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.
