WATER TRANSMISSION GROUP:

Ameron is a leader in pipe technology and a principal supplier of highlyengineered concrete and steel pipe systems in the western United States and Canada. American Pipe & Construction International ("APCI"), a wholly-owned subsidiary, is a principal supplier of concrete and steel pipe products in Colombia. An affiliate, Ameron Saudi Arabia, Ltd. (30%-owned) manufactures concrete pipe in Saudi Arabia and through a joint venture in Egypt.

Designed to satisfy the widest range of performance requirements, Ameron concrete and steel pipe products provide long-term conveyance for water and wastewater. Typical services include high-pressure and gravity water transmission and distribution lines, inverted siphons in aqueducts, sewer force mains, cooling water systems for power plants, sewer outfalls, storm drains, culverts, tunnel liners and penstocks in hydroelectric generating plants.

Primary Ameron product lines include heavy-wall steel pipe and concrete pressure pipe in diameters up to 12 feet for high-pressure and medium-pressure applications, as well as reinforced concrete pipe products for low-pressure and gravity-flow services. Complimenting these product lines, Ameron also specializes in steel fabrication for the energy and transportation markets with products such as large-diameter pilings and wind towers.

Ameron's Protective Linings Division manufactures and markets T-Lock® and Arrow-Lock®, polyvinyl chloride sheet linings that have been protecting concrete pipe and cast-in-place concrete structures worldwide from the corrosive effects of sewer gases, acids and industrial chemicals for more than 50 years. Proven T-Lock® technology is also used in Ameron's new T-Hab® system for rehabilitating large-diameter sewers without excavating city streets. Arrow-Lock® is rapidly gaining acceptance as the long-life alternative for the rehabilitation of wastewater structures and manholes.

FIBERGLASS-COMPOSITE PIPE GROUP:

Ameron manufactures and markets the world's most comprehensive line of fiberglass-composite pipe products under trademarks such as Bondstrand®, Dualoy®, PSX®, Centron®, SSLT, and LCXT, for applications in the chemical and industrial, oilfield, fuel handling, offshore and marine market segments. Ameron fiberglass pipe is a cost-effective alternative to corrosion-prone metallic piping and non-reinforced thermoplastics. Ameron fiberglass pipe is particularly well suited for industrial services and chemical processing because of its corrosion resistant properties and ability to withstand higher temperatures and pressures than thermoplastic materials.

The use of fiberglass piping in secondary containment and waste-handling applications continues to grow in response to increasingly stringent regulation of groundwater contamination as a result of corroded metallic piping. Responding to environmental risks resulting from usage of corrodible metal piping, Ameron continues to provide gasoline service station operators with the latest technology, such as Bondstrand LCXT, a coaxial, double-wall fiberglass pipe system.

Ameron serves the offshore oil-production market with a wide range of lightweight, corrosion-resistant piping products, including Bondstrand PSX® fire-resistant piping. Bondstrand corrosion-resistant piping is also used to combat highly aggressive environments in the marine industry. Ameron's large-diameter polyester pipe provides corrosion-resistant properties to solve operating problems in markets such as chemical, power generation, water and wastewater.

Centron International, Inc. ("Centron"), a wholly-owned subsidiary, serves the worldwide oilfield market with small-diameter, high-pressure fiberglass pipe for applications such as downhole tubing, oil flow lines, water injection lines and secondary recovery systems.

Ameron's proprietary Bondstrand Steel-Strip-Laminate pipe (SSLT) combines the proven corrosion resistance of fiberglass with the strength of steel. With these features, SSLT pipe provides a superior solution compared to metallic alternatives for high-pressure, highly-corrosive oilfield applications.

INFRASTRUCTURE PRODUCTS GROUP:

Ameron's Infrastructure Products Group consists of two domestic businesses.

Ameron's Pole Products business supplies spun-cast concrete streetlight poles and bollards along with steel traffic and lighting poles to customers throughout the United States.
