GERDA HSS 531Z Padlock Disk Mechanism Class 4 PN-EN 12320 Nickel Satin

Product Overview

The GERDA HSS 531Z padlock is a certified security padlock featuring the Hard&Soft System (HSS) technology, designed for high-risk environments such as warehouses, gates, and secured spaces. It meets class 4 certification, with standards in accordance to PN-EN 12320:2013-04 and has been tested by both the Institute of Precision Mechanics and the Central Forensic Laboratory of the Polish Police. The body combines hard and soft materials for enhanced resistance to mechanical attack, and the shackle is made from surface-hardened alloy steel.

Its disk-style cylinder mechanism distinguishes this SKU from generic padlocks, providing proven resistance against picking, cutting, or forced opening. This high mechanical security minimizes the risk of unauthorized access for facility managers, industrial sites, and logistics companies seeking compliance with demanding protection standards. GERDA HSS 531Z is especially suited for bulk procurement in professional storage, property management, and critical infrastructure security projects.
