How Is Rebar Made?

If you’ve ever had a concrete surface poured at your home, such as a driveway or patio, you’ve also had a key component installed – rebar.

First thing to remember, rebar is reinforcing bar. Steel bars are used as rebar because the elongation of steel due to high temperatures (thermal expansion coefficient) nearly equals that of concrete. Therefore, rebar is incorporated to reinforce concrete and impart the tensile strength needed to make sure concrete stays in place. Since concrete naturally expands, the product helps keep the concrete in check, making sure it will last as long as your structure does.

How Is Rebar Made?

From Scrap Steel

Most rebar produced is produced using an EAF steel making process, or Electric Arc Furnace. Here, scrap steel is collected from various sources at the steel mill and put into a large furnace where the steel is then melted at temperatures up to 1,630’C. In this state, the molten steel will be poured into a ladle.

Molten Steel

Then, the molten steel is taken to a Ladle Furnace where the required alloying additions are made, steel cleanliness and homogeneity are assured, as well as, the steel temperature is raised to casting temperature. The steel is then teemed from the ladle into a tundish. The tundish is used to feed the steel into the casting molds. In fact, this method also gives the molten steel a smoother flow. Following, the molten steel is poured into a series of casting molds that gives the steel its mid product shape. As a result, the shapes formed are known as billets which are used later in the process of forming the rebar.

ROLLING MILL

The rolling mill is comprised of an annealing furnace, and roughening mill stands, intermediate and finishing stands to obtain the required size rebar.

Rough Mill Section

After the billet leaves the caster, it then goes into the roughing mill. At the roughing mill, the larger billets will be hot rolled into small shapes by continuously reducing the billet at each stand on the roughing portion of the mill.

Intermediate and Finishing Sections

After the roughing mill section, the worked billets pass through the intermediate section of the rolling mill. As it goes through the stands, at this section, the billets begin to take shape into the bars. After the intermediate section of the mill, the bar passes through the finishing section which gives its final shape and that “tied knot” look that is ideal for reinforcing applications.

Cut to Size

From here, the bars enter the cutting section; typically, a flying shear saw to specific lengths that are programmed in by the mill operator. Then, the bars exit onto a cooling bed! The cooling section of the mill is used so the material is cooled back to room temperature before the product is sheared to the final customer specific length.

Shipped

Overall, rebar is then bundled using automated bundling systems to the customer’s specifications. The product is usually transported by a flatbed trucks.

Rebar Sizes

At Contractors Steel, we carry rebar to the B500BWR Grade 60 specification in the following sizes:
