In the high-density urban developments of KL and PJ, smoke extract ducting is the most critical life-safety "exhaust" in your building's M&E infrastructure. During a fire, these ducts must transport toxic gases and heat at temperatures of 250 degrees Celsius or higher without collapsing or leaking. EKG M&E Sdn Bhd specializes in Fire Rated Smoke Extract Ducting, providing engineered solutions that meet strict BS 476-24, EN 1366-1/8, and BOMBA requirements.
Standard ventilation ducting is not designed to handle the thermal expansion and structural stress of a fire. Our fire-rated systems are built to maintain three essential performance standards:
Stability (S): The duct and its support hangers must remain structurally sound and not collapse under the weight of the extraction load while exposed to intense heat.
Integrity (E): The duct must remain airtight, preventing flames or toxic smoke from "leaking" into unaffected compartments (like stairwells or office floors) as it travels to the roof.
Insulation (I): The duct must limit the temperature rise on its outer surface. This prevents the heat inside the duct from igniting nearby combustible materials (like ceiling boards or data cables) through radiant heat.
Mechanical Smoke Spill Systems (10 ACH):
We design ductwork to handle the high-velocity extraction required for the mandatory 10 Air Changes Per Hour (ACH). We ensure the internal friction (static pressure) is minimized so your smoke fans can operate at peak efficiency.
Intumescent Coatings and Wraps:
For retrofits in existing KL buildings, we apply specialized fire-rated sprays or "Rockwool" mineral fiber wraps to standard galvanized steel (GI) ducts. This upgrades their fire rating to 2 hours without requiring a full duct replacement.
Kitchen Grease Extract Fire Ducting:
Commercial kitchens in malls and hotels are high-risk zones. We install fire-rated ducting—often Stainless Steel 304/316—to contain grease fires, ensuring the flames do not spread through the building's ceiling void before the suppression system activates.
Motorized Fire and Smoke Dampers:
At every point where a smoke duct penetrates a fire-rated wall, we install motorized dampers interlocked with the Main Fire Alarm Panel (MFAP). These snap shut (or open, depending on the zone logic) to isolate the fire.

| Joint Sealant | Standard Silicone | Fire-Rated Intumescent Mastic. |
| Hanger System | Standard C-Channel | Reinforced High-Temp Expansion Hangers. |
HVAC & Clean Air Specialist: We perform a full Static Pressure Calculation and Fan Curve Analysis. Because fire-rated coatings add weight and internal resistance, we ensure your Variable Frequency Drive (VFD) controlled fans have the necessary torque to maintain life-saving airflow.
BOMBA Compliance Support: We provide the necessary Material Safety Data Sheets (MSDS) and Installation Certificates (Form G/F) required for your annual Fire Certificate (FC) audit in Malaysia.
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide professional auditing, pressure testing, and maintenance for smoke extraction systems across major commercial and industrial hubs in the Klang Valley.
