Yes, iron plates are generally heavier than plates made of other materials due to the high density of iron.
Boats covered in iron are commonly referred to as ironclads.
Rubber plates are quieter, protect floors better, and are easier to grip. Iron plates are more durable and provide a more traditional feel.
