They can be used for crane beams and work platform beams in factories, floor beams in multi-story buildings, purlins in roof structures, etc. Steel beams are generally divided into section steel beams and composite beams. Section steel beams include I-beams or channel steels formed by hot rolling. Light beams such as purlins can also use cold-bent Z-shaped steel and channel steel. Composite beams are welded or riveted by steel plates or section steels. Before the steel beams are put into use, they need to be polished to remove rust on the surface. Currently, they are often polished manually with handheld grinders, which is time-consuming and labor-intensive. Especially for I-beams, which have an I-shaped cross-section, it is more difficult to manually polish the sides of the I-beams, and the rust produced by grinding needs to be cleaned later, resulting in low work efficiency.
