10. Coffre-fort Premium WELKO US1320 clé (WELKO US1320 Key Lock Premium Safe Box)
Purpose: This is an exceptionally large and extremely heavy-duty safe, designed for the most demanding security needs. It provides monumental storage capacity and the highest levels of fire and theft protection, relying solely on robust mechanical key-locking mechanisms. It is ideal for major commercial entities, banks, government institutions, or very large private estates requiring secure storage for immense quantities of critical documents, large cash reserves, valuable collections, or sensitive equipment.
Characteristics: Standing over 1.3 meters tall, this safe offers unparalleled internal volume in WELKO's standard lineup. Its key-lock operation ensures ultimate mechanical reliability, completely independent of power or electronic components.
Key Features (based on available data for WELKO US1320 models and general WELKO Premium characteristics, with focus on "clé" versions):
External Dimensions (H x W x D): H 1320 x W 600 x D 600 mm. This is a truly massive safe, indicating extreme storage potential.
Internal Dimensions (H x W x D): While exact internal dimensions for the "clé" model are not always explicitly listed, given the external size and standard wall thickness for fire/security, the internal dimensions would be significant. A reasonable estimate is H 1050-1100 x W 450-500 x D 450-500 mm, offering substantial usable space for large volumes of documents, multiple valuable items, or even specialized equipment.
Weight: 600 kg ± 10 kg. Multiple sources consistently cite this weight for the WELKO US1320, regardless of lock type. This is an extremely heavy safe, providing a monumental deterrent to any unauthorized movement.
Locking Mechanism: High-security physical key lock(s). This model would utilize one or more advanced, complex physical key locks (e.g., double-bitted or dimple keys) that are highly pick-resistant. It might also integrate a mechanical combination lock ("khóa cơ") in addition to the key lock for dual security, which is common in high-security large safes. There are no electronic components (keypad, fingerprint reader, digital display, alarms) directly associated with the locking mechanism in this "clé" variant.
Fire Resistance: Confirmed as Fireproof (ignifuge). WELKO US1320 models are rated for excellent fire protection, typically 1000 - 1200°C for 2 hours. This ensures maximum protection for paper documents, digital media, and other heat-sensitive contents during prolonged and intense fire events.
Burglary Resistance & Construction:
Ultra-Heavy Gauge Steel Construction: The body and door are constructed from extremely thick steel plates, often described as "thép tấm bản dày" (thick steel plates) for the body and "thép đúc nguyên khối" (solid cast steel) for the door, possibly ranging from 10mm to 14mm or more in thickness.
Advanced Composite Barrier: The substantial cavity between the inner and outer steel walls is filled with a high-density, proprietary fire-resistant and anti-penetration composite material, making it incredibly resistant to drilling, cutting, and explosive attacks.
Numerous Massive Locking Bolts: Features a large array of very heavy-duty, large-diameter, solid steel locking bolts (likely 16+ large round INOX bolts) that engage deep into the safe's reinforced frame from multiple sides (typically 3 or 4 sides), providing an almost impenetrable seal against prying and forced entry.
Anti-Pry Design: The door and frame are meticulously engineered with tight tolerances and complex anti-pry designs (like stepped door jambs) to prevent leverage points.
Re-locking Devices: Mechanical re-locking devices are almost certainly integrated, which will automatically secure the safe if the lock mechanism or door is attacked.
Internal Configuration: Will include multiple robust, adjustable shelves to allow for highly flexible and extensive storage. It often features a sturdy, internal lockable drawer for enhanced security of smaller, highly confidential items.
Durable Finish: High-quality, aesthetic, and durable paint finish, often electrostatic powder-coated for scratch and corrosion resistance.
Mobility & Anchoring: Given its immense weight, it typically includes heavy-duty wheels for initial positioning (which can be removed) and robust pre-drilled holes at the bottom for securely bolting the safe to the floor, providing paramount security against unauthorized removal.
Advantages of Key Lock:
Absolute Mechanical Reliability: No reliance on batteries, electricity, or electronic circuits; immune to power outages, EMPs, or electronic failures.
Simplicity and Directness: Straightforward to operate once the key is used (and combination, if applicable).
Exceptional Longevity: Mechanical locks are renowned for their long lifespan and minimal need for maintenance.
Robust Security: The pure mechanical integrity of these locks, combined with the safe's formidable construction, offers a very high level of protection against sophisticated physical attacks.
Disadvantages of Key Lock:
Key Management is Paramount: The most significant concern is the secure management of the physical key(s). Loss, theft, or unauthorized duplication of the key(s) directly compromises security. Losing the key or forgetting a mechanical combination (if present) requires professional assistance, which can be costly and time-consuming.
Less Convenient for Multiple Users: Requires physical key transfer or sharing the combination for shared access.
No Audit Trail: Does not record who accessed the safe or when.
No Integrated Electronic Alarms: Typically lacks the electronic alarm features (for impacts, incorrect codes, motion detection) common in digital models.
Availability & Price in Vietnam: The WELKO US1320 with a key lock is a top-tier product and would be available through authorized WELKO distributors and specialized safe retailers in Vietnam. Due to its size and weight, it is likely a special order item. Its price reflects its substantial dimensions, extreme weight, and superior fire/theft protection. As of May 2025, prices for the WELKO US1320 clé are typically found in the range of 50,000,000 VND to 80,000,000 VND or higher, depending on the specific retailer, any additional features or certifications, and specialized delivery/installation requirements.
