As Bangkok continues its rapid ascent as a global hub for the Eastern Economic Corridor (EEC), the demand for resilient, high-performance industrial flooring and stair tread systems has reached an all-time high. From the sprawling transit stations of the MRT Blue Line extensions to the massive industrial estates in Samut Prakan and Chonburi, stair treads are more than just functional steps—they are critical safety components engineered to withstand Bangkok’s unique tropical humidity and intense pedestrian loads.
In the heart of Bangkok, commercial developments such as One Bangkok and the Dusit Central Park project require architectural-grade stair treads that blend aesthetic precision with uncompromising safety. Our JT series provides serrated surfaces to prevent slips during the monsoon season, ensuring public safety in high-traffic transit hubs.
Founded in 1993, NJMM (Ningbo Jiulong Machinery Manufacturing Co., Ltd) has evolved into a global titan in the steel grating and stair tread industry. With 30 years of expertise, we are not just a supplier; we are an engineering partner for Bangkok's most ambitious structural projects.

NJMM operates two massive production bases in the East and North of China, housing cutting-edge robotic welding systems and digital laser cutting technologies. Our commitment to the Bangkok market is reflected in our localized engineering support, providing detailed CAD drawings and installation supervision for complex petrochemical and municipal projects.
We utilize low-carbon steel and high-strength aluminum alloys (6063-T6) specifically chosen for their weight-to-strength ratios, critical for Bangkok’s high-rise external maintenance platforms.
Our "Serrated S" technology provides a 30% increase in friction coefficient compared to traditional flat bar treads, specifically designed for oil and gas refinery stairs in Rayong.
Utilizing BIM (Building Information Modeling) integration, we produce treads that fit perfectly into pre-existing structural models, reducing on-site waste to nearly zero.
As the "Green Industry" movement gains momentum in Thailand, NJMM is pioneering Eco-Galvanizing processes that recycle waste acids and reduce carbon footprints. Our future roadmap includes the development of Graphene-enhanced coatings for extreme durability in chemical processing plants.
For global EPC (Engineering, Procurement, and Construction) companies managing projects in Bangkok, NJMM offers a seamless supply chain. We understand the nuances of Incoterms 2020, Thai customs regulations, and the specific documentation required for VAT exemptions under BOI (Board of Investment) promoted projects.
