I had luck when I worked out at home that my dad works in a factory that has compartment for plasma cutting. He got basically for free 7.5 kg, 5 kg, 2.5 kg and 1.5 kg plates. Notice the weird weight. It was because dimensions I said to him didn't exactly correlate to estimated weight. Probably the density of steel was little lower/higher than the one I used in calculations. Each mm shaved off loses weight and each mm added adds a lot to plate.
