Zircon Series

"Outstanding strength and security – exceptional in the marketplace"

For those applications where maximum security is needed.  Suitable for military use, freight containers and trucks, transport applications, heavy steel doors and shutters.


This innovative design provides a padlock body and shackle manufactured out of unique composite steel which undergoes a multi-level process to induce hardening.This includes carbon-nitrogen saturation, quench hardening and tempering resulting in a physically powerful material resistance to cutting, drilling, smashing and extraction. The shackle is dead-bolted with stainless steel balls and a special hardened security case protects the locking cylinder.  The Zircon range is highly resistive to corrosion and can be used in severe weather conditions.

Built with a disc-based locking cylinder technology, there is the option of keyed alike – where one key can fit various padlocks within the range. An innovative master key system with additional levels of sub-access – giving greater control and flexibility when tailoring your application.  See the key feature for design for further information.




The HSS padlocks are certified to meet the requirements of security grade 5 and grade 6 for the standard EN12320 and grade 3 corrosion resistance for the standard EN12320.
