Because steel is certainly heavier than plastic and wood.
Secondly, let's look at the product characteristics of the caster: The biggest feature of the caster made of steel is that it is strong, very strong, and very smooth. There is also a caster made of plastic. The caster is made of professional plastic and has a simple structure, but the balance is particularly good and the scope of use is particularly wide.
