Frequently Asked Questions (FAQ)

What are the primary advantages of sourcing from NJMM?
NJMM offers a combination of 30 years of expertise, a massive 50,000-ton annual capacity, and full international certification (CE, ISO, GHOST). We provide end-to-end service from design to installation support.
Which stainless steel grades do you provide for gratings?
We primarily manufacture in SS304 and SS316L. SS304 is ideal for general industrial use, while SS316L offers superior resistance to pitting and corrosion in marine and high-chloride environments.
Can you handle custom shapes and irregular dimensions?
Yes, we have two dedicated irregular grating fabrication platforms and use laser tailoring to create gratings that fit perfectly around pipes, columns, and equipment based on your CAD drawings.
How do you ensure the quality of the welding?
Our 12 automatic pressure welding lines use high-voltage resistance welding, which fuses the load-bearing bars and cross-bars into a single, homogeneous structure, ensuring maximum strength compared to manual welding.
What is the typical lead time for international orders?
Depending on the order volume and customization level, standard products typically ship within 15-25 days. Our proximity to Ningbo port ensures rapid transit to global destinations.
