Steel Billet 130×130 mm | Export‑Grade Square Billet (3SP / 4SP / 5SP)

Product Overview

The 130×130 mm export‑grade steel billet is one of the most widely used and internationally standardized semi‑finished products in the steel industry. It serves as the primary feed material for rolling mills producing rebar, angle bars, U‑channels, steel joists, wire rod, and a variety of other hot‑rolled steel sections. Manufactured with a square cross‑section of 130×130 mm, this billet is available in 3SP, 4SP, and 5SP grades to meet different mechanical and metallurgical requirements.

With its balanced dimensions, optimal weight, clean surface quality, and controlled chemical analysis, the 130×130 billet is a popular choice among steel mills targeting both domestic and export markets. The product conforms to globally recognized standards and can be supplied with a Mill Test Certificate (MTC) for export shipments.
