Weatherproof Outdoor Padlocks

It depends on where the padlock will be used.
All padlocks in this category are marine grade and suitable for harsh environments, including saltwater exposure.
However, for typical outdoor use in the UK - such as on gates, sheds, or storage units - many standard hardened steel padlocks perform perfectly well.

Marine grade padlocks use stainless steel shackles, which resist rust but are slightly softer than hardened steel. If maximum strength is more important than corrosion resistance, a standard outdoor padlock may be the better option.

Generally, no.
Stainless steel is less resistant to cutting than hardened steel, meaning marine padlocks trade a small amount of strength for corrosion protection.
If you only need a padlock for moderate outdoor use, a standard hardened steel model with a protective coating will often offer better overall security.

For general outdoor use, choose a standard weatherproof padlock with a hardened steel shackle and corrosion-resistant body, such as the ABUS Eterna 41 or Squire Lion range.
For marine or coastal conditions, select a fully marine-grade padlock made entirely from stainless or non-corrosive materials.
Models like the Shield MC40 (independent test winner for corrosion resistance) and the ABUS 24IB Discus are proven choices for long-term reliability.

Yes.
Most weatherproof padlocks are suitable for gates, sheds, containers, and external enclosures.
If you’re securing a container or heavy-duty gate, choose a CEN-rated weatherproof model with a closed shackle design for added protection against bolt cutters.

Even the best weatherproof padlocks benefit from occasional maintenance.
We recommend applying a light lubricant to the locking mechanism every few months and ensuring the shackle moves freely.
This helps prevent salt and dirt build-up and extends the lock’s lifespan.
