'metalized' originates from the verb 'metalize', which comes from the word 'metal', derived from Latin 'metallum', meaning 'mine, quarry, metal'.

'metalize' evolved from the Latin word 'metallizare', which meant 'to turn into metal', and eventually became the modern English word 'metalize'.

Initially, it meant 'to turn into metal', but over time it evolved into its current meaning of 'coated with metal'.
