Engineered for high-durability in Andean mining and Pacific coastal environments.
Peru is currently undergoing a massive industrial transformation. From the expansion of the Chancay Port to the continuous growth of the mining sectors in Arequipa, Cajamarca, and Ancash, the demand for high-integrity safety infrastructure has never been higher. As a specialized railing supplier and manufacturer, we recognize that the Peruvian market requires more than just standard products; it requires resilience against seismic activity and extreme atmospheric corrosion.
Operating in one of the world's most seismically active zones, Peruvian industrial facilities—especially in the processing plants of Antamina or Cerro Verde—demand steel railings and gratings that offer high structural elasticity and load-bearing capacity. Our ISO 9001:2015 certified manufacturing process ensures that every weld and joint can withstand the dynamic stresses inherent to the region.
Lima and the coastal port cities face a unique challenge: high humidity combined with saline air. Standard steel fails within months. Our solution? Hot-Dip Galvanization (ASTM A123). By providing a zinc coating thickness that exceeds industry standards, we ensure our railings and gratings serve the Peru market with a lifespan of 20+ years, even in the most aggressive maritime environments.
Founded in 1993, NJMM has evolved into a global leader in light steel structures. With two massive production bases and 12 automated pressure welding lines, we deliver over 50,000 metric tons of steel products annually. Our commitment to the Peruvian market is backed by global expertise and localized service support.

Auto-Welding Lines
Our 12 self-developed automatic welding lines ensure consistent quality that manual welding cannot match, reducing the risk of structural failure in critical Peruvian infrastructure.
Located near major ports, we offer streamlined logistics to Callao and Paita ports, ensuring that large-scale mining projects stay on schedule.
With CE, ISO, and GHOST certificates, our products meet the stringent safety requirements of international engineering firms operating in South America.
Heavy-duty JG705/30/100 gratings and stanchions designed for high-vibration environments in high-altitude Andean mines.
Serrated anti-slip gratings and hot-dip galvanized handrails for the Chancay Port megaproject, ensuring worker safety in wet conditions.
Aesthetic and functional railings for Lima's growing commercial hubs and metro infrastructure expansion.
The global procurement trend is shifting towards integrated solutions. Modern EPC (Engineering, Procurement, and Construction) companies serving the Peru market no longer just buy "pieces." They buy pre-engineered systems. NJMM provides:
