Concrete vs. Steel: Which One Is Superior?

Steel Girder

There are many aspects to be considered in a construction project. Finding the best solution in terms of material and process selection is the key to obtain desired results at the end of your project.

In the article “Concrete vs. Steel: Which One Is Superior?”, we have made a comparison between concrete and structural steel by investigating the cons and pros of each of them.


Concrete: Prices of concrete do not vary a lot in time. This is a strong advantage in terms of the economical aspect. Besides, concrete material requires maintenance and repair. It causes maintenance costs throughout its lifecycle. The supply/demand ratio can have an impact on availability. Concrete is poured and used on-site, however, the curing takes longer hours which could add to labor work hours, thus costs increase.

Structural Steel: Most of the steel produced today is coming from recycling operations. Recycled materials are much cheaper compared to others. Fluctuations on the price of steels can occur but it is usually a cheaper option against concrete.


Concrete: This composite material is made out of gravel, cement, sand, and water. The compressive strength of concrete is high, but its tensile strength is very low. It must contain steel reinforcement to enhance tensile strength, elasticity, and ductility.

Structural Steel: This material has very high toughness and ductility. These properties of structural steel enable them to be utilized in serious building applications in which a high amount of loads are present.

Resistance to Fire.

Concrete: Concrete is naturally a fire-resistant material. There is no need for additional processes to make it fire-resistant. This property makes concrete compatible with International Building Codes (IBC). Many other materials used in buildings have no resistance to fire. Builders should follow all safety standards during the construction process in order to prevent undesired consequences.

Structural Steel: It is obvious that steels are non-combustible. But at extreme temperature values, the properties of steel can be disrupted. Thus, IBS mandates that structural steel components should be treated with fire-resistant coatings to increase safety levels.


Concrete: All of the elements the concrete contains are naturally occurring substances, so, they possess no harm to the environment. It can be crushed to be added into mixtures later. Landfilling of concrete can be reduced in this way.

Structural Steel: All metals including structural steels are theoretically 100% recyclable. Today, 90% of steel production consists of secondary steel production which is the production of steel from scrap. The structural integrity of steel can be preserved in long years of service with high adaptability. When produced, processed, and properly treated, structural steels will cause minimal harm to the environment.


Concrete: Constructing a building with floor-to-floor heights and open spans is problematic with concrete even if it can be molded into different shapes. Therefore, the versatility of concrete is debatable.

Structural Steel: Steel is highly adaptable to any type of application thanks to its flexible nature. In terms of strength/weight ratio, steel is far more superior to any other construction materials. Furthermore, the appearance of steel is more appealing than concrete.


Concrete: When properly cared for, steel-reinforced concretes are resistant to humidity and there will be no detrimental corrosion problems. But the builder should always know that the steel inside concrete must not come into contact with the outer environment. Otherwise, steel will surely corrode in time with exposure to air and water. 

Structural Steel: Just like every metal, structural steels might be corroded when they are exposed to water and air. Corrosion of structural components threat the safety of the whole building. Corrosion protection must be ensured by painting or coating. Also, precautions can be taken against fire when these coatings are applied.
