Buyers searching for explosion proof doors usually need a door system designed to resist specified blast effects. For that requirement, the more precise term is a blast resistant door. Its suitability depends on the design threat, tested construction, frame anchorage and installed configuration.
Shenghao Doors supplies steel protective door configurations for project review. Start with the required blast conditions and the doorway's intended use before selecting locks, access control or finish.
A blast resistant door addresses blast loading on the door assembly. This is different from equipment intended to prevent ignition in a hazardous atmosphere and from a venting opening intended to relieve pressure. Use the project's technical brief to identify the correct requirement.
A generic explosion-proof door name cannot establish performance against every explosive charge or standoff distance. Ask the supplier to identify the tested sample and explain how it relates to your proposed door.
The FBM-SHMY sample described in our product guide has a 790 × 1890 × 75 mm leaf. Its structure includes steel facing plates, an internal square-tube framework and rock-wool filling.
| Item | FBM-SHMY tested sample detail |
|---|---|
| Leaf thickness | 75 mm |
| Steel facing plates | 3.0 mm on each side |
| Frame tube | 100 × 50 × 3.0 mm |
| Internal tube framework | 50 × 50 × 2.0 mm |
| Filling | Rock wool |
The guide records a passing outcome under a 1000 g TNT test at a 1.5 m standoff. This result applies to the described sample and test conditions. It must not be presented as a universal rating for different dimensions, double leaves or alternative hardware.
Available proposals include mechanical locks, dual locks, electronic access options and push-bar hardware. Confirm the locking sequence, key control, power-loss operation and compatibility of all locking parts. A hardware change should be reviewed against the required performance rather than treated as a cosmetic substitution.
A separate grille layer can provide a ventilation mode when the solid door is open. Closing only that grille is not equivalent to closing the tested solid protective door. Specify operating states clearly so staff understand when the protective closure is in use.
Provide the opening dimensions, wall thickness, supporting structure and anchorage proposal. The frame transfers loads to its surroundings; the door leaf cannot be assessed in isolation. Confirm leaf handing, threshold, hinges and lock placement in the approved drawing.
Where a project also requires fire resistance, airtightness or special evacuation operation, request separate evidence for those requirements. Rock-wool filling alone does not establish a fire rating.
Send a door schedule with quantities, opening sizes, single- or double-leaf layouts, project location, design threat and relevant specifications. Add access-control needs, finishes, packing and delivery arrangements. A defined brief allows the supplier to identify which configurations require further assessment.
It is the thickness of the described tested sample. Custom construction must be confirmed for the order.
Do not assume that it applies. Ask for the evidence or engineering review relevant to the proposed assembly.
The listed tested sample uses one mechanical lock. Dual-lock images illustrate configurable proposals.
