              Ameron to Construct Fiberglass Pipe Plant

    PASADENA, Calif.--(BUSINESS WIRE)--March 26, 2004--Ameron
International Corporation (NYSE:AMN) today announced plans to
construct a fiberglass-composite pipe plant at the Company's
wholly-owned subsidiary's facilities in Malaysia. The new plant would
provide fiberglass-pipe manufacturing capacity to support the growth
of the Company's Asian operations in Singapore and Malaysia.
    The investment would total approximately $12 million and would
include acquisition of land adjacent to the subsidiary's existing
fiberglass fittings operation, construction of a 55,000 square-foot
building, and design and construction of a 40-foot filament-winding
machine. The equipment will be designed by Ameron's Research and
Engineering Center, utilizing state-of-the-art technology. When
completed, the new Malaysian plant will be the most advanced
fiberglass-pipe facility in the industry. The filament-winding machine
will more than double production and improve operating efficiencies
compared to conventional methods by significantly increasing glass
rovings application speeds. In addition, the winder can be easily
upgraded to manufacture Ameron's latest fiberglass-composite pipe
products under development, such as Sand Core Fiberglass Pipe and
Bondstrand(R) Steel-Strip-Laminate Pipe (SSL(TM)). The new plant is
expected to be operational by September 2005.
    Ameron's wholly-owned subsidiaries in Singapore, Ameron (Pte)
Ltd., and in Malaysia, Ameron (Malaysia) Sdn Bhd, serve the
Asia-Pacific region for fiberglass-composite pipe in a broad range of
markets. The primary markets include marine, offshore, oilfield,
chemical and industrial. The market for fiberglass-composite pipe
continues to expand as new applications are developed,
fiberglass-composite pipe gains greater acceptance, and as the
Asia-Pacific regional economy grows.
    James S. Marlen, Ameron's Chairman, President and Chief Executive
Officer, stated, "Our fiberglass-composite pipe business in Asia has
been very successful, and this expansion will provide the production
capacity needed to support continued growth and, importantly, to
continue the high level of service our customers deserve."
