From large 100 ton carbon steel heat exchangers to electropolished stainless steel windtunnel components, Pump barges shipped to Peru, cold boxes weighing over 150 tons, tanks and pressure vessels are all formed and fabricated in our shop, then assembled into pieces of a size that can be trucked or barged to the jobsite.

Functional design requires the integration of theoretical analysis with practical know-how. The growing trend toward design-build and project-management contracts recognizes this value. CAID is heavily involved in major industrial projects around the world and we look forward to contributing our design expertise to your demanding project.










“Whether you require our design expertise or only require fabrication to your existing plans CAID has the experience to make your project a success.”
