Business Editors

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."
