Datasheet 4a: Specifying Hot Dip Galvanized Steel

For the vast majority of applications, hot dip galvanizing can be simply specified using the following reference: Hot dip galvanized to BS EN ISO 1461 : 2009 by a member of Galvanizers Association.

HDG Datasheet 4a - Specifying Hot Dip Galvanized Steel

This standard contains coating thickness requirements as shown in Table 1 which will typically be sufficient to achieve an acceptably long coating life.

  • Minimum coating thicknesses achieved by hot dip galvanizing to BS EN ISO 1461 (not centrifuged)
  • Nominal coating thicknesses on samples that are grit blasted prior to hot dip galvanizing
  • Thicker Coatings by Surface Roughening
  • Use of a Reactive Steel
