In the contemporary industrial era, the demand for high-strength, low-maintenance structural components has surged. Grating platforms serve as the backbone for infrastructure in energy sectors, urban development, and large-scale manufacturing. As industries transition toward Industry 4.0, these platforms are no longer just static walking surfaces; they are integrated components of smart factories, designed using advanced BIM (Building Information Modeling) to ensure seamless integration with complex piping and electrical systems.
Globally, the steel grating market is being driven by the expansion of petrochemical refineries in the Middle East, offshore wind farms in Europe, and the massive logistics hub constructions across North America. The shift towards sustainable materials has also prioritized Hot-Dip Galvanized (HDG) steel, known for its extreme longevity and 100% recyclability, aligning with global ESG targets.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM), founded in 1993, is a global leader in the steel grating industry. With two major production bases in China, we leverage three decades of experience to deliver custom engineering solutions. Our facility integrates scientific research, digital design, and robotic precision manufacturing.
We are not just a manufacturer; we are industry standard-setters. NJMM participated in drafting the YB/T4001-2019 steel grating standard. Our products carry international weight with ISO9001:2015, ISO45001:2018, ISO14001:2015, CE, and GHOST certifications.
Operating as a "Green Factory" and recognized as a high-tech enterprise, NJMM provides full-lifecycle support—from initial design and structural analysis to installation guidance and localized after-sales support in over 50 countries.
In environments characterized by extreme corrosion and volatile substances, NJMM’s serrated steel grating provides essential anti-skid properties. Widely used in refineries and offshore drilling rigs, our platforms (JG255/30/100, JG325/30/100) ensure ventilation, light penetration, and explosion-proof safety. The hot-dip galvanization process provides a chemical barrier that extends product life to 30+ years in marine environments.
For port terminals and mining facilities, the requirement is high load-bearing capacity. Our G505/30/100 to JG1008/30/100 series are engineered to withstand heavy machinery traffic while preventing the accumulation of snow, water, and debris, significantly reducing maintenance overhead.
Modern architectural projects use NJMM grating for aesthetic ceilings, ventilation screens, and high-strength stair steps. The clean, neat appearance of forge-welded bars offers a modern industrial look that complements contemporary building materials.
NJMM is committed to an innovation-driven future. Our roadmap for 2025-2030 includes:
Integrating AI algorithms to optimize the weight-to-strength ratio of grating platforms, reducing steel consumption by up to 15% without compromising safety.
Expansion of our 6 sets of automatic banding robots and 12 auto-welding lines to achieve zero-defect production cycles.
Pioneering the "Green Factory" concept by utilizing solar energy for production and recycled steel, helping our clients meet their Scope 3 emission targets.
Safety is non-negotiable. NJMM ensures that every platform delivered meets localized building codes across Europe (CE), North America (ANSI/NAAMM), and Asia (YB/T). We are proud to partner with global engineering giants.
A: Forge-welding uses heat and high pressure to fuse the cross bars and bearing bars together at every intersection. This creates a single-piece permanent structure with a high strength-to-weight ratio, ensuring zero gaps where corrosion could start.
A: Plain grating is ideal for standard pedestrian walkways and industrial floors. However, for environments where oils, chemicals, or moisture are present—such as oil rigs or food processing plants—serrated grating is mandatory to prevent slips and accidents.
A: HDG involves submerging the entire grating in molten zinc, creating a metallurgical bond. This provides complete coverage (including the insides of hollow sections) and offers superior cathodic protection, whereas cold galvanizing is simply a zinc-rich paint that can flake off.
A: Yes. We operate two sets of specialized fabrication platforms for irregular grating. We use digital tailoring to match your specific engineering drawings, ensuring easy site installation without the need for on-site cutting or welding.
