Exhibit 99.1
                              Ameron Reports Strong
                             First-Quarter Results


    PASADENA, Calif.--(BUSINESS WIRE)--March 21, 2007--Ameron
International Corporation (NYSE:AMN) reported earnings of $.94 per
diluted share in the first quarter ended February 25, 2007, compared
to $.41 per diluted share in the first quarter ended March 5, 2006.
Earnings per diluted share from continuing operations, which excludes
the performance coatings and finishes business that was divested in
2006, were $.92 in the first quarter of 2007, compared to $.43 per
share in the first quarter of 2006. Income from discontinued
operations, after taxes, was $.02 per diluted share in the first
quarter of 2007, compared to a net loss of $.02 per diluted share in
the first quarter of 2006. Sales totaled $120.4 million in the first
quarter of 2007, compared to $126.0 million in the first quarter of
2006.

    The Fiberglass-Composite Pipe Group and TAMCO had outstanding
results, compared to the first quarter of 2006. The Infrastructure
Products Group's results were about even, in spite of the shorter
quarter in 2007; and the Water Transmission Group had lower sales and
a segment loss.

    "Overall, we are pleased with the solid first-quarter
performance," stated James S. Marlen, Ameron's Chairman, President and
Chief Executive Officer. "Business conditions remain favorable for
most of our operations, and we expect the Water Transmission Group to
improve later in the year."

    The Fiberglass-Composite Pipe Group's sales increased 27% in the
first quarter of 2007, compared to the first quarter last year, while
segment income improved 55%. The sales increase was driven by the
stronger demand in the marine, offshore and chemical and industrial
markets worldwide, while the onshore oilfield piping segment remained
steady. The increase in segment income was consistent with the higher
sales level. The outlook for the Fiberglass-Composite Pipe Group
remains favorable.

    The Infrastructure Products Group had slightly lower sales ($1.1
million) and segment income ($.1 million) in the first quarter of
2007, compared to the first quarter of 2006. Ameron's Hawaiian
Division had lower sales and income due to wet weather in Oahu and
Maui and fewer shipping days in the first quarter of 2007, compared to
the first quarter of 2006. The Pole Products Division had higher sales
and segment income in the first quarter of 2007, as market conditions
for decorative concrete lighting poles remained favorable in Southern
California and the targeted regions in the southeastern U.S.
Construction market conditions are stable, with the exception of the
residential construction market, which has slowed somewhat. The
outlook for the Infrastructure Products Group remains generally
favorable.

    The Water Transmission Group had lower sales in the first quarter
of 2007, compared to the first quarter of 2006. The sales decline of
$13.6 million was attributable principally to the continued softness
of the water infrastructure market in the western U.S., and project
delays on active orders for water transmission piping and production
delays related to large-diameter wind towers. The Group incurred a
segment loss of $3.7 million due to the low sales volume and
inefficient plant utilization. The cyclical slowdown in the water
infrastructure market is forecasted to turn late in the second quarter
with a number of major projects scheduled to bid. In addition, the
projects delayed in the first quarter are expected to be rescheduled
into later quarters. The outlook for the Water Transmission Group is
for a steady recovery during 2007 with improved year-over-year
performance.

    TAMCO had particularly strong sales and net income in the first
quarter of 2007, compared to the first quarter of 2006. The demand for
steel rebar in California, Nevada and Arizona remained strong due to
increased commercial and highway construction. Net income improved due
to favorable product mix, increased steel selling prices and improved
margins. Ameron's share of TAMCO's net income totaled $5.0 million
after taxes, an increase of $4.2 million from the first quarter of
2006.

    James Marlen concluded, "The first-quarter results represent a
good start for 2007. I expect we will continue to achieve strong
operating results throughout 2007."
