The shape of the grill mesh may seem like a design difference, but it has a direct impact on the grill fit and experience. Round and square mesh, which are commonly found in the market, perform very differently in different scenarios -- round mesh may be more suitable for heat distribution in charcoal grills, while square mesh is more advantageous in built-in grills. A deeper understanding of the differences between the two in terms of adaptability, ease of operation, space utilization, etc. is necessary to match the grilling tool with the needs of the scenario.
