Custom Steel Fabrication of an Industrial Process Structure for the Refrigerant Industry

Industrial Process Structure
Industrial Process Structure

A customer in the refrigerant industry contracted TMI Contractors for the custom fabrication of an industrial process structure expansion. This consisted of multiple floors of structural steel, galvanized grating and floor plate, handrails, ladders, and stairs. TMI expanded upon the customer supplied engineering designs with professional structural detailing and 3D modeling.

All required steel components were precision cut, drilled, and formed at our state-of-the-art facility utilizing a range of equipment while maintaining tight tolerances of +0 and -1/16" throughout. 530,000 pounds of structural steel was furnished for this project, in a number of material shapes including steel W shape beams, I beams, channels, plates, pipe, angles, and round bar. Serrated bar grating was also used. The floor plate and grating was galvanized for longevity and corrosion protection, and all handrails and ladders were finished with a 2-coat paint system of epoxy and urethane, furnished in OSHA stipulated safety yellow.

Our quality assurance protocol dictates the 100% complete inspection of all members. Testing procedures included a layout and dimensional check, visual weld inspections, ultrasonic weld tests, and blast profile readings. Painted items were tested for quality with WFT and DFT coating thickness measurements along with performing temperature, dew point, and humidity readings 3 times per shift. Field erection took place in southeastern US, with the aid of a prepared 3D model. The project was complete within 3 months, a rapid turnaround time attributed to our ability to perform the detailing, fabrication, and finishing work in-house. The finished structure measured 68' in length and 50' in width, and was 7 stories tall.
