One Roof in Fenton, Missouri
Born out of engineering expertise and passion for efficient design, GAT was founded by the current owner's grandfather in 1958 in St. Louis, Missouri, and was at the forefront of industry change in the 1960s, innovating and creating patented technology and processes.
Today the same team that quotes your line designs it, welds it, installs it, and starts it up — single-source accountability from consult to daily production, all under one roof in Fenton, Missouri.
We've always had a strong focus on family and our employees — people come to work for GAT and stay an average of 16 years.

“We outsource our coating, and it's eating our margin.”
Should you bring finishing in-house? The honest make-vs-buy framework — break-even volume, payback period, and a published 26–32-week timeline.
The make-vs-buy framework →“Our line is old — or we're out of capacity. And we can't stop production.”
Retrofit vs. replace, and staged cutovers that install in segments without full shutdown. Three documented projects.
Modernize or expand your line →“Our finishing line is the bottleneck.”
Lines engineered to your takt time, not a catalog SKU — including a documented 40% cycle-time gain from direct-impingement ovens.
Find your real bottleneck →“Our powder-coat quality is inconsistent.”
Cure problems usually start in the oven: ±5 °F temperature uniformity, verified on 9-point SAT testing.
Diagnose your quality inconsistency →“Our line can't meet VOC limits.”
Powder coating has no solvents and no VOCs. GAT converted Tracker Marine's wet line to a three-color powder system that fell well within limits.
Your VOC-compliance options →“Our curing oven's energy bill is too high.”
A 16-ft infrared tunnel replacing a 40-ft convection oven recorded a 30–40% fuel reduction — one of four levers that cut oven fuel cost.

Every component is engineered, fabricated and tested in our Fenton, MO facility.
The washer that will save you money and decrease downtime during production
Polypropylene is the difference maker when it comes to washers. Whether it's a batch washer, industrial washer, parts washer, mesh belt washer, or barrel washer, your best bet is starting with GAT's PolyPro washer.
- What It Does
- Multi-stage pretreatment cleaning
- Why It's Better
- Chemical-proof housings, 10-year anti-corrosion warranty
The perfect solution for wet paint or powder coat needs
Our GAT Batch Ovens are factory pre-fired and tested, with a 150–500 °F operating range. Standard delivery takes 6–8 weeks and can be expedited.
- What It Does
- Flexible cart-loaded curing
- Why It's Better
- Pre-fired at factory, 150–500 °F operating range
Whether you need powder coating, wet paint, or low-temperature curing, we have the right process oven for you.
Our GAT engineering team streamlined our production of process ovens to include six-inch-thick insulated oven panels, high-velocity air seals, floor-mounted ductwork, and FM, UL, and NFPA-compliant gas train utilized on the gas-fired heaters.
- What It Does
- Continuous-flow curing (convection & IR)
- Why It's Better
- 6" insulated panels, patented air-seal, NFPA-compliant gas trains
Rapid ramp rates and targeted heat zones in a compact footprint
GAT's electric short-wave and gas catalytic infrared ovens handle flash-off, pre-gel, and full cure, running 50–70% shorter than comparable convection ovens. One documented replacement — a 16-ft IR tunnel in place of a 40-ft convection oven — recorded a 30–40% fuel reduction.
- What It Does
- Rapid-ramp curing (short-wave, medium-wave & catalytic IR)
- Why It's Better
- <2-min powder flow at 375 °F, ±5 °F uniformity, elements swap in under 15 min
Uniform heat at production speed with direct-impingement airflow
Gas-fired convection ovens for powder coating, e-coat, and liquid paint at up to 90 feet per minute. Six-inch mineral-wool panels and patented air-seal vestibules hold ±5 °F across the belt, documented on 9-point SAT testing per AMS2750.
- What It Does
- Continuous flash-off, dry-off & full cure
- Why It's Better
- 45% fewer panel seams, 15% average gas savings vs. legacy recirculating ovens
Focus on efficient movement and optimal layouts
From overhead conveyors (which comprises about 90% of our work) to mesh belt, chain and crossbar, wicket, drum and batch conveyors, GAT can design and install a solution that works perfectly for your company.
- What It Does
- Move parts through the line
- Why It's Better
- Overhead, power-and-free, mesh-belt, wicket & more, all PLC-controlled
Cost-effective insulated powder enclosures that maximize your system performance
GAT Powder Coating Rooms are designed to fulfill your specific job requirements, including environment-controlled powder storage areas. GAT understands the importance of maintaining a clean, climate controlled powder coating area for spray coating applications.
- What It Does
- Clean, climate-controlled spray environment
- Why It's Better
- Modular enclosures sized to your booth & reclaim goals
Three Lines, Three Problems Solved
Tracker Marine
Replaced a wet paint line that had reached VOC limits with a system engineered for three-color powder application — and you can watch the line run.
The Tracker Marine story →Setina
Modernized an in-house finishing line: obsolete controls out, PLC automation in.
The Setina story →Santa Rosa Systems
Added finishing capacity for a growing manufacturer without stopping production.
The Santa Rosa Systems story →- Remote PLC support connects you to a GAT engineer in minutes
- Firm supplier pricing — final cost rarely varies more than ±3% after contract
- 30/30/30/10 payment terms: you pay as the line proves itself
Bring two numbers. Leave with an answer.
A free, no-obligation consultation: bring your annual volume and what you pay your coater per part, and GAT's engineers will tell you whether an in-house line pays for your operation — and if it doesn't yet, we'll say so.

The Differences Between E-Coating vs. Powder Coating
A Manufacturing Decision-Maker's Guide. E-coating (electrocoating) uses electrical current to deposit liquid paint onto metal parts, while powder coating uses an electrostatic charge.
Curing and Drying Ovens: How Temperature Uniformity Impacts Film Performance
When you're making films, the ovens you use for curing and drying really matter. It's not just about getting things dry; it's about how the heat is distributed.
Made in Missouri: How Our Fenton Facility Controls Quality from Steel to Startup
You know, it's pretty cool to think about how things are made, especially when it's right here in our own backyard. Our facility in Fenton, Missouri controls the whole process.
