<p>These custom round head dumbbells are manufactured from high-quality cast iron with a durable polyurethane (PU) coating, designed for heavy-duty commercial gym use. Unlike traditional hex dumbbells, the round head design offers a classic aesthetic and allows for multiple grip positions including pinch grip and head gripping for specialized exercises. The PU coating provides exceptional floor protection, noise dampening, and resistance to chipping, cracking, and wear.</p>
