1 square foot is about 929 square centimeters and 2CM thick, so the volume of 1 square foot of 2CM thick countertop can be calculated as: Volume = 929 × 2cm = 1858 Then, multiply the volume by the density of the quartz countertop (taking the middle value of 2.35 grams/cubic centimeter), and you can get the weight per square foot: Weight = 1858 × 2.35g/=4366.3g=4.366kg

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.

But in fact, the thickness of 2CM is enough to withstand various loads in daily use. Quartz countertops are an engineering material whose strength depends not only on thickness, but also on the density of quartz particles and the bonding effect of resin.

According to the recommendations of manufacturers and architectural design, a 2 cm thick quartz countertop is usually safe to span between 60 cm and 80 cm (about 24 inches to 32 inches) without support.
