The global industrial landscape is undergoing a radical shift toward sustainable infrastructure and enhanced occupational safety. As of 2024, the demand for Galvanised Walkway Grating has reached an all-time high, driven by the expansion of petrochemical plants, offshore oil rigs, and large-scale renewable energy projects. In regions like the Middle East and Southeast Asia, corrosive environments necessitate the use of premium hot-dip galvanized steel to ensure a service life exceeding 30 years.
With urbanization accelerating in Brazil and India, galvanized grating is the standard for urban drainage, subway ventilation, and public walkways due to its immense strength-to-weight ratio.
International safety protocols (OSHA, EN ISO 14122) now mandate non-slip serrated surfaces in high-moisture industrial zones, cementing grating as a critical safety component.
The steel industry is moving toward "Green Steel." Hot-dip galvanization is recognized as an eco-friendly coating due to its durability and 100% recyclability of the zinc-steel substrate.

Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) stands at the forefront of grating technology. Our manufacturing process integrates AI-driven precision and robotic automation to deliver products that exceed industry benchmarks.
Integration of strain sensors within walkway structures to monitor real-time load distribution and structural fatigue in mega-bridges.
Prefabricated platform modules (Grating + Railing + Stanchion) that reduce on-site labor by 60% and improve safety.
Development of hybrid coatings (Zinc + Epoxy) for extreme chemical environments where traditional galvanization faces acid-base challenges.
NJMM’s products are engineered for specific regional challenges:
NJMM provides more than just components; we offer Engineering Service and Support. From the initial design phase using 3D modeling to the final provision of detailed installation drawings, our approach ensures that every platform, walkway, and stair tread functions as a cohesive, safe unit.
Our commitment to quality is validated by international standards, including ISO9001:2015, ISO45001:2018, and CE certification. We don't just supply; we partner with global giants in the petrochemical, shipbuilding, and energy sectors to build the future.
Founded in 1993, Ningbo Jiulong Machinery Manufacturing Co., Ltd is a modern comprehensive enterprise integrating scientific research, design, manufacturing, and engineering. With two massive production bases in East and North China, we leverage 12 auto-welding lines to produce over 50,000 metric tons annually.
We own 6 sets of automatic banding robots and 2 sets of irregular grating fabrication platforms, ensuring every custom project meets exact specifications.
Our "Longta" brand is recognized across South America, Europe, Oceania, and the Middle East, participating in some of the world's most renowned engineering projects.
ISO9001, CE, GHOST, and a declared High-Tech Enterprise and Municipal Engineering Center status since 2020.
A: Hot-dip galvanization provides a metallurgical bond that protects the steel both physically and cathodically. Unlike paint, it does not peel and offers superior resistance to abrasion and corrosion, resulting in a much lower lifecycle cost.
A: Plain grating is ideal for most commercial and industrial walkways. Serrated grating features notches on the load bars, providing extra grip in environments prone to oil spills, ice, or wet conditions, significantly reducing slip hazards.
A: Every stair tread (JT1 through JT8) is manufactured to international standards. We use specialized robotic welding for the end plates and check all load-bearing welds to ensure they can withstand the specified point and UDL (Uniformly Distributed Load) requirements.
A: Yes. We have 2 dedicated irregular grating fabrication platforms. Our engineering team can work from your CAD drawings or provide detailed drawings to ensure a perfect fit around pipes, columns, and equipment.
