ATB Tercio – ultra-secure burglary resistant safe (Grade 5, EN 1143-1, ECB·S)
The ATB Tercio range consists of ultra-secure Grade 5 burglary resistant safes, designed for situations where a very high level of protection is essential. These safes are officially certified by ECB·S according to the European standard EN 1143-1, Grade 5. This certification guarantees that ATB Tercio safes comply with the strictest requirements for burglary resistance, making them suitable for both professional and private use.
Each safe in the Tercio range is built with a multi-walled steel construction, reinforced with armour plates, internal steel structures and a core of UHPC (Ultra High Performance Concrete). The door is equipped with a three-sided locking system using solid steel bolts, while fixed bolts on the hinge side prevent side attacks. A passive relocking system automatically activates in the event of a burglary attempt.
A fire-resistant intumescent seal around the door and frame provides additional protection against heat, smoke and flames.
The ATB Tercio Grade 5 range includes several models, among them the smallest and lightest Grade 5 safe available on the market. In accordance with the standard, each safe is equipped with two EN 1300-certified Class B locks: these may be two key locks, two code locks (mechanical or electronic), or a combination of both.
With their robust construction, dual EN 1300 Class B locks and advanced security systems, the ATB Tercio Grade 5 burglary resistant safes provide a solution for companies, institutions and private users requiring a very high security level. The Tercio range therefore represents a key part of the professional security solutions portfolio.
