Buyers must distinguish between natural marble, sintered stone, and marble veneer. For high-end B2B needs, natural marble (like Carrara or Calacatta) offers unique aesthetics but requires professional sealing to prevent staining. Sintered stone is a popular modern alternative due to its zero porosity, scratch resistance, and high-temperature tolerance. Ensure the table top thickness is at least 15mm to 20mm for structural integrity, and verify that the base is made of 304 stainless steel or powder-coated carbon steel to support the heavy weight.
