Powder Coating for Steel Substrate Applications

Protecting Steel against the environment is of vital importance as corrosion may affect the structural properties. The prefered method of pretreating Steel prior to painting is to Sandblast to SA2.5 (near white metal) and utilizing an epoxy based primer either with or without zinc as a sacrificial element. An alternative is to utilize an Iron or Zinc Phosphate pretreatment. A very popular standard for specifying corrosion protection on Structural Steel is ISO 12944. This Standard was developed to assist engineers, architects and corrosion experts in specifying the proper paint system for corrosive environments.
