Moving Parts

Where articles require free movement of parts, e.g. drop handles, hinges, shackles, shafts or spindles:

  • A radial clearance should be applied to the part to allow for the galvanized coating thickness. Recommended minimum radial clearances are shown in Table 5.
  • Parts need to be disassembled and galvanized separately.


Table 5:

Recommended minimum radial clearance before galvanizing

Shaft or spindle size (mm)Minimum radial clearance (mm)
< Ø10 1.0
≥ Ø10 to ≤ Ø30 2.0
> Ø30 2.5

Note: Some fettling may be required after galvanizing to enable parts to be free moving.
