Bulletproof Steel Plate - Ballistic-Resistant Armor Plate for Military & Security Applications

Bulletproof steel plate represents a critical protective material engineered to withstand high-velocity projectile impacts in defense, law enforcement, and security infrastructure applications. Manufactured through specialized heat treatment and alloying processes, these ballistic-resistant armor plates deliver exceptional hardness ratings between 500-600 HBW while maintaining structural integrity under extreme threat conditions. Our factory-direct bulletproof steel plate solutions serve military vehicle armoring, personnel protection systems, and critical infrastructure shielding requirements across 47 countries, meeting NIJ Level III, IV and STANAG 4569 ballistic resistance standards.

What is Bulletproof Steel Plate?

Bulletproof steel plate is a high-hardness armor-grade steel alloy specifically designed to defeat ballistic threats through energy absorption and projectile deformation. Composed primarily of carbon steel with manganese, chromium, and molybdenum additions, this material achieves surface hardness levels of 500-600 Brinell while maintaining a ductile core structure that prevents catastrophic brittle failure upon impact.

Bulletproof Steel Plate Technical Specifications

Our ballistic-resistant armor plate conforms to MIL-DTL-46100E and STANAG 4569 Level 2-4 requirements. Chemical composition includes carbon content of 0.28-0.35%, manganese 1.0-1.6%, chromium 0.5-1.2%, with tensile strength exceeding 1,250 MPa minimum. Available thickness ranges from 6mm to 50mm with density of 7.85 g/cm³ at 20°C, supplied in flat plate format up to 3,000mm x 12,000mm dimensions per ASTM A829/A829M standard.

Solid Performance with Minor Documentation Delay
Ordered 5 tons of 12mm bulletproof plate for perimeter security barrier project. Material quality excellent with 535 HBW hardness and full STANAG 4569 Level 2 compliance. Ballistic testing results were comprehensive. Delivery was prompt at 39 days. Mill certificates arrived 3 days after shipment which caused minor customs clearance delay, but supplier expedited corrected documents immediately. Product itself met all specifications perfectly. Good value for Southeast Asian market.

Good Value Armor Steel for Vehicle Protection
Ordered 6 tons of 15mm bulletproof plate for MRAP door panel application. Material met MIL-DTL-46100E specifications with 545 HBW average hardness. Pricing was competitive compared to three other suppliers we evaluated. Delivery took 47 days, slightly longer than quoted 40-45 days. Minor edge roughness on two plates required additional grinding, but overall quality was solid for the price point. Would order again for non-critical timeline projects.
