**Introduction to Steel Billet**

Steel billet is one of the most important semi-finished products in the steel industry, serving as the main raw material for producing rebar, wire rod, and other long steel sections. Billets typically have a square cross-section and are produced and supplied in various lengths.

**Dimensions and Specifications**

Billets are most commonly produced with square cross-sections of 100×100 mm, 120×120 mm, and 150×150 mm. The chemical composition of a billet is adjusted based on the customer’s required steel type — such as A2, A3, A4, or various construction and industrial grades.

**Production Process**

Billets are produced through continuous casting of molten steel. After leaving the furnace and going through refining stages, the molten steel enters the casting machine and solidifies into square sections inside special molds. These sections are then cut and prepared for delivery to rolling mills.

**Applications of Billet**

– Main raw material for rolling rebar
– Production of wire rod and industrial wires
– Manufacturing certain light steel sections

**Key Features of Billet**

– Consistent quality and uniformity in surface and dimensions
– Controlled chemical composition
– Suitable mechanical properties for hot rolling

**Factors Affecting Billet Prices**

Billet prices are influenced by steel ingot prices, energy costs, exchange rates, demand from rolling mills, and global steel market conditions. In Iran, billet prices are typically determined based on announced rates from the Iran Mercantile Exchange and the open market.
