All weight plates are not for all lifters. The perfect style for you depends on your individual goals.
A typical recreational lifter might not care. And if you’re just starting out or on a budget, any plates are better than no plates.
But if you want to make an informed decision, here’s a look at how REP’s weight plates differ in terms of material, weight tolerance, size, and other features, and how to pick the right style for your home or commercial gym.
The Different Types of Weight Plates
There are several types of weight plates:
Iron plates
Iron plates are just what they sound like: the hard, iron weight plates that make clanking noises and that satisfying, sharp, sliding sound when you load them onto your barbell. Iron plates are those classic, old-school circles. They’re usually silver or black. There are different types of iron plates.
Bumper Plates
Bumpers are rubber-coated plates that can be black but are also frequently multi-colored. These typically have a steel core surrounded by a thick, high-density, rubber coating (not to be confused with the thin coating you may find on irons to protect them from scratches). You can find a variety of fun bumpers of different colors, patterns, and styles.

Fractional/Change Plates
Change Plates and Fractional Plates (also called micro plates) are lightweight plates to add to your barbell for tiny jumps. For bigger, compound lifts like deadlift, the smaller Fractional Plates may not always be useful, but the ability to make a wee jump on upper body lifts -- like bench press, barbell curls, power cleans, or overhead press -- can make a huge difference.

A Look at the Different Kinds of Weight Plates
