Heavy Metal Barbell (HMB) was founded by Greg Olson in 2014 in response to a market need for high-quality OEM Olympic barbell manufacturing. Prior to establishing HMB, Greg co-founded PowerBlock, known for its innovative adjustable dumbbells. As a family-owned business, HMB prides itself on being a 100% USA-made OEM barbell manufacturer. We offer comprehensive services, including design, drawing, prototyping, manufacturing, and sourcing. Trusted by leading names in the fitness industry, Heavy Metal Barbell stands as a symbol of excellence and reliability.
With the industry shifting to custom branded equipment we know how important customization is. Our services include branded endcaps and custom end caps for your customer.
Customize your bar with text or logos. Stand out from your competition with the capability to fully customize your barbell.
We understand that knurling is a personal preference, so we offer a range of options to suit every need, from passive to aggressive knurling. To ensure a clean and consistent pattern with sharp, precise lines, we frequently update our knurling tools.
All our bushing bars feature a custom stepped, self-lubricating bushing that ensures some of the industry’s tightest tolerances. These oil-impregnated bushings provide long-lasting lubrication for superior spin. In fact, our bars tend to spin better with extended use.
We utilize precision ING needle bearings, originally designed for high-speed conveyor belts. Our suppliers think we’re crazy, but the exceptional quality of these bearings ensures longevity and sets our bars apart from others on the market. Each bar is equipped with ten bearings to deliver premium performance.
All of our bars, except for the aluminum training bar, are made from TGP steel. While many companies overlook this due to the cost, using TGP steel ensures superior spin and a premium finish for our barbells.
All of our bars are constructed with our precision-machined dual snap ring design. This superior design allows for easy maintenance, ensuring the bar can be used for a lifetime.
All of our barbell components are sourced and made from 100% US steel. Unlike competitors who import ends and other components, we manufacture barbells that are entirely made in the USA.
Our zinc bars undergo a meticulous process, being racked and dipped through multiple electroplating cleaning baths before plating. The zinc coating provides a bright finish and is ideal for commercial use due to its oxidation resistance and durability. As one of the thinnest coatings, zinc preserves the knurl’s crispness.
Cerakote is one of the strongest and thinnest ceramic coatings available. Our Cerakote bars undergo thorough cleaning and media blasting before coating to ensure premium adhesion. In corrosion salt spray testing, Cerakote lasts 70 times longer than chrome and stainless steel. Proven in the gun industry for years, Cerakote has stood the test of time. We use the H-Series, which is baked after coating.
