Industrial Safety Starts with Structural Integrity.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM), established in 1993, has emerged as a global vanguard in the engineering, design, and manufacturing of premium steel gratings and industrial stair treads. As a Stair Tread Supplier & Manufacturer with over three decades of empirical experience, we provide more than just hardware—we deliver critical safety infrastructure for the world's most demanding environments.
Our operational footprint encompasses two massive production bases in East and North China, powered by 12 automated steel grating pressure welding lines. This technological backbone allows us to achieve an annual output exceeding 50,000 metric tons, serving industries ranging from petrochemical offshore platforms to urban infrastructure projects.

NJMM is ISO9001:2015, ISO45001:2018, and ISO14001:2015 certified. Our products carry the CE mark, ensuring full compliance with European safety standards and global industrial requirements. We participated in drafting the YB/T4001 steel grating standard, positioning us as industry thought leaders.
We are transitioning into "Industry 4.0" with laser cutting, digital control panel tailoring, and 6-axis robotic welding. Our R&D focuses on "Green Galvanization" and high-tensile lightweight alloys to reduce carbon footprints while maintaining structural loading capacities.
Leveraging China's world-class logistics and raw material efficiency, NJMM provides unmatched price-to-performance ratios. Our "Just-In-Time" (JIT) delivery system ensures that even complex, custom-fabricated stair treads reach sites in South America, Europe, and the Middle East without delay.
Petrochemical & Offshore: In the corrosive environments of Southeast Asian oil refineries or North Sea offshore rigs, our Hot-Dip Galvanized (HDG) stair treads provide superior oxidation resistance. The serrated anti-slip surface is a critical requirement in these moisture-prone sectors.
Urban Mining & Refining: In Australia and South Africa, mining terminals utilize our heavy-duty JG1008/30/100 series for equipment protection and platform walkways. These treads are engineered to withstand extreme vibrations and heavy debris accumulation.
Commercial Architecture: Beyond heavy industry, the modern "Industrial Aesthetic" has led to increased demand in Europe and North America for our ceiling and ventilation screen gratings, combining functional load-bearing with architectural transparency.
Supply Chain Resilience: NJMM’s dual-base production strategy (East & North China) mitigates regional logistical risks. With 12 independent lines, we maintain production continuity even during peak demand cycles or raw material fluctuations.
Application: Platform walkways and stair steps in heavy industrial complexes.
As we look toward 2030, NJMM is committed to the development of "Eco-Structural Solutions." This includes the integration of recycled steel and the implementation of solar-powered production facilities. Our goal is to remain the preferred global Stair Tread Manufacturer by balancing industrial strength with environmental responsibility, ensuring that every step taken on our treads is a step towards a safer and greener future.
