Steel Wire Rods

Used for an array of products based on how it is formed and treated, steel wire rods can be used for wire mesh
manufacturing, the production of nails and springs, as reinforcement wire, barbed wire and even formed into
wire ropes or welded wire mesh.
Any steel wire rod is semi-finished and is cold drawn for further processing. Available in a variety of shapes from rounded, squared,
hexagonal or rectangular, it is typically rolled round. Diameters are going to range from
5mm to 15mm, with most adhering to the international ISO standards, allowing sizes to range from those
indicated above and upon reaching 15mm (in increments of .5mm until that point) advancing in increments of
1mm until a size of no greater than 20mm.
All steel wire rods is formed into coils and without break. This rolled condition is to ensure steel wire rods are
properly prepared for further processing (typically by cleaning, coating and heat treating). The internal diameter
of coils typically ranges from 810mm to 910mm, and the external from 1100mm to 1300mm (based on the
mill’s equipment capability). Weights on coils range accordingly with lower weights at roughly 600kg and
larger at more than two tons
Carbon steel wire rods are available in the following grades (Note, the “C” designates carbon):
Low C grades will have maximum C content of less than or equal to 0.15 %. This is also called mild steel or
electrode steel.
Medium C grades are high or low. The low will have maximum C content greater than 0.15 % but less or equal
to 0.23%, while the high grades will have maximum C content greater than 0.23 % but less or equal to 0.44 %.
High Carbon grades will have maximum C content greater than 0.44 %.
In addition to the grades of steel wire rods, there are also qualities that are guaranteed through various
procedures and intended to guarantee freedom from defects as well as the right performance based on
the intended application. The most common are:
