Cast Iron Weight Plates

The type of weight plates you use is largely about preference. One person might opt for tri-grip plates as they’re easier to carry while another might prefer the feel of metal weight plates. That said, there are some benefits to cast iron plates that are worth noting.

The primary one is that you’re much more likely to find both 1-inch and 2-inch hole sizes in cast iron plates. This is great if you have a set of spinlock dumbbells, where you load each plate individually onto the bar, as these usually take 1-inch weight plates, but be sure to check that this is the case for your bar.

2-inch hole sizing is standard for Olympic plates — think the ones you load onto a standard barbell. You can also find cast iron plates in this specification.

Cast iron plates were very much the norm in the 20th century, and although the trend has shifted towards rubber-coated options nowadays there’s still a place for metal weight plates.

The key selling point is the nostalgia factor. When you picture a West Coast gym or Arnold himself lifting heavy, then no doubt the image in your mind includes some iron weight plates. For some people, creating that same aesthetic in their gym is non-negotiable.

Iron weight plates also have a satisfying rattle to them. Whether it’s the clash you hear when loading the plates onto a bar or re-racking it after a heavy lift, there’s something undeniably satisfying to the presence they bring to a gym.

All of the weights we sell, from dumbbells to weight plates, have a maximum tolerance of +/-3%. This means that, if you purchase a 20kg weight plate, we guarantee that it will weigh within 3% of 20kg.

Absolutely. Bring some iron to your compound lifts with our 2-inch cast iron weight plates.

You can, but we don’t recommend it to the same level as we do with rubber-coated plates. While our iron plates are incredibly durable, excessive dropping can chip away at the metal. 

You also need to consider your flooring. Given the hardness of the surface, you should only drop cast iron plates onto appropriate gym flooring if you do choose to drop them.

Store your plates inside in a temperature-controlled environment. In cases where your plates start rusting, wipe some WD-40 oil over them with a dry cloth to restore them to their former glory. 

We don’t recommend it. If your plates pick up moisture then they can start to rust, ruining the aesthetic and compromising how sturdy they are.

Yes, they are. In fact, many lifters will intentionally build a home gym that utilises cast iron weight plates to capture the essence of bodybuilding in its rawest form.
