Crossbar locks are tubular steel extendable clamps that secure the container doors. You can attach them to the locking rods or handles of your shipping containers, and these locks have a keyed lock mechanism that keeps the clamp securely fastened.

Weather-Resistant Materials

Since shipping container buildings are always out in the open, they remain exposed to rain, snow, and other harsh weather conditions. A lock that corrodes quickly can be detrimental to the security of your shipping container. Although all locks may eventually deteriorate over time, buying a weatherproof lock that does not degrade rapidly is always better.

Security Rating

If you want to check how secure your padlocks are, you can look for their CEN (Central European Norm) rating. Padlock manufacturers originally introduced this system to measure the security of the locks they sold.
