Urethane Advantages:

Urethane coated dumbbells offer significant advantages over powder coated steel alternatives.  Some of the major benefits of Urethane Coated Dumbbells are:

  • Greater protection of the plates against minor scrapes and bumps from normal day to day use. Urethane is significantly more scratch resistant than powder coated steel.
  • Greater protection of the plates and dumbbells as a whole against accidental drops or any other impacts. Urethane is highly superior to steel when it comes to vibration-and shock-absorption.
  • Greater reduction of noise. The urethane dumbbells virtually eliminate most noise during use and moving the dumbbells in and out it's stack.
  • Complete resistance to rust. The entire part of the weight block that’s covered with urethane simply won’t rust. Whereas, if the powder coating on the steel plates is scratched or chipped, the exposed steel will rust easily.
