Trinity chairman Timothy Wallace said the move was being made in response to falling orders. In its Q2 results, the company said the order pipeline for wind towers in 2012 had fallen 7% to $817 million.
However, $413 million of the 2012 backlog is subject to a legal dispute with Suzlon over breach of contract. TSTI says it has supplied Suzlon with just $88.6 million worth since the two companies signed a supply agreement in 2008.
US tower manufacturers are struggling at the moment. Earlier this week, fellow US manufacturer DMI announced plans to close one of its factories and sell on another. While Vestas is cutting jobs at its Pueblo, Colorado plant.
Speaking about the plan to shift away from wind, Wallace said: "These initiatives will enhance our ability to meet market demand and achieve additional operating leverage in the future. As we shift a portion of our production capacity to pursue these opportunities, there are multiple variables that can influence the timing of events pertaining to quarterly financial results."
Trinity is a member of the US-based Wind Tower Trade Coalition, whose members also include DMI Industries, Katana Summit and Broadwind Energy.
