Why Humid Environments Are Particularly Damaging to Locks
Swimming pool and bathroom spaces are exposed to prolonged high humidity, where chlorine, temperature fluctuations, and moisture condensation accelerate metal oxidation. The electroplating or spray coating treatments used on standard indoor locker locks will have significantly shortened service life in such environments. When evaluating, buyers should clearly communicate the "operating environment" to the manufacturer rather than relying only on test results for standard indoor conditions, because the performance difference of the same lock in a dry changing room versus a poolside setting can be measured in multiples.
Three Evaluation Aspects for Corrosion-Resistant Material Selection
Base Material Grade
Ask the manufacturer which grade of stainless steel (e.g., 304, 316) or zinc alloy is used, as different grades have vastly different tolerance to chloride ions.
Surface Treatment
Confirm the type of electroplating layer, film thickness, and salt spray test hours. For pool environments, it is recommended to at least require test data under corresponding conditions.
Sealing and Structural Design
Check whether the lock cylinder, buttons, battery cover, and other parts have waterproof gaskets or sealing designs to prevent moisture from seeping into the internal mechanism through gaps.
What Information to Request from the Manufacturer for a Complete Evaluation
When requesting a quote, it is recommended to obtain three items of information at once: base material certification, salt spray test hours and test standard for surface treatment, and the IP rating or waterproof test results for the sealing design. If the manufacturer can only provide vague descriptions such as "stainless steel material," buyers should further request written documentation or consider whether the product is suitable for high-humidity environments. Jin Tay Industries' OEM/ODM process includes prototype verification and testing certification stages, where humid environment conditions can be incorporated into acceptance criteria.
