When designing or specifying a commercial round trash can for high-traffic environments like restaurants, offices, or public spaces, the internal diameter of the opening is a critical dimension. At our factory, we manufacture commercial round cans with a standardized internal diameter that typically ranges from 14 to 20 inches (35.6 to 50.8 cm), depending on the model and intended use.
For our most popular 32-gallon commercial round can, the internal diameter is precisely 18 inches (45.7 cm). This measurement is taken at the widest point of the circular opening, where the lid or liner ring sits. The 18-inch diameter ensures compatibility with standard 32-gallon trash bags and provides an optimal balance between waste capacity and ease of access for users.
However, we offer customized options to meet diverse client needs. For smaller applications, such as under-counter units, the internal diameter can be as narrow as 14 inches. For larger, high-volume environments like event venues, we produce models with a 20-inch internal diameter to accommodate bulky waste and larger liners.
It’s important to note that the internal diameter differs slightly from the external rim diameter, as the walls of the can are typically 0.08 to 0.12 inches thick. To ensure a perfect fit for liner bags or custom lids, we always recommend measuring the internal opening at its widest point using a calibrated caliper or a tape measure placed at the center.
Our factory uses precision tooling during production to maintain tight tolerances within ±0.05 inches for all commercial round cans. This consistency guarantees that clients receive uniform openings, reducing waste management headaches. If you need a specific diameter outside our standard range, please contact our engineering team for a quick feasibility assessment.
In summary, the internal diameter of our commercial round can’s opening is engineered for practicality and durability, generally spanning 14–20 inches, with 18 inches being the industry-preferred standard. For exact dimensions on a specific model, always refer to our technical datasheet or request a sample.
