Iron-concrete is one of the building's concrete-forming material. The quality and quantity of iron-concrete used is directly proportional to the dimensions of the concrete.As a result the greater dimensions of the concrete, the concrete size and amount of iron that is used is also getting bigger.

Concrete iron became a very important building material. Iron bone it will be concrete strut construction of the building.Therefore iron concrete must have a size based on the location and construction of the building. For example if the layout of the building at the roadside, we recommend that you use the larger iron size. It aims to make iron bars can withstand vibration when there is a passing vehicle.Then when the soil surface is a type of loose soil for example former rice field soils or soils that are easy iron then crabbed landslide will be indispensable.

Then the construction of the building was also largely determine the size of the iron-concrete is required. Iron is necessary for simple one-story house is certainly different from terraced houses. If building the necessary iron, usually have larger sizes and require a crabbed.As for the ordinary building which is only one-storey iron required could be smaller and does not require a crabbed.

Types of concrete iron commonly sold in the building is called the iron bars and iron so it fits the size and usefulness.For buildings that require large size iron iron bars should use as it can be assembled on its own customized building but the drawback is longer in normal use.While for simple buildings could use the iron so that the iron is already formed and ready to use for example chicken claw, pole so, iron sluf and so on.The benefits work faster because it does not need any more but the drawback of arranging the size of the iron is relatively small or standard.
