New York is a unique theater for railing manufacturers. From the corrosive salt-mist environments of Long Island Sound to the heavy pedestrian loads of Times Square and the strictly regulated fire egress paths of Manhattan high-rises, the demand for high-performance railing systems has never been higher. As New York continues its massive infrastructure renewal—including the $10 billion JFK Terminal 6 redevelopment and the constant expansion of the MTA subway network—the role of the manufacturer shifts from being a mere vendor to a strategic engineering partner.
In the New York market, we see a fusion of "Form and Function." Commercial projects (like the Hudson Yards) demand aesthetic modularity, whereas Industrial projects (wastewater treatment plants in Staten Island or power plants in New Jersey) demand extreme durability through hot-dip galvanization (ASTM A123) and chemical resistance.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) was founded in 1993, is mainly engaged in the design and manufacturing of steel grating, railings, platforms and other light steel structures. It is a modern comprehensive enterprise integrating scientific research and design, machinery manufacturing and engineering construction.
We currently have 2 production bases in the East and North of China, featuring 12 steel grating auto welding product lines. Our annual output exceeds 50,000 metric tons, serving global giants in the petrochemical, logistics, and civil construction sectors.

Development of Nano-ceramic galvanized layers that provide 200% more corrosion resistance than traditional hot-dip methods, specifically designed for New York’s coastal humidity.
Transitioning from site-welded systems to "Plug-and-Play" modular railing units. This reduces NYC labor costs—some of the highest in the world—by up to 60%.
Utilizing 100% recyclable steel and low-VOC powder coating lines to assist New York developers in achieving higher LEED certifications for their buildings.
In an era of global uncertainty, NJMM leverages Industry 4.0 principles to ensure the New York market remains supplied. Our "Longta" brand represents precision engineering. With 6 sets of automatic banding robots and 2 sets of irregular grating fabrication platforms, we handle complex New York architectural designs that standard manufacturers refuse.
Heavy-duty G505/30/100 solutions for NYC Port Authority piers, designed to withstand saltwater abrasion and massive impact loads.
Non-conductive and anti-sparking railing configurations for the renewable energy transition projects across the Tri-State area.
ADA-compliant handrail systems and safety walkways for the MTA and New York Department of Transportation (NYDOT).
Sourcing from overseas can be daunting for New York developers due to compliance fears. NJMM bridges this gap by adhering to ASTM, ANSI, and NAAMM standards. Our products carry CE certification and ISO9001:2015 status, ensuring that when our railings land at the Port of New York and New Jersey, they are ready for immediate inspection and installation.
New York City Building Code requires railings to be at least 42 inches high for most commercial and residential uses, with a maximum 4-inch gap between balusters. They must also support significant lateral and vertical loads as per the NYC Department of Buildings (DOB).
NJMM offers high-volume production, Grade 4.0 automation, and rigorous testing that meets American ASTM standards, providing a cost-to-quality ratio that local US manufacturers often cannot match, even when including shipping costs.
Yes, NJMM offers comprehensive engineering services, including detailed CAD drawings and structural calculations, to assist our clients in obtaining the necessary approvals from local NYC building departments.
We use high-grade hot-dip galvanization (per ASTM A123) and offer optional multi-layer powder coatings. This is essential for New York projects near the water or where road salt is used heavily during winter.
