Ashok Steel Industries operates one of Nepal’s most advanced integrated steel plants, combining modern manufacturing technology with stringent quality assurance practices. Every stage—from melting and casting to rolling and testing—is executed with precision, enabling us to deliver products that meet national and international standards. Our commitment to innovation, safety, and consistency has made Ashok Steel a trusted name for engineers, contractors, and industrial manufacturers across Nepal.
Our Manufacturing Process
Fully controlled processes for uniform strength, purity, and quality.
Step 1: Steel Melting Furnace
High-grade raw materials are melted in an energy-efficient furnace ensuring stable temperature and controlled chemistry.
Step 2: Ladle Refining
Molten steel is refined to adjust chemical composition and remove impurities.
Step 3: Continuous Casting Machine (CCM)
Liquid steel is cast into billets with consistent internal structure and dimensional accuracy.
Step 4: Automated Rolling Mill
Billets are rolled into TMT bars, structural sections, and square bars with precision shaping and rib patterns.
Step 5: QST (Quenching & Self-Tempering) Technology
A specialized water-cooling process creates a tough outer layer and ductile core—ideal for seismic conditions.
Step 6: Controlled Cooling & Cutting
Bars are cooled on automated beds and cut to exact lengths for reliable handling and use.
