On the one hand – because it is kind to the environment! If it stands filled with burning charcoal on the meadow the grass roots will not be damaged. Stainless steel conducts the heat badly – so it remains cool under the grill, for extended protection, one of the cutting boards can be used as a support.
On the other hand, it is durable! It can not rust, it lasts for decades! And if it should be discarded – pure stainless steel is always recyclable without loss!
Household items made of stainless steel are food safe, free of plasticizers and BPA and dishwasher-safe
Ad your two cents!
