With Indonesia's transition to the new capital city, Ibu Kota Nusantara (IKN), and the massive expansion of the Trans-Java and Trans-Sumatra toll roads, the demand for high-load-bearing, corrosion-resistant steel grating has reached an all-time high. Our solutions are engineered specifically to meet the unique seismic and soil conditions found across the archipelago, ensuring longevity in both the Port of Tanjung Priok and the high-altitude mines of Papua.
Indonesia's tropical climate—characterized by high humidity, salt-laden sea air, and frequent rainfall—demands superior galvanization standards. As a premier manufacturer, NJMM utilizes advanced hot-dip galvanization that exceeds ISO 1461 standards, offering a protective zinc coating that withstands Indonesia’s 90%+ humidity levels and marine-intensive environments like the Sulawesi nickel smelters.
The Indonesian mining sector, particularly Nickel, Coal, and Gold, requires industrial platforms that can handle extreme dynamic loads. Our forge-welded steel grating provides the ultimate structural integrity for conveyor walkways, ventilation covers, and heavy-duty drainage systems in Kalimantan's mining pits and refinery plants.

International procurement for Indonesian projects often faces challenges in logistics and compliance. NJMM bridges this gap by offering Technical Roadmap Support, providing detailed CAD/BIM drawings and customized grating layouts that reduce on-site cutting and labor costs in Indonesia.
As Indonesia pushes for "Green Industrial Estates," NJMM has been recognized as a "Green Factory." Our production processes optimize steel consumption—using less material to achieve higher loading requirements—directly contributing to the carbon reduction goals of our Indonesian partners.
We ensure our products meet not only international standards (ASTM A123, BS 4592) but also align with the rigorous safety and quality expectations of Indonesian state-owned enterprises (BUMN) involved in oil, gas, and power generation.
For refineries in Balikpapan or Cilacap, our JG255/30/100 and JG325/30/100 gratings are the gold standard. They provide excellent ventilation, heat dissipation, and explosion-proof properties. The hot-dip galvanization finish ensures that even in volatile chemical environments, the structures remain corrosion-free for decades.
Addressing Indonesia's urban flood management, our trench covers offer superior drainage capacity. Designed for heavy traffic loads (T-20, T-25), these are widely used in commercial developments in Surabaya and Medan, combining aesthetic appeal with industrial strength.

Engineered for Indonesian Industrial Specifications
NJMM is committed to the digital transformation of the steel industry. Our 2025 Roadmap for the Indonesian market includes:
Depending on the volume and customization, NJMM typically ships within 15-30 days from our Ningbo base. Transit time to Jakarta or Surabaya ports is usually 10-14 days.
Yes, while our products are manufactured to ISO and ASTM international standards, we ensure that the material grades and galvanization thicknesses meet or exceed the requirements specified in Indonesian industrial tenders.
Absolutely. Our in-house engineering team provides full CAD support, designing grating layouts that optimize material usage and simplify installation on-site.
Forge-welding uses heat and pressure to fuse crossbars and bearing bars into a single unit, providing superior structural integrity—ideal for the high-vibration environments of Indonesian power plants and processing facilities.
