Super Lowest Price Carbon Spring Steel - I-beam Structural steel online purchase – Lu
Introduction I-beam, also known as steel beam (English name Universal Beam), is a long steel with an I-shaped cross section. I-beams are divided into ordinary I-beams and light I-beams. It is an I-shaped section of steel. Regardless of whether the I-shaped steel is ordinary or light, because the cross-section size is relatively high and narrow, the moment of inertia of the two main axes of the cross-section is quite different, so it can only be directly used for bending in the plane of its we... -
