Platinum Equity LLC said Thursday that it has signed a definitive agreement to purchase SCM Metal Products Inc. from Gibraltar Industries Inc. for an undisclosed amount.

SCM, which is based in Research Triangle Park, N.C. and has plants in China, makes and distributes copper-based powder and pastes for the metallurgy, chemical, electronics and industrial markets.

“SCM is a market leader with a strong customer base and an experienced management team, and its parent company is divesting the business to focus on other core operating segments,” said Jacob Kotzubei, the Platinum Equity partner who led the transaction.

SCM is the latest in a series of investments Platinum has made in the industrial and metals services industry. Last October, it sold ESM Group, which supplies products and services to the steel industry, to SKW Metallurgie following an acquisition and turnaround. It is in the process of reorganizing Ryerson Inc., a large metals service center provider, which it acquired last October.

Platinum Equity is the Los Angeles-based investment vehicle of billionaire Tom Gores.
