Heavy-duty industrial configurations certified under ISO 9001 and CE frameworks, customized to resist regional soil salinity and atmospheric conditions along the Gorgol River Valley.
Kaédi, serving as the commercial and administrative heart of Mauritania’s Gorgol Region, is characterized by its dynamic agricultural output near the Senegal River, municipal expansion, and transitional climatic pressures. Navigating infrastructure builds in Kaédi requires deep engineering insight because of the unique environmental conditions: high diurnal temperature variations, dry desert winds carrying abrasive particulate matter (Harmattan), and localized high relative humidity zones during the wet season.
Standard carbon steel components degrade rapidly in riparian settings under aggressive solar heat. Our steel gratings and industrial stair treads feature a highly protective hot-dip galvanized coating (zinc density conforming to BS EN ISO 1461), guaranteeing long-term corrosion resistance for Kaédi’s water treatment complexes, agricultural irrigation schemes, and municipal processing hubs.
Additionally, the rise of regional distribution routes and solar power developments around Southern Mauritania calls for heavy structural pathways that can withstand sand deposits without losing their anti-slip qualities. This is where our hot-galvanized serrated forge-welded steel grating systems prove invaluable, offering superior safety profiles for logistics platforms, access walkways, and multi-tier utility assemblies.
Ensuring compliance with rigorous international mechanical performance ratings to protect local investments in municipal and commercial facilities.
In international engineering pipelines, the choice of flooring and perimeter protection relies on mechanical load calculations. In global logistics hubs and riverine ports, metal floorings must offer high open-area percentages (typically 65% to 80%) to allow air circulation, fluid drainage, and light passage.
Our industrial-grade hot-dip galvanized steel systems offer significant advantages over solid checker plates or cast metals:
Founded in 1993, Ningbo Jiulong Machinery Manufacturing Co., Ltd has established itself as an international benchmark in designing and manufacturing high-caliber steel gratings, industrial stanchions, stair treads, and structural platforms.
With a production base covering over 45,000 square meters and a workshop area of 30,000 square meters, our operations run 12 advanced automatic pressure welding product lines. Our engineering practices integrate robotic welding, digital control panels, and automated laser cutters. This allows us to yield over 50,000 metric tons of steel structures annually, including 20,000 tons destined for critical export markets globally.
As draftsmen of the Chinese national steel grating standard YB/T4001.1-2019, our company has earned ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, alongside European CE markers and regional GOST quality documentation.
Customized dimensions, loading patterns, and material grades to meet demanding industrial project requirements.
| Steel Grating Designation | Bearing Bar Dimensions (Height x Thickness) | Bearing Bar Pitch (mm) | Cross Bar Pitch (mm) | Applicable Structural Scenarios |
|---|---|---|---|---|
| JG255/30/100 | 25 mm x 5 mm | 30 mm | 100 mm | Standard access walkways, light-duty platforms, utility steps |
| JG325/30/100 | 32 mm x 5 mm | 30 mm | 100 mm | Heavy pedestrian traffic areas, chemical pump skids, riverine docks |
| JG405/30/100 | 40 mm x 5 mm | 30 mm | 100 mm | High-load process structures, industrial storage areas, vehicle zones |
| JG505/30/100 | 50 mm x 5 mm | 30 mm | 100 mm | Primary logistics flooring, heavy plant equipment bases |
| JG705/30/100 | 70 mm x 5 mm | 30 mm | 100 mm | Drainage channels, civil ditch protection subject to heavy traffic |
Selecting the appropriate structural configuration requires analyzing both Uniformly Distributed Loads (UDL) and Concentrated Point Loads (CPL) based on clear support spans. For instance, JG325/30/100 grating achieves an allowable load capacity of over 40 kN/m² on a clear span of 1.0 meter. This performance complies with EN ISO 14122 safety and occupational health specifications.
How our industrial steel solutions integrate into municipal infrastructure, logistics, and resource processing projects in Southern Mauritania.
Agricultural irrigation schemes in Gorgol rely on robust water pumping networks. Standard structural materials exposed to continuous moisture decay quickly. Our specialized aluminum I-Bar and hot-dip galvanized steel gratings provide durable, rust-resistant flooring for pump intakes, maintenance walkways, and valve vaults.
Seasonal downpours in Kaédi demand rapid stormwater drainage to protect critical municipal infrastructure. Our heavy-duty trench grates and ditch covers feature high open areas, which prevent siltation and clogs while bearing traffic loads from transport vehicles.
As an administrative hub, Kaédi supports regional logistics fleets. Our industrial handrails and stair treads provide safe, slip-resistant access for material handling yards, loading docks, and mezzanine platforms.
The expansion of solar infrastructure in rural Mauritania requires secure, weather-resistant structural components. Our perimeter fencing, cable tray supports, and equipment enclosures protect electrical installations against high winds and Saharan sandstorms.
NJMM controls every phase of production, from raw steel coil inspection to final hot-dip galvanizing, ensuring reliable performance in harsh environments.
Our industrial steel structural solutions are selected by major engineering groups for critical construction projects worldwide.
Select from our complete range of certified stair treads, pipe handrails, and industrial metal platforms, engineered for long-term field stability.
Essential technical information for civil engineers, procurement officers, and construction managers specifying steel structures in West Africa.
Our products conform to major international galvanization standards, including BS EN ISO 1461, ASTM A123, and AS/NZS 4680. We target an average zinc coating thickness of over 85 microns. This thickness provides long-term barrier protection against atmospheric moisture and dry sand friction in Gorgol's arid climate.
Fine desert sand carried by the Harmattan winds can make metal surfaces slippery. Our serrated forge-welded gratings feature notch profiles along the bearing bars. This design ensures safe footing even with dry soil or river mud build-up, reducing slip hazards in industrial walkways.
Yes. NJMM provides custom design and manufacturing support. Our CAD engineering team generates shop drawings based on client dimensions. We produce custom stair treads (with bolt holes and non-slip nosing bars), structural platforms, and safety railings to meet specific project dimensions.
With 12 automated welding lines and a 50,000-ton annual capacity, we manage fabrication schedules efficiently. Completed orders are loaded into ocean containers at Ningbo Port and shipped to West African ports such as Nouakchott (Mauritania) or Dakar (Senegal). From there, land freight options transport the materials directly to sites in Kaédi.
Each shipment includes a complete quality assurance package: raw material mill test certificates (MTC), galvanizing thickness test reports, load test compliance sheets, CE certificates, packing lists, and commercial invoices to simplify customs clearance.
