What is Steel Phi 12? What is the weight of each Steel Phi 12 bar? These questions are quite common nowadays. So if you are looking for answers to these queries, the following article will provide detailed explanations for your reference.

Definition of Steel Phi 12:

Steel Phi 12 (D12) is a type of steel material with a cross-sectional diameter of 12mm, and it is an indispensable product used in construction companies. The length of each Steel Phi 12 bar is typically about 11.7 meters.

Steel Phi 12 is produced by heating them at high temperatures, which gives it outstanding properties such as excellent heat resistance, good load-bearing capacity, and oxidation resistance. Thanks to these characteristics, construction projects using Steel Phi 12 can have a relatively long lifespan of 15-20 years.

Characteristics of Steel Phi 12:

Having understood the basic concept of Steel Phi 12, in the following section, we will elaborate on its features and properties. Specifically, as follows:

Steel Phi 12 has a diameter of 12mm and appears in the form of round steel bars with vertical lines running around its exterior, which is why it is also referred to as ribbed steel bars. This design greatly contributes to the adhesion and durability of reinforced concrete.

Moreover, Steel Phi 12 has a similar coefficient of expansion to concrete. Therefore, when used in various structural constructions and exposed to high temperatures, there will be no conflicts. This characteristic is particularly suitable for the tropical climate in Vietnam, making Steel Phi 12 widely preferred in most construction projects.

Steel Phi 12 also possesses good tensile strength while concrete has high compressive strength. Combining these two characteristics enhances the ability of reinforced concrete to withstand significant force impact.

Hence, this material seems to be widely used in everyday life, especially in typical construction fields such as framing for various structures, concrete reinforcement, beam and column systems, and more.

Applications of Steel Phi 12:

With the advantages mentioned above, Steel Phi 12 is always a top choice for creating strong frames for objects or structures. It is especially used for creating frameworks or reinforcing concrete structures in both civil and industrial construction projects. Additionally, Steel Phi 12 is commonly used in major architectural works such as hydroelectric power plants, bridges, and basic constructions like residential houses.

Technical Specifications of Steel Phi 12:

How much does one Steel Phi 12 bar weigh?

Understanding the technical specifications of Steel Phi 12 can help contractors accurately calculate the required quantity for each project, which will minimize unnecessary costs and prevent wastage.

To calculate the weight of one meter of Steel Phi 12, you can use the following formula, which is similar to the calculation of other ribbed steel bars:

m = (7850 x L x 3.14 x d²) / 4


  • m: Weight of Steel Phi 12 (kg)
  • L: Length of the steel bar (m)
  • d: Diameter of Steel Phi 12 (mm)
  • 7850: Specific weight of Steel Phi 12 (kg/m³)
  • 3.14: Pi value

Most steel types currently have a standard length of 11.7 meters. Based on the above formula, the calculation for Steel Phi 12 would be m = (7850 x 11.7 x 3.14 x 0.012²) / 4 = 10.38 (kg). Therefore, the average weight of one Steel Phi 12 bar is approximately 10.38 kg.

How long is one Steel Phi 12 bar?

Most construction projects use a standard specification for steel bars, so most manufacturers of Steel Phi 12 adhere to these specified parameters. The standard length of one Steel Phi 12 bar is 11.7 meters, which is also applicable to other types of steel. This standardization allows for more convenience in transportation and handling during the purchase process.

How much does one Steel Phi 12 bar cost?

The cost is always a question that many people are concerned about. Quickly updating the price level allows customers to make informed choices and calculate the necessary expenses when purchasing. The price of Steel Phi 12 may vary depending on the manufacturer, production process, and quality.
