If you're steaming with a plate, dish, or bamboo steamer, you need a steamer rack as well because the boiling water should never be high enough to touch the bottom of the plate nor should the water be able to boil over onto the plate. The food is supposed to be cooked by the steam and not from direct heat.
Great to use for steaming veggies. Must have in your list of cooking tools.
Removable legs allow it to fold flat for storage.
The plate is made steel. The legs are also made of steel.
