What is rebar? The section below, MRS Steel will help you answer questions about this type of steel.
What is rebar made of?
Rebar is also known as a “reinforcing bar” or “reinforcement bar”. Iron ore or scrap steel is the primary raw material used to make this kind of steel. For industrial and civil construction projects that demand a high degree of strength and durability, rebar is one of the steel types with long bar structures. For this reason, rebar is frequently utilized in concrete buildings, homes, etc.
Rebar usually has a length of 11.7m/tree and depending on the customer's needs, choose a product with a corresponding diameter of 10mm to 40mm. Normally, rebar steel is bundled with a weight of no more than 5 tons and fixed with at least 3 steel wires or straps.

Rebar steel production process
In the above section, we have answered your question “What is rebar?” For more information about the rebar production process, read the section below.
Step 1 - Processing input materials: Input materials are iron ore or scrap steel, which will have impurities removed. Then, it is transferred to the kiln and combined with other materials such as coal, limestone,...
Step 2 - Create a stream of molten steel: After being processed, the ore is put into the blast furnace to be heated to create a stream of molten steel.
Step 3 - Continuous Casting: The steel in the furnace is molten and formed into a billet.
Step 4 - Product formation: After going through the continuous casting process, the steel billet is formed. Here, steel billets will be drawn and made into rebar steel for construction projects.
