GI Duct Fabrication by EKG M&E Sdn Bhd

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.

The Precision Fabrication Process

Our fabrication workflow combines automated technology with expert craftsmanship to meet international SMACNA and DW/144 standards.

1. Material Selection (G90 Premium Grade)

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.

2. Automated TDF/TDC Flange Forming

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.

3. Custom Fittings & Transitions

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.

Critical Operational & Energy Benefits

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.
