Kinsteel produces mild steel round bars, high tensile deformed bars, angle bars and flat bars servicing, in particular, the construction and infrastructure industries. There steel bars and sections manufactured by Kinsteel are also generically known as “long products”.
Currently, Kinsteel Bhd has eight production lines with a total steel bars production capacity of 800,000 metric tonnes per annum. The types of steel bars produced are round and deformed bars, angle bars, U-channel, wire rods and flat bars.
Kinsteel has been awarded on our outstanding product quality, including:

Upstream
Direct Reduced Iron (DRI)
DRI is mined iron ore (in pellet, lump or fine form) that has undergone a process of chemical reduction to remove the oxides from the iron ore. A reducing agent is introduced to the iron ore. A series of chemical reactions occur under high temperature in the presence of a catalyst. The maximum reduction rate is about 95%, and the result is DRI with iron content (purity) of up to 97%.
The resulting DRI is produced in the form of small pellets or lumps. DRI is also known as sponge iron due to its spongy or cell-like microstructure. The relatively small pellet size and the spongy microstructure create a relatively large surface area to volume ratio, which makes re-melting easier. However, it also makes DRI more sensitive to reoxidation and ignition.
DRI can be used to produce a very wide range of steel and other ferrous metal alloys, including carbon steel, tool steel, and stainless steel. As a refined form of iron, DRI can be used as the starting point for the production of practically all types of steel. DRI is primarily used as feedstock for the production of semi-finished long steel products (blooms, billets and beam blanks) and semi-finished flat steel products (slabs).
Semi-finished long steel products
Semi-finished steel products are steel products that require further rolling or forging to produce finished products.

Billets
Billets are semi-finished lengths of continuously cast steel, of square or rectangular cross-section with width of two to seven inches. Billets are used primarily as feedstock for hot rolling or other processes to produce sections, rods, bars and wire products. A billet is a smaller sized bloom. |

Blooms
Blooms are semi-finished lengths of continuously cast steel, of square or rectangular cross-section of width more than eight inches. Blooms are used primarily as feedstock for hot rolling to produce heavy sections and beams. A bloom is a bigger sized billet. |
|
Beam blanks
Beam blanks are semi-finished lengths of continuously cast steel, used primarily as feedstock for hot rolled I-beams or H-beams. The cross-section of a beam blank is not regular and resembles that of an I-beam or H-beam. Beam blanks are typically larger than a billet. Since beam blanks are in the approximate shape of the final product, using beam blanks instead of bloom or billets uses less energy, thus providing cost savings. |
Midstream
Round Bar and Deformed bar
Round and deformed bar are primarily used in the construction of concrete structures such as the structures of buildings and infrastructure projects (eg. bridges and dams). Round bars are also widely used in light structural construction as well as in the manufacturing of secondary long products such as bolts, nuts, nails, cables, shafting bars and welding electrodes.
Flat bar and Angle bar
Flat bars and angle bars are generally used for the construction of factories, warehouse building and fences.
U-channel bar
U-channel bars are mainly used for fabrication works in the manufacturing, construction, warehouse building and infrastructure sectors.
Downstream
Sections
Sections are transformed from blooms or beam blanks through hot rolling process. They are generally used in the structural frame for buildings as well as other general applications in the civil, marine, oil and gas industry.
Drawn Wires
Drawn wires are produced from repeated drawing of wire rods through progressively smaller dies into the desired diameter and properties, such as ductility and conductivity. Types of the drawn wires produced by Kinsteel include ordinary low carbon steel, hard drawn wires and zinc-coated steel wires.
