It's unanimous to change typing from Steel to Ground secondary typing.
I say give it some stinky poison moves since it is garbage, also bulldoze and stuff a movepool similar to garbador.
This would be a great starting point, and since you seem to be the bulky utility you'll need some sort of boost move, I'd recommend
Acid Armor or
Bulk Up if even necessary. You need Poison Jab and Iron Head on him. You COULD have Power-up punch or some move like that, as there aren't as many physical viable poison or ground moves to suit this smelly hulk.
