Difference between Nako Iron and Concrete Iron: Don't Use It Wrongly

In the construction world, selecting the right steel material significantly impacts the strength, safety, and lifespan of a building. Two types of steel that are often misunderstood are rebar and reinforced concrete. Although both are made from steel, they have very different functions and characteristics.

To avoid fatal errors in the field, here is a complete explanation of the differences between rebar and reinforced concrete.

Definition of Rebar
Rebar is a square or rectangular steel bar with specific dimensions. This steel generally has a solid and neat appearance, making it often used for visually visible elements.

Characteristics of Rebar

• Square or rectangular shape
• Smooth and precise surface
• Strong with light pressure
• More aesthetically pleasing

Definition of Rebar
Rebar is a round steel bar specifically designed as reinforcement in reinforced concrete structures. This steel is available in two main types: plain rebar and deformed rebar.

Characteristics of Reinforcing Steel

• Round shape (plain or threaded)
• Designed to withstand tensile forces
• Used in concrete
• Meets SNI standards for structures

Differences between Reinforcing Steel and Reinforcing Steel

Comparison Aspect	Nako Steel	Reinforcing Steel (Rebar)
Shape	Square / rectangular	Round
Main Function	Non-structural & aesthetic element	Concrete reinforcement
Application Position	Visible (fences, grilles)	Embedded inside concrete
Structural Strength	Limited	Very strong (main structure)
SNI Standard	Not mandatory for structure	Mandatory for construction

Functions of Reinforcing Steel in Construction
Reinforcing steel is generally used for:

• Home and building fences
• Window and door trellises
• Stair railings
• Ornaments and decorative elements
• Reinforcing steel is not designed to support the main structural loads of a building.

The Function of Reinforced Concrete in Building Structures
Reinforced concrete plays a vital role in:

• Building foundations
• Columns and beams
• Concrete floor slabs and roofs
• The structure of houses, buildings, and bridges

Reinforced concrete works together with concrete to resist tensile and compressive forces, ensuring a strong and safe building.

Risks of Using Reinforced Concrete and Reinforced Concrete Incorrectly
Incorrect use can result in:

• Weakening of the building structure
• Cracking or collapse of the concrete
• Buildings that do not meet safety standards
• Loss of repair costs later on
• Reinforced concrete should not replace rebar for structures.

Conclusion

• The main differences between rebar and rebar lie in their form, function, and structural strength.
• Reinforced concrete is suitable for both visual and non-structural elements.
• Reinforced concrete is mandatory for load-bearing building structures.

Understanding these differences is crucial for ensuring construction projects are safe, strong, and meet standards.
