Zinc hot dip galvanizing
Introduction This Japanese Industrial Standard has been prepared based on the
first edition of ISO 1459 Metallic coatings-protection against corrosion by hot dip
talvanizing-guiding principles and ISO 1461 Metallic coatings-hot dip go
coatings on fabricated ferrous products-requirements, published in 19 luanized
However, some items not specified in the corresponding International Standards have
been additionally contained herein as Japanese Industrial Standard, and retest"
specified in the corresponding International Standards has been eliminated
The portions with side lines or dotted underlines show the matters not included.

iron and steel products to serve corrosion resistance, excluding hot-dipped zinc-coated
steel sheets, zinc-coated iron wire and zinc-coated steel wire. etc
Note (1) The significant surface means the surface area which forms essential
part in practical use
Remarks: The corresponding International Standards to this Standard are shown
as follows
ISO 1459: 1973 Metallic coatings-protection against corrosion by hot
dip galvanizing-guiding principles
ISO 1461: 197 Metallic coatings-hot dip galvanized coatings on
