look at the key design considerations when you’re specifying a conveyor for indoor vs. outdoor service
AspectIndoor ConveyorsOutdoor Conveyors
Environmental Exposure• Controlled temperature/humidity• Full exposure to sun, rain, wind, snow
• Minimal exposure to dust and rain• Wide temperature swings
• UV degradation risks
Structural Materials• Standard steel (painted or powder-coated)• Galvanized or 316 stainless steel
• Mild stainless steel in wash-down zones• UV-stabilized plastics and seals
Protection & Enclosure• Usually open-frame; guards per safety code• Must include full weather covers or enclosures
• Sealed junction boxes and cable trays (IP66+)
Foundations & Supports• Mounted to existing floor or mezzanine• Engineered footings or piers to resist frost heave
• Light steel or modular frames• Heavy-duty supports to withstand wind loads
Drive & Controls• Standard AC drives in protected control panels• Drives in weatherproof enclosures (NEMA 4/4X)
• 24 V controls often in pull-out cabinets• Heaters or coolers inside enclosures for extreme temps
• Remote-mountable operator stations
Material Handling• Product flow largely uninterrupted by weather• Must guard against wind-blown debris, water ingress into product
• Convey through ducts or cleanrooms• Incorporate drip pans, grate-type cleats, or wash-off zones
Thermal Expansion• Minor spans; standard belt-tracking adjustments• Long runs require expansion joints and take-up designs to absorb length changes
Maintenance Access• Easy overhead or side access• Platforms, catwalks, fall protection for roof- or elevated conveyors
• Minimal PPE required• Weather-rated ladders and handrails
Safety & Compliance• Guards per ISO 13857 or OSHA• Additional lightning-protection grounding
• Standard emergency stops• Slip-resistant walkway surfaces if platformed
• Local building codes for outdoor structures
Power & Utilities• Wired through building infrastructure• UV-resistant cabling
• Cable trays inside walls• Conduits or trenching to protect feed from elements
Corrosion Control• Occasional clean-and-paint cycle• Regular anti-corrosion coatings or sacrificial anodes
• Routine inspection for rust and seal integrity

Top Design Tips

  1. Material Compatibility
    Outdoor belts & components should be rated for UV and wide temperature ranges.
  2. Ingress Protection (IP) Rating
    Specify IP66+ for drives, sensors, and junctions used outdoors.
  3. Drainage & Wash-Down
    Outdoor conveyors need drip rails, sloped frames, and easy-drain pans to avoid water pooling.
  4. Environmental Controls
    In very cold climates, include belt-heaters or enclosures; in hot climates, shade panels or cooling fans.
  5. Modular Expansion
    Design in pre-engineered expansion joints and adjustable supports to accommodate seasonal shifts.
  6. Maintenance Planning
    Factor in more frequent inspections and protective-gear requirements for outdoor personnel.

By tailoring materials, enclosures, foundations, and protective systems to the operating environment, you’ll ensure reliability, safety, and longevity—whether it’s in a climate-controlled hall or out under the open sky.
