The ArmorShield System provides cost-efficient readily available protection against assault and vandalism at vulnerable door openings such as isolated utility buildings, cashier islands, currency exchanges, box offices, etc. ArmorShield is effective against a wide range of small firearms when used with structures similarly rated. Available in standard door sizes and constructed with armor plate welded inside a 16 gage steel door. Armorshield frames are 12 gage steel with welded corners. ArmorShield's low cost and prompt availability encourage use in a wide range of applications, including those where custom doors might be considered cost-prohibitive. Armorshield doors Level 1 through Level 3 (with Steel Stiffened core) can be optionally UL fire rated up to 90 minutes.
