Founded in 1993, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) has evolved into a cornerstone of the global industrial walkway and steel grating landscape. With nearly three decades of dedicated research and engineering, we specialize in the design and fabrication of steel grating, safety railings, industrial platforms, and complex light steel structures. As a modern comprehensive enterprise, we integrate scientific innovation with precision manufacturing.

Operating from two massive production bases in East and North China, NJMM utilizes 12 state-of-the-art automatic welding lines. Our technical arsenal includes robotic welding systems, high-precision laser cutters, and digital control panels that ensure every millimeter of our walkway mesh meets the rigorous demands of offshore, mining, and petrochemical environments.
The global demand for walkway mesh is no longer just about "filling a gap." Procurement managers today focus on Total Cost of Ownership (TCO). In regions like North America and the EU, buyers are prioritizing corrosion resistance (hot-dip galvanization per ASTM A123) and slip resistance (serrated surfaces). As a premier China Walkway Mesh Manufacturer, NJMM addresses these needs by providing engineering support that reduces onsite installation time by up to 30%.
Our G505/30/100 and JG1008/30/100 series are engineered for ports and heavy-duty industrial docks, supporting both vehicular and pedestrian traffic with zero structural fatigue.
Steel grating consumes significantly less material than solid flooring, offering superior ventilation and lighting, which reduces energy costs in industrial plants.
Certified by CE and GHOST, our products meet international occupational health standards, reducing workplace accidents via superior drainage and anti-skid designs.
Modern industrial projects in the petrochemical, textile, and refinery sectors require integrated solutions. NJMM doesn't just sell mesh; we provide modular platform systems. Our technical roadmap involves moving from traditional bar grating to AI-assisted layout designs that minimize material waste. By participating in the revision of the YB/T4001 steel grating standard, NJMM has positioned itself as an industry authority, influencing how safety and load-bearing capacity are measured globally.
The future of walkway mesh lies in "Smart Infrastructure." NJMM is currently exploring the integration of IoT sensors within heavy-duty gratings to monitor structural integrity in real-time on offshore platforms. Furthermore, our transition to "Green Factory" status in 2021 highlights our commitment to low-carbon steel processing, aligning with global ESG requirements for Tier 1 suppliers.
With a service network spanning South America, Europe, Oceania, and the Middle East, we understand regional nuances. Whether it's the high salinity of offshore projects in Brazil or the extreme thermal fluctuations in West Asian refineries, our "Longta" brand gratings are customized for local environmental conditions. We provide detailed engineering drawings and installation guides, ensuring that the transition from manufacture to implementation is seamless.
