In the modern architectural and industrial landscape, Steel Tread Mesh has transcended its traditional role as a simple walkway material. Today, it serves as a critical component in structural safety, ventilation engineering, and sustainable urban design. As a premier Wholesale Steel Tread Mesh Manufacturer & Factory, Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) leads this evolution by merging 30 years of metallurgical expertise with cutting-edge AI-driven manufacturing processes.
Steel Tread Mesh, often referred to as bar grating or stair tread, is engineered to provide maximum strength-to-weight ratios. Unlike solid steel plates, the mesh design allows for the free passage of light, air, and liquids—essential in environments like petrochemical refineries, offshore oil rigs, and mining facilities where gas accumulation or fluid spillages pose significant hazards. Our factory focuses on "Information Gain" in production, utilizing data from stress-test simulations to optimize the cross-sectional area of our bearing bars, ensuring 100% compliance with international safety codes such as YB/T4001.1-2007 and ISO 14122.
NJMM controls the entire supply chain, from raw material carbon steel selection to the final hot-dip galvanizing process, ensuring consistency that fragmented suppliers cannot match.
Our 12 self-developed automatic pressure welding equipment lines and 6 sets of automatic banding robots minimize human error, providing perfectly aligned mesh every time.
Located in Ningbo, one of the world's largest ports, we provide unmatched shipping efficiency to Europe, South America, and the Middle East, reducing lead times by up to 25%.
The global demand for Wholesale Steel Tread Mesh is shifting towards intelligent, modular, and green solutions. We have identified three macro-trends that define the current landscape:
Our solutions for the Petrochemical and Mining industries (using JG505/30/100 or JG1008/30/100 specs) are specifically designed to meet these trends, offering a lifespan that exceeds 30 years even in harsh marine environments.
Serrated steel grating for anti-slip performance on wet oil rigs and vessel gangways. High salinity resistance is key.
Aesthetic ceiling mesh and high-load trench covers for subways and airports, balancing design with structural integrity.
Ventilated platform walkways in thermal and nuclear plants that facilitate heat dissipation and safety inspections.
Heavy-duty rack shelving made of forge-welded mesh to maximize fire sprinkler penetration and airflow.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) was founded in 1993 and has grown into a modern comprehensive enterprise integrating scientific research, machinery manufacturing, and engineering construction. We currently operate two massive production bases in East and North China, housing 12 steel grating auto welding product lines.
Our "Longta" brand is synonymous with excellence in China and abroad. With an annual output exceeding 50,000 metric tons, we offer comprehensive services including detailed design drawings, robotic precision cutting, and professional installation support. Our commitment is reflected in our certifications: ISO9001:2015, ISO45001:2018, ISO14001:2015, and CE/GHOST standards.
Vision: To be the leader in the steel grating market and the preferred supplier for global infrastructure.
Mission: To provide top-quality products with global expertise and build a harmonious environment for employees.
We treat quality like life itself. Participating in the drafting of the YB/T4001 standard in 2019, NJMM has been recognized as a municipal engineering center and a "Green Factory."
