In the modern industrial landscape, procurement departments for Fortune 500 energy and construction firms prioritize "Reliability Engineering." Stair treads are no longer simple components; they are critical safety assets. As a leading manufacturer, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) addresses the global demand for Hot-Dip Galvanized (HDG) and Stainless Steel solutions that withstand C5-M marine environments and high-traffic industrial corridors.
Our solutions span across the Petrochemical, Mining, and Infrastructure sectors. By integrating modular design with structural integrity, we reduce on-site labor costs by up to 30%. NJMM’s stair treads (JT1-JT8 series) are engineered to comply with YB/T4001, ISO 9001:2015, and CE standards, ensuring seamless integration into complex architectural frameworks like refinery walkways and offshore platforms.
The future of stair tread manufacturing lies in precision. NJMM utilizes 12 automated pressure welding product lines and 6-axis robotic banding systems. Our tech roadmap includes AI-driven quality inspection and digital twin modeling for irregular grating fabrications. This ensures that every weld point meets a zero-defect threshold, maximizing the load-to-weight ratio for our clients.
Founded in 1993, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) has emerged as a titan in the steel grating and light steel structure industry. We are not just manufacturers; we are designers and engineering consultants. Our two massive production bases in East and North China serve as the heartbeat of our operations, producing over 50,000 metric tons annually.
NJMM offers comprehensive engineering support, providing detailed CAD/BIM drawings and on-site installation guidance. Our commitment to the "Craftsman Spirit" is reflected in our ISO9001, CE, and GHOST certifications, positioning us as a preferred Tier-1 supplier for global infrastructure projects.
Resistant to salt-spray corrosion. Recommended: JG325/30/100 series with hot-dip galvanization for 20+ years of service life in maritime environments.
Applied in power plants, cement factories, and refineries. Our JT series provides high-ventilation, light-weight, and high-load capacity for complex piping platforms.
Heavy-duty solutions like JG1008/30/100 are designed to handle the impact and vibration loads of heavy machinery and conveyor walkways.
NJMM is a "Green Factory" awardee (2021). We prioritize low-carbon steel sourcing and eco-friendly galvanizing processes, meeting EU environmental directives.
| Feature | Standard Solution | NJMM Premium Advantage |
|---|---|---|
| Load Capacity | Generic grating limits | Robot-welded cross-bars for 25% higher tensile strength |
| Anti-Corrosion | Cold plating / Paint | Hot-Dip Galvanization (ISO 1461) + Passivation |
| Safety Feature | Flat surface | Serrated anti-slip design for greasy/icy environments |
| Installation | Welding on-site | Pre-fabricated JT series with bolt-down clips for rapid assembly |
We utilize automatic pressure welding which ensures deep fusion of the bearing bar and cross bar, unlike manual welding which can be inconsistent. This increases durability and safety.
Yes, we have 2 sets of dedicated irregular grating fabrication platforms and offer full CAD design support to ensure a perfect fit for complex geometries.
We have a service network covering South America, Europe, and the Middle East. Our logistics team handles sea freight documentation, ensuring compliance with local customs like CE or GHOST.
With an annual capacity of 50,000 tons and 12 production lines, we offer industry-leading turnaround times, often shipping within 15-30 days of design finalization.
