Generally, GB1499.2-2007 standard deformed steel bars are made using the hot-rolled method, meaning that these are the most common types of deformed steel bars. These are available in different lengths and sizes, all the way from 6 mm in diameter to 50 mm in diameter. When it comes to length, 9 m and 12 m are the common sizes.

Carbon Steel: Properties, Production, Examples and Applications
Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt.% carbon. For carbon steels, there is no minimum specified content of other alloying elements, however, they often contain manganese. The maximum manganese, silicon and copper content should be less than 1.65 wt.%, 0.6 wt.% and 0.6 wt.%, respectively.
Types of carbon steel and their properties
Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel . Their carbon content, microstructure and properties compare as follows:
