Though the Ironman Quick-Lock dumbbells have a look that is quite old-school, they are constructed with the best quality materials. These are not the dumbbells from the year 1985. Ironmaster believes in quality, and all their products are a complete reflection of that belief.

Every single iron weight plate has been cut to a precision not just to look good but to perform equally well. Each plate has grooves that are designed to ensure the plates fit seamlessly together when they are added to the dumbbell’s end. This is why there is no rattling noise or shaking when you secure the locking screw.

The dumbbells do not have any plastic parts or fragile parts. They are made of metal, be it the weight plates, locking screws and axle. The plate fitment is well-designed. The handles and locking screws are made of top commercial quality steel. The metal used builds up the durability of these dumbbells.
