Mild Steel Plate Manufacturing Plant Project Report 2026: Cost Analysis, ROI, and Feasibility Insights

The manufacturing process uses hot rolling. Iron ore, coke, and limestone are processed in a blast furnace to produce molten iron, which is converted into steel and continuously cast into slabs. The slabs are then rolled to the required thickness and dimensions. Heat treatment may include heating, quenching, reheating, and controlled cooling to achieve the required toughness and ductility.

Key raw materials include iron ore, coke, limestone, scrap steel, refractories, and electrodes. Raw materials are the largest cost component in integrated steelmaking. As an external industry benchmark, raw materials accounts for about 55.8% of total steel production costs for one integrated steel producer.

Asia, particularly China, dominates global steel manufacturing. A specific global supply share for mild steel plate is not publicly available. As a broader benchmark, China accounts for approximately 53.3% of global crude steel production.

Mild steel plate typically contains around 0.05% to 0.25% carbon by weight. Formats mentioned include slabs and sheets, with finished plates supplied in different thicknesses and dimensions according to application requirements.

There is no universal minimum recycled-content requirement for mild steel plate. Recycled steel content depends on the production route. The BF-BOF route uses about 125 kg of recycled steel per 1,000 kg of crude steel on average, while the recycled-steel EAF route uses about 710 kg per 1,000 kg. Manufacturing and procurement are also affected by environmental regulations, carbon-pricing systems, emissions requirements, applicable material standards, and mill test certification. For steel imported into the European Union, covered iron and steel products are subject to the EU Carbon Border Adjustment Mechanism.
