Engineered for the rigorous demands of Nagoya's Port and Chubu's manufacturing facilities.
Nagoya, the heart of the Greater Nagoya Initiative and the capital of Aichi Prefecture, stands as Japan's premier manufacturing powerhouse. Home to the world's leading automotive giants and the Port of Nagoya—Japan's largest and busiest port—the region demands infrastructure components that offer unparalleled durability and safety.
In the Chubu industrial corridor, stair treads are more than just functional components; they are critical safety assets in automotive assembly lines, chemical refineries, and complex logistics warehouses. Our galvanized steel stair treads are specifically engineered to meet the high-seismic standards and corrosive environments typical of Japanese coastal industrial zones.

Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) was founded in 1993 and has evolved into a global leader in the design and manufacturing of steel grating, railings, and light steel structures. Our mission is to provide the top quality products & services with global expertise, particularly focusing on the precise needs of the Japanese market.
With a 450,000 square meter production footprint, NJMM integrates advanced robotics and laser cutting technologies to ensure every stair tread delivered to Nagoya meets the strictest tolerances. We are not just a supplier; we are an engineering partner that understands the nuances of Japanese JIS standards and EHS (Environment, Health, and Safety) requirements.
By eliminating middle-market distributors, Nagoya procurement officers can access factory-direct pricing without compromising on quality, saving up to 30% on large-scale infrastructure projects.
Our production lines are calibrated to meet both international CE and specific Japanese Industrial Standards (JIS). Each batch undergoes rigorous load testing and galvanization thickness verification.
Strategically located near Ningbo Port, we offer the fastest shipping routes to the Port of Nagoya, ensuring your project timelines remain on schedule with predictable lead times.
Nagoya's unique architectural and industrial layouts often require non-standard shapes. Our in-house CAD team provides detailed drawings and customized fabrication for complex platform designs.
Petrochemical Plants
Corrosion-resistant walkways for coastal refineries.
Automotive Assembly
Anti-slip steps for high-traffic production lines.
Nagoya Port Logistics
Heavy-duty ditch covers and mezzanine flooring.
Public Infrastructure
Modern, clean aesthetics for urban Nagoya developments.
Hot-dip galvanized carbon steel is the industry standard due to its balance of cost and durability. However, for specialized environments like food processing in Aichi, stainless steel or aluminum I-bar gratings are preferred for their superior hygiene and weight-to-strength ratios.
We utilize deeper bearing bars and reinforced welding techniques (forge welding) that provide better structural integrity during lateral vibrations, a critical factor for Chubu region's seismic safety requirements.
Yes. We offer serrated surfaces combined with checker plate nosing or abrasive strip nosing to meet the highest safety classifications for wet and oily environments typical in Nagoya's heavy industry.
Typical fabrication takes 7-14 days depending on volume, with a transit time of approximately 3-5 days from Ningbo Port to Nagoya Port. This makes NJMM as fast as many domestic Japanese suppliers.
