A high-quality image of a cast iron standard barbell weight plate weighing 100 pounds (45.4 kilograms). The plate features a rugged textured surface with raised lettering indicating weight in both pounds and kilograms, along with the words “STANDARD BARBELL.” It has a central hole for mounting on a barbell, reinforced by four raised spokes for added durability. The dark gray finish gives it a classic, heavy-duty gym equipment appearance.
