In the industrialized landscape of Kuala Lumpur and Selangor, Galvanized Iron (GI) ducting is the essential infrastructure for heavy-duty HVAC, smoke spill, and ventilation systems. EKG M&E Sdn Bhd provides end-to-end GI Duct Fabrication services, transforming high-grade sheet metal into precision-engineered air distribution networks. In a climate where humidity reaches 90%, our fabrication process prioritizes corrosion resistance, structural rigidity, and airtightness to ensure long-term mechanical performance.
Our fabrication workflow combines automated technology with expert craftsmanship to meet international SMACNA and DW/144 standards.
We utilize G90 (Z275) galvanized steel as our baseline material.
Corrosion Shield: The G90 designation ensures a heavy zinc coating ($275\ g/m^2$), which is critical for preventing rust in the Klang Valley’s tropical environment.
Gauge Accuracy: We match the steel gauge (thickness) to the duct dimensions and system pressure requirements to prevent "oil-canning" (vibration noise) and structural sagging.
The integrity of a duct system depends on how the sections are joined.
Integrated Flanges: We utilize automated roll-forming machines to create Transverse Duct Flanges (TDF) directly from the duct wall. This ensures the flange is a continuous part of the metal, eliminating the gaps found in old-fashioned "bolt-on" angle iron frames.
Airtight Sealing: When combined with specialized corner pieces and high-density gaskets, our TDF joints achieve Class C Airtightness, preventing the energy-wasting leaks common in standard metalwork.
No building has perfectly straight paths. Our workshop specializes in bespoke components:
Offsets & Transitions: Precision-cut reducers and S-bends designed to navigate tight ceiling voids in KL high-rises without causing turbulent airflow.
Plenum Boxes: Custom-fabricated mixing chambers with internal acoustic lining to dampen fan noise and ensure even air distribution to branch ducts.
As an HVAC and M&E Specialist, EKG ensures that professional fabrication leads to measurable savings:
TNB Energy Efficiency (VFD Optimization):
Poorly fabricated ducts leak air and create high static resistance. By ensuring an airtight, smooth-flow system, we allow your Variable Frequency Drive (VFD) to run fan motors at lower frequencies (Hz). This direct reduction in motor load results in a significantly lower monthly TNB electricity bill.
BOMBA & Fire Safety Compliance:
Our GI fabrication meets UBBL and BOMBA requirements for non-combustible air paths. We integrate certified fire dampers and use heavy-gauge steel for smoke spill systems to ensure occupant safety during emergencies.
EECA 2024 & GBI Readiness:
High-efficiency ductwork is a core component of the Energy Efficiency and Conservation Act (EECA) 2024. Our systems help lower your Building Energy Index (BEI) and earn valuable Green Building Index (GBI) credits.

Total 3D Coordination: We provide shop drawings that coordinate our GI ducting with other M&E services (firefighting, plumbing, electrical) to ensure a clash-free installation.
Total Performance Commissioning: Post-fabrication and installation, we perform Anemometer Audits and Duct Leakage Tests (DW/143) to certify the system’s efficiency.
Strategic Selangor Support: Based in Kuala Lumpur, our specialized workshop provides rapid turnaround for factories, hospitals, shopping malls, and data centers throughout the region.
