Product Description

Standard:GB,ASTM,EN,JIS

I-beam also known as Universal Beam, is a cross-section of the shape of the long steel bar. Is the cross-sectional shape of the font type of steel.I-beam steel flange from the root to the edge of the gradual thinning, there is a certain angle

Application Scope

As the cross-sectional size are relatively high, narrow, so the cross-section of the two main sleeve of the moment of inertia difference is large, which makes it in the scope of application has a great limitation. The use of I-beam should be selected according to the requirements of the design drawings.
I-beam is widely used in a variety of building structures, bridges, vehicles, stents, machinery and so on.
