BEKASI, INDONESIA, October 11, 2026 /24-7PressRelease/ — Infrastructure development, industries facilities and building construction require a steady supply of structural steel with dimensions, mechanical properties, chemical composition, and Mill Test Certificate that meet engineering requirements. The material is widely used in commercial buildings, warehouse construction, bridge construction, industrial facilities and energy infrastructure, forming part of broader steel construction and steel structure systems.
This demand places domestic manufacturers and steel suppliers within a broader construction supply chain. Contractors and fabricators planning to buy steel need to consider specifications, grades, applicable standards, documentation and delivery schedules before fabrication begins.
One company producing hot rolled structural steel profiles in Indonesia is PT Garuda Yamato Steel (GYS), a steel manufacturer Indonesia developers can approach, operating as a steel mill in Indonesia from Cikarang, Bekasi, West Java.
PT Garuda Yamato Steel (GYS) manufactures H-Beam, IWF (commonly referred to in the market as WF steel or Wide Flange Steel), U Channel, and Equal Angle through a hot rolling process. In this process, heated steel is progressively passed through a series of rolling stands and shaped into the required dimensions and cross-sectional profiles. These products are commonly categorized as hot rolled structural steel sections or section steel and are used in various structural applications, including beams, steel columns, bracing members, and other load-bearing components.
Through controlled production, GYS produces hot rolled structural steel with consistent dimensions and the required mechanical properties and chemical composition according to the applicable steel grade and specification. GYS also utilizes Electric Arc Furnace (EAF) technology, supporting the use of recycled steel and a more circular steelmaking process while delivering structural steel products suitable for construction and engineering applications.
H-Beam and IWF can be specified as beams or columns depending on structural calculations. U Channel and Equal Angle may be used for secondary framing, bracing, supports, machinery components or connection elements.
For that reason, hot rolled steel profile selection cannot be based only on nominal dimensions. Project teams need to review H-beam sizes, flange width, web thickness, flange thickness, weight per metre, material grade, applicable standard, and required length. Dimensional information is generally referenced from a steel profile table or product catalogue, while material grade, chemical composition, mechanical properties, and production traceability can be verified through the Mill Test Certificate (MTC). Profiles with similar nominal heights can still have different weights, mechanical properties, and structural applications.
GYS produces its steel profiles through an integrated manufacturing process that starts with steel scrap as the primary raw material. The scrap is melted and refined in an Electric Arc Furnace (EAF), then continuously cast into semi-finished steel products such as beam blanks, blooms, and billets. These semi-finished products are subsequently reheated and processed through the rolling mill, where they are progressively shaped into finished hot rolled steel profiles such as H-Beam, IWF, U Channel, and Equal Angle. The process continues through cooling, straightening, cutting, marking, and final inspection to ensure each product meets the required specification. This manufacturing route enables GYS to produce a wide range of structural steel profiles, including high-strength steel and products developed for seismic-resistant structural applications in Indonesia.
Quality verification throughout the process can include checks on chemical composition, mechanical properties such as yield strength, tensile strength, and elongation, dimensional tolerance, surface condition, product marking, and traceability, depending on the applicable product standard and steel grade. Together, these controls help ensure that the finished steel profiles achieve the required consistency, performance, and compliance for structural and engineering applications.
Tony Taniwan, President Director of PT Garuda Yamato Steel, said demand for structural products is coming from several construction sectors.
“We are seeing continued demand for structural products across different construction sectors across Indonesia. Our focus is to coordinate production, processing, and delivery so customers receive accurate information regarding specifications and schedules,” Tony said.
Material availability remains an important issue because delays involving a single profile can interrupt fabrication even when workers, machinery and other components are already available. Domestic production can shorten communication channels for confirming specifications, documentation and delivery planning.
Steel profiles may also require additional processing before fabrication or installation. GYS operates a Steel Service Center for processes including CNC drilling, cutting, sawing and straightening. Buyers with confirmed requirements may choose to buy steel directly from the mill, while smaller or urgent orders may be sourced through distributors holding local stock.
Domestic hot rolled structural steel production therefore forms one part of Indonesia’s construction material supply chain. Descriptions such as the largest steel mill in Indonesia, the best steel mill in Indonesia, or a steel mill with the best quality in Indonesia should be verified against documented capacity and certifications rather than accepted without evidence. Final product selection, however, remains dependent on engineering calculations, project specifications and the standards applicable to each structure.
