That's an excellent question. For an industrial area, you need a trash can that can handle serious abuse, high volumes, and potentially harsh conditions. A standard municipal bin simply won't last. Based on your need for a "very heavy-duty" solution, I'd steer you firmly towards commercial-grade or industrial-specific models.
My top recommendation is a heavy-gauge galvanized steel or powder-coated steel bin. Look for a minimum of 12-gauge steel. This material is virtually indestructible, resists dents, withstands impact, and can handle all weather conditions. Avoid plastic for a true industrial setting—it can become brittle and crack.
Capacity is key. For high-traffic industrial zones, consider a minimum of 50 gallons, with 65 to 100-gallon wheeled carts being a very common and practical choice for maintenance crews. Ensure it has heavy-duty, full-swivel casters for easy movement even when full.
The lid is critical. A secure, hinged, and lockable lid is non-negotiable. It prevents scavenging, contains odors, and stops wind from scattering debris. A sturdy, foot-pedal-operated model can be helpful for workers with their hands full.
Finally, consider standardization. Choosing a model that fits your local waste collection truck's automated lift system (if used) will save immense labor. Brands like Toter, Rubbermaid Commercial, and Witt are industry standards for a reason—they're built to last for years under constant use.
In short, prioritize: Robust Steel Construction > High Capacity (65-100 gal) > Secure Locking Lid > Heavy-Duty Wheels. Investing in this level of quality upfront prevents constant replacement and keeps your industrial area cleaner and safer.
