Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) was founded in 1993, is mainly engaged in the design and manufacturing of steel grating, railings, platforms and other light steel structures. It is a modern comprehensive enterprise integrating scientific research and design, machinery manufacturing and engineering construction.
We currently have 2 production bases in the East and North of China, there are 12 steel grating auto welding product lines, as well as complete auxiliary processing equipment and testing facilities, like robots welding, laser cutting, digital control panel tailoring etc. Our annual output of steel gratings and allied products, including trench covers, stair treads, stanchions, handrails, fences, is over 50,000 metric tons.

NJMM offers engineering service and support, including the design and installation of the grating solutions and the provision of detailed drawings if required. NJMM had got the ISO9001 Quality System Certificate, CE certificate, GHOST certificate and other international certificates.
Metro Manila, the economic heart of the Philippines, is currently undergoing a historic transformation. With the government’s "Build Better More" program, massive projects like the Metro Manila Subway, the North-South Commuter Railway (NSCR), and the modernization of the Manila North Harbor are creating an unprecedented demand for high-durability steel components. Steel grating is no longer just a flooring material; it is a critical component for public safety, drainage efficiency, and maintenance access in high-density urban environments.
Strategic procurement is vital for Manila-based contractors. Located in Ningbo, NJMM benefits from one of the world's busiest deep-water ports. This proximity allows for direct shipping routes to Manila North/South Harbor, reducing lead times to as little as 7-10 days transit. Our "China Factory to Manila Site" model eliminates middleman markups, ensuring that Philippine developers receive Tier-1 quality at competitive pricing.
As we look toward 2030, the steel grating industry is shifting from "commodity manufacturing" to "smart engineering." NJMM is leading this transition with three core pillars:
A. Automated Precision: We have integrated 12 self-developed automatic pressure welding lines. This technology ensures that every weld point on our gratings is fused at the molecular level, preventing the structural fatigue often seen in manually welded local alternatives in Manila.
B. Green Steel Initiatives: Environmental compliance is becoming a strict requirement in Philippine construction. NJMM is optimizing its galvanizing process to reduce waste and utilizing recyclable high-grade steel to help project owners achieve LEED certification for new developments in areas like Bonifacio Global City (BGC).
C. BIM-Ready Design: We provide detailed 3D CAD and BIM models for large-scale Manila infrastructure projects. This allows for "Zero-Error" installation, where gratings arrive on-site pre-cut to the exact dimensions of the complex structural frames of modern subway stations.
NJMM markets its products mainly to South America, Europe, Oceania, Africa, Southeast Asia, and the Middle East. Our annual capacity of over 50,000 tons ensures we can handle Manila's largest infrastructure needs without delay.
With 6 sets of automatic banding robots and 2 irregular grating fabrication platforms, we achieve precision that exceeds international standards like YB/T4001 and ASTM A123.
ISO9001:2015, ISO45001:2018, and CE certified. We participated in drafting the industry standards, proving our role as an industry benchmark.
The products are widely used in Petrochemical Industry, Light Chemical Industry, Mechanochemistry, Textile Chemical Industry, Refinery, Port Terminals, Steel Industry, Mining, Shipbuilding, Airport Engineering, and Offshore Projects.
