30 Year Anniversary


It all began in 1986 when Mr. Leslie T. Stewart CEO embarked on a journey to develop control systems to support the glass industry. Stewart Engineers was founded in Gross Ile, Michigan. For several years, they have served customers in the control system industry. As the team worked closely with these clients, they saw more and more business opportunities in the glass industry. This led to an expansion in their team for the development of float innovative technology specifically for the float glass industry.


Early in the 1990's, Stewart Engineers designed its first StewartFloat® tin bath. The first StewartFloat® was installed and successfully commissioned in Indonesia. Towards the end of that project, Andrew Stewart, now President of Stewart Engineers, signed on to work for the company as a Controls System Engineer.

After successfully commissioning over 20 StewartFloat® tin baths, Andrew Stewart relocated the Stewart Engineers headquarters and all of its employees to Wake Forest, North Carolina. Andrew then led the design of the AcuraCoat® On-Line chemical vapor deposition (CVD) glass coating system and was promoted to President of Stewart Engineers. He has steered the team in the successful commission of three turnkey glass manufacturing facilities, over 20 custom StewartFloat® tin baths, five AcuraCoat® on-line glass coating systems, and over 100 other glass industry related projects.

Our latest world class turn-key glass manufacturing project is Orda Glass, located in Kyzylorda, Kazakhstan.

  • 600 MTPD
  • 2-12 mm glass thickness
  • Producing export quality architectural glass
  • CVD coated glass products:
    • Low E

Stewart Engineers is the Technology Provider and Partner, EPC contractor, Project Manager, and responsible for all product guarantees. The Orda Glass complex will be ready for production in 2019 and is expected to house the latest and best technology to date.

Stewart Engineers is a leader in the Glass Industry and has a presence on nearly every continent. The growth of Stewart Engineers in this challenging economy is largely due to the investments in innovative technology advancements, the authority to provide technology licensing, all while offering the highest quality products at competitive prices.

Stewart Engineers would like to take this opportunity to express its appreciation to all clients, suppliers, and business partners for their continued support and commitments over the years. We look forward to new opportunities and continued work in this great industry.
