Functions, Classification, and Light Steel Trends ! The term steel no longer be foreign to you. This thing is pretty well known, especially among contractors or those struggling with heavy objects and development. This thing needs to be sufficient material. It's all about the advantages possessed by steel. What is steel ? Steel is a metal alloy. Steel known to be very strong and has a long durability. Steel production in addition to construction materials and the manufacturing industry is used also for agricultural implements, such as hoes, sickles and equipment agricultural / plantation.
In the old days, maybe we only know the category of heavy steel. Not anymore, with a high level of technology can be produced mild steel is used as the roof (the roof) houses, buildings. There is also built like a steel coil springs. Steel is a metal alloy of iron with carbon as the base material. Carbon makes steel hard and Crystallized (crystal lattice). Carbon content in the steel between 0.2% to 2.1%. In addition there are carbon titanium, chromium (Cr), nickel, vanadium, cobalt, and tungsten (tungsten).
Thanks to this combination of metal elements that make steel resistant to pressure and traction (hardness-tensile strength). and ductile and malleable properties (brittle and ductility).
Composition Classification of Steel
There are some who are in steel composition, are as follows.

Composition Classification of Steel
There are some who are in steel composition, are as follows.
- Carbon steel
- Low alloy steel
- Kara-resistant steel
Steel Products - Simple overview of the steelmaking process consists of an open steel furnace, electric furnace, and the oxidation of the base. Meanwhile, in the manufacture of products that can be produced from steel, these include the following.
- Plates bars
- Tube
- Sheet
- Tape
- Structural
- Ferritic
- Pearlitic
- Martensitic
- Austenitic
- Iron Concrete
- Welded Beam
- Wire Mesh
- Equal Angles
- Hot Rolled Coil / Plate
- Cold Rolled Coil / Sheet
- Wire Rod

Steel Industry Overview Info
Friends, in Indonesia, the steel has a strategic position as an industrial state. The following is a brief info about the world's steel, are as follows.
Friends, in Indonesia, the steel has a strategic position as an industrial state. The following is a brief info about the world's steel, are as follows.
- Strategic steel industry in Southeast Asia.
- Vice Regent of Badung, I Ketut Sudikerta said the iron and steel industry plays an important role.
- The steel industry is hampered scarcity of raw materials.
- Iranian steel production increase since May 2012. Iran increased its steel production to 48 million tonnes. Iran is the center of the steel industry and Kouzestan Isfahan.
- Spring steel as a whole be classified into two, namely low alloy steel and high carbon steel.
- Regulation No. Permenkeu 23/PMK.011/2011, Imposition of Antidumping Duty on Import of Hot Rolled Coil (hot rolled steel) from the Republic of Korea and Malaysia disrupt the performance of the national steel industry.
- Steel prices rising, house prices will rise. Iron staples to build a house.
- Calling President Director of PT Krakatau Steel Tbk to the Commission the Commission as a witness.

PT Krakatau Steel
Friends, it feels incomplete without including steel when talking about state-owned steel company Krakatau Steel. PT Krakatau Steel Cilegon located in Banten stood August 31, 1970. The resulting steel products, such as hot rolled steel, cold rolled steel, and steel wire rod. How PT Krakatau Steel to make steel starting from the iron ore reduction process with natural gas. Based on the results of such reduction, dihasilkanlah sponge iron which is then smelted with scrap iron-steel billet. The technology used is called an electric arc kitchen. Steel billets are sold to consumers generally wire rod. PT Krakatau Steel (Persero) Tbk currently has six production facilities.
PT Krakatau Steel to produce the processed mixed iron scrap, Bricket hot iron and other materials that will produce two types of steel slab and steel billet. Steel slab will be the end product of hot rolled steel. Usually used as vessels, pipes, buildings, general construction. The results sheet steel heat through a chemical process could still be processed into cold rolled steel that can be used for the manufacture of motor vehicle parts, household appliances, and so on. Thus, there can be no remains of processed steel. Other products produced by Krakatau Steel is a steel billet useful for nuts and bolts, steel wire, spring piano strings, and more.
Meanwhile, steel wire rod products used for infrastructure development centers Steam Power Plant 400 MW, Water Purification Centre, Port, and Telecommunications.
Light Steel Trends (Blue Steel)
Mild steel may be currently on the rise. Because the price of the more expensive wood, as well as iron prices. Formerly the roofs of houses are using wood as a buffer to install tile (roof). Now replaced by a lightweight steel frame is stronger, and the price is affordable. Mild steel products are widely spread in the market with various brands and quality. In addition, mild steel products when we order it granted a 5 year warranty for installation. This is one reason why many people are ultimately interested in choosing a lightweight steel roof as a buffer.
Not because of the trend alone, a home that uses a buffer of lightweight steel roof can shed water more easily and quickly, and leakage. Trends mild steel was originally used for luxury homes and buildings. Now, ordinary houses too many have been using mild steel, among schools. In short, almost all the buildings that had been used as a buffer timber roofing tiles, zinc. Has now shifted to mild steel.
Then suddenly among friends who are interested to do business self steel. It's OK. Steel does not always seem "heavy" especially steel roofing and sheet steel, and steel is used for the domestic industry. Stainless steel. So open wide opportunities to sell steel products.
