Billet Steel: The Backbone of Modern Manufacturing

Published on July 21, 2025 | Mulia Steel – Your Trusted Supplier of High-Quality Steel Billets

Billet steel is more than just raw material — it’s the foundation of modern manufacturing. At Mulia Steel, we specialize in high-quality billet steel that powers industries from construction to automotive. Discover why billet steel is essential, how it’s made, and how we ensure consistent quality for your production needs.

Billet Steel: What Is It?

Billet steel is a semi-finished metal product with a square or rectangular cross-section, typically measuring 100mm to 150mm per side. It’s produced through continuous casting or hot rolling and serves as the primary raw material for long steel products such as:

• Rebar and structural beams
• Wire rods and fasteners
• Shafts, axles, and mechanical components

Thanks to its strength, malleability, and consistency, billet steel is a preferred choice across heavy industries.

The Production Process of Billet Steel

At Mulia Steel, our billet production follows a precise, controlled process to ensure maximum quality and performance:

1. Steel Melting

We melt raw materials — including scrap metal and iron ore — in an Electric Arc Furnace (EAF) or Basic Oxygen Furnace (BOF). This ensures a clean, uniform melt with controlled chemical composition.

2. Continuous Casting

Next, the molten steel is poured into molds via a continuous casting machine, forming solid billets. This method ensures consistent dimensions and internal structure.

3. Reheating & Hot Rolling (if needed)

After casting, we reheat billets and pass them through rolling mills to achieve precise dimensions and improved mechanical properties. This step is crucial for applications requiring high strength and durability.

4. Cooling & Quality Inspection

Then, billets are cooled under controlled conditions and undergo rigorous inspection for:

• Dimensional accuracy
• Surface quality
• Chemical composition (SNI compliance and international standards)
• Mechanical properties (tensile strength, yield strength)
