WALNUT — TCI Manufacturing and Equipment Sales in Walnut will be hiring more employees after expanding the size of its business on Route 92, west of Walnut.

Mike Maynard, president of TCI, said the company was started in 2000 by a small group of shareholders to be a small conveyor manufacturing company that also designs and builds products for its customers — ranging from sand and gravel businesses to steel mills to quarries.

In 2007, the company built a 26,000-square-foot building over the top of the existing manufacturing building in order to keep the manufacturing operations going on during construction. Once the larger building was finished, the smaller one inside it was demolished.
