Structural I-Beam Structural I-Beam Structural I-Beam

Structural I-beam, also called steel beam, is a long product with I section. This product is widely used in building structures, bridges, vehicles, brackets and machinery, etc. There are three types of this product, ordinary type, light type and H-shaped type. Because sectional dimensions of both ordinary type and light type are relatively higher and narrower, difference of moment of inertia for two main shafts is too big. The standard is GB/T 706-2008 and materials are Q235B and Q345B.
