Structural steel is a steel material used as a primary load-bearing element in construction projects, including building frames, bridges, warehouses, and industrial facilities. It is widely used due to its high strength, dimensional accuracy, and consistent quality.

To learn more about commonly used structural steel types and specifications, please refer to the IW Steel product specification page.

Reinforcing steel, commonly known as rebar, consists of steel bars used to strengthen reinforced concrete structures. Its primary role is to resist tensile forces, helping concrete structures withstand loads without cracking or structural failure.

Information on reinforcing steel types, sizes, and quality standards is available on the IW Steel reinforcing steel product page.

Construction steel is a broad term that refers to iron and steel materials used in construction, both for structural and supporting purposes. Common examples include reinforcing bars, structural steel profiles, hollow sections, angle bars, and steel pipes.

To explore the full range of construction steel products and their specifications, please visit the IW Steel product catalog page.

Plain rebar is a type of reinforcing steel characterized by a smooth surface and the absence of ribs. It is typically used for ties, stirrups, or secondary reinforcement to help maintain the position and alignment of the main reinforcement within concrete structures.

Details on available sizes and specifications of plain rebar can be found on the IW Steel rebar product page.

The primary difference lies in surface texture and bonding performance. Plain rebar has a smooth surface and is easier to bend, while deformed rebar features ribs that provide improved bonding with concrete, making it more suitable for primary reinforcement.

For a detailed technical comparison, you can review their specifications on the IW Steel rebar product page.

Reinforcing steel grade refers to the classification of steel based on its mechanical properties, including yield strength, tensile strength, and ductility. The selected grade directly influences the load-carrying capacity and performance of reinforced concrete structures.

Information on the reinforcing steel grades used in IW Steel products is available on the Reinforcing Steel Specification page.

The reinforcing steel grade plays a critical role in ensuring structural safety and long-term durability. Using the correct grade helps reinforced concrete structures perform as designed and reduces the risk of premature deterioration or structural issues.

For this reason, it is essential to choose reinforcing steel with clear and verified technical specifications, as listed on the IW Steel product page.

SNI rebar refers to reinforcing steel that complies with the Indonesian National Standard (SNI). This standard specifies technical requirements such as dimensions, tolerances, and mechanical properties to ensure safe and reliable use in construction projects.

Rebar specifications that comply with this standard can be reviewed on the IW Steel rebar product page.

For structural construction projects in Indonesia, the use of SNI-compliant rebar is strongly recommended to ensure safety, quality consistency, and compliance with engineering requirements.

IW Steel provides reinforcing steel products that comply with applicable standards, which can be reviewed on the product specification page.

Selecting the appropriate construction iron and steel depends on the structural function, design loads, and required quality standards. Reviewing product specifications and material properties is essential to ensure suitability for the intended application.
