Steel erection is the process of assembling and installing steel structures, such as beams, columns, and trusses, to create the framework of buildings and other constructions. This work is typically performed by specialized contractors who use cranes and other equipment to lift and position the steel components accurately. The process involves careful planning and coordination to ensure safety and structural integrity. Workers follow engineering drawings and specifications to connect the steel pieces using bolts, welds, or other fastening methods. Proper safety measures are essential, as the work often takes place at significant heights and involves heavy materials.
