  • Materials

    Coiled steel

    Coiled steel from major steel manufacturers is delivered.

  • Coating
  • Coating

    Coating

    The surface of the coiled steel is coated to prevent the material from burning when it is drawn through the die.

  • Feeding

    Feeding

    The coiled steel is set on the drawing line to be fed through the die.

  • Drawing/cutting

    Drawing/cutting

    The material is passed through the die and drawn to the prescribed shape and dimensions.
    The drawn material is cut to customers’ desired length using an inline machine.

  • Straightening

    Straightening

    The material is straightened to improve the straightness of the product.

  • Straightening

    Inspection

    The product is carefully checked to ensure that it meets quality standards.

  • Packing and shipping

    Packing and shipping

    The product is packaged to customers’ specifications and then shipped.

  • Materials

    Bar steel

    Bar steel from major steel manufacturers is delivered.

  • Pointing for drawing

    Pointing for drawing

    The tip of the bar steel is tapered to adjust the outer diameter so that it can be fed through the die for drawing.

  • Coating

    Coating

    The surface of the bar steel is coated to prevent the material from burning when it is drawn through the die.

  • Drawing

    Drawing

    The tapered tip through the swaging process is fed into the die and drawn to form the various shapes and dimensions.

  • Heat treatment

    Heat treatment

    The material is heat-treated at various prescribed temperatures to stabilize its structure.

  • Acid pickling

    Acid pickling

    The material is rinsed to remove films and scales from the surface.

  • Cutting
