Hey there! I totally understand the need for a sturdy trash can in an apartment courtyard - those areas really take a beating from both residents and the elements. Based on my experience managing our own building's common areas, you'll want to look for specific features that ensure longevity.
For true durability, I'd recommend checking out commercial suppliers rather than typical home improvement stores. Companies like Rubbermaid Commercial Products and Continental Commercial are specifically engineered for high-traffic areas. Their products typically feature heavy-duty materials like powder-coated steel or structural foam that can withstand weather extremes and potential vandalism.
Look for models with secure, locking lids to prevent animals from getting in and consider ones with reinforced bases that won't tip over easily. Metal cans with welded seams tend to last longer than plastic ones in my experience, though high-quality polyethylene options can be excellent too if they're thick enough.
Many suppliers offer direct purchasing online, but I'd also suggest contacting local restaurant supply companies or commercial janitorial distributors in your area. They often carry inventory you can inspect in person and may offer better pricing for bulk purchases if your building needs multiple units.
The key is investing in commercial-grade rather than residential-grade products - they cost more upfront but save money long-term by not needing frequent replacement. Our building switched to commercial bins three years ago and we haven't had to replace a single one since!
