The tempered glass tabletop is tempered to withstand weight and force, owing to its being treated by controlled thermal and chemical processes to increase its durability and hardness.
Being 8mm thick after considerable processes and due to greater compression, it's capable of withstanding greater force and thus harder and thicker than normal glasses.
Safety is also not a concern for our dining table since the tempered glasses are known for their wide safety margin to the point that normal glasses dim in comparison owing to the former not breaking into sharp splints but rather into small spherical/circular pieces when subject to considerable force/pressure.
Black powder-coated metal legs and glass suckers on four corners metal legs are intensely durable and strong, thus withstanding the strong glass tabletop for our dining table set.
The glass suckers allow the metal legs to hold up to the tempered glass tabletop.
