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.

459 kg set of metric calibrated plates

These plates are a great value in calibrated plates. My shipping experience was excellent with the shipping fast and deliver easy. Came on a 5 ton with a power tailgate. The driver had an electric pallet jack and delivered the whole skid of plates to my garage door. The plates were all in great shape with the packaging all intact. There was a small issue with the 2.5 kg plates missing but this was dealt with very quickly by the excellent customer service at B of S. As mentioned in other reviews the lip on these plates make them easier to handle than other calibrated plates and the finish is nice and not slippery. Overall I could not be more pleased.

55 LB Calibrated Plates

I bought these plates due to the lack of space on my Safety Squat bar. These plates have worked perfectly and given me the room I need to keep getting the gains I was working for. Worth the price. The only negative was the package. The plates got scratched during shipping.
