High-precision steel grating and stair tread systems engineered for durability.
In the modern industrial landscape, Platform Grating is no longer just a structural component; it is a critical safety and efficiency asset. As a leading China Platform Grating Manufacturer, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) has observed a shift from basic functional flooring to high-performance, intelligent structural solutions. Global enterprises now demand products that withstand extreme environments—from offshore oil rigs to high-temperature chemical refineries—while maintaining strict compliance with international safety standards.
Why do global EPC (Engineering, Procurement, and Construction) companies turn to China for platform grating? The advantage lies in the integration of the supply chain. With two major production bases in East and North China, NJMM leverages proximity to premium raw material sources and a highly skilled engineering workforce. Our 12 automated pressure welding lines ensure a consistency that manual fabrication cannot match, producing over 50,000 metric tons annually. This scale allows for rapid turnaround times, crucial for large-scale infrastructure projects where delays translate to millions in lost revenue.

NJMM (Ningbo Jiulong Machinery Manufacturing Co., Ltd), founded in 1993, embodies the core pillars of Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T). Our Experience spans three decades of evolving alongside the steel industry. Our Expertise is reflected in our participation in drafting the 2019 Chinese Steel Grating Standard (YB/T4001). We maintain Authoritativeness through international certifications including ISO9001:2015, ISO45001, and CE markings. Finally, our Trustworthiness is proven by our partnerships with global giants in the petrochemical and shipbuilding sectors.
Founded in 1993, NJMM is a modern comprehensive enterprise integrating scientific research, design, manufacturing, and engineering construction. We specialize in steel grating, railings, platforms, and light steel structures. Our facilities include robots welding, laser cutting, and digital control panel tailoring to ensure precision in every millimeter.
Capacity & Infrastructure: 2 production bases covering 450,000 m², with 30,000 m² of workshop area. We produce over 50,000 tons of trench covers, stair treads, stanchions, and fences annually, with 20,000+ tons dedicated to the export market.
We provide full compliance with ASTM (USA), BS (UK), and AS (Australia) standards. Our hot-dip galvanization process meets ISO 1461 requirements, ensuring decades of corrosion resistance in maritime and industrial environments.
NJMM offers detailed engineering shop drawings (BIM-compatible) to fit local architectural requirements. We support local installers with modular designs that require zero on-site cutting or welding.
Recognized as a "Green Factory" in 2021, we prioritize environmental health and safety, reducing carbon footprints through energy-efficient robotic welding and sustainable waste management.
