Overview

What This Material Is For

Ballistic steel plate is designed to stop high-velocity projectiles and resist penetration under impact, making it essential for military, law enforcement, and high-security applications. Jialu Metal supplies NIJ Level IIIA, III, and IV plates alongside Ar500 and Ar600 wear-resistant grades, all available in thicknesses from 2 to 10mm and widths up to 2500mm. A single order can include mixed grades and sizes, so a project requiring NIJ Level IIIA for vehicle armor and Ar600 for ballistic face shields does not need to be split across multiple suppliers or shipments. The plate is available in standard lengths of 8000, 10000, and 12000mm, or customized to exact dimensions.

Application scenarios

Where It Is Used

  • Armored vehicle and tactical vehicle body panels requiring NIJ Level IIIA or III protection
  • Ballistic shields and personal body armor components using NIJ Level IV or Ar600 for high-impact resistance
  • Secure room and vault construction with Ar500 or Ar600 plates for both ballistic and wear resistance
  • Military and law enforcement equipment where both ballistic and abrasion resistance are required
  • High-security transport containers and mobile command units using mixed-grade plates for layered protection
Buyer profile

Who It Is For

  • Military and defense contractors sourcing armor for vehicles, shelters and personal protection
  • Law enforcement agencies procuring ballistic shields and protective barriers
  • Security firms building secure rooms, vaults and mobile response units
  • Industrial clients needing wear-resistant plates with ballistic capability for high-risk environments
  • Equipment manufacturers integrating armor into tactical gear and mobile platforms
Sourcing pain points

Problems It Solves

  • Splitting armor procurement across multiple mills for different grades, which increases inspection and shipping complexity
  • Delays caused by mismatched plate dimensions when one supplier cannot meet custom size requirements
  • Inconsistent quality or certification when sourcing from unverified suppliers in high-risk applications
  • Lack of availability for mixed-grade orders where one project needs both NIJ and wear-resistant plates
  • Uncertainty in delivery timelines when suppliers cannot confirm stock of specific thicknesses or standards

Material options

Materials

  • High-carbon alloy steel for NIJ Level IIIA, III and IV ballistic performance
  • Hardened alloy steel with 500–600 Brinell hardness for Ar500 and Ar600 wear resistance
  • Steel with balanced tensile strength and ductility to absorb impact without shattering
  • Material suitable for welding, machining and surface coating where required
  • Consistent microstructure across batches to ensure predictable ballistic behavior
How it is made

Manufacturing Route

01Raw material inspection and chemical composition verification before rolling
02Hot rolling to achieve required thickness and flatness
03Heat treatment to achieve target hardness (e.g., 500–600 HB for Ar500/Ar600)
04Cold finishing or leveling for dimensional accuracy and surface quality
05Cutting to specified length and edge preparation as required
06Marking with grade, batch number, and standard reference
Testing and release

Quality Control

  • Chemical composition and mechanical properties tested against NIJ and ASTM standards
  • In-house CNAS-certified laboratory conducts routine testing including hardness and tensile strength
  • Third-party inspection available on request, bookable at order stage
  • Mill certificates issued per purchase order, including test results and compliance statement
  • Batch traceability maintained from raw material to final shipment
What can be changed

Customisation Options

  • Thickness, width, and length specified per project requirement
  • Edge preparation (e.g., beveled, square) available upon request
  • OEM service accepted for branding, marking, and packaging
  • Packing and labeling arranged to meet destination port and inspection requirements
  • Custom sizes and tolerances supported without minimum order quantity
Honest comparison

How It Compares With The Alternatives

Low-carbon steel plateLow-carbon steel is cheaper but lacks the hardness and impact resistance needed for ballistic or wear applications; it deforms easily under high-velocity impact
Ceramic or composite armorCeramic offers lighter weight and higher protection per unit, but steel is more durable in repeated impact and extreme environments, and easier to weld and fabricate
Standard structural steelStructural steel lacks the hardness and ballistic performance of Ar500/Ar600 and NIJ grades; it cannot stop high-velocity rounds or resist abrasion in high-wear zones
How to specify it

Buying Guide

  • Start with the required NIJ level or wear resistance grade (Ar500/Ar600) based on threat environment
  • Specify exact thickness, width, and length in the enquiry to avoid delays in quoting
  • For welded assemblies, confirm whether the plate is suitable for the intended welding process
  • Request third-party inspection at order stage to align with project schedule and compliance needs
  • Include edge preparation and marking requirements early to avoid rework
