Where to find 600A to 3,000A+ and Heavy Industrial factories in Johor
Most standard developer-built cluster and semi-detached factories in Johor come with 150A to 200A three-phase power and Light or Medium Industrial zoning. If your operation runs plastic injection moulding, metal stamping, CNC machining, cold room compressors, chemical processing or high-density server racks, you need a detached factory with an on-site TNB substation chamber.
| Power Band | Typical Unit Type | Floor Loading | Eave Height | Primary Johor Locations |
|---|---|---|---|---|
| 150A – 300A | Cluster / Semi-D Factory | 10 – 15 kN/m² | 7.5m – 9m | Eco Business Park 1/2/3, Taman Industri Jaya, i-Parc PTP |
| 400A – 800A | Detached Medium Industrial | 15 – 25 kN/m² | 9m – 12m | Senai Industrial Estate, Desa Cemerlang, Kempas, Tebrau |
| 1,000A – 3,000A+ | Detached Heavy / Dedicated Substation | 25 – 50 kN/m² | 12m – 15m (often with crane corbels) | Pasir Gudang, Tanjung Langsat, Senai Airport City, SiLC |
Key specifications to verify before signing a Letter of Offer
- Registered vs. Incoming TNB Capacity: A building may have a 1,000A MSB (Main Switchboard) installed, but confirm whether the current TNB supply is still active or downgraded by the previous tenant.
- Gas Malaysia Pipeline & DOE Buffer: Heavy industrial operations requiring natural gas or generating emissions should prioritize gazetted Heavy Industrial estates in Pasir Gudang, Tanjung Langsat or designated Senai zones.
- Overhead Crane Corbels: Retrofitting a 5-tonne to 20-tonne overhead travelling crane is significantly faster when existing steel columns already include engineered corbels.
