Low Carbon Wire Rod

low carbon Wire rods made have a lot of usage in the industry such as the manufacturing of welding wires and electrodes.

Considering the sensitivity of chemical analysis of these wire rods the electrodes and welding wires made of the aforesaid wire rods will have the proper chemical compound and microscopic structure.
Low carbon wire rod is also used in the manufacture of cold heading/cold forging quality steel wire and hard drawing wire. these kinds of steel are within carbon limits 0.04-0.22 and they have various applications in screws & nuts, cold forged parts, plated wires (galvanized rods), various kinds of nets, nails and bolts.

Average Carbon Steel Rod

Micro-alloy steels, boron steels and medium carbon wire rods Used in production of cold headed wire rod:

These kinds of steel contain medium carbon without such elements as Ni, Cr, Mo, Or B. they are in the form of alloys and used in making high strength bolts, parts with cellular hardening, cold forged parts, and cold extruded parts.

High Carbon Steel Rod


This wire rod is used as a preliminary material for the manufacture of a wide range of welding wires. Like other types of wire rods, welding wire rods have different grades for different uses.

Manufacturing of atmosphere protected with CO2 welding needs SG2 or SG3 wire rod and submerged arc welding needs electrodes that have made by S2 wire rod

We have other grades in this field like SWRY11, SWRY21 and USD 7 that each one has its own use in industry.

STC provides all types of this wire rod and supplies it with high quality for electrodes and welding wire manufacturer.
