Finished rolled rebar classification

2023-09-12 page view: 95

Finished rolled rebar classification


This article aims to provide a comprehensive understanding of the classification of finished rolled rebar. The classification of finished rolled rebar holds great importance in the construction industry as it ensures the appropriate selection of rebar for different structural requirements. It is crucial for readers to grasp the background information regarding the classification of finished rolled rebar to fully comprehend its significance. In this article, we will delve into the topic from four different aspects, discussing the various types of rebar, their characteristics, applications, and quality standards. By exploring these aspects, readers will gain valuable insights into the classification of finished rolled rebar.

1. Types of rebar

Rebar, short for reinforced bar, comes in various types, each suited for specific construction needs. The first type is carbon steel rebar, which is the most common and widely used due to its cost-effectiveness and desirable mechanical properties. Stainless steel rebar, on the other hand, offers exceptional resistance to corrosion and is frequently employed in coastal applications. Additionally, epoxy-coated rebar is extensively used in projects where high resistance to corrosion is a primary concern. Lastly, galvanized rebar is chosen for its excellent corrosion resistance as well as ease of maintenance. Understanding the characteristics of each type is essential in ensuring the proper selection for construction projects.

2. Characteristics of finished rolled rebar

Finished rolled rebar possesses distinct characteristics that influence its structural performance. One crucial characteristic is the diameter, which varies based on the intended application and the specific structural requirements. Moreover, finished rolled rebar exhibits different tensile strengths, yielding strengths, and elongation percentages. These mechanical properties directly impact the rebar's load-bearing capacity and ability to withstand external forces. Furthermore, the surface of finished rolled rebar can be smooth or deformed, with the latter offering enhanced bond strength between the rebar and the surrounding concrete. Familiarizing oneself with these characteristics allows for informed decision-making during the rebar selection process.

3. Applications of finished rolled rebar

Finished rolled rebar finds widespread application in the construction industry. It is extensively used in reinforced concrete structures such as buildings, bridges, highways, and dams. In building construction, rebar provides the necessary strength and durability to withstand various loads. Bridges and highways utilize rebar to enhance structural stability and resist the detrimental effects of traffic and environmental factors. Dams, subjected to immense hydraulic forces, rely on rebar reinforcement for robustness. Understanding the versatile applications of finished rolled rebar is crucial for engineers and construction professionals alike.

4. Quality standards

To ensure the safety and reliability of construction projects, quality standards for finished rolled rebar have been established. These standards encompass aspects such as chemical composition, mechanical properties, and dimensional tolerances. One internationally recognized standard is ASTM A615, which outlines the requirements for carbon steel rebar used in concrete reinforcement. Other countries and regions have their respective standards, such as BS 4449 in the United Kingdom and JIS G3112 in Japan. Adhering to these quality standards guarantees the use of high-quality finished rolled rebar, contributing to the overall integrity of a structure.


The classification of finished rolled rebar plays an integral role in the construction industry. By understanding the various types, characteristics, applications, and quality standards, construction professionals can make informed decisions regarding the selection and use of rebar. It is crucial to consider the specific requirements of a project to ensure the appropriate choice of rebar. With proper classification, the structural integrity and safety of reinforced concrete structures can be effectively guaranteed. Moving forward, further research may be conducted to explore advancements in rebar technology and its impact on the construction industry.
