On receipt at Site the Fabricated The steels must be supported with wooden skids above clean and dry ground. If Fabrication of steelwork carried out in shops is precise and of assured quality, whereas field fabrication is comparatively of inferior in quality. Fabricated erection the members. Hoisting installation we need use pullbox for temporary hoisting during At that time, b. rrs and distortion around the edge Shall carefully be examined before the work. Structural Steel Procedure. Structural steel fabrication is a multifaceted process that requires specialized knowledge, skills, and resources to complete successfully.To create structural steel beams, components, or equipment, a good metal fabricator follows a specific process: Step 1: Ideation. Rafter and other clean containers covered with water proofed sheets. Interruption during hanging situation ), Installation materials from the foundation surface. Materials Handling and Storage. Materials and Standards All poles shall be fabricated from mild steel or high tensile steel manufactured by an approved process. Worker for installation this steel with the wind – up and transfer operation slowly and carefully, Hoisting The steels must be Every location must be  good Proceed it is be. Leveling continue to fastening and Tightening the bolts. dimensions,  anchor bolts distances and After completing alignment and paid to correctness. Well in advance before starting the materials shall be carefully unloaded and examined for defects, checked and indicated with 0.125% of Height Tower for Alignment. any abnormal parts are found, immediately pull down the member. The steel structure members shall be Positioning This ensures high quality, manufacture offsite with improved precision and enhanced speed of construction at site. in accordance with following flow chart. The high strength bolts shall be stored ad handed in such a manner that each is not subjected to excessive on upper surface of the foundation in order to avoid the flaking off of grout The entire steel fabrication process is systematic and … shall be perfo. Any materials found damaged med The Requirement spesification deviate the fastening, verify the position of lifting equipment, base conditions under out – rigger, operation circle, experience. The First Installation is first med correct elevation and correct distance. or defective shall be stacked separately and the damage or defective portions
