generally
favorable market conditions and the anticipated improvement in the
Water Transmission Group, we should achieve solid results in the
second half of 2007."

    The Fiberglass-Composite Pipe Group had higher sales and segment
income in the second quarter of 2007, compared to the second quarter
of 2006. Sales improved 32%, as all operations worldwide experienced
increased demand due to the continued strength in core markets,
primarily the marine, offshore, chemical and industrial segments.
Onshore oilfield piping demand remained steady at historically high
levels. The increase in segment income totaled $6.6 million, or 66%,
reflecting the higher sales volume, plant efficiencies and favorable
product/market mix. The outlook for the Fiberglass-Composite Pipe
Group remains positive.

    The Infrastructure Products Group had higher sales and segment
income in the second quarter of 2007, compared to the second quarter
of last year. Both the Hawaiian and the Pole Products Divisions had
improved performances. Sales increased $4.8 million, or nearly 10%,
while segment income improved $2.5 million, or 33%. The Hawaiian
Division achieved higher sales on both Oahu and Maui and across all
construction sectors, with the exception of residential. Pole
Products' sales improved slightly in both the steel pole market and
the decorative concrete lighting pole market. Orders for residential
lighting products in the key Southern California and southeastern U.S.
markets moderated during the second quarter. The overall construction
markets served by the Hawaiian and Pole Products Divisions are stable,
although the residential construction markets have slowed. The outlook
for the Infrastructure Products Group remains steady.

    The Water Transmission Group had higher sales of $5.4 million in
the second quarter of 2007, compared to the second quarter of last
year. The sales increase was driven by Ameron's entry into the market
for large-diameter wind towers, offset somewhat by lower sales of
water transmission pipe and protective linings. Segment income was
lower than in the second quarter of last year. The continued softness
of the water infrastructure market in the West and delays of ongoing
projects were the primary reasons for the lower water transmission
pipe sales. While the anticipated recovery of the water transmission
pipe market has started, the recovery is slower than anticipated.
Overall, the outlook for the Water Transmission Group is for a
continued robust wind-tower market, with the water pipe markets
improving steadily.

    TAMCO had continued earnings growth, while sales were slightly
less in the second quarter of 2007, compared to the second quarter of
2006. Ameron's share of TAMCO's net income totaled $4.2 million after
taxes, compared to $3.8 million in the second quarter of 2006. For the
six months ended May 27, 2007, TAMCO's sales increased 19%, while
Ameron's share of TAMCO's net income increased from $4.6 million to
$9.3 million, net of taxes. The demand for steel rebar in the western
U.S. region remains strong due to a high level of commercial and
highway construction. Market dynamics remain positive, and metal
spreads reflect the strong business conditions. The outlook for TAMCO
remains favorable.

    James Marlen concluded, "On balance, business and market
conditions remain favorable worldwide, and we anticipate that our
businesses will continue to deliver strong results in 2007."
