Reinforcement Bars


  • Deformed Bars: 08mm - 40mm
  • Plain Bars : 08mm - 32mm

PT Cakra Tunggal Steel manufactures a range of rebar products and they are available in different grades and specifications that vary in yield strength, ultimate tensile strength, chemical composition, and percentage of elongation while maintaining close dimensional tolerances and required mechanical properties.

All products of PT Cakra Tunggal Steel follows Standar Nasional Indonesia - SNI 2052:2017 which is BJTP 280 for plain bars and BJTS 420 and BJTS 520 for deformed bars.

This is a part of our commitment to adhere to the Government Laws about “SNI Wajib” and our way to ensure the best quality products and highest satisfaction to our customers.

Cakra Steel reinforcement bars (steel rebars) come with a series of inherent advantages like consistent quality along with uniform grades, dimensions, and tolerances. It also comes with superior stability, properties for higher durability, and easy workability. The integrated steel plant at Jln. Raya Bekasi Jakarta Timur has Direct Reduce Iron Unit, Steel Melting Unit(EAF), Continuous Billet Casting Mill, sophisticated Rolling Mill, and fully-equipped Testing laboratories - all under one roof. The Company has received ISO Award 2008, ISO 17025:2017, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018.

Cakra Steel is offering the widest range of construction steel. Its range of Steel Rebars suffices the rarest need of a civil engineer. The range of Structural Steel offered by the company meets the maximum demands of the engineering sector.

Cakra Steel Rebars Competitive Advantage

CS steel, it has High Strength for Critical Applications

Cakra Steel has some special grades of Steel Rebars produced under specific process conditions resulting in increased strength as compared to the grades of Steel Rebars. Our steel rebars are ideal for applications in heavy load structures like flyovers, dams, bridges, and other critical structures where high yield load (design load) is required without compromising on the ductility.

In addition to the features of Cakra Steel Rebars exhibit the following characteristics:

  • Earthquake Resistance
  • Special Weldability : Cakra Steel Rebars do not require pre or post welding treatment as they have low carbon content and are produced under controlled thermomechanical treatment.
  • Higher Corrosion Resistance: The controlled thermomechanical treatment also results in a uniform and thick tempered martensitic rim, completely free from internal stress. This martensitic rim improves the corrosion resistance as well as fatigue strength of Cakra Steel Rebars when compared to other rebars.

Note: Customized sizes based on other international standards available upon reques. The minimum order applies.
