4 Sustainability Excerpt belw frm EPA Resurce Cnservatin website: Sustainable materials management (SMM) is a systemic apprach t using and reusing materials mre prductively ver their entire lifecycles. It represents a change in hw ur sciety thinks abut the use f natural resurces and envirnmental prtectin. By examining hw materials are used thrughut their lifecycle, an SMM apprach seeks t: Use materials in the mst prductive way with an emphasis n using less; Reduce txic chemicals and envirnmental impacts thrughut the material life cycle; Assure we have sufficient resurces t meet tday s needs and thse f the future. The Case fr a Lifecycle Apprach t Materials Management Hw ur sciety uses materials is fundamental t ur ecnmic and envirnmental future. Glbal cmpetitin fr finite resurces will intensify as wrld ppulatin and ecnmies grw. Mre prductive and less impactful use f materials helps ur sciety remain ecnmically cmpetitive, cntributes t ur prsperity and prtects the envirnment in a resurce-cnstrained future. 4

5 Galfan and Sustainability Galfan truly epitmizes the gals f SMM Use materials in the mst prductive way with an emphasis n using less and Assure we have sufficient resurces t meet tday s needs and thse f the future thrugh the fllwing: Zinc cnsumptin reduced by fifty percent with, at least, equal crrsin prtectin Equivalent Catings (based n standard ASTM cating weights) GF20 vs. G z/ft 2 Galfan / 0.40 z/ft 2 standard Galvanized GF30 vs. G z/ft 2 Galfan / 0.60 z/ft 2 standard Galvanized GF45 vs. G z/ft 2 Galfan / 0.90 z/ft 2 standard Galvanized Achieve duble the white rust (sacrificial) prtectin at same z/ft 2 Delayed white rust means even greater red rust (barrier) prtectin at same z/ft 2 Reduced electricity cnsumptin fr Galfan bath (lwer melting pint) GF 820 F average bath temperature GI 870 F average bath temperature 6% higher sustained temperature needed versus Galfan Increased zinc usage = increased charging f zinc pigs = increased electricity cnsumptin f bath t maintain temperature In sme cases, reductin in finished gauge (decreased by cating thickness) can increase lineal ftage / square ftage per tn, thereby reducing cnsumptin f ttal weight needed fr a given prject.
