Reinforced Steel Security Windows Bulletproof Fireproof Storm Protection Coastal

Constructed with military-grade galvanized steel and a multi-layer ballistic composite core, these windows are certified to NIJ IIIA standards, stopping handgun and shotgun rounds. The integrated intumescent coating expands to 50x its thickness during fires, creating a 2-hour fire-rated barrier (ASTM E119). Engineered for Category 5 hurricane-force winds, the reinforced frame and impact-resistant glass withstand 150+ mph winds and debris strikes (FBC-100/DPAS).

Coastal models feature marine-grade stainless steel hardware and corrosion-resistant finishes, passing 1,000-hour salt spray testing (ASTM B117).

All units include a 3-point locking system, thermal break technology for energy efficiency, and customizable options for size, color, and grille patterns. Professionally installed with seamless integration into existing structures, these windows combine maximum security with architectural aesthetics. Backed by a 15-year warranty, they’re ideal for high-security facilities, coastal homes, and disaster-prone regions requiring multi-threat protection.
