Class A Steel Security Door Test Report: Steel Thickness, Locking & Security Performance
Class A Steel Security Door: What Does the Test Report Show?
A steel security door is more than a steel door leaf and a lock. Its security performance depends on the complete door assembly, including the steel panels, frame, locking system, hinges and structural connections.
For B2B buyers, distributors, contractors and project developers, a test report can provide useful technical evidence when evaluating a security door supplier.
This article reviews a test report for a Class A steel security door (甲级钢质防盗门). The tested sample was approximately 2150 × 980 mm and was evaluated according to GB 17565-2007, General Specification for Burglary Resistant Safety Door. The report records an overall qualified result for the tested sample.
Important: The report was issued in December 2022 under GB 17565-2007. That standard has since been replaced by GB 17565-2022, which came into effect on January 1, 2024. Therefore, this report should be understood as technical test evidence for the specific sample tested at that time, rather than as a statement of current compliance with GB 17565-2022.
Test Report Overview
The report provides the following basic information about the tested steel security door:
| Item | Test Report Details |
|---|---|
| Product | Steel Security Door |
| Security Grade | Class A / 甲级 |
| Sample Size | Approx. 2150 × 980 mm |
| Test Standard | GB 17565-2007 |
| Report No. | J22-002220 |
| Overall Conclusion | Qualified |
The report was issued by the Guangxi Zhuang Autonomous Region Testing Institute of Product Quality.
The information above describes the specific sample and test configuration recorded in the report. It should not be interpreted as applying automatically to every steel security door model or every customized configuration.
Steel Thickness and Door Construction
The steel construction of the tested door was one of the measured technical items.
The report records the following measured steel thicknesses:
| Component | Required Thickness in Report | Measured Result |
|---|---|---|
| Door Frame | 2.00 mm | 1.94 mm |
| Outer Door Panel | 1.00 mm | 1.12 mm |
| Inner Door Panel | 1.00 mm | 0.88 mm |
The results were recorded as qualified according to the applicable requirements for the tested sample.
The report also describes the sample as a fully enclosed steel security door. The door structure included steel panels, a steel frame, a multi-point locking system and reinforced protection around the lock installation area.
For B2B sourcing, steel thickness should be considered together with the frame construction, reinforcement, locking system and hinge configuration rather than used as the sole indicator of security performance.
Class A Security Grade
The tested product is identified in the report as a Class A steel security door.
The report's security-grade item was judged qualified against the applicable requirements of GB 17565-2007.
It is important to understand what this classification means.
Class A / 甲级 in this report refers to the security classification under the Chinese standard used for the test. It should not be assumed to be a universal international security classification or directly equated with security ratings used in other countries.
For international projects, buyers should always confirm which security standard and performance requirements apply in the destination market.
Multi-Point Locking System
The locking system is one of the most important structural components of a steel security door.
According to the report, the tested door had:
- 16 locking points in total
- 14 horizontal locking bolts
- 2 vertical locking bolts
- Main locking points with a recorded length of 26 mm
- A reinforced steel protection plate around the lock installation area
The report records the locking-system requirements as qualified.
The multi-point configuration distributes the locking points along the door assembly instead of relying only on a single central locking position.
For project buyers, this makes the locking configuration an important specification to confirm when comparing different steel security door models.
Anti-Destructive Performance
Anti-destructive performance is a major part of the test report.
The report includes a specified 30-minute destructive-resistance test for key parts of the door assembly.
Lock Performance
The test included destructive methods applied to the locking area under the conditions specified in the standard.
The report records the lock-related anti-destructive performance as:
Qualified
Hinge Performance
The hinge side of the door was also evaluated through the specified destructive test procedure.
The report records the hinge-related anti-destructive performance as:
Qualified
These results indicate that the tested sample met the applicable anti-destructive requirements recorded in the report.
They should not be interpreted as a guarantee that every possible attack method or every customized door configuration will produce the same result.
Dimensional Accuracy and Door Fit
The report also evaluates several dimensional and assembly-related characteristics.
The recorded results include:
| Measurement | Test Result | Conclusion |
|---|---|---|
| Door leaf diagonal deviation | 1.0 mm | Qualified |
| Door leaf/frame fitting gap | 2.2 mm | Qualified |
| Lock tongue/lock seat gap | 1.4 mm | Qualified |
| Door leaf/frame active fitting gap | 3.0 mm | Qualified |
| Locking-point surface flatness | 22 mm | Qualified |
These measurements are relevant to the manufacturing accuracy and assembly of the tested door.
Proper dimensional control helps ensure that the door leaf, frame, locking system and hinges work together as designed.
For OEM projects, the final dimensions and tolerances should be confirmed against the project drawings and installation conditions before production.
Impact and Mechanical Performance
In addition to anti-destructive testing, the report includes several mechanical performance tests.
Soft Impact Performance
The tested door recorded a residual deformation of:
2.2 mm
The result was judged qualified.
End Impact Performance
The reported deformation after the specified end-impact test was:
1.2 mm
The result was also judged qualified.
Hinge Flexibility
The hinge flexibility test was recorded as:
Qualified
The report further records that the hinge could maintain the required operating performance under the specified test conditions.
These results provide additional technical information about the mechanical behavior of the tested door assembly.
Lock Protection and General Locking Requirements
The report includes a specific lock protection requirement.
It records a reinforced steel protection plate around the lock installation area and evaluates the locking system against the applicable requirements.
The report also records:
16 locking points, including 14 horizontal locking bolts and 2 vertical locking bolts.
The locking-point quantity exceeded the minimum requirement stated in the report, and the overall locking-system item was judged qualified.
For security door sourcing, buyers should look beyond the lock brand alone and evaluate the complete locking structure, including the lock body, locking points, reinforced areas and connection with the door frame.
Electrical Safety: Not Applicable to This Sample
The report also includes an electrical safety section.
However, the tested sample had no electrical components, so the electrical safety test was recorded as not applicable.
This distinction is important when reading a technical report.
A professional test-report review should distinguish between:
- Qualified
- Not applicable
- Not tested
Rather than presenting every item as a product performance claim.
What Does This Test Report Actually Demonstrate?
A test report is useful only when its scope is understood correctly.
The report provides evidence that the tested sample:
- Was identified as a Class A steel security door under the applicable test standard.
- Had the documented steel thickness measurements.
- Used a 16-point locking configuration.
- Passed the specified locking-system requirements.
- Achieved qualified results in the reported anti-destructive tests for the lock and hinges.
- Met the reported dimensional and mechanical requirements.
- Received an overall qualified test conclusion.
The report does not automatically demonstrate that:
- Every Zonle Doors steel security door has the same construction.
- Every current model complies with GB 17565-2022.
- A customized OEM door has exactly the same performance as the tested sample.
- The product automatically meets security regulations in every export market.
- The 2022 test report is a current certification for all future production.
This distinction is particularly important for international B2B buyers.
When a project has specific security requirements, the supplier should confirm the exact model, materials, hardware, dimensions and applicable standards before production.
GB 17565-2007 vs. GB 17565-2022: What Buyers Should Know
The test report was issued under GB 17565-2007.
According to China's National Standard Information Public Service Platform, GB 17565-2007 was officially replaced by GB 17565-2022, which was published on December 1, 2022 and implemented on January 1, 2024. GB 17565-2007 is now listed as withdrawn.
This means that the report remains useful as a historical technical record of the tested sample, but it should not be presented as evidence that the same product configuration currently complies with the latest standard.
For new projects requiring compliance with current Chinese requirements, buyers should request documentation applicable to the current GB 17565-2022 standard.
For export projects, additional local or project-specific requirements may also apply.
What Should Buyers Check When Sourcing Steel Security Doors?
A reliable security door supplier should be evaluated based on more than product appearance or a single specification.
1. Steel Construction
Confirm the steel panel thickness, door frame construction and internal reinforcement.
2. Locking System
Check the number and configuration of locking points, lock protection and the connection between the lock and door frame.
3. Hinge Structure
The hinge side should provide appropriate structural support alongside the locking side.
4. Test Standard
Confirm which standard was used for testing and whether it is applicable to the current project.
5. Test Sample
Check whether the tested sample has the same dimensions, materials, hardware and construction as the production model.
6. Current Documentation
For new projects, request the latest applicable test reports, certificates and technical specifications where required.
7. Project Requirements
Security requirements can vary by country, building type and application. Fire resistance, acoustic performance, thermal insulation, weather resistance and other requirements may need separate documentation.
For this reason, a test report should be treated as one part of the supplier evaluation process, rather than the only qualification criterion.
