In the contemporary industrial landscape, Open Grid Steel Flooring has evolved from a simple structural component to a sophisticated engineering solution critical for safety, efficiency, and architectural integrity. As a leading China-based manufacturer, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) stands at the intersection of traditional craftsmanship and digital manufacturing innovation.
Modern industrial facilities—ranging from offshore oil rigs to high-tech automated warehouses—require flooring systems that can withstand extreme corrosive environments while ensuring operative safety. The "Open Grid" design is inherently superior due to its self-cleaning properties, allowing water, debris, and snow to pass through, thereby reducing maintenance cycles and enhancing anti-slip performance.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM), founded in 1993, is a titan in the light steel structure industry. Integrating scientific research, precision design, and large-scale manufacturing, NJMM has become the benchmark for steel grating excellence in East and North China. With two massive production bases and 12 automated welding lines, we deliver over 50,000 metric tons of steel products annually.
Corrosion-resistant galvanized grating for oil rigs and refineries. NJMM's JG405/30/100 series offers unparalleled stability in high-moisture, saline environments.
Ditch covers, ceiling panels, and ventilation screens for airports, subways, and commercial hubs. Aesthetic appeal meets structural rigidity.
Platforms for wind turbines and solar plants where lightweight, high-load capacity flooring is essential for structural longevity.
Our products are widely applied in South America, Europe, Oceania, Africa, and the Middle East. We don't just supply products; we provide Localization Support & Compliance Guarantees. Whether it’s the CE certification for the European market, the GHOST certificate for Eurasia, or ISO9001 quality management, NJMM ensures every square meter of flooring meets local safety and regulatory codes.
The future of China Open Grid Steel Flooring lies in "Smart Manufacturing." NJMM is currently investing in Robotic Banding and AI-controlled laser cutting to achieve zero-tolerance precision.
12 Auto-welding lines, ISO45001 certification, and Green Factory status. Focus on mass customization and export efficiency.
Integration of IoT in production tracking and the adoption of ultra-high-strength alloy steels for weight reduction.
Carbon-neutral manufacturing processes and 100% recyclable flooring systems to support global ESG initiatives.
With 450,000 SQM and 12 self-developed automatic lines, our capacity exceeds 50,000 tons annually. We ensure excellence in every weld.
NJMM holds ISO9001:2015, ISO45001:2018, and CE certifications. We are pioneers who participated in drafting the YB/T4001 steel grating standards.
Our service network spans the globe, providing "Longta" brand steel grating to renowned projects worldwide with unmatched lead times.
NJMM’s product range covers diverse loading requirements and environmental conditions:
The grid structure ensures light and heat dissipation, reducing wind resistance in high-altitude projects.
Hot-dip galvanization provides decades of anti-corrosion protection, significantly lowering total cost of ownership.
Serrated types offer high-performance anti-slip properties, essential for wet or oily operative environments.
