Bulletproof Steel Sheet
Bulletproof Steel Sheet for Armor Doors Walls and Counters
Q+T armor sheet for armor doors walls counters safes and protective equipment
Bulletproof steel sheet, also called ballistic steel plate, is a quenched and tempered armor sheet made by controlled metallurgical processing to hold a hardness of 500-600 HB. Security door builders, bank fit out contractors, safe manufacturers and protective equipment producers specify it for armor doors, armor walls, ballistic windows, bank counters, confidential safes, armor shields, armor vests and ballistic helmets. Sheet at this hardness is slow to fold, weld and cut in a general fabrication shop, so cutting to size and every fixing hole are produced here on laser or water jet equipment. Thickness runs from 2.3mm to 100mm so a light shield panel and a heavy vault section can be specified on the same order.

Why It Is Specified
Key Benefits of Bulletproof Steel Sheet
Hardness Held at 500 to 600 HB
The sheet is typically 500-600 HB, where structural steel may only be half of that. That hardness is what the stated protection levels rest on.
Strength Figures Behind Multi Hit Capacity
Yield strength is 1250 MPa and tensile strength is 1600 MPa. The material data links these figures to a greater multi hit capacity than other steel.
Thin Gauge at the Bottom of the Range
Sheet starts at 2.3mm, which suits shield panels, counter linings and door skins where thickness and weight are tightly limited.
Four Rating Systems on One Specification
FB4+ to FB7, NIJ IIIA to NIJ IV, STANAG 4569 Level 1 and Level 2, and GA-3 to GA-6 are all quoted from the same product, so an export order can be written against whichever system the end client uses.
Cut and Drilled Before It Reaches You
Fixing holes and profiles are produced on a laser machine or water jet. Your workshop assembles instead of fighting the hardness with conventional tooling.
Surface Ready for Paint or Cladding
Sheet is supplied natural or painted, so a door skin can go straight to cladding and a hidden panel can stay in the mill condition.
Problems It Solves
What This Material Removes From Your Process
Conventional Tooling Failing on Hard Sheet
Drills and shears wear out fast at 500-600 HB and hole positions drift. Cutting to size and all fixing holes are produced on laser or water jet equipment before the sheet ships.
End Clients Quoting Different Rating Systems
One project may be written in FB terms and the next in NIJ or GA terms. The same sheet is quoted against FB4+ to FB7, NIJ IIIA to NIJ IV, STANAG 4569 Level 1 and Level 2, and GA-3 to GA-6.
Door and Panel Weight Exceeding the Hinge Rating
Adding thickness to reach a level loads the hinges and the frame. Because ballistic performance at a given thickness improves as hardness increases, the level can be held without adding sheet.
Thin and Thick Sections Sourced Separately
Shield panels and vault sections often come from two suppliers with two sets of paperwork. A single range from 2.3mm to 100mm keeps one specification across the project.
No Paperwork to Hand the End Client
Security work is signed off on documents. A test report is issued for the material supplied so the fabricator has something to pass on.
Application Scenarios
Where It Is Used
Armor Doors and Armor Walls
Steel cores inside security doors and wall linings in banks, embassies, control rooms and detention facilities.
Bank Counters and Ballistic Windows
Counter fronts and window frame sections in cash handling areas built to a named protection level.
Confidential Safes and Vault Sections
Body and door sheet for safes and strongrooms where thicker sections toward 100mm are used.
Armor Shields and Armor Vests
Cut panel work for handheld shields and hard armor plate inserts produced to a stated level.
Ballistic Helmets and Protective Fittings
Formed and cut components for helmets and small protective fittings using the thinner end of the range.
Explosion Proof Project Work
Ballistic and explosion proof projects where the specification calls for armor sheet in fixed structures.

Comparison
Bulletproof Steel Sheet Against the Alternatives
| Structural steel sheet in a security door | Structural steel may be only half the hardness of ballistic steel, so it does not carry the stated protection level at the same thickness. |
|---|---|
| A lower hardness armor grade | As the hardness of bulletproof steel sheet increases the ballistic performance at the same thickness improves, and the price rises with it. |
| Laminated ballistic glass in a counter screen | Steel sheet is used for the opaque sections such as counter fronts and door cores while the glazing handles the vision panel, and both can be specified to the same level. |
| Sheet cut in a general fabrication shop | Folding welding and cutting all get harder as ballistic capability improves, so profiles and holes are produced here on laser or water jet equipment instead. |
Use Guide
Specifying Handling and Welding Notes
- Write the protection level on the drawing in the system your end client uses before selecting thickness
- Send the hole pattern and the profile together so laser or water jet work happens in one operation
- Design welded joints and overlaps at the drawing stage because the sheet is harder to fold and weld than structural steel
- Check door hardware and hinge ratings against the finished panel weight before fixing the thickness
- Keep the test report in the project file so the fabricated item stays traceable
- Handle and store finished panels on edge protection so cut profiles are not damaged before installation
Questions Buyers Ask
Bulletproof Steel Sheet FAQ
How thin can the sheet be for shield and helmet work?
Armor steel sheet starts at 2.3mm and runs up to 100mm, so the thin end of the range covers shields, counter linings and door skins.
Which protection level systems do you quote against?
FB4+, FB5, FB6 and FB7, NIJ IIIA, NIJ III and NIJ IV, STANAG 4569 Level 1 and Level 2, and GA-3 to GA-6. Tell us which system the end client writes in and the order is set against it.
What hardness and strength does the sheet hold?
Hardness is typically 500-600 HB with yield strength of 1250 MPa and tensile strength of 1600 MPa.
Why can we not cut the sheet on our own plasma table?
Ease of folding, welding and cutting decreases as the ballistic capability of the steel improves, so all fixing holes and cutting to size are performed here on a laser machine or a water jet.
Does a thicker sheet always mean a higher level?
Not only thickness. As the hardness of the armor steel plate increases, the ballistic performance of a sheet of the same thickness improves, and the higher hardness also costs more.
What paperwork comes with the order?
A test report is issued for the supplied material and ships with it. Email us with the level, thickness and quantity and the report scope is confirmed on the quotation.
Can we order a small trial sheet first?
Samples are available. Give the thickness and the panel size you want to evaluate and we will confirm what can be released.
