Founded in 1993, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) has ascended as a global titan in the design and fabrication of platform steel grating, stair treads, and light steel structures. Our 30-year legacy is anchored in a relentless pursuit of engineering excellence and digital manufacturing transformation.
Equipped with 12 state-of-the-art automatic pressure welding lines and a sophisticated robotics suite, we bridge the gap between high-volume production and surgical precision. Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is verified by our role in drafting the YB/T4001 Steel Grating National Standards and our extensive list of international certifications including ISO9001, CE, and GHOST.
The global steel industry is pivoting toward carbon neutrality. NJMM has been recognized as a "Green Factory," utilizing advanced hot-dip galvanization processes that minimize environmental footprint while maximizing the 50-year service life of platform components.
Modern industrial platforms are no longer passive. The integration of IoT sensors for structural health monitoring and the demand for gratings compatible with robotic automated guided vehicles (AGVs) are reshaping design specifications.
While galvanized carbon steel remains the benchmark, there is a rising trend in using specialized Aluminum and Stainless Steel gratings for offshore and chemical environments where extreme corrosion resistance is paramount.
We provide systemic solutions for diverse sectors:
NJMM’s service network spans across South America, Europe, Oceania, and West Asia. We understand the nuances of global procurement:
At NJMM, we are transitioning from a traditional manufacturer to a High-Tech Intelligent Fabricator. Our technical roadmap focuses on three core pillars:
Implementation of AI-optimized laser cutting and digital tailoring to reduce material waste by 15% and increase structural integrity of irregular-shaped gratings.
Expansion of our 6 sets of automatic banding robots to ensure 100% weld consistency across every platform unit.
Development of ultra-lightweight composite-coated steel gratings for high-altitude projects where windage resistance and weight are critical factors.
Widely used in port terminals, shipbuilding, military engineering, and airport offshore projects. NJMM products like JG1008/30/100 are engineered for the most demanding loading requirements.
Serrated steel gratings provide maximum safety in oily or wet environments. Essential for stair treads (JT1-JT8) and chemical plant flooring.
