ground types
About any type can damage Steel-types, but its weaknesses are Fire, Ground, and Fighting-types. It's not recommended to fight them with Steel, Grass, Ice, Flying, Rock, Fairy, Psychic, Bug, and Dragon-types, for they are resistant to those types. It is completely immune to Poison-types.
