bullet proof doors

LG37S Hot-rolled steel series

Produced with hot-rolling technology, the 37 Series delivers a bold and solid profile with exceptional structural stability. Its clean, powerful lines make it ideal for expansive floor-to-ceiling windows, public architecture, and industrial-style projects, creating a strong visual presence and architectural impact.

LG50S Cold-bent steel series

Formed through advanced cold-bending techniques, the 50 Series is distinguished by its slim and refined profile, combining strength with lightness. It is best suited for interior partitions, fine window divisions, and minimalist modern spaces, offering both stability and a sense of elegance.

LG65S Thermal-break steel series

With integrated thermal-break technology, the 65 Series combines the inherent strength of steel with superior insulation and soundproofing performance. It is particularly suited for villas, luxury residences, and high-performance commercial spaces, ensuring both comfort and long-term durability.

steel-look thermal-break aluminum alloy

Built on lightweight aluminum alloy with thermal-break design, the 65 Steel-look Series replicates the authentic appearance of steel while offering aluminum’s advantages of corrosion resistance, insulation, and reduced weight. Perfect for modern homes, apartments, and design-focused spaces, it balances performance with distinctive aesthetics.

Engineered for Extreme Threat Mitigation
Bullet proof doors provide unparalleled ballistic and forced-entry resistance for high-risk environments such as government buildings, banks, and data centers. Unlike standard security doors, bullet proof doors undergo rigorous third-party testing against UL 752 standards (Levels 1-8), ensuring protection against firearms ranging from handguns (Level 1) to high-powered rifles (Level 8) .

 These ballistic-resistant steel doors utilize layered armor systems—typically combining hardened steel plates (12–18-gauge), polycarbonate, and bullet-resistant glazing (1–2.25" thick)—to absorb and disperse kinetic energy, minimizing spalling risks .

Technical Specifications & Certifications

• Ballistic Ratings:

• Level 1–3: Stops handgun rounds (e.g., 9mm, .44 Magnum).

• Level 4–8: Resists rifle fire (e.g., 7.62mm NATO, .308 caliber) .

• Forced-Entry Resistance:

• ASTM F3038/DOS SD-STD-01.01 Rev G testing for 5–60-minute attacks using tools (crowbars, battering rams, torches) .

• Fire Ratings:

• Optional UL 10C certification for 90–180-minute fire containment. 

  .

Core Advantages Over Conventional Security Doors

• Superior Structural Integrity: Bullet proof doors feature reinforced frames (16-gauge steel or aluminum) and multi-point locking systems, offering 300% greater forced-entry resistance than standard steel doors .

• Long-Term Cost Efficiency: Powder-coated finishes eliminate repainting; stainless steel hinges require only biannual lubrication, reducing lifetime maintenance costs by 60% .

• Thermal & Acoustic Insulation: Polyurethane cores achieve U-values ≤0.32 and STC 50+ ratings, enhancing energy efficiency and noise reduction in sensitive facilities like laboratories .

Industry Applications

• Financial Institutions: Full-vision ballistic-resistant steel doors with transaction windows protect teller areas against armed robberies .

• Government & Military: FEBR doors (Level 8) with electromagnetic locks secure embassies and data centers against coordinated attacks .

• Healthcare & Education: Half-lite designs with fire ratings compartmentalize flames in hospitals and schools while maintaining visibility .

Customization & Compliance

• Design Flexibility:

• Flush, half-lite, or full-lite configurations; widths up to 1.5m, heights up to 3m (custom sizes available) .

• Anodized/painted finishes in 50+ colors; ADA-compliant hardware options .

• Global Certifications:

• UL 752 (ballistics), ASTM F3038 (forced entry), EN 1063 BR6 (EU), and GB 12955-2008 (China) .

Installation & Maintenance Guidelines

• Professional Installation Required:

• Frame alignment within ±1.5mm tolerance ensures ballistic seals function correctly .

• Routine Maintenance:

• Quarterly inspection of seals/hinges; replace EPDM weather stripping annually.

• Clean surfaces with pH-neutral solutions; avoid abrasives to preserve ballistic integrity
