Compared with 3CM countertops, 2CM quartz countertops use less materials, so they are relatively low in cost. For home or commercial projects with limited budgets, 2CM countertops are a more cost-effective choice.

Based on the above mechanical analysis, in general, the maximum unsupported span of a 3 cm thick quartz countertop without additional support is recommended not to exceed 24-36 inches (60-90 cm).
