Röben has built a second plant at its American site in Clay County, TX. The US subsidiary Triangle Brick Company in Durham, NC, opened the fourth US. Röben plant there in 2016, near Henrietta and around 95 miles northwest of Dallas. It supplies around 100 million clinker bricks of the American "Modular Size" format per year.

Now, a second plant has been built at the same location, which will also produce around 100 million bricks. The kiln was fired at the end of April, and the first bricks were delivered in May. "The market in Texas is growing. Around 50% of all facades are made with clinker bricks, and the state's population is growing disproportionately," says Röben Managing Director Wilhlem-Renke Röben. One reason is that many large companies are moving from California, which is now overpriced, to Texas, including, for example, the e-car company Tesla.

The plant technology for the new factory was supplied by Direxa Engineering from Lakewood, CO, and the furnace was built by Herrop Industries from Columbus, OH. In total, the Röben subsidiary Triangle Brick already produces around 370 million units of "modular size" with its existing four plants, making it the fourth-largest clinker manufacturer in the USA and the largest privately owned brick company.
