Galvanised open mesh flooring has transitioned from a basic industrial utility to a high-performance structural element. Modern demands focus on strength-to-weight ratios and corrosion resistance in extreme environments like offshore wind farms and chemical processing plants.
The shift towards "Green Steel" and sustainable galvanizing processes is driving procurement. Manufacturers like NJMM are leading the way with environmentally compliant waste disposal and energy-efficient forge-welding product lines.
Global regulations (ISO, CE, and national standards like YB/T4001) now mandate stricter slip-resistance and load-bearing certifications. Serrated designs and precision robot welding have become the industry gold standard.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM), founded in 1993, is a global leader in the design and manufacturing of steel grating, railings, and light steel structures. We operate as a modern comprehensive enterprise integrating scientific research, machinery manufacturing, and engineering construction.
With 12 steel grating auto welding product lines and advanced auxiliary equipment including welding robots and laser cutting systems, our annual output exceeds 50,000 metric tons. Our commitment to ISO9001, CE, and GHOST certifications ensures reliability at every stage of the supply chain.
The "China Factory 4.0" model, epitomized by NJMM, provides unmatched supply chain resilience. By integrating self-developed automatic pressure welding equipment with 6 sets of automatic banding robots, we ensure precision that exceeds manual fabrication while significantly reducing lead times.
Fast delivery to Europe, South America, and the Middle East through optimized logistics.
ISO9001:2015 and ISO14001:2015 certified workflows for total quality assurance.
Automation reduces material waste and labor costs, passing savings to global procurers.
From JG255 to JG1008, we offer tailored solutions for specific loading requirements.
Highly corrosion-resistant galvanised flooring for walkways and platforms. Recommended: JG325/30/100 for optimal ventilation and safety.
Strong loading capacity for port terminals and naval engineering. Using steel gratings saves on weight and supporting structure costs.
Ditch covers, stair treads, and ventilation screens for parking lots, sewage plants, and airports with high aesthetic and functional value.
Ventilation: Superior light and heat dissipation for safe plant environments.
Anti-Slip: Serrated designs prevent accidents in oily or wet conditions.
Anti-Corrosive: Hot-dip galvanization provides decades of service life.
Economic: Low maintenance and fast installation using specialized clips.
Loading: Engineered for high-altitude windage resistance and heavy machinery.
Hot-dip galvanizing creates a metallurgical bond that provides superior cathodic protection against rust, especially in harsh chemical or coastal environments, significantly extending the lifecycle compared to paint.
We utilize 12 automatic pressure welding lines and digital quality control panels to ensure every panel meets ISO and CE specifications. Our annual 50,000-ton capacity allows us to maintain consistency across massive projects.
Yes, our engineering team offers full support including detailed solution design, installation drawings, and technical consultation for complex structural requirements.
These designations refer to different mounting and nosing styles. For example, JT1 is for welded installation without nosing, while others include bolted end plates and anti-slip nosing for enhanced safety.
