Ameron International Corp. on Thursday beat Wall Street expectations by reporting a 50 percent jump in fiscal third-quarter earnings.

The Pasadena maker of steel products for the chemical and energy industries reported net income of $8.9 million (96 cents a share) for the quarter ended Aug. 29, compared with $5.9 million (64 cents) a year earlier. Revenue rose 2 percent to more than $134 million. Analysts surveyed by Thomson Reuters on average had expected per-share earnings of 84 cents on revenue of $131 million.

“We are pleased by the third-quarter profitability, especially given difficult market conditions,” Chief Executive James S. Marlen said in a statement. He noted that sales growth in its water transmission and infrastructure products unit was offset by a decline in net revenue from the company’s larger fiberglass-composite pipe business.

Shares were up $1.01, or 1.6 percent, to $64.05 in midday trading on the New York Stock Exchange.
