1. Steel Is Very Flexible and Versatile Since it was first used in construction work, steel has been a very popular material when cast iron has been upgraded to carbon steel. Construction projects using steel materials have a market share of nearly 50% for the construction of apartments and other commercial buildings in America. This is due to the flexibility of steel which is very good to be formed into anything combined with other materials. Yes, really anything. This flexibility also makes steel an attractive choice for residential construction. That way, architects and designers will easily design buildings artistically without neglecting the security and toughness of the building. The strength of steel also allows this material to be used for building structures that require a large area of land, such as aircraft hangars, warehouses, indoor arenas, skyscrapers, and agricultural barns. Burj Khalifa for example, the tallest building in the world has a height of up to 829.8 meters and uses reinforced concrete in its structure as much as 31,400 metric tons.
2. Steel is Environmentally Friendly Have you ever known that steel is the most recyclable material in the world? Based on statistical data from the Institute of Scrap Recycling Industries (ISRI) in 2015, there were 73 million metric tons of old steel in the USA that were recycled in 2014. Until now, there are 80 million tons of steel that is recycled every year, so there is very little waste. . In addition, since 1990, the steel industry has reduced energy intensity per tonne of steel produced by 28% and CO2 emissions by 35% per tonne of steel shipped. In addition, the use of steel materials can reduce the threat of illegal logging to wood or forests. Wow, this steel fact is astonishing, right?
3. Steel is more economical than wood In 2002, the United States Department of Housing made a comparative study of house construction using steel materials and house construction using traditional wood materials. In the short term, steel housing construction costs 14% more than wooden housing construction. However, in the next few years, the maintenance costs of steel-based house construction will be much lower than that of maintaining wooden houses. Since then, many things have been developed so that the gap in the cost of steel construction can be equalized with the cost of making wood construction. Reported by the American Institute of Steel Construction, “In 1980, it took 10 hours of work to produce 1 ton of steel. But currently, 1 tonne of structural steel can be produced in less than an hour of work. " With the same cost, of course the benefits of steel construction will be much greater. Steel construction will clearly be more durable and does not require complicated maintenance, repair or replacement. But remember, don't buy steel with the principle of cheap origin. Mistakes in choosing building materials that do not have national standards - for example, as simple as concrete iron - can be very fatal because they tend to be less sturdy and less durable.
4. Easier Steel Structure Maintenance Yes, of course, maintenance of steel construction will be much easier and cheaper. Steel material will be more resistant to pests, rot, termites and other factors that can usually eat away at other materials such as wood and bamboo. The ability of steel construction to maintain strength is what makes buildings safer. Every building certainly has a period of wear and tear, but steel structures can last longer than structures built with other materials. Without realizing it, the damage caused by fungus and termites can actually be fatal and cost a lot of money, especially for commercial buildings such as office buildings, apartments, and real estate. If you have this, the building owner will certainly allocate a lot of costs for maintenance, repair, and replacement of damage.
5. Faster Development Time Construction that is built from steel material usually takes 20–40% faster construction time, relative to the construction site and the scale of the project. This is also related to development in areas with difficult or steep terrain. Why so? Steel for construction needs can be made according to the specifications desired by the contractor. So that when the steel has been produced by the factory, the contractor can easily assemble and install steel structures. Compared to materials such as wood and bamboo which have to be re-measured, cut and re-installed at a construction site for accuracy of construction. This is what causes construction times to be accelerated and allows the completion of large-scale projects in just a few months. Fast and timely project execution will certainly facilitate business activities, so that the emergence of other unexpected costs can be reduced.
6. Steel is Stronger and More Durable The strength and attractiveness in carbon steel makes steel construction better able to withstand a variety of weather and conditions such as strong winds, blizzards, fires, floods and seismic activities such as earthquakes. Naturally, the nature of carbon steel is indeed more resistant to natural disasters. In the case of fire, for example, damage can be minimized because steel has fire-resistant properties. So it is certain that the fire will spread more slowly in steel construction than in other materials such as plastic, wood, or bamboo. In the case of earthquakes, steel has a better tensile strength than other materials so it is more flexible. Therefore, when an earthquake or shock occurs, steel structures are better able to withstand buildings and minimize damage. Similar to wind resistance, the flexible nature of the steel structure makes it able to withstand strong winds well. For this reason, the production of steel has been closely monitored for decades to ensure the quality of steel that is strong, safe, and refractory.
7.Strength to Weight Ratio (Lighter Than Wood) If you weigh 3 × 5 wood with 3 × 5 steel, which one is heavier? Of course steel will be heavier because of its density. However, when discussing the matter of framing, however, the design of the steel beams used will be lighter than the design of structural wood beams. The American Institute of Steel Construction has stated that structural steel not only has better strength, but also has a much higher strength-to-weight ratio than other materials. This makes the building structure lighter, so the manufacturing costs will be cheaper. This is also supported by a statement from the American Iron & Steel Institute which states that among all the materials that have been used in construction projects, steel is the material with the best strength to weight ratio. That way, the steel components used will be stronger even though they don't add much weight. The advantages of this lightweight steel construction can save labor, shipping costs, simplify the design of the building foundation, and of course reduce the project budget.Read More >
What Is Iron? Based on the KBBI (Big Indonesian Dictionary), iron is a metal that is hard and strong and has many uses (as a material for making weapons, machines, etc.). Iron is an element that exists in abundance every place on our planet and is relatively well known for its properties and uses. Iron is not found purely in nature, but is mixed with various other materials.
Various iron alloys are made to be used as raw materials in the application of civil engineering in the field of building structure construction. In biology, iron is also widely contained in food ingredients and has an important function in supporting human health. We can find various types of iron in our daily life at this time. The types of iron that are very commonly used in everyday life are tools and tools made of wrought iron. Wrought iron is an iron alloy consisting of a mixture of iron and silicates.
Cast iron generally has a very low carbon content. The next type of iron that is often found in our daily lives is pig iron or crude iron. This pig iron has a carbon content of between 3.8 to 4.7%. This pig iron will later be processed into wrought iron, also known as cast iron and steel.
What is Steel? Steel is the development of the use of iron which is widely used on this earth. Steel is an alloy of iron and carbon, and sometimes other elements. Due to its high tensile strength and low manufacturing costs, steel is a major component used in the construction of buildings, infrastructure, tools, ships, automobiles, machinery, tools and weapons.
Steel differs from iron in that it is an alloy or an alloy and is not an isolated element like iron. Alloys are mixtures of various metals or metals mixed with other elements. Steel is made by mixing a small percentage of carbon with iron. Carbon content usually does not exceed 2.1% by weight. The presence of Carbon provides strength to the steel and makes it more suitable for various uses. The higher the carbon content used in steel making, the more brittle it is. Steel also has other alloying elements such as chromium, nickel, and manganese. These elements are added to make the steel more resistant to rust.
That's why the steel surface stays shiny for longer. Steel is used throughout road construction, for the manufacture of railways and railways, various home appliances as well as in the construction of buildings and bridges. Famous examples are those listed at the beginning of this article: the Eiffel Tower and the London Bridge. Iron processing and steel processing have been carried out since ancient times. Iron and steel cannot be separated from the history of human civilization. Various tools and equipment for life and warfare were made by humans from iron as well as from steel.
