Read More →Founded in 1993, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) has established itself as an elite global powerhouse in the design, engineering, and mass fabrication of high-performance steel gratings, industrial railings, platforms, and allied light steel structural units. Over three decades of technology refinement, we have merged scientific research, digital manufacturing, and international structural execution into a seamless operational pipeline.
To serve the European market, particularly Hungary’s soaring industrial infrastructure, we operate two massive state-of-the-art production bases. Our facilities feature 12 automatic pressure-welding lines, robotic edge-banding cells, high-precision laser profiling equipment, and automated CNC panel tailoring units. With a robust annual capacity exceeding 50,000 metric tons, we provide reliable, certified structural components configured exactly to local project demands.
Our commitment to local regulations is backed by ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, alongside complete CE and GOST marking credentials. For projects in Hungary, we offer dedicated design support, providing fully detailed layout drawings and customized load ratings to simplify local planning approvals.
Addressing the architectural safety and mechanical performance requirements of Hungary's evolving high-tech manufacturing landscape.
Debrecen, Szeged, and Nyíregyháza are rapidly developing into leading hubs for EV battery manufacturing. These specialized cleanroom facilities demand heavy-duty, low-magnetic, and non-sparking walkways, often calling for high-grade Aluminum I-Bar Grating to maintain cleanroom integrity and operator safety.
With major automotive production centers in Győr, Kecskemét, and Debrecen, dynamic assembly lines rely heavily on high-precision overhead maintenance walkways. Our press-locked and forge-welded steel structures deliver optimal ventilation, high load capacity, and compatibility with complex suspended conveyor layouts.
Operating conditions in Hungarian chemical and municipal sewage treatment utilities present severe corrosion challenges. NJMM's hot-dip galvanized steel grating, processed in strict alignment with EN ISO 1461 standards, features a zinc coating of 85+ μm to ensure lasting rust protection and structural safety.

When implementing steel gratings in European civil engineering projects, compliance with regulatory codes is critical. NJMM ensures that every order shipped to Hungary is fully certified and tracked to meet the demands of both project managers and local inspectors:
Transitioning from traditional manufacturing to smart, automated, and sustainable steel grating production.
We utilize automated robotic welding stations to execute complex grating cutouts, radial curves, and edge bandings, achieving millimeter-level tolerances that ensure a perfect fit on-site.
By providing native CAD and BIM models, we integrate directly with structural designers in Hungary. This helps identify structural interference early, accelerating the design-to-delivery cycle.
NJMM is recognized as a Green Factory. We use energy-recovery induction systems on our welding lines and source raw steel with verified recycled content to lower product carbon footprints.
