Question 1

What is the difference between bulletproof and bullet resistant steel doors?

Accepted Answer

There's no such thing as a truly bulletproof door — and any manufacturer who tells you otherwise isn't being straight with you. The correct term is bullet resistant, because every rated system is designed to stop a specific threat at a specific velocity and shot count. Something more powerful can always exceed the tested criteria. UL 752 defines 10 protection levels, each tied to a specific caliber, round type, number of shots, and shot grouping. A Level 1 door is rated for 9mm FMJ handgun fire. A Level 10 door is rated for .50 caliber rifle. The goal is matching the level to the realistic threat — not over-specifying out of fear or under-specifying out of budget pressure. We'll help you figure out which level actually makes sense for your building and your situation.

Question 2

What UL 752 level do I need for a school, bank, or government building?

Accepted Answer

For most K–12 schools and retail banking environments across the United States, UL 752 Levels 1 through 3 are the standard specification range. These levels address handgun-level threats, which account for the majority of traced firearms in the U.S. according to ATF data. For government facilities subject to ISC security level requirements, or for installations where rifle threats are a realistic concern — courthouses, military buildings, currency exchanges, critical infrastructure — Levels 4 through 8 are more appropriate. Levels 9 and 10 are reserved for extreme or defense-grade applications. The right answer depends on a real threat assessment, not a default assumption. If you're unsure, we can walk you through the decision.

Question 3

Can a bullet resistant steel door also stop forced entry attempts?

Accepted Answer

Not automatically — and this is one of the most important things to understand before you specify a door. Ballistic resistance and forced entry resistance are tested under completely different standards. A door can pass UL 752 testing and still be vulnerable to a pry bar, battering ram, or fire axe. Our forced entry steel door systems are designed to address both threats in a single assembly, with compliance options under ASTM F1233 and the newer ASTM F3561-22 standard — which specifically evaluates forced entry resistance after a simulated active shooter attack. If your threat environment includes any scenario where someone might shoot at a door and then attempt to breach it physically, a multi-threat assembly is worth specifying from the start.

Question 4

What is a non-ricochet steel door and why does it matter?

Accepted Answer

A non-ricochet door is engineered to capture and retain the attacking projectile inside the door assembly rather than allowing it to deflect or pass through in a way that creates secondary hazards. This matters because a door that stops a bullet but sends fragments or ricochets back into the protected space isn't fully doing its job. Every bullet resistant steel door we manufacture is designed as a non-ricochet assembly — the ballistic armor integrated into the door and frame is specifically constructed to absorb and contain the round. For environments where employees, students, or customers are standing close to the barrier, this engineering detail is a meaningful safety distinction that most manufacturers don't address directly.

Question 5

How heavy is a bulletproof steel door, and does that affect installation?

Accepted Answer

Yes, weight is a real installation consideration. A complete ballistic steel door and frame assembly can weigh approximately 100 pounds or more depending on the protection level — significantly heavier than a standard commercial steel door. This is why our assemblies use heavy-duty clear anodized aluminum continuous gear hinges rated for the door's weight, and why the frame construction matters as much as the door panel itself. The frame face carries 2 inches of ballistic armor on cold-rolled, prime-painted steel — it's not a standard hollow metal frame. We ship assemblies factory pre-hung so the critical structural relationships are set before the door reaches your job site, reducing the risk of installation errors that could compromise the system's integrity.

Question 6

Can bulletproof steel doors be customized to fit existing openings and hardware?

Accepted Answer

Yes, and this is where our in-house CAD design capability makes a real difference. Our standard door size is 3' x 7', but we fabricate custom sizes for any opening. Hardware preps are configured to accommodate cylindric locksets, mortise locksets, exit devices, and electrified access control — so the door integrates with whatever access control or security system you're already running. Glazing options range from 1" to 2-3/16" thickness depending on the protection level, and sidelights and transoms are available for storefront-style configurations. Our CAD designers work directly with architects and general contractors throughout the specification process, which means the door you receive is engineered for your opening — not adapted from a catalog item that's close enough.
