Round steel refers to a solid long steel bar with a circular cross section. Its specifications are expressed in diameter, in millimeters (mm). For example, "50mm" means a round steel with a diameter of 50 mm. Round steel is mainly used to manufacture mechanical parts, as seamless steel pipe billets, or for construction and hardware accessories. ‌

Galvanized tubes, also known as galvanized steel tubes, are mainly divided into two types: hot-dip galvanizing and electro-galvanizing (cold-dip galvanizing). Hot-dip galvanizing is a process in which a steel pipe substrate undergoes a complex physical and chemical reaction with the molten plating solution to form a corrosion-resistant, tightly structured zinc-iron alloy layer with strong corrosion resistance. The commonly used specifications are +12.5~+102mm2. In contrast, the amount of galvanizing in electro-galvanizing (cold-dip galvanizing) is less, only 10-50g/m², and its corrosion resistance is much worse than that of hot-dip galvanized pipes.

Galvanized sheet is a metal sheet made by coating the surface of carbon steel with a zinc layer. The purpose of galvanizing is to increase the corrosion resistance of carbon steel plates and extend their service life. Galvanized sheets are commonly used in construction, manufacturing, automotive manufacturing, and other areas.
