In the modern industrial landscape, Steel Open Mesh Flooring (also known as bar grating) serves as the backbone of infrastructure in oil rigs, power plants, and chemical facilities. As energy and mining sectors expand globally, the demand for gratings that balance high load-bearing capacity with minimal weight has surged.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM), established in 1993, has transitioned from a local manufacturer to a global standard-setter. By participating in the revision of the YB/T4001 steel grating standard in 2019, NJMM demonstrated its technical leadership and industry authority.
Unlike standard suppliers, NJMM provides Information Gain through custom-engineered drainage calculations, wind-resistance analysis for high-altitude platforms, and proprietary hot-dip galvanization techniques that exceed ISO 1461 requirements for extreme environments.
NJMM is a modern comprehensive enterprise integrating scientific research and design, machinery manufacturing, and engineering construction. We own 12 steel grating auto welding product lines, supported by robots welding, laser cutting, and digital control panel tailoring. Our service network spans South America, Europe, Oceania, and the Middle East, making us a preferred global partner.
Located in the heart of China’s steel manufacturing hub, NJMM leverages a hyper-efficient supply chain. Our "Green Factory" certification (2021) isn't just a badge; it's a testament to our resource optimization. We maintain a raw material buffer that mitigates global market fluctuations, ensuring reliable delivery times even during global logistics crises.
With 6 sets of automatic banding robots and 2 sets of irregular grating fabrication platforms, we handle complex geometric designs that others refuse. This digital-first approach reduces human error and accelerates the transition from CAD drawing to finished product by 30% compared to traditional manual factories.
For North Sea oil rigs or Southeast Asian offshore wind farms, NJMM provides heavy-duty hot-dip galvanized gratings. Our coating thickness is specifically engineered to resist salt-spray corrosion, extending service life to over 20 years.
Recommended: JG325/30/100, G505/30/100.
In Australian or Chilean mines, steel gratings must withstand heavy vehicle loads and falling debris. Our forge-welded serrated bar gratings offer maximum anti-slip protection and structural integrity under vibration.
Recommended: JG705/30/100, JG1008/30/100.
Modern transit hubs in Europe and North America utilize steel mesh for both drainage and aesthetics. NJMM’s laser-cut precision allows for decorative yet functional ceiling panels and ventilation screens.
Recommended: Plain type forge welded, Aluminum I-Bar.
Transitioned from manual welding to 12 self-developed automatic pressure welding equipment lines. Achieved ISO9001:2015 and CE certification.
Integration of banding robots and AI-driven quality inspection. Inclusion in the "specialized and special new enterprises" cultivation pool.
Future focus on recycled steel integration and low-VOC galvanizing processes to meet EU Carbon Border Adjustment Mechanism (CBAM) requirements.
NJMM is committed to a continuous process to enhance customer service through product quality and delivery. We hold ISO45001:2018 (Occupational Health), ISO14001:2015 (Environmental), and GHOST certificates.
