The difference between I-beam and H steel is that a steel structure platform for cast iron machine should be designed. Cast iron captain 30 meters, every two meters with an upright column, which steel to choose?The web is much higher than the flange and is mainly used for bending.H steel: Web and flange are highly close. Used for bending members.The column is preferentially made of section h steel.
The flange of the I-beam is variable cross section, the thickness of the web is thin and the outside is thin. The flange of H section steel is equal sectionHW HM HN H is a general term for H steel, H is welded, and HW HM HN is hot rolledHW is a H type steel flange height and width substantially equal; mainly used for reinforced concrete frame column steel column, also known as rigid steel column; column is mainly used in steel structureHM is of H steel, and the width and flange width ratio is approximately 1.33~~1.75, mainly in the steel structure: used as steel frame columns, used as frame beams in frame structures subjected to dynamic loads; for example: equipment platformHN is H steel with a flange width ratio greater than or equal to 2, mainly used for beams; the use of I-beam is equivalent to that of HN;It's safer to use column H if it is used as upright post. I-beam is generally used as steel beam.
The I-beam wing plate size is smaller than H steel. The general structure of H steel beam column, I-beam, reason is the design of column not only bear the vertical downward force, but also bear a certain horizontal force, to increase stability of the structure in the horizontal direction. Beams generally withstand only vertical downward pressure.
