Upon its inception, Black Iron Strength launched a series of new products to help strength professionals obtain an edge in training. The goal of Black Iron Strength was to provide the world's best strength equipment, which would be manufactured in the United States with the highest grade materials and detailed craftsmanship. That means the custom dumbbells, barbells, kettlebells etc are all made in the USA with the best materials available. There would be no compromise on design and innovation. Today, Black Iron Strength continues to produce the best products in every free weight category and stands behind all products produced with a solid warranty. No other company in the world can claim that they manufacture higher quality Thick Bars, Solid Steel Dumbbells, Solid Steel Kettlebells, Solid Steel Barbells, and Attachments than Black Iron Strength. We are the first and only company in the world to offer the Germ Buster line of products with CuLEAN antimicrobial copper touch points by CuVerro on our free weight handles to protect users from MRSA and other bacterial infections 24/7. This technology has been approved and registered by the Federal and State Environmental Protection Agencies. Black Iron Strength offers multiple dumbbell handle choices to serve our customers needs. There are nine different sizes of thick bars available. We have selected solid steel as our material of choice to keep the free weights as small as possible, which improves the balance and control for the lifter.
