Product Description

Product Overview

Hot rolled square steel bar is solid square-section steel formed by heating steel billets and continuous high-temperature hot rolling. As essential structural raw material, it is widely adopted in construction, machinery processing and hardware manufacturing. Controlled hot rolling removes internal casting defects and obtains uniform microstructure for stable mechanical performance. With outstanding cost performance and good secondary processability, it becomes a preferred blank for various mechanical parts.

Product Features

Compact internal structure, uniform density and excellent toughness. Fine grain brings good tensile strength and impact resistance. Great weldability, ductility and machinability to support cutting, forging, bending, drilling and CNC processing. Stable performance under normal and medium-heavy load working conditions.

Core Advantages

Strict raw material inspection and standardized rolling guarantee stable chemical composition and consistent batch quality;
Precise dimension control with tight tolerance to reduce customer’s processing loss;
Smooth surface with fewer pits, cracks and burrs to save finishing cost;
Complete stock standard sizes, non-standard dimension customized per drawings.

Typical Uses

Widely used for mechanical accessories, equipment base, building steel frame, vehicle spare parts, agricultural machinery components, fence support, mold preform and hardware forging blanks. Ideal raw material for connecting parts, shaft blanks and structural supports after machining and forging.
