Classification of rebar

The difference between ordinary steel bar and deformed steel bar
Both Plain Bar and Deformed Bar are steel bars. These are used in steel and concrete structures for reinforcement. Rebar, whether plain or deformed, helps make buildings more flexible, stronger and more resistant to compression. The main difference between ordinary steel bars and deformed bars is the outer surface. Ordinary bars are smooth, while deformed bars have lugs and indentations. These indentations help the rebar grip the concrete better, making their bond stronger and longer lasting.

When choosing a builder, they tend to choose deformed steel bars over ordinary steel bars, especially when it comes to concrete structures. Concrete is strong by itself, but under stress it can easily break due to its lack of tensile strength. The same is true for supporting with steel bars. With increased tensile strength, the structure can withstand natural disasters with relative ease. The use of deformed steel bars further increases the strength of the concrete structure. When choosing between normal and deformed bars, for some structures the latter should always be chosen.

different rebar grades
There are quite a few steel bar grades available for different purposes. These steel bar grades vary in composition and purpose.

GB1499.2-2007 is the European standard steel bar. There are different steel bar grades in this standard. Some of them are HRB400, HRB400E, HRB500, HRB500E grade steel bars. GB1499.2-2007 standard rebar is generally produced by hot rolling and is the most common rebar. They come in different lengths and sizes, ranging from 6mm to 50mm in diameter. When it comes to length, 9m and 12m are common sizes.

BS4449 is another standard for deformed steel bars. It is also differentiated according to European standards. In terms of fabrication, the bars that fall under this standard are also hot rolled which means that they are also used for general purpose i.e. common construction proje
