2026-08-10
Compiled by JIALI Industrial (164.hk) — a Hong Kong fastener supplier specialising in screws, bolts, nuts and selection know-how.
Why rust
Carbon steel rusts in humid and salt-spray environments; weak coating or scratches are common causes.
Anti-rust choices
Outdoor/coastal: stainless (304 / 316) or Dacromet / hot-dip galvanizing; dry indoor: zinc plating is enough.
Advice
Inspect critical joints regularly; replace rusted parts and raise corrosion protection where needed.
