About GAT Systems

A History of Forward Thinking, Satisfied Clients and Long-Term Employees

Born out of engineering expertise and passion for efficient design, GAT was founded by the current owner’s grandfather in 1958 in St. Louis, Missouri.

From the beginning, we put our focus on creating custom finishing solutions and process lines for companies in North America.

GAT was at the forefront of industry change in the 1960s, innovating and creating patented technology and processes.

We’ve always had a strong focus on family and our employees, which is why people come to work for GAT and stay here for many years.

Why Should You Choose GAT Systems?

When is it time to stop outsourcing and build an in-house automated finishing system?

It starts with knowing how much you currently spend and how much throughput volume you may need in the future. Many manufacturers outsource some to all of their finishing, be it powder coating or liquid finishing, because they want to leave it up to “experts”.

Don’t think you have the space for a Custom Finishing System? The GAT Systems engineering team would like to help you run the numbers. “If there’s a better way to do it – the GAT engineering team is ready to earn the opportunity to help you define and validate it”.

The GAT Process for Custom Finishing Systems – your requirements assessment is designed to help “right-size” a finishing process by taking the production volume and physical dimensions of parts to be coated and calculating a conveyor line speed to meet these requirements. The goal here is to determine the total annual conveyor length necessary to process the volume of production parts for the target production goal, including future growth.

The GAT Systems relationship starts with our team investing in the required discovery with you, calculating answers to these questions by performing the GAT analysis of process specific information. Each of these analyses are discussed in the following sections.
