To shield any electronic item metal sheet is required to be covered the item.

When electromagnetic  wave strikes the sheet, its the electric and magnetic fields are absorbed by free electrons in the plate and weakens it as it progress through the sheet. This way sheet can give good shadow region for EM waves not the ground wire.
