GERDA HSS 631Z Padlock Class 4 PN-EN 12320 Certified Hardened Steel Nickel Satin

Product Overview

The GERDA HSS 631Z certified padlock is designed for securing storage areas, warehouse gates, bars, and similar access points in professional and industrial environments. Its construction features patented Hard&Soft System technology combining hard and soft materials, with a hardened alloy steel shackle and a disc cylinder mechanism resistant to cutting and manipulation. The padlock holds a class 4 security rating, certified under PN-EN 12320:2013-04 and tested by the Institute of Precision Mechanics and Central Forensic Laboratory of the Police.

What distinguishes the HSS 631Z from generic padlocks is its certified durability against mechanical attacks, including twisting, breaking, drilling, and lockpicking, supported by class 4 security and class 3 corrosion resistance. This eliminates key procurement risks for facilities requiring robust, audit-ready physical security standards. It is particularly suited for facility managers, logistics companies, and industrial buyers needing guaranteed protection for high-value storage, perimeter gates, or environments with strict compliance requirements.
