JIS G3101 SS490 I-beam

JIS G3101 SS490 I-beam can be manufactured as ordinary steel or light, since the cross-sectional dimensions are relatively high, narrow, the cross-sectional moment of inertia of the spindle have larger difference between two. JIS G3101 SS490 I-beam can only be directly used in its web plane flexural member or its constituent lattice force member. For axial compression members or perpendicular to the plane of the web as well as curved components are not appropriate, it makes steel SS490 I-beam on the scope of application has a lot of limitations. SS490 I-beam is mainly used in various building structures, bridges, vehicle bracket machinery.

JIS G3101 SS490 Angle steel chemical composition:  

JIS G3101 SS490 Angle steel mechanical property :

SS490 I-beam Advantages:

1. The flange width and lateral stiffness
JIS G3101SS490 wide-flange beam aspect ratio is up to 1 and slightly less than 1, a significant increase in its stiffness around the weak axis can be more reasonable when used for compression members, with narrow flange series Yijiao high beam flange width 1.1 to 1.4 times, JIS G3101 SS490 I-beam is in cross-sectional area under the same conditions, and weak shaft stiffness is more than 1 greater times or 1 times.

2. The two flange surfaces parallel to each other, to facilitate construction
SS490 wide flange beam and two surfaces parallel to each other, thus become more convenient and easy.

3. processed regeneration profiles
SS490 I beam can be more easily processed into a T-shaped steel beams and honey comb.
