Decoding the Expertise of Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM)
Founded in 1993, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) has evolved from a regional manufacturer into a global powerhouse in the design and production of stainless steel open grid flooring, railings, and light steel structures. Our footprint spans two massive production bases in East and North China, powered by 12 automated pressure welding lines.
By integrating advanced robotics welding, laser cutting, and digital control panel tailoring, we ensure every panel of stainless steel open grid flooring meets rigorous international standards, including ISO9001, CE, and GHOST. Our commitment to the E-E-A-T principle ensures that every procurement officer, engineer, and project manager receives not only a product but a certified engineering solution.

We utilize premium AISI 304 and 316L stainless steel, offering unmatched corrosion resistance in marine and chemical processing environments. Our forge-welded technology ensures molecular bonding for maximum structural rigidity.
Designed to satisfy high-load requirements (JG505 to JG1008 series), our grid flooring optimizes the strength-to-weight ratio, reducing the stress on supporting steel structures by up to 30% compared to solid plating.
With an open area ratio of over 70%, our grid flooring facilitates rapid drainage, superior ventilation, and easy cleaning—critical for food processing and pharmaceutical sectors.
The global demand for Stainless Steel Open Grid Flooring is shifting toward suppliers who can provide Information Gain—meaning value-added insights into project-specific customization. As a leading China factory, NJMM leverages local supply chain synergies to offer pricing advantages without compromising on quality. Our "Green Factory" designation (awarded in 2021) aligns with global ESG requirements, ensuring that your procurement process supports sustainable manufacturing.
Navigating international building codes can be complex. NJMM simplifies this by adhering to YB/T4001 (2019 edition), which we helped draft, alongside ASTM and BS standards. We provide localized technical support through detailed CAD drawings and installation guides, ensuring that "Made in China" translates to "Engineered for Excellence" in your local jurisdiction.
Platform walkways and ditch covers for oil rigs and shipbuilding, where salt-spray resistance is paramount.
Ventilation screens and equipment protection in environments exposed to volatile chemicals and high temperatures.
Hygienic flooring solutions that allow for rigorous wash-down procedures without risk of oxidation or bacterial harborage.
Modern ceilings, sunshades, and urban ditch covers that combine aesthetic appeal with structural durability.
The industry is moving towards Smart Infrastructure. NJMM is at the forefront of this shift, integrating digital twin technology into our design phase. This allows for precision tailoring of irregular grating panels, reducing on-site waste and shortening construction periods. Furthermore, the trend toward Carbon Neutrality is driving us to optimize our hot-dip galvanization and stainless steel pickling processes to minimize environmental impact.
