High-performance stair treads and bar gratings designed for industrial resilience.
Modern procurement has shifted from "lowest price" to "Lifecycle Cost Efficiency." Global infrastructure projects in the Middle East, North America, and Southeast Asia now demand Information Gain regarding material traceability and carbon footprint. Industrial steel steps are no longer just components; they are critical safety assets integrated into BIM (Building Information Modeling) workflows.
Anti-slip performance is now a non-negotiable legal requirement. With the rise of the ISO 45001 standard for occupational health and safety, manufacturers like NJMM are pioneering advanced serrated surfaces and specialized nosing designs (JT series) to minimize workplace injuries in high-moisture and oil-rich environments.
The industry is moving toward "Green Steel." Hot-dip galvanization techniques have evolved to be more eco-friendly, offering 50+ years of corrosion resistance without maintenance, drastically reducing the environmental impact over the asset's lifespan.
Founded in 1993, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) has established itself as a global powerhouse in the design and manufacturing of steel grating and light steel structures. As a modern comprehensive enterprise, NJMM integrates scientific research, robotics-led machinery manufacturing, and engineering construction.
With two massive production bases in East and North China, our infrastructure includes 12 automated pressure welding lines, 6 banding robots, and laser cutting systems. Our annual output exceeds 50,000 metric tons, serving clients across South America, Europe, Oceania, and the Middle East.
Widely deployed in Petrochemical, Mining, Shipbuilding, and Offshore Engineering. Our solutions satisfy extreme loading requirements under specific environmental conditions, preventing the accumulation of grime, snow, and water.
NJMM holds ISO9001:2015, ISO45001:2018, and ISO14001:2015 certifications. Our products are CE and GHOST certified, ensuring compliance with international safety and environmental laws.
NJMM provides more than just hardware; we provide global engineering support. From providing detailed technical drawings to onsite installation guidance, our service network covers all major industrial hubs. Our logistics team ensures that 20,000+ tons of export volume reach their destination with full compliance documentation, reducing customs delays for our partners.
Our competitive advantage lies in "Information Gain"—we provide comprehensive data on load-bearing capacities, anti-corrosion life expectancy, and material origin. Unlike standard manufacturers, NJMM uses 12 automated welding lines that ensure 100% penetration and structural consistency, minimizing weld failures.
We offer specialized "JT" series configurations (JT1 to JT8). These variants allow for different nosing types (serrated, checker plate) and fixing methods (welding or bolting), ensuring the product meets specific local safety codes and engineering requirements.
Yes, all NJMM industrial steel steps are CE certified. We also adhere to ISO 9001 and have successfully declared high-tech enterprise status, reflecting our commitment to global safety standards.
In standard industrial environments, our hot-dip galvanization provides superior anti-corrosion protection that can last between 30 to 50 years with zero maintenance, depending on the atmospheric conditions.
Absolutely. We offer full engineering services, including detailed CAD drawings and structural analysis, to help project managers optimize their steel consumption and reduce overall costs.
