As Qatar moves towards its National Vision 2030, the demand for high-performance industrial flooring and structural components has reached an all-time high. Doha, serving as the commercial heartbeat of the region, requires steel solutions that can withstand the unique challenges of the Gulf climate—high salinity, extreme thermal fluctuations, and intensive industrial usage.
Today's Doha market is no longer just about oil and gas. With massive investments in the Hamad Port, Lusail City, and expanded desalination plants, steel grating has become a fundamental "backbone" of urban infrastructure. In Qatar, the emphasis is on E-E-A-T compliant suppliers who can offer longevity. Products must meet stringent ASTM and BS standards to combat the corrosive nature of the Arabian Gulf’s coastal air.
Globally, the steel grating industry is shifting toward "Smart Manufacturing." Large-scale procurement now focuses on weight-to-strength ratios and lifecycle costs. NJMM leads this trend by providing hot-dip galvanized finishes that offer 20+ years of maintenance-free service, directly addressing the global industry's need for sustainable and durable construction materials.
Ningbo Jiulong Machinery Manufacturing Co., Ltd (NJMM) was founded in 1993 and has evolved into a global leader in the steel grating sector. As a modern comprehensive enterprise, we integrate scientific research, design, and precision machinery manufacturing.
With 12 state-of-the-art auto welding production lines and advanced robot welding systems, we ensure that every square meter of grating sent to Doha meets international quality benchmarks. Our annual output exceeds 50,000 metric tons, supporting iconic projects worldwide.

Our self-developed automatic pressure welding lines ensure consistent quality that manual welding cannot match. This efficiency translates to competitive pricing and rapid lead times for large Qatari tenders.
Located near major ports in East China, NJMM offers seamless shipping to Hamad Port, ensuring that project timelines in Doha are met without delay.
Our Hot-Dip Galvanizing process complies with ISO 1461, providing a thick, protective zinc layer essential for the humid, saline environment of Doha's petrochemical and offshore sites.
NJMM is a certified leader with ISO9001:2015, ISO45001:2018, and CE Certification. We are the preferred supplier for Fortune 500 industrial giants.
Our products are manufactured according to YB/T4001.1-2007 (China), ANSI/NAAMM (USA), and BS4592 (UK) standards. For Doha, we specifically recommend hot-dip galvanizing to ASTM A123 to ensure maximum corrosion resistance.
We utilize 12 automatic pressure welding lines and robotic assembly to ensure precise spacing and weld integrity. Each batch undergoes rigorous testing, and we provide CE and ISO certificates with every shipment.
Due to our high annual capacity of 50,000 tons, we can process large orders quickly. Standard production takes 2-3 weeks, with sea freight to Hamad Port taking approximately 20-30 days.
Yes, we offer full engineering support, including detailed shop drawings (AutoCAD/BIM) and customized fabrication for irregular platform shapes and specific load-bearing requirements.
