What does the number after the H-beam represent?



H-beam is an economic cross-section profile with more optimized cross-sectional area distribution and more reasonable strength to weight ratio, named after its section being the same as the English letter ' H ' . Due to the fact that all parts of H-beam are arranged at right angles, H-beam has advantages such as strong bending resistance, simple construction, cost savings, and light structural weight in all directions, and has been widely used. The H-beam section often appears with symbols similar to H480 below × two hundred × eight × 14. It is difficult for friends who have not come into contact with steel structures to understand the meaning of the following numbers. Today, I will explain to you the meanings they represent.



H-shaped steel



H:Represents H-shaped steel



480:represents the total height=100% of the section steel



200:represents the total width=100%



8:Indicates the thickness of the web plate



14:Indicates the thickness of the flange




The first two numbers above refer to the total height=100% and width=100%, while the total width=100% refers to the length of the flange. For example, H350x175x7x11 represents the height=100% of H-shaped steel 350mm, flange width=100% 175mm, web thickness 7mm, and flange thickness 11mm.
