Exceptionally accurate calibrated plates, without the ridiculous price tag.

Powerlifting contests are done using calibrated plates, yet most commercial gyms use generic plates

that are notorious for being inaccurate — sometimes, up to 10% off their claimed weight *GASP!*


And to land the podium in the big leagues, you need your training plates to weigh EXACTLY what they say they are, not plus or minus, well…. anything!

Bells of Steel calibrated plates are certified for accuracy by the Canadian Government

Benefits of Calibrated Plates

    Regular weight plates can be up to +/-10% from the claimed weight, which throws a lil’ bit of a curveball in your plans if you compete in powerlifting. I mean, it’s a sport where literally every pound matters. Off by half a pound on your best deadlift because your inaccurate plates gave you false expectations? It could cost you a podium finish. With our calibrated plates, you’ll know EXACTLY how much you’re lifting in training, so you’ll know your record-breaking attempts are right on the money.
    These calibrated plates don’t quite match IPF specs. I mean, they’re NOT approved by the IPF in the first place, but they do check the key boxes: standardized diameters, correct colour-coding, and guaranteed to be within +/-10 grams of the claimed weight. The thing is, they’re made in pounds instead of kilograms because, well… #freedomunits. But, don’t let that rain on your parade, they still make excellent training plates for powerlifting.
    Calibrated plates are the powerlifting behemoth’s dream come true. The heaviest of the set (55lb) is only 28.5mm thick, which is barely over 1-inch. And when compared to our slim Machined Plates, our calibrated plates are 20% thinner, making them 30% thinner than the industry standard — talk about thin! Oh and don’t worry… your up-and-coming 1,000lb deadlift will fit on a powerlifting bar without a single issue 😉
    If you’ve ever pulled your 1 rep max with pound plates AND with calibrated plates, you know that the two aren’t quite the same. Calibrated plates are thinner and don’t extend so far on the sleeves of the bar, so there’s less flex in the barbell which makes the pull noticeably harder. Which is maybe something important to test out before you try to hit a personal record on your final pull? It might seem minor but if you train like you compete, you’ll be a step ahead of your competitors. To learn more, check out What Are Calibrated Plates.

Solid, attractive plates.

So I want to come right off the bat and say 1 of my 6 55lb plates seems to have some kind of paint prep problem. The color is different from the other five, and there is some flaking and..bubbling for lack of a better word? They all have various scuffs here and there from shipping, but I'm not precious about that, and it's really the nature of shipping heavy iron plates in boxes. The other plates are all beautiful. They will all touch the ground, and I will ruin the very nice finish on them and be happy to do it. I think expecting total perfection is unreasonable, and I would recommend these to anyone who feels similarly.

Calibrated Metal Plates (lb)

I bought the following metal plates: 4x25 lb, 4x10 lb, 2x5 lb an 2x2.5 lb, to complement the calibrated bumper plate set that I got at the same time. The 25 lb plates are used for everything but come in handy for landmine exercises as the diameter is less than the 25 lb bumpers allowing me a greater range of motion on some exercises. There has been some chipping of the paint on the plates, but that is to be expected. I have been very happy with the plates and recommend them.
