Urethane coating is highly impact resistant and twice as durable as rubber coating. Painted surfaces may chip and rust, rubber can peel off or crack over time. Urethane does not have any specific smell, is resistant to heat, UV rays and even natural wear and tear. Evolve urethane weight plates are extremely durable and do not degrade, so they will keep their perfect appearance even after years of intensive use. These weight plates are a perfect investment for both home and gym users, because they will be cheaper long term and will keep intact longer, than rubber or steel weight plates. These weights will maintain a bold solid color for the lifetime. Urethane coating also protects floor from scratches, damages and absorbs sound during workouts.
