Fire-Rated Container Units
For fire-isolated storage of combustible materials and equipment. All sides and the ceiling use 120 mm fire walls, paired with a fire door or fire roller shutter.
A modular solution for hazardous-material storage and personnel refuge. Three product series cover fire-isolated storage, explosion-venting fire-rated storage, and temporary personnel shelter.

The product range uses two base container types—20GP and 20HC—and comprises nine standard models.

For fire-isolated storage of combustible materials and equipment. All sides and the ceiling use 120 mm fire walls, paired with a fire door or fire roller shutter.

For storage of flammable chemicals with deflagration risk. Uses fire blast walls and a lightweight venting wall; the venting configuration uses TKC-01 fasteners and restraint cables, subject to project technical documentation.

For temporary refuge near explosion-hazard areas. All sides and the ceiling use fire blast walls, paired with a fire blast door and no venting surface.
6058×2438×2591 mm · For A / B / DLC-A / DLC-B / C models
6058×2438×2896 mm · DG hazardous-material unit with standard sump; for A / B / DLC-A / DLC-B models
Hinged door at short-end B2
Fire roller shutter at long-side A2 for forklift/full-pallet access
20GP-only personnel shelter
Explosion-venting models configured with a venting wall
A / B / DLC / C models share the 120 mm fire blast wall construction. A / B models use fire doors without blast design; final fire resistance is determined by project requirements.

h fire resistance
| Door type | Fire resistance | Blast resistance | 20GP size | 20HC size | Application |
|---|---|---|---|---|---|
| Fire door | ≥1.5 h | — | 2010×2170 mm | 2010×2420 mm | TKC-20GP-A / 20HC-A |
| Fire blast door | ≥1.5 h | 300 kPa | 2010×2170 mm | 2010×2420 mm | DLC-A, TKC-20GP-C |
| Fire roller shutter | ≥3 h | DLC-B additionally rated 1 MPa blast | 5600×2170 mm | 5800×2650 mm | B models |

Confirm both the standard door-system table and the exact model configuration against the project design. The standard configuration for TKC-20HC-DLC-B uses a 5600×2400 mm fire roller shutter.
Areas are reference configuration areas for fire/blast walls and venting walls; the final project follows the formal technical proposal and contract.
