How are Heavy Duty caster wheels different from ordinary wheels?

They use a 5.5 mm thick cast-iron core (not a thin pressed core), so they don't deform or crack under heavy loads, and the PU tread resists oil and leaves no marks.

How to Choose Caster Wheels for a 1-Tonne Load

For 1-tonne (1,000 kg) work, we recommend the 6-inch model in a set of 4 wheels, rated up to 1,400 kg per set — a safe safety margin so wheels won't deform midway. Include at least 2 brake casters to lock the cart in place.
