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.

The SI-17’s body is pressure formed from American-made 12-gauge steel. Most China-built or lightweight American containers can’t compete with the the SI-17’s quality because its steel is almost 3 times stronger than the 2 mm or 14-gauge steel they use. A 10-gauge steel plate with a multi-layer 7/16″ edge reinforcement make the door as ruggedly constructed as the body. Superior’s Double-Steel Door Casement™ also strengthens the door opening. The heavier steel used in the body and door gives the SI-17 a superior, pry-resistant steel foundation.

Superior Safe Ironside SI-17

Superior’s Auto-Relock™ System is just one of the many door defense systems on the Ironside.

There’s not just quality steel to the Ironside though. The SI-17 has many security features found only on more expensive safes. It uses a Sargent & Greenleaf® Group II Dial Lock, Superior’s Auto-Relock™ System, a three spoke handle with a slip clutch, and a door detent system. These protect the door and lock from any accidental or intentional damage. So your belongings are completely protected. The SI-17’s four-way active boltworks and Diamond-Embedded Armor Plate™ mean that the 12 1″ bolts secure to all four sides of the door for total security.

Inside the SI-17, you’ll find a plush velour interior. A deluxe door organizer and high-capacity gun-rack bring its total gun storage to 28. Two layers of fire insulation and a heat-expanding fire seal give the SI-17 a one-hour 1350° fire rating. It’s a steel fortress you’ll be proud to own for many years. As with every safe made by Superior, the SI-17 comes with a lifetime warranty covering the material and craftsmanship.
