In the demanding industrial and commercial sectors of Kuala Lumpur and Selangor, Galvanized Iron (GI) ductwork remains the gold standard for robust, long-term air distribution. As a premier HVAC and M&E Specialist, EKG M&E Sdn Bhd provides precision-engineered GI solutions designed to withstand high static pressures and the intense 90% humidity of the Klang Valley. Whether for centralized cooling, smoke spill systems, or kitchen exhausts, our GI ductwork is fabricated to ensure structural integrity and maximum airflow efficiency.
GI ductwork is fabricated from high-quality steel sheets coated with a protective layer of zinc. This "Galvanized" barrier is essential for preventing rust and ensuring the system lasts for decades.
We prioritize the use of G90 Grade (Z275) galvanized steel.
Superior Corrosion Resistance: G90 steel features a thicker zinc coating () compared to standard commercial grades. This is critical in Malaysia to prevent "white rust" and pitting caused by constant moisture and condensation.
Sacrificial Protection: If the duct surface is scratched during installation, the zinc layer chemically "sacrifices" itself to protect the underlying steel, maintaining the structural life of your HVAC network.
The strength of a metal duct system depends on its joints.
Airtight Flange Systems: We utilize Transverse Duct Flange (TDF) or TDC jointing. These flanges are roll-formed directly onto the duct, creating a rigid, uniform connection that, when paired with high-density gasketing, achieves Class C Airtightness.
Structural Rigidity: For large-span ducts, we implement cross-breaking (kinking) or internal tie-rod reinforcements to prevent "oil-canning" noise and wall deflection under high-pressure loads.
As an HVAC and Energy Specialist, EKG ensures your GI ductwork supports your facility's bottom line:
TNB Energy Savings (VFD Load Reduction): Leaky joints in traditional metalwork are a primary cause of energy waste. By ensuring an airtight seal, we minimize air loss. This allows your Variable Frequency Drive (VFD) to run fan motors at lower frequencies (Hz). According to the Cube Law of centrifugal loads, reducing fan speed slightly leads to massive reductions in your monthly TNB electricity bill.
Fire Safety & BOMBA Compliance: Galvanized iron is inherently non-combustible. Our GI systems are engineered to meet the Uniform Building By-Laws (UBBL) and BOMBA requirements for fire-rated zones, smoke extraction, and kitchen exhaust systems.
EECA 2024 & GBI Alignment: Our high-efficiency fabrication methods help buildings lower their Building Energy Index (BEI), meeting the mandates of the Energy Efficiency and Conservation Act (EECA) 2024 and earning credits for Green Building Index (GBI) certification.
Turnkey Engineering: From 3D CAD shop drawings and factory fabrication in our Selangor workshop to on-site hanging and commissioning.
Total Performance Commissioning: Post-installation, we perform professional Duct Leakage Tests (DW/143) and Anemometer Audits to certify your system is delivering the exact air volume required.
Strategic Selangor Support: Based in Kuala Lumpur, we provide turnkey GI ducting services for data centers, hospitals, shopping malls, and industrial facilities throughout the region.
