ABUS retains in-house control of all materials used to produce our locks throughout the entire production process.

We personally source and select all materials and determine what works best per application. We source the highest grades of steel to reach the best possible security across all price and product levels and materials are inspected and subjected to the toughest quality control measures.

ABUS employs sophisticated hardening processes for consistent steel quality and improved security. Our special hardening processes keep the steel softer on the inside and harder on the outside for extreme resistance to cutting and twisting at the same time.
