Scope

This Part of GB/T 19355 provides guidelines and recommendations to the fundamental
principle that is applicable to anti-corrosion sherardizing design of workpieces.
The sherardized coatings’ protection of workpieces depends on the construction
method of sherardized coatings, the design of workpieces and the specific
environment where workpieces are exposed to. Sherardized workpieces can adopt
additional coatings (beyond the range of this Part of GB/T 19355), for example, organic
coatings (wet coatings or powder coatings), which can provide further protection. This
combined coatings that are applied to sherardized workpieces are generally known as
“composite coating system”.
Please refer to ISO 12944-5 and EN 13438 for the basic guideline of this question.
The anti-corrosion maintenance of sherardized steel workpieces is beyond the range
of this Part of GB/T 19355.
Relevant requirements of specific products (for example, sherardized coatings of
fastening pieces or steel pipes) shall be prior to the basic recommendations in this Part.
