Steel Billet 125×125 mm | Export‑Grade Square Billet (3SP / 4SP / 5SP)

Product Overview

The 125×125 mm export‑grade steel billet is one of the key semi‑finished products in the steel production chain, widely used as the primary raw material in rolling mills to manufacture various steel sections. With a square cross‑section of 125×125 mm and availability in 3SP, 4SP, and 5SP grades, it offers excellent structural properties and rolling performance.

Thanks to its standard dimensions, clean surface quality, and well‑controlled chemical composition, the 125×125 billet is an ideal choice for producing rebar, angle bars, channels, wire rods, and other hot‑rolled steel products. It is manufactured according to commonly accepted steelmaking standards and is suitable for both domestic and export markets.

Full chemical analysis and a Mill Test Certificate (MTC) can be provided upon request. Export packaging, strapping, and land/sea transport options are also available for international buyers.
