Steel column docking requires precise positioning and angles. During the construction process, measuring tools and markers are used to locate and mark the steel columns to ensure the docking position and angle, as well as the stability and safety of the structure. Preheating treatment is also required for welding of important components, alloy steel, and thick parts, which places higher demands on the speed of docking and welding.
