Precision Weight Plates, Machined to Perfection.

Weight is weight, right? Your plates should add weight to the bar; that’s their job; it’s not rocket science!

But what if I told you your sloppy, 45lb plates you got for your 16th birthday from the local big box store were lying to you? The process of casting molten hot iron into moulds can be fickle.

Cast plates manufactured without proper quality control protocols can have as much as 4lbs weight variance, meaning you might have 41lbs on one side of the bar and 48lbs on the other side; leaving you prone to injuries from imbalanced bars, or even worse, finding out at your competition that you are 10lbs weaker than you thought, and missing the gold medal!

Our new machined iron plates are cast in a specialty casting factory with over 40 years of experience, then finished on a lathe that shaves of excessive weight from the back of the plate, followed by polishing and machining edges for an even smoother, more aesthetic plate.

The machined plates are a guaranteed tolerance of +/- 1% for 45, 35, and 25 and +/- 3% for 10, 5, 2.5. However, in our strict quality control and inspection, most plates are under that tolerance, and many fall within 10 grams of the claimed weight.

But we don’t stop there; the holes of the plates are cast smaller than the Olympic bar sleeve diameter of 2 inch/50mm and is then drilled out with a guaranteed precision hole fit of 50.5mm +.4mm tolerance, meaning your plates fit snug and erect on your bar.

Finally, the plates are smoothed, and any excess dirt/dust is flamethrowered off before being finished with an ultra-durable hammertone powder coat.

This additional precision work makes for a more expensive (albeit worth it!) weight plate. If you’re looking for excellent quality but a less precise plate, be sure to check out our mighty grip iron plates.

Awesome Plates

I was in the market for some new plates that would have better accuracy to the displayed weight as my old ones were not close. After looking around online I settled on the Bells of Steel Machined 45lbs plates. I wish I could have gotten these when I first started building my gym. I made an order for 6 sets of 45’s and did pick up. The custom set options helped to knock some of the cost down. Attending to pick them up was easy and seem less. Plates were packed well and I don’t believe there was any damage from where they are manufactured to the store. I found the solid grey to not be the best looking but I did buy some oil markers and coloured the letters. There was some marks and blemishes on the plates which seemed to be during manufacturing. The main reason I wanted these plates was due to the claim that their advertised weight is extremely close with not costing competition plate prices. Bells of Steel nailed this out of the park. In weighing all 12 plates they all had a weight of 45.2lbs. On the bar the weights don’t have a lot of play or movement and I have found this makes deadlift a lot quieter even with all the plates on the bar. I am very happy with this purchase and would highly recommend these plates for people building a home gym for general fitness or for people who are looking to compete in weightlifting sports. I will be looking to get some some sets of 25-2.5 lbs plates in the future. Bells of Steel has always been awesome to deal with and in past purchases where I needed to contact them they were extremely helpful and quick to respond.

Awesome quality for price

These plates were well within tolerance and were available for quick pick up in Toronto. I have 10s, 5s, 2.5s I use them in every workout for loadable dumbbells. Well priced, quality plates.
