Product Introduction
Processed Rebar
Processed rebar is made by shaping straight rebar or coiled rebar into an accurate form using an automatic cutting and bending machine. DaehanSteel's processed rebar is managed through an optimized program that oversees the entire process, from the input of rebar to cutting, bending, and discharge. Processed rebar produced in our state-of-the-art facilities ensures uniform shape and shortens the period of construction.

Types of
processing shapes
‘ㅡ’ shaped rebar
It is a rebar in an unprocessed state or a rebar that has been processed into a 'ㅡ' shape.
‘ㄷ’ shaped rebar
It is a rebar processed into a 'ㄷ' shape and is mainly used when anchoring within a single, non-continuous structure. The length of the member is usually the length of the single structure minus the cover thickness.
Hunch
In concrete structures, where there is a sudden change in the thickness or height of a member, the cross-section is gradually increased or decreased to prevent localized damage due to stress concentration. The form of rebar used in this area is called hunch rebar.
*It is mainly used in areas such as the step of foundations, beams, or horizontal bars in walls with bending shapes.
Spiral bar
It is a spiral bar wrapped around the main bar of a column and can accommodate a large load being strong against.
Bend Bar
It consists of main bar for beams or slabs that is bent twice at the boundary line (Lx/4) between the end and center. This construction method is primarily used in Korea and Japan, while most other countries use the cut bar method. In South Korea, the application of bend reinforcement in beams has largely disappeared, and it is only used in some slabs.
Auxiliary Bar (Cap Bar)
Auxiliary bar is a bent rebar attached to the upper open ribs of a beam. It helps prevent buckling of the main rebar in the column, with one end bent at 90 degrees and the other at 135 degrees to secure the main rebar.
* It can be processed at 90 degrees, 135 degrees, or both ends can be processed at 90 degrees. (D10, D13 rebar is primarily used.)
Shear Reinforcement Bar
Shear reinforcement bar is used in beams to counteract shear forces. It is designed perpendicular to the main reinforcement.
* The same size rebar as the rib is used, mainly D10, D13. The first shape in the top left is structurally ideal, but for construction convenience, the other two forms of shear reinforcement may be used after consultation with the site.
Main Reinforcement Bar
It connects the rebars of a column in the horizontal plane, preventing the main bars from pushing outward due to compression, thereby increasing the column's compressive strength and providing shear reinforcement.
* Various forms of main reinforcement are used depending on whether it is seismic, non-seismic, SRC, or based on the shape and size of the column. The first form of hoop on the left is used for seismic structures, the second for non-seismic structures, the third for SRC columns or when using couplers, or for the convenience of large-sized columns, and the 4th is used for circular columns. (D10, D13 rebar is primarily used.)
* The length of the main reinforcement bar is determined by subtracting the cover thickness from the width of the column.
