Steel fabrication involves the process of transforming raw steel materials into pre-engineered components used for constructing various structures. Drilling is a fundamental step in steel fabrication, allowing the creation of holes to accommodate fasteners and connections necessary for assembling steel structures. Special considerations are made for drilling through steel, including tool selection, coolant or lubrication usage, and the use of drill presses or CNC machines for precision. The drilling process plays a crucial role in ensuring the efficiency and stability of the steel structures during construction and assembly.
