Why this matters
Outdoor exposure is not one standard condition. A sheltered cabinet, a horizontal padlock under direct rain and a coastal gate can present very different risks.
What to confirm
Determine where water comes from and where it can remain. Consider condensation, freeze-thaw cycles, salt, dust, temperature, mounting direction and whether drainage or a protective cover is available.
A practical working method
Use the worst representative condition for a sample installation and follow current manufacturer guidance for operation and maintenance. Appearance alone cannot demonstrate corrosion resistance or suitability.
Records, acceptance and handover
Document the selected model, installation orientation, environmental assumptions and inspection routine. Protection provided by the door, hasp, cover and drainage design is part of the overall solution.
Evidence and scope
This article is intended for preliminary product and project discussions. Product functions, performance, certification, compatibility and availability must be checked against current documentation for the selected model and the actual project requirements. Application examples are not claims of completed customer projects.
