In the modern era of mega-infrastructure, the demand for high-quality walkway grating standards has shifted from simple utility to complex regulatory compliance. As urban centers and industrial zones expand in regions like the Middle East, Southeast Asia, and South America, the integration of steel grating is no longer just about flooring; it's about life-cycle cost reduction and personnel safety.
NJMM (Ningbo Jiulong Machinery Manufacturing Co., Ltd) serves as a critical node in the global supply chain, addressing the procurement needs of petrochemical plants, offshore platforms, and large-scale mining operations. We provide solutions that balance ventilation, load-bearing capacity, and corrosion resistance across diverse climates.
The transition toward Industry 4.0 has led NJMM to implement 12 automatic welding lines and robotic assembly. Our roadmap includes AI-driven quality inspection and carbon-neutral manufacturing processes, aligning with global "Green Factory" initiatives and ISO 14001:2015 environmental standards.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) is a modern comprehensive enterprise integrating scientific research, design, and machinery manufacturing. With an annual output exceeding 50,000 metric tons, we are the cornerstone of steel grating innovation in China.
NJMM markets its products mainly to South America, Europe, Oceania, Africa, West Asia, and the Middle East. Our "Longta" brand is synonymous with quality in renowned projects globally.
We hold ISO9001:2015, ISO45001:2018, ISO14001:2015, CE, and GHOST certificates. We actively participated in drafting the YB/T4001-2019 national steel grating standard.
Beyond manufacturing, we offer full engineering design services, providing detailed drawings and installation support to ensure our gratings meet project-specific requirements.
When procurement managers for global enterprises source walkway gratings, they focus on three core pillars: Reliability, Compliance, and Longevity.
NJMM’s products are recommended for high-load areas like port terminals (JG705/30/100) and general industrial walkways (JG255/30/100), ensuring that every specification meets the localized needs of the project site.
Ventilation and explosion-proof properties are paramount. Our JG series gratings are standard for refineries and textile chemical plants.
Utilizing high-strength materials like G505/30/100 to withstand heavy impact and saline corrosion in shipbuilding and offshore engineering.
Ditch covers and stair treads JT1-JT8 for airports, gardens, and urban parking lots, emphasizing aesthetic integration and fast installation.
We understand that a "standard" in Europe (CE) differs from requirements in Russia (GHOST) or the US (ASTM). NJMM provides localized engineering drawings that adhere to regional building codes, ensuring seamless approval processes for EPC contractors.
With production bases in both East and North China, NJMM optimizes shipping routes to major global ports. Our export volume exceeds 20,000 tons annually, backed by a robust tracking system for international delivery.
