In the contemporary industrial era, the demand for CE Certified Galvanised Steel Stair Treads has transitioned from simple utilitarian needs to complex engineering requirements. Across the globe—from the offshore oil rigs in the North Sea to the massive desalination plants in the Middle East—stair treads serve as the critical interface between human safety and structural performance.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM), established in 1993, has stood at the forefront of this evolution. With nearly three decades of experience, we recognize that stair treads are not merely steel bars welded together; they are precision-engineered safety components that must withstand corrosive environments, heavy dynamic loads, and extreme temperature fluctuations.

Years of Industry Expertise
As a leading manufacturer and factory, NJMM is pioneering the integration of AI-driven robotics and digital twin technology in the fabrication of steel gratings. Our technical roadmap focuses on three pillars: Load-Bearing Optimization, Metallurgical Advancement, and Sustainable Production.
We utilize 6 sets of automatic banding robots and 2 sets of irregular grating fabrication platforms. This ensures that every weld point on our stair treads meets the rigorous standards of ISO9001 and CE certification, minimizing human error and maximizing structural uniformity.
Our hot-dip galvanizing process follows strict environmental protocols while ensuring a zinc coating thickness that exceeds industry standards (YB/T4001). This provides a protective barrier that is chemically bonded to the steel, offering self-healing properties against scratches and abrasions.
Recognized as a "Green Factory" in 2021, NJMM is committed to reducing the carbon footprint of steel production. By optimizing raw material usage and employing energy-efficient laser cutting, we provide products that help our clients meet their ESG (Environmental, Social, and Governance) goals.
The global supply chain has faced unprecedented challenges in recent years. However, NJMM's strategic location in Ningbo—home to one of the world's busiest ports—combined with our vertical integration, ensures unmatched supply chain resilience. We don't just manufacture; we manage the entire lifecycle from design to global logistics.
Where explosion-proof and anti-skid performance is non-negotiable. Recommended: JG325/30/100 series.
Designed to withstand saltwater corrosion and high windage resistance. Used in platforms and walkways.
Heavy-duty loading capacity for heavy machinery areas and ventilation screens for underground operations.
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.
NJMM offers engineering service and support, including the design and installation of the grating solutions and the provision of detailed drawings if required. NJMM had got the ISO9001 Quality System Certificate, CE certificate, GHOST certificate and other international certificates.
Our commitment to quality is validated by ISO9001:2015, ISO45001:2018, and ISO14001:2015. NJMM even participated in drafting and revising the national steel grating standard YB/T4001 in 2019. This level of industry authority is why our products are trusted by partners worldwide, from South America to Europe and Oceania.
