Purpose: This is one of the largest and most formidable standard safes in WELKO's Premium lineup, explicitly featuring a traditional physical key lock. It's designed for the most demanding security requirements for vast quantities of high-value assets, critical documents, and large sums of cash, typically in commercial banks, national archives, major corporations, or for ultra-high-net-worth individuals/families. It emphasizes robust mechanical security and immense storage.
Characteristics: Standing over a meter tall, this safe offers monumental internal capacity. Its key-lock system provides extreme reliability, unaffected by power, batteries, or electronic failures, making it a truly long-term, low-maintenance security solution.
Key Features (based on search results for WELKO US1080 models, focusing on key-lock variants):
External Dimensions (H x W x D): H 1080 x W 600 x D 600 mm. This is a very tall and wide safe, making it a commanding presence and offering exceptional storage.
Internal Dimensions (H x W x D): Consistent listings show internal dimensions of H 700-800 x W 450-510 x D 350-450 mm. A common figure is H 800 x W 450 x D 450 mm, providing vast usable space for multiple large binders, extensive document archives, and various high-value items.
Weight: Approximately 500 - 850 kg. Several sources specifically for the US1080 key-lock (or "khóa cơ") variant cite a weight of 500 kg ± 10 kg, while some electronic models go up to 850kg. For the "clé" version, 500 kg is a confirmed figure, indicating extreme robustness.
Locking Mechanism: High-security physical key lock(s) and/or Mechanical Combination Lock ("khóa cơ"). While you specifically asked for "clé" (key), many large WELKO safes, especially those designated "khóa cơ" (mechanical lock), often incorporate both a high-security key lock and a mechanical dial combination lock. This provides redundancy and enhanced security. The keys are typically complex, multi-bitted, or dimple keys, designed to be highly pick-resistant. There are no electronic components in this "clé" or "khóa cơ" variant.
Fire Resistance: Confirmed as Fireproof (ignifuge) for premium WELKO safes of this caliber. It is typically rated to withstand extreme temperatures of 1000 - 1200°C for 2 hours, ensuring that paper documents, digital media, and other heat-sensitive contents remain protected during severe and prolonged fires.
Burglary Resistance & Construction:
Ultra-Heavy Gauge Steel Construction: The body is made from thick steel plates (e.g., "thép dày 10mm" - 10mm thick steel for the body, and "thép cánh dày 14mm" - 14mm thick steel for the door), with the door often being solid cast steel ("thép đúc nguyên khối") and hydraulically pressed.
Advanced Composite Barrier: The substantial space between the inner and outer steel walls is filled with a dense, proprietary fire-resistant and anti-penetration composite material, making it extremely difficult to drill, cut, or impact.
Massive Multi-Point Locking Bolts: Features a large number of very robust, large-diameter, solid steel locking bolts (some sources say "16 chốt tròn INOX to bản lớn" - 16 large round INOX bolts) that engage deep into the safe's reinforced frame from multiple sides, providing formidable resistance against prying and cutting attacks.
Anti-Pry Design: The door jambs often feature a "hèm cửa dạng tam cấp" (step-like door jamb) or similar anti-pry designs, further enhancing security.
Re-locking Devices: Mechanical re-locking devices are often integrated, which will automatically secure the safe if the lock mechanism is attacked.
Internal Configuration: Includes multiple heavy-duty, adjustable shelves for highly flexible and extensive storage. It also features a sturdy, internal lockable drawer for an extra layer of security for smaller, highly confidential items.
Durable Finish: High-quality, aesthetic, and durable paint finish (e.g., "sơn tĩnh điện chống trầy xước" - electrostatic scratch-resistant paint) that is resistant to corrosion and wear, maintaining the safe's premium appearance.
Mobility & Anchoring: Some listings mention "có bánh xe dễ cho việc lắp đặt và có thể tháo rời" (has wheels for easy installation and can be removed), which is crucial for a safe of this weight. Despite wheels, it will also have pre-drilled holes for securely bolting it to the floor for maximum security against unauthorized removal.
Advantages of Key/Mechanical Lock:
Extreme Reliability: No reliance on batteries, electrical power, or sensitive electronic circuits. Immune to power outages, EMPs, or electronic malfunctions.
Simplicity and Directness: Straightforward to operate once the combination (if applicable) is known and the key is used.
Exceptional Longevity: Mechanical locks are known for their long lifespan and minimal maintenance.
Robust Security: The sheer mechanical integrity of these locks, combined with the safe's construction, offers formidable protection.
Disadvantages of Key/Mechanical Lock:
Key/Combination Management is Critical: The primary challenge is securely managing the physical key(s) or remembering the mechanical combination. Loss, theft, or unauthorized duplication of keys/combinations can compromise security. Losing the key or forgetting the combination typically requires a professional locksmith.
Less Convenient for Multiple Users: Requires physical key transfer or sharing the combination, which can be cumbersome.
No Audit Trail: Does not provide a record of who accessed the safe or when.
No Integrated Alarms: Lacks the electronic alarm features (for impacts, incorrect codes, etc.) common in digital models.
Availability & Price in Vietnam: The WELKO US1080 with a key and/or mechanical combination lock is a flagship premium safe and is available through authorized WELKO distributors and major safe retailers in Vietnam. Its price reflects its immense size, extraordinary weight, and top-tier fire/theft protection. As of May 2025, prices for the WELKO US1080 clé / khóa cơ would typically range from approximately 32,000,000 VND to 62,000,000 VND, with some listings showing higher original prices before discounts.
