Conveyors built to your line speed.
Every conveyor we build is engineered around your product, footprint, and throughput — not pulled off a shelf. Frames, drives, guarding, and UL-508A controls all come out of a one-stop shop in Joliet, Illinois.
A conveyor is only as good as how it matches the rest of the line. We size belt and roller widths to your product, set drive speeds to your rate, and pick frame materials for your environment — dry, wet, or full washdown. Then we wire and program the controls so the section runs in step with the equipment around it.
Conveyor types.
Six core conveyor styles, each suited to a different job on the floor. Most lines combine several.
Modular Plastic Belt
Interlocking plastic belt that handles curves, inclines, and accumulation. The workhorse for food, bakery, and packaging lines that need a positive-drive, easy-to-clean surface.
Powered Roller
Driven rollers move cases, totes, and trays with zone control and accumulation. Common in fulfillment, palletizing infeeds, and anywhere boxes need to queue without back pressure.
Slider / Belt Bed
A flat belt riding on a steel slider bed for small, light, or irregular product that would fall between rollers. Smooth, quiet transport for bagged goods and loose parts.
Vertical Lift
Raises or lowers product between floor levels or mezzanines without giving up floor space. Used to feed packaging from production below or move cases up to palletizing.
Right-Angle Transfer
Pop-up belts or chains move product 90 degrees to merge, divert, or change direction in tight floor plans. Keeps lines compact where a curve will not fit.
Robotic / Cobot-Tended
Conveyors paired with FANUC robots or collaborative cobots for pick-and-place, case loading, and palletizing. We handle the integration, guarding, and safety logic end to end.
Built here, not bought.
Frames, drives, and guarding fabricated and assembled on our own floor in Joliet — so the conveyor that ships is the one we engineered.

Why STI conveyors.
Built around your product and supported by the same people who designed them.
- Built to your product, speed, and footprint — not a catalog size.
- Stainless, aluminum, or painted-steel frames for your environment.
- VFD and gearmotor drives for repeatable, adjustable line speeds.
- Sanitary and washdown options for wet and high-care areas.
- Integrated UL-508A controls, wired and programmed in-house.
- Fabricated, tested, and supported under one roof in Joliet, IL.

Common questions.
The questions plant engineers ask us most.
What are typical lead times for a conveyor?
It depends on the build. Lead times are quoted with your proposal — and because we quote our own shop capacity, they’re numbers we stand behind. Because we engineer, fabricate, and wire in-house, we hold the whole schedule and can give you a firm date with the quote.
Can you build washdown and sanitary conveyors?
Yes. For wet and high-care areas we build stainless 304 or 316 frames with open tubular construction, sloped surfaces that drain, tool-less belt removal, and IP-rated drives and devices. We spec belting and lubricants suitable for the wash chemistry and frequency your sanitation crew runs.
Can you retrofit into an existing line?
Often, yes. We field-measure the existing line, match transfer heights and belt speeds to the equipment upstream and downstream, and design the new section to drop into your footprint. We can tie into existing controls or add a section panel that talks to your PLC, and we schedule installation around your production windows.
Do you handle controls and installation too?
Yes. Our UL-508A panel shop wires the controls, our programmers write the PLC and HMI logic, and our crew handles installation, startup, and operator training. One company is responsible from the drawing through the day your line runs, so there is no hand-off and no finger-pointing.
