WEIGHT PLATE CONSTRUCTION
How many times have you heard the phrase, “weight is weight,” or “a plate is a plate,” or
“how much per pound”? All iron weight plates
are “sand casted”. Like footprints at the beach,
an impression in the shape of the weight plate is made in damp sand, and molten iron is poured into the cavity. A number of factors influence
the quality of the finished product: the fineness
of the sand; the cleaning of the sand between castings; the moisture control of the sand, the grade and purity of the iron; the temperature control of the molten iron; the length of time the casting is left in the mold (the longer, the better). Most manufacturers claim accuracy within +/- 2% of declared weight. For a 45 pound weight plate, this means a range of 44.1 to 45.9 pounds. This
is acceptable for non-calibrated Olympic plates. There is no place in a first class weight room for plates that don’t weigh what they say or that don’t fit snugly on the bar. When you have quality Olympic plates on your exercise floor, you will see, feel, and appreciate the difference.
