Iron Canal C CNP and UNP are the main steel materials normally used in Indonesia based on construction requirements. This type of construction material already meets the construction standard so it is highly recommended as construction material. As we all know, the construction needed, especially in Indonesia itself, is a solid and permanent construction. In addition, the quality of construction is also a top priority.
In addition to UNP iron, there are several other steel materials that are also commonly used in Indonesia. Materials such as wide flanges (WF), c channels (rectangular hollow section) - cold formed (hollow square) shs (square hollow section) - cold formed (hollow box) steel pipe , black pipe, galvanized pipe, seamless pipe, welded pipe).
WF Iron itself is usually used for beams, columns, piles, top & bottom chord member on truss, composite beam or column, cantilever canopy, and others. There are other terms for this iron that is IWF, WF, H-Beam, UB, UC, beam H, beam I, and beam W. For the use of iron UNP alone is almost the same as WF. It's just for the columns are rarely used because iron type UNP relatively easier. Other names of this type of iron are U Channel, U-channel and U Profile.
