Steel Bar

Plain iron or plain bar is iron that has a round cross section with a smooth or finned surface. In contrast to screwed iron or deformed bar, it is iron with a fin-shaped surface with transverse directions which are formed by twisting or in the form of elongated ribs with a certain pattern. This deformed bar is specially designed with a given motif to function as a better mechanical retainer for the construction of buildings and buildings.

Concrete itself is a mixture consisting of several building materials, namely plain iron / plain bar or it can also be deformed iron / deformed bar which is combined with gravel or crushed stone, sand, cement, and water. These ingredients will be mixed and then kneaded into a dough and when dry will form a mass that resembles a very hard rock. This bar is often used and serves as a load-bearing. Concrete mixture must be given a framework made of plain bar arrangement or it can also use deformed bars. In addition, this framework also functions as a concrete barrier so that it does not shift.

Reinforced concrete containing plain iron / plain bar or also deformed iron bar which is united with gravel or crushed stone, sand, cement and water is designed based on the assumption that these materials will work together to lift the load of the building. Reinforced concrete has a unique property where these two types of materials, namely reinforcing steel and concrete are used together.
