What's the real difference between a $150 big-box filing cabinet and a $400 commercial one?

The price gap reflects real quality differences. Budget cabinets (big-box store range) use thin steel gauge (24–26 gauge), lighter-duty drawer slides that wear out or bind over time, basic lock mechanisms, and often have thinner powder-coat finishes that chip more easily. Commercial-grade cabinets use 18–22 gauge steel, full-extension ball-bearing drawer slides rated for thousands of open/close cycles, better lock cores, and more durable finishes. In a home office used occasionally, a budget cabinet may last fine. In a commercial office opened and closed 20+ times a day by multiple users, budget cabinets deteriorate within 2–5 years. Commercial-grade cabinets from FindOfficeFurniture.com are built to last 15–20 years — call 888-719-4960.
