Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) was founded in 1993, is mainly engaged in the design and manufacturing of steel grating, railings, platforms and other light steel structures. It is a modern comprehensive enterprise integrating scientific research and design, machinery manufacturing and engineering construction. We currently have 2 production bases in the East and North of China, there are 12 steel grating auto welding product lines, as well as complete auxiliary processing equipment and testing facilities, like robots welding, laser cutting, digital control panel tailoring etc. Our annual output of steel gratings and allied products, including trench covers, stair treads, stanchions, handrails, fences, is over 50,000 metric tons.
NJMM offers engineering service and support, including the design and installation of the grating solutions and the provision of detailed drawings if required. NJMM is committed to a continuous process to enhance customer service through product quality and delivery. NJMM had got the ISO9001 Quality System Certificate, CE certificate, GHOST certificate and other international certificates. We believe our products are your best choice.

CE Certification is not just a label; it is a declaration that the product complies with the essential health and safety requirements of European directives. For steel stair tread pans, this primarily involves EN 1090-1 (Execution of steel structures) and EN 1090-2. As a leading manufacturer, NJMM ensures that every stair tread pan undergoes rigorous Factory Production Control (FPC), ensuring weld quality, material traceability, and load-bearing capacity performance.
Our products meet Eurocode standards for slip resistance and deflection limits under heavy industrial loads.
Utilization of 6-axis welding robots to ensure 100% penetration and aesthetic consistency across all joints.
Sourced from Tier-1 steel mills with mill test certificates (MTC) provided for every batch of Q235 or S275JR steel.
Procuring industrial components from China requires more than just low costs; it requires Local Regulatory Alignment. NJMM provides specific documentation for different regions:
Our location in Ningbo, one of the world's largest port cities, offers unparalleled logistical advantages. However, the true "Information Gain" for procurement officers lies in our Integrated Manufacturing Ecosystem. Unlike smaller workshops, NJMM controls the entire process: from raw material slitting and forging to pressure welding and automated galvanizing. This vertical integration reduces lead times by 30% and eliminates "middleman" quality risks.
The steel industry is moving towards "Green Steel" and carbon footprint tracking. NJMM is proud to be recognized as a Green Factory (2021). We utilize energy-efficient galvanizing furnaces and recycled steel scraps, helping our global partners meet their ESG (Environmental, Social, and Governance) targets.
High corrosion resistance and non-slip serrated designs for oil rigs and refinery walkways.
Heavy-duty load bearing treads for boiler rooms and turbine maintenance platforms.
Impact-resistant stair pans designed to handle ore dust and heavy vibration environments.
Our partners include top-tier EPC contractors and industrial giants worldwide.
