Top-tier components ready for the Gulf Coast's most demanding environments.
Houston, Texas, recognized globally as the "Energy Capital of the World," hosts a dense concentration of petrochemical complexes, oil refineries, and maritime facilities. The Port of Houston, one of the world's busiest ports, creates a unique environmental challenge: high humidity, saline air, and intense industrial activity. In this context, "Hot Products" such as heavy-duty steel gratings and industrial stair treads are not merely components; they are critical safety infrastructure.
Current industrial trends in the Houston market indicate a significant shift toward resilient infrastructure. As facilities age and new investments in Carbon Capture and Sequestration (CCS) and Hydrogen production expand across the Houston Ship Channel, the demand for high-specification galvanized steel has reached record levels. Our engineering team at NJMM has analyzed these localized needs to provide products that meet and exceed ASTM A123 standards for galvanization, ensuring 20+ years of maintenance-free service in corrosive Gulf Coast environments.
The technical evolution of steel grating has moved from manual fabrication to High-Frequency Forge Welding and Robotic Precision Cutting. For the Houston market, we have implemented a specific technical roadmap focusing on three pillars:
Furthermore, our supply chain resilience is anchored by our dual production bases in China. By leveraging the logistics efficiency of the Ningbo-Zhoushan port—the world's largest by cargo tonnage—we ensure a seamless bridge to the Houston port system, offering lead times that compete with domestic fabricators while providing superior manufacturing scale.
Founded in 1993, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) is a pioneer in the design and manufacturing of steel gratings, railings, and light steel structures. We are not just a factory; we are a modern comprehensive enterprise integrating scientific research, machinery manufacturing, and global logistics.
State-of-the-art production base with 12 automatic pressure welding lines.
ISO9001:2015, CE, and GHOST certifications ensure every bar meets global standards.
Over 20,000 tons exported annually to South America, Europe, Oceania, and the USA.
Full design services including detailed layout drawings and installation guidance.
Widely used in the petrochemical and light chemical industries of the Houston Ship Channel. Recommended: JG255/30/100, JG325/30/100.
Designed for port terminals, mining, and offshore engineering. Capable of supporting heavy machinery and high-traffic loads.
Modern architectural applications in Houston commercial buildings, providing both aesthetic appeal and airflow efficiency.
Hot-dip galvanized pipe railings for harsh marine environments, ensuring OSHA compliance for personnel safety.
As the industrial sector moves toward "Net Zero," NJMM is leading the way in Green Manufacturing. In 2021, we were recognized as a "Green Factory," optimizing our energy consumption and implementing advanced recycling systems for our galvanization process. For the Houston market, which is increasingly focused on ESG (Environmental, Social, and Governance) criteria, partnering with a green-certified supplier provides a significant competitive edge.
Our Technical Roadmap includes the development of Composite Steel Solutions—hybrid structures that combine the strength of traditional steel with the corrosion resistance of advanced coatings. This will be vital for the next generation of Houston's offshore wind and maritime infrastructure.
Retaining original product specifications with localized application profiles.
All our gratings and stair treads are manufactured to meet or exceed ASTM A123 (Standard Specification for Zinc Coatings) and OSHA safety guidelines. We provide material test reports (MTRs) and galvanization certificates with every shipment to the Texas market.
By leveraging our 12 automatic welding lines, we can produce over 50,000 tons annually. Typical production time for standard orders is 2-3 weeks, with sea freight to the Port of Houston taking approximately 4-6 weeks. We also offer expedited air-freight for critical replacement parts.
Yes. Our in-house engineering team uses advanced CAD and BIM software to provide detailed shop drawings. We work closely with Houston-based EPC (Engineering, Procurement, and Construction) firms to ensure 100% fit-up accuracy before the product leaves our factory.
Forge-welding uses high-temperature and high-pressure to fuse the cross bars and bearing bars into a single, homogenous unit. This eliminates the internal stresses and potential rust points found in manual fillet welds, which is crucial for the high-vibration and corrosive environments of Texas refineries.
