GNEE STEEL is pleased to announce the successful completion of production for its latest batch of high-strength NM400 screen mesh, a significant addition to the company's growing line of abrasion-resistant steel products.


The NM400 screen mesh, known for its exceptional hardness and durability, has been manufactured using advanced heat treatment processes and strict quality control measures. With a hardness level reaching approximately 400 HBW, this screen mesh is specifically engineered to withstand high-impact and high-wear environments, making it an ideal solution for heavy-duty screening applications in mining, quarrying, coal processing, and construction material production.
The completion of this NM400 screen mesh production run reflects GNEE STEEL's ongoing commitment to delivering superior wear-resistant solutions to global clients, Our NM400 screen mesh offers extended service life compared to standard mild steel screens, significantly reducing downtime and replacement frequency for end users.
Key features of the GNEE NM400 screen mesh include:
- Excellent resistance to abrasion and impact
- High tensile strength and structural integrity
- Consistent perforation accuracy for efficient screening
- Customizable hole shapes and sizes according to client requirements
The product has already passed internal factory tests, including hardness uniformity checks and perforation tolerance evaluations. GNEE STEEL is now ready to fulfill both domestic and export orders, offering flexible sizing and packaging options to meet diverse project needs.
GNEE STEEL continues to expand its wear-resistant steel portfolio, which includes NM400, NM450, NM500, and other specialized grades for industrial applications. With the addition of the NM400 screen mesh, the company further solidifies its position as a one-stop supplier for high-strength steel products.
