When serious firearm owners demand uncompromising protection, the Steelwater Heavy Duty 16 Long Gun Safe (SW592216) delivers elite-level security, fire protection, and advanced access control in one formidable solution. Built for homeowners, collectors, and small businesses alike, this safe is engineered to protect firearms, valuables, documents, and irreplaceable assets from theft, fire, and environmental damage.

With 12-gauge steel construction, 10 massive solid steel locking bolts, and 60 minutes of fire protection at 1875°F, this safe exceeds industry expectations and even meets California DOJ standards for residential security containers—a benchmark for reliability and compliance. From reinforced bolt-down anchoring to EMP-resistant digital locking technology, every detail of the SW592216 is designed for long-term peace of mind.

Built for Strength, Fire Resistance & Real-World Threats

The Steelwater SW592216 features a composite 4 7⁄8” thick door reinforced with dual layers of fireboard, paired with double-layer fireboard insulation throughout the walls, ceiling, floor, and door jambs. This design creates a heat-resistant chamber capable of protecting contents during intense fire exposure while also sealing out smoke and water with a heat-activated expandable door seal that expands up to 8× its original thickness.

Its gear-driven lock and bolt system delivers superior resistance against prying, drilling, punching, and brute-force attacks. In the event of a lock breach attempt, an internal spring-loaded re-locking bolt automatically secures the safe, preventing unauthorized entry even if the lock is compromised.

Advanced Locking Technology with EMP Protection

Security doesn’t stop at steel. The SW592216 includes an EMP-Proof Chrome Digital Keypad, ensuring reliable access even during power disruptions or electromagnetic events.
