About
The character "钣", denoting a metal plate, derives from its traditional form "鈑" which structurally combines the metal radical "金" with the component "反" functioning phonetically. In the simplified form, the radical is altered to "钅" while "反" remains unchanged. Etymologically, the character has consistently represented flat, worked metal, with its application narrowing to specify manufactured sheet metal in industrial and technical domains, reflecting its entrenched association with metallurgy.
