Increasingly rampant illegal logging as well as large-scale and not environmentally friendly makes various industrial products flocked to produce new innovations. One that produces new products is a construction company or building material. Along with the emergence of the concept of environmentally friendly development which emphasizes increasing efficiency in using water, building materials, and energy, starting from the construction, design, to the maintenance of the building going forward.
The light steel frame has now begun to replace wood which incidentally from the past until now is used for a framework on the main building and also the roof of the house. As a result of illegal logging makes the building with wood raw materials began to decrease, this is a form of concern for the environment and preserving the earth. So now wood has begun to be replaced with mild steel.
Mild steel itself can be chosen based on its level of quality and depends on the raw material itself. Its own advantages from the roof truss and also the building truss is the material that is porous, stronger, rust-resistant, termite resistant, easy to install, flexible, and also lighter, so it will not burden the foundation and also the construction of the building, but it can also be easily installed based on architectural calculations and with civil engineering calculations.
Nowadays mild steel material is becoming a trend in itself as a building material, the light steel roof truss is more popular compared to other steel materials. This is due to the incessant advertising of lightweight steel roof truss that replaces the wooden frame, which incidentally has always been the main building material. In addition, nowadays wood frames are increasingly expensive, so using lightweight steel frames is an alternative to wooden frames.
Time efficiency in the installation process is also one of the reasons today many uses lightweight steel frames, easy installation is also one of the reasons underlying the use of mild steel is now increasingly popular. Good mild steel products have environmentally friendly properties, this is due to using materials that are also environmentally friendly and can reduce the rampant illegal logging.
Steel and type
Steel is a metal alloy whose main components are iron, and carbon as its main alloying material. Carbon functions as a hardener, preventing iron atoms, which themselves are regular in the and shift between one another. Steel with increasing amounts of carbon will be able to harden and strengthen iron, but will also be more fragile.
History of Steel
Since ancient Egypt, in the year 3000 BC metal smelting techniques have existed, even the manufacture of iron jewelry has existed from previous times. The process of hardening the iron using heating treatment began to be introduced in the manufacture of weapons in 4000 BC in Greek times.
Wrought iron is an integrated process made from the 14th century. This process is done by heating iron ore and charcoal into a furnace. Sometimes what is produced from this process is steel instead of wrought iron. And gradually these wrought iron makers learned to be able to make steel.
Types of Steel
Steel is classified into three parts, namely:
• Stainless Steel
Or stainless steel is a type of steel that has good resistance to heat, rust, scratches, or friction. This type of steel is also a type of steel that is resistant to high and low temperatures. Besides this type of steel is also strong and can be forged.
• Carbon steel
Carbon steel can be divided into three types, namely high carbon steel, medium carbon steel, and low carbon steel.
Strengths and Weaknesses of Steel Construction
Steel has its own advantages, namely strong. When viewed from its strength steel tends to be stronger and durable, steel also has anti-rust, termite-proof, and also porous properties so that steel material is very popular for the construction of building frames. But steel also has other properties, namely bending, so that if the steel experiences pressure on one side it will experience a curve.
The flexible nature of the steel will not make the steel crack like it is glass, but gradually the steel will come out of shape and bend. And because the pressure is too high from one side will make the steel construction will be damaged. So that existing residents must evacuate to keep themselves safe from the danger of collapse of a building or house. However, the use of steel as a building frame rarely fails suddenly broken, if not caused by seismic forces or earthquakes.
Steel Construction Has Advantages
Each section has been prepared at the factory, so the only activity carried out while in the field is to install the prepared construction section. So the time needed for installation is relatively faster and shorter. Steel is more resistant to extreme weather changes, stronger, and also not easily porous. The type and size of steel can adjust to the construction to be built later and is also available in a variety of variations. If later the building is demolished, the steel frame can still be used and resold for profit or can also be used for other construction purposes. The connection process can also be done in various ways that can be forged, welded, and so on.
Weaknesses of Steel Construction
Components in the structure of steel must be adjusted so that they can withstand fire to protect against fire hazards. Need additional costs for steel maintenance in order to be resistant to rust. Because of the flexible nature of the steel, the steel cannot withstand the pressure because it will later come out of shape and experience a curve.
