Industrial & Process Facilities

When industrial operations need mechanical work done right — safely, precisely, and without excuses — they call John F. Pennebaker Co., Inc.
Industrial projects leave zero room for mistakes. Downtime is expensive. Tolerances are tight. Safety is non-negotiable. And mechanical systems must perform under real-world load, not just look good on paper.
That’s exactly where we excel.
We support industrial facilities across Georgia with heavy-duty mechanical and process piping solutions built to run reliably, day after day, shift after shift.

What We Build for Industrial Clients
Process Piping Systems
Steam, hydronic, chilled water, hot water, condensate return, compressed air, chemical lines, and more. Fabricated in our shop, installed with precision in the field.
Mechanical Equipment Installations
Chillers, boilers, cooling towers, pumps, heat exchangers, industrial ventilation systems, and custom assemblies sized for real industrial loads — not “typical office” conditions.
Plant Upgrades & Shutdown Work
We know how to plan and execute critical-path work during tight turnarounds and shutdowns. When the clock is ticking, our crews deliver.
Design-Assist & BIM Execution
We model everything in Revit + SysQue, clash it in Navisworks, coordinate with the GC and trades, and deliver field-ready spool drawings that let our installers move fast and install with confidence.
Fabrication-Driven Field Efficiency
Our shop builds high-quality spool pieces, assemblies, and specialty piping runs so our crews spend less time cutting, threading, and improvising in the field — and more time installing.

Why Industrial Clients Choose Us
Because We Don’t Miss
We hit our dates. We hit our targets. And if there’s a problem, we fix it — not blame someone else.
Because Safety Matters
Our crews work clean, stay sharp, and follow strict safety protocols. Industrial environments demand discipline, and we bring it every day.
Because You Need a Contractor You Don’t Have to Babysit
Owners and GCs trust us because we communicate clearly, coordinate proactively, and deliver exactly what we promise.
Because Our Work Stands Up to Real Loads
We install systems that hold pressure, deliver flow, reject heat, and keep your operation running.

Ready to Talk? So Are We.
If you operate a plant, distribution center, energy facility, or industrial process environment, we want to hear from you.
We understand the stakes — and we know how to deliver when it counts.
