Advancing Infrastructure Resilience with China Factory 4.0: High-Performance Steel Grating & Industrial Flooring Solutions tailored for the Greater Paris Area.
Engineered for durability in the high-demand environments of the Île-de-France region.
Paris, often celebrated for its heritage, is currently undergoing a massive industrial transformation. The Grand Paris Express, one of Europe’s largest infrastructure projects, along with the redevelopment of the Seine-Nord Europe Canal, has catalyzed a surge in demand for high-strength, low-maintenance structural components. As a leading manufacturer, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) recognizes that the Paris market requires more than just commodities; it demands Information Gain—solutions that integrate safety, aesthetics, and carbon-conscious logistics.
From the industrial corridors of Saint-Denis to the high-tech logistics hubs near Charles de Gaulle Airport, the requirement for galvanized steel grating and railings has evolved. Modern Paris projects prioritize E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness). Our 30-year legacy in precision manufacturing ensures that every stair tread and trench cover meets the rigorous Eurocode standards and French building safety regulations (ERP - Établissements Recevant du Public).

In the post-pandemic era, supply chain resilience is the primary concern for global procurement officers. NJMM’s adoption of Industry 4.0 principles—featuring robot welding, laser cutting, and digital control panel tailoring—allows us to offer the Paris market a unique combination of efficiency and precision. By utilizing automated pressure welding equipment, we eliminate human error, ensuring consistent bond strength and visual uniformity, which is critical for architectural applications in the French capital.
Our commitment to a "Green Factory" philosophy aligns with the European Union’s decarbonization goals. Through optimized material usage and advanced hot-dip galvanizing processes, we reduce the lifecycle environmental impact of our products, providing a sustainable choice for French contractors focused on HQE (Haute Qualité Environnementale) certification.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) was founded in 1993 and is mainly engaged in the design and manufacturing of steel grating, railings, platforms, and other light steel structures. We operate as a modern comprehensive enterprise integrating scientific research, machinery manufacturing, and engineering construction.
With a service network spanning over 13 countries and regions, we have supplied renowned projects worldwide. Our "Longta" brand steel grating has become synonymous with quality in the petrochemical, light chemical, and shipbuilding industries. Our certifications include ISO9001:2015, ISO45001:2018, ISO14001:2015, and CE, ensuring full compliance with international safety and quality protocols.
Widely used in the industrial zones of Gennevilliers and Vitry-sur-Seine. Recommended for petrochemical and refinery platforms requiring superior ventilation and anti-skid properties.
Ideal for Paris Metro maintenance tunnels and RER station ventilation screens. Our serrated steel gratings provide maximum safety for commuters and maintenance staff.
Modern style aluminum grating used in La Défense business district commercial centers, providing a sleek aesthetic with heat dissipation benefits.
Applied in the Port de Paris logistics terminals, where high loading capacity (JG1008/30/100) is required for heavy equipment transit.
Yes, all NJMM products are CE certified and produced in compliance with ISO9001 quality systems. Our steel gratings are designed to meet Eurocode 3 standards for structural steel design, ensuring they are suitable for all major projects in Paris and the wider EU.
Leveraging our 12 automated production lines, we can fulfill large orders within 2-4 weeks. Shipping to Le Havre (the main gateway for Paris) typically takes 30-35 days, providing a total lead time that is often shorter than local European manufacturers during peak demand.
Absolutely. We have 2 sets of dedicated irregular grating fabrication platforms and use digital tailoring to ensure precision. We can work directly from your CAD or BIM files to produce gratings that fit complex Parisian building geometries perfectly.
Our hot-dip galvanizing process complies with GB/T 13912 and BS EN ISO 1461 standards. This provides a thick, metallurgical bond of zinc that protects the steel in even the most humid environments along the Seine or industrial zones.
Yes, we offer comprehensive engineering services, including the design of grating solutions, provision of detailed shop drawings, and technical support during the installation phase to ensure safety and efficiency.
By optimizing steel consumption and utilizing high-efficiency Chinese manufacturing, we offer a significant cost-per-square-meter advantage without compromising on quality. Additionally, our gratings require zero maintenance, reducing long-term OPEX for facility managers.
