Apex Engineering, PLLC is a full-service engineering firm headquartered in Calvert City, Kentucky. Apex was incorporated in 1974 to provide multi-discipline engineering services for industrial clients. Our clients include major producers of specialty chemicals, polymers, refrigerants, nonferrous metals, coal, aggregates, electric power generation, rubber, elastomer products, and pulp and paper manufacturers. From small engineering tasks to large-scale design/build projects, Apex Engineering provides unsurpassed quality resources to our clients. As a result, Apex has established continuing client relationships that have lasted over 40 years. Apex Engineering’s continued success is attributed to long-term, confidential relationships achieved through quality management, fast response and engineering excellence. The resulting trust is the backbone of these successful partnerships. In 1988, Apex established a regional engineering office in Mt. Vernon, Indiana.

In 1995, Apex Engineering established a subsidiary, Apex Controls Specialists (ACS). ACS is a dedicated entity concentrating on controls and related services. This gives Apex a one-stop opportunity for our clients and allowed for more seamless, efficient projects. In 2000, Apex used this synergy to develop Apex Modular Extrusion™ Systems, as well as, other process design/build systems.
