Servicing The Palm Oil Industry Since 1982

About Us

Why take chances?

GA EXPERTISE is ready with the experience and know-­how to get your plant designed or upgraded and up and running from start to finish. We invite worldwide clients to consider our extensive, longstanding qualifications as a premier provider of engineering and construction solutions.

Four decades of know­-how

GA EXPERTISE benefits from over 40 years of hands on involvement in the design, construction, and operation of oil mills worldwide. The principals of the company have built an enviable reputation throughout the Far East, Latin America, and Africa for installing efficient, profitable, environmentally conscious mills.

Broad areas of expertise

The company enjoys broad­based capabilities, including engineering and feasibility studies, plant design and construction, onsite maintenance and operation, and export marketing studies. GA EXPERTISE, through a global network of strategic partners, offers an extensive range of solutions from unit process to true turnkey.

A reputation for quality

The firm has a proud success record in Mexico, Central and South America, the Caribbean, and Africa. As a result of intensive preconstruction planning and careful coordination with governmental and regulatory agencies, GA EXPERTISE projects go on stream quickly and within budget. Because we plan for the inevitable contingencies beforehand, we have immediate, working solutions based on our extensive experience.

It’s no coincidence that our mills typically outperform the industry average for productivity, profitability, and interruption-free operation.

We focus on what we do best

Because the firm only works in the vegetable oil industry, we bring you specific, relevant expertise in an area we thoroughly understand. This means that the designs and solutions we bring to the table make economic sense while adapted to the special needs of diverse geographic locations. In fact, a major fabrication affiliate has been certified by the American Society of Mechanical Engineers (ASME) and has built the first ever ISO/9000 certified palm oil mill in the world.
