Purchasing dumbbells? There are so many different options on the market for dumbbells, especially hex dumbbells. Dumbbells are one of the most used items in the gym no matter if you are performing heavy weightlifting or just aerobic cardio with light dumbbells. Hex dumbbell sets are typically offered in painted cast iron, rubber or urethane encased. Many people will choose based on aesthetics or price but it is always wise to make an informed decision on what is best for your facility or home. So here we will explore the different dumbbell materials available and the benefits of each.

Cast Iron Hex Dumbbells
The very basic entry level for dumbbells is iron hex dumbbells made from solid cast iron. On the lighter dumbbell sizes, both the handles and heads consist of a solid piece of cast iron and are usually coated with a gray paint or baked on enamel finish. Larger iron hex dumbbells have solid steel handles that can be straight or ergonomically shaped. Either way the steel handles are press fit inside the cast iron heads and secured with industrial strength epoxy glue. These are typically going to be the least expensive dumbbells that won’t break your budget. Iron hex dumbbells tend to be perfect for home use and small personal training studios.

Rubber Hex Dumbbells
Rubber dumbbells, such as rubber hex dumbbells, are also made out of iron but the heads are then coated with thick protective rubber. These are great to help protect your dumbbell racks and gym floors. They also tend to be quieter for those users that like to “bang” their dumbbells together at the end of a chest press or similar exercise. As with most rubber products, they might tend to have that distinct rubber smell but this usually dissipates over time. You see rubber hex dumbbell sets frequently used in light commercial gyms and personal training studios.

Urethane Hex Dumbbells
Urethane dumbbells are considered a top of the line dumbbell and usually cost a bit more thane the iron or rubber hex. For example urethane hex dumbbells have an iron or steel base which is then coated with the polyurethane. Visually they look the same as rubber hex dumbbells but the urethane is overall a better and more durable product. There are several advantages to urethane dumbbells over rubber, one being their higher tear strength. In some gyms you may see small chips of rubber that has broken off dumbbells from constant knocking against racks and equipment. Sometimes you will also see rubber scuff marks left on storage racks. With urethane dumbbells you don’t see this happen often because it is a highly impact resistant coating. This material can take a beating. It also does not smell like some rubber products can. If there is any downside to urethane it would usually be the cost as these are more expensive than iron or rubber options. But there are many reasons to make the investment and upgrade to urethane. It will be a product that lasts longer and you won’t look to replace them for a very long time.

Dumbbell Functionality
When it comes to dumbbells, you still are going to be able to produce the same movement and exercise no matter if the heads are just iron or coated with rubber or urethane. It is not going to have a direct effect on your actual workout. Ask yourself what is important for your location. Are you just starting out and looking to make sure you purchase dumbbells for your gym? Then maybe iron is the choice for you. Think about who might be using them and if they are the kind of person to toss equipment around your gym. If you have cast iron hex dumbbells, you run the risk of them damaging your dumbbell racks and flooring so you might want to go with a coated product like rubber instead. Or do you have a little extra money to spend and want to invest in a higher quality product that will last longer? Then upgrading to a urethane dumbbell is the way to go.
