Material and shape
Round steel: Round steel is a solid long steel strip with a circular cross section, usually made of carbon structural steel or alloy structural steel. Depending on the use, round steel can be divided into hot-rolled round steel, forged round steel and cold-drawn round steel. Its circular cross section allows round steel to have uniform force performance when subjected to loads such as pressure, bending and torsion.
Conventional steel: Conventional steel covers common types of steel, including but not limited to steel plates, steel sections (such as angle steel, channel steel, I-beam), steel pipes, etc. These steels have different shapes to meet different engineering needs. The materials of conventional steel are also diverse, ranging from low-carbon steel to high-strength steel, and even stainless steel, alloy steel, etc., to meet the strength and corrosion resistance requirements of various application scenarios.

Performance comparison
Round steel usually has high strength and toughness, and can withstand large loads and deformations. At the same time, round steel has excellent processing performance and is easy to cut, weld and forge.
Conventional steel exhibits different mechanical properties, corrosion resistance and welding properties depending on its specific type and material. For example, stainless conventional steel has excellent corrosion resistance and is suitable for harsh environments; high-strength conventional steel has higher yield strength and tensile strength and is suitable for structures that bear heavy loads.

Differences in production processes
Round steel is usually produced by hot rolling or forging. Hot-rolled round steel is made by heating the steel billet to a certain temperature and then rolling it multiple times on a rolling mill. Forged round steel is made by repeatedly hammering or extruding the steel billet through forging equipment to obtain the desired shape and properties.
The production process of conventional steel is more diverse, including hot rolling, cold rolling, extrusion, welding and other methods.
