1. OVERVIEW OF HOT ROLLED STEEL COIL

Hot-rolled steel is produced from slab billets that go through several processes such as reheating, descaling, rough rolling, finish rolling, surface cooling, and coiling, forming hot-rolled coils. The Hot Rolling Mill has a planned production capacity of 5.2 million tons/year, with thickness ranging from 1.2 – 25.4mm and width from 900 – 1880mm.

After quality adjustment and inspection, the hot-rolled coils become finished hot-rolled steel products. In addition to being the raw material for cold-rolled products, hot-rolled steel has sufficient strength, good hardness, and excellent formability, making it widely applicable for various purposes.

Our company applies the latest production technologies, automated equipment, and computer-based management systems to ensure high dimensional accuracy and specific product characteristics. Through strict quality control, the hot-rolled steel produced demonstrates outstanding performance in appearance, dimensional precision, mechanical properties, and processability. Depending on product features, the coils can be used as general-purpose products, rerolling materials, or structural materials. The products are certified under the ISO 9001 Quality Management System and exported to many countries such as Taiwan, Thailand, Indonesia, the Philippines, Malaysia, etc.

2. PRODUCTION PROCESS OF HOT ROLLED STEEL COIL

The hot-rolled steel manufacturing process includes ironmaking, steelmaking, hot rolling, and processing. This ensures the quality and uniformity of hot-rolled steel.

• Ironmaking: Raw materials such as iron ore and carbon are melted in a blast furnace, removing impurities and producing molten iron.
• Steelmaking: The molten iron is transferred to a steelmaking furnace, where its chemical composition is adjusted, and remaining impurities are removed. Alloying elements may be added to achieve the desired properties.
• Hot rolling: The molten steel is cast into slabs and sent to hot rolling units, where it passes through rolling mills under high pressure and temperature to form hot-rolled sheets with required strength and ductility.
• Post-rolling processing: The hot-rolled sheets may undergo cutting, bending, welding, and surface treatment to achieve the final specifications.
• Heat treatment & surface finishing: Additional processes such as hardening, tempering, pickling, coating, or painting may be applied to improve mechanical properties and surface quality.

All production parameters—temperature, pressure, and rolling speed—are strictly monitored to meet technical requirements and international standards.
