Steel Bars

There is no single specification for steel bars. Each will have to be ordered to the buyer’s needs and the appropriate specifications for the work at hand. American standard is not the only standard in the market, and almost all steel bars are going to be created using hot rolling or cold drawn processes.

The most common standards to be met are:
ASTM A36 / ASTM A283 /ASTM A572 /ASTM A656 /ASTM A131 /ASTM A516
JIS G3101 SS400. Q235 /Q345 /Q420

Manufacturing is often limited to hot rolled and/or cold drawn. Specifics for these two processes are below:

Hot Rolled

Used for general fabrication, transportation equipment, industrial maintenance, and agricultural gear, it will be formed into flat, round or square bars. It will need to meet certain grading standards:

A36 / A572-50 / A529-50 / HRCQ / 1018 SBQ / 1045 SBQ

Cold Drawn

Crafted of SBQ HR bars, cold drawn bars are drawn through dies to be reduced to a specific shape and finish. Typically, round, square or flat they offer greater accuracy where size, straightness and tensile strength are concerned and offer greater machinability. They must meet certain standards, too, including:

CD 1018 / CD 1045 / 12L14

Buyers can order steel bars in inches or millimeters and will need to recognize the appropriate nominal weight often noted as kg/m. This will also depend upon the bars in question. The most common include:

Flat Bar

Commonly used to create braces, brackets, ornamental work and base plates, it can range in thickness from 1/8″ to six inches. It can be made from hot rolled steel or cold drawn steel.

Round Bar

Long and cylindrical stock is used in a huge number of commercial and/or industrial settings. Typically, round bar steel is used in shafts and can range in diameter from 1/4″ to 24″. It can be made from hot rolled steel or cold drawn steel.

Equal Angle and Unequal Angle

Equal angle is used for industrial construction and structures. It will appear in thicknesses of 3/16 of an inch to more than 3/8 of an inch. The sizes will range from under one inch to more than 6″ and the out of square variations can range by 1.5 degrees. Unequal angle bars are steel milled with different side lengths and often used for bridges, vehicles, workshops and construction.

Both are made in sizes measured by width x width x thickness. These are often found in structural steel grades.

IPN Bar

A bar shaped to serve as a building element or beam, and typically with an inclined internal surface. It typically conforms to European standards according to DIN 125 and EN 10024: 1995, American beams S and wide flange beams and Asian universal beams UB and UC.

UPN Bar

Channel beams similar to IPN Bars and which serve as a building element. Conforming to European standards EN 10279, American C channels, BC bar channels, and Asian C standard sizes.

T Bar

Less common in structures, but gaining ground they will need to meet EN 10055, American ASTM A 484 and ASTM A1069.

Diverse in sizing and standardization, it is important to have optimal control when buying steel bars. We have all of the standard sizes and grades available and its steel bars are produce in the very best mills the European Union and Asia.
