Indelible marking by laser is commonly specified in mining related applications. The use of stainless steel ensures a corrosion resistant surface that will ensure longevity. The anodised aluminium option is lighter weight and easier to drill whilst retaining high definition clarity. One recent project involved producing identification plates for an array of storage tanks located at an iron ore processing facility. The nameplates needed to comply with the mining specifications requiring deep etched marking on stainless steel to ensure the text would stay visible in the harsh environment.
