In the evolving landscape of global infrastructure, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) stands as a vanguard of technical innovation and manufacturing excellence. Established in 1993, NJMM has transitioned from a specialized steel grating producer to a global powerhouse in light steel structures, trench covers, and safety platforms.
As a leading Wholesale Steel Grating Cover Supplier, our role extends beyond mere fabrication. We provide high-gain information and structural integrity for the world's most demanding environments—from offshore oil rigs to high-tech pharmaceutical cleanrooms. Our commitment to the E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) principles is validated by our 30-year track record and our active participation in drafting the YB/T4001 Steel Grating Standard.
Leveraging 12 automated pressure welding lines and robotic assembly, we ensure dimensional tolerances that exceed international standards like ASTM, BS, and AS/NZS.
Our Hot-Dip Galvanizing process provides superior anti-corrosion protection, verified by ISO 9001:2015 and CE certifications for diverse global markets.
Serving over 13+ service networks globally, NJMM exports more than 20,000 tons annually to South America, Europe, West Asia, and beyond.
Our production bases in East and North China utilize Factory 4.0 principles. With laser cutting, digital control tailoring, and AI-driven quality inspection, we minimize waste and maximize output efficiency, reaching 50,000 metric tons annually.
For global enterprises, procurement risk is mitigated through our strategic raw material reserves and dual-base manufacturing redundancy. This ensures "Just-in-Time" delivery even during global logistics fluctuations.
Recognized as a "Green Factory" in 2021, NJMM integrates eco-friendly waste disposal and energy-efficient welding technologies, aligning with global carbon neutrality goals.
The future of Steel Grating Covers lies in material science and smart integration. NJMM is currently pioneering research into:
We provide systemic solutions for Petrochemical, Mining, Shipbuilding, and Urban Infrastructure. Our engineering team provides detailed 3D installation drawings, ensuring that our products integrate perfectly with your existing light steel structures.
NJMM Platform Walkway Application: High ventilation, lighting, and heat dissipation efficiency.
Our products adhere to ISO 9001, ISO 45001, ISO 14001, CE, and GHOST certificates. We understand the specific regulatory requirements of the Middle East, European, and South American markets.
We help global procurement officers optimize their Total Cost of Ownership (TCO) by providing long-lifecycle products that require zero maintenance and offer easy, clip-based installation.
