no.

snowflake iron sheet is galvanized steel sheet, and it's better not to use galvanized steel sheet when it is used as tableware, that is, catering supplies, because excessive zinc is also harmful to people.

snowflake iron sheet is also called galvanized iron sheet. It is a kind of metal plated plate, which is galvanized on the surface of low-carbon steel sheet, so it is galvanized plate, commonly known as tin sheet, which is divided into hot plating and electroplating, and is named after its surface pattern resembles snowflakes. These snowflakes, also known as zinc flowers, are produced in the process of zinc plating, and their distribution and shape can generally be controlled. Under normal circumstances, surface zinc plating is not toxic to human body. If it is made into a container to hold water, it is no problem that a large number of zinc ions will not precipitate in a short time. If stored at high temperature for a long time, the water contains a lot of zinc ions, and the human body will be poisoned if it ingests a lot of zinc. However, this probability is quite small. In addition, whether the galvanized iron sheet is toxic or not is also related to the galvanizing process. If the cold plating water is not cleaned and there are toxic substances, cyanide is generally used in the galvanizing industry.
