Harden Architectural Security

Maximum Security Doors


DOS certified steel systems are tested to withstand 60 minutes of simulated ”mob” attack and rifle-level ballistic rounds. Door leaves are opaque and include three manually thrown locks that engage into a structural steel frame for very high levels of resistance to forced-entry attack. Options consist of various single or double leaf configurations and a 180 minute UL fire rating.

Design Overview

ANTI-TERRORISM LEVEL SECURITY where conformance to U.S. Department of State forced-entry / ballistic resistant threat levels is required

ARCHITECTURAL APPEAL the reinforced steel frame provides the look of a commercial hollow metal door and complements modern architectural design

DESIGN FLEXIBILITY numerous cladding and trim options offer the ability to complement other building materials

EASE OF OPERATION the use of high quality hinges results in very low pull forces

DURABILITY structural steel materials and high-quality hardware provide extreme durability and low maintenance throughout the life cycle

Harden Steel Security FEBR Doors offer DOS certified protection against mob-level forced-entry attacks and rifle-level ballistic threats in a structural steel, pre-hung assembly engineered for long term durability. With numerous configurations, materials and hardware options available, these doors are highly adaptable to a wide spectrum of uses and architectural designs. Maximum and High Security Doors safeguard mission critical buildings, guard houses, control rooms, executive offices and anywhere the highest level of protection, aesthetics, and durability are important considerations. An optional 3-hour fire rating on certain products allows the doors to be used in rated fire walls and fire barriers without sacrificing any forced entry or ballistic protection.
