Why is it called the Ironside? Because it has more steel than anything in its class. The Ironside Series by Superior Safe Company uses the best American-made steel and sophisticated defense systems to provide premium features you would only expect from more expensive safes.

Superior Safe Ironside SI-31

The Ironside’s door is ironclad.

The SI-31’s body is pressure formed from American-made 12-gauge steel which is almost 3 times stronger than 2 mm or 14-gauge steel. Most China-built or lightweight American containers can’t compete with the SI-31’s quality. With 10-gauge steel plate and a multi-layer 7/16″ edge reinforcement, the door is also ruggedly constructed. The Double-Steel Door Casement™ gives the door opening additional strength. The heavier steel used in the body and door gives the SI-31 a superior, pry-resistant steel foundation.

There’s not just quality steel to the Ironside though. The SI-31 has many security features found only on more expensive safes. It uses a door detent system, Superior’s Auto-Relock™ System, a Sargent & Greenleaf® Group II Dial Lock, and a three spoke handle with a slip clutch. These protect the door and lock from any accidental or intentional damage which means they provide complete protection to your belongings. The SI-31 also has four-way active boltworks and a Diamond-Embedded Armor Plate™. This means that the 14 1″ bolts secure to all four sides of the door for total security.

Two layers of fire insulation and a heat-expanding fire seal give the SI-31 a one-hour 1350° fire rating. Inside the SI-31, you’ll find a plush velour interior. A high-capacity gun-rack, and a deluxe door organizer bring its total gun storage to 36. It’s a steel fortress you’ll be proud to own for many years. As with every safe made by Superior, the SI-31 comes with a lifetime warranty covering the material and craftsmanship.
