Material Preparation: Select appropriate steel, usually high-strength low-alloy steel, and cut and prepare it according to design requirements.
Welding Assembly: Weld the steel plates and steel beams into the basic framework of the main beam. This process requires ensuring the quality of the welds to guarantee the strength and stability of the main beam.
Correction and Straightening: After welding, the main beam may deform, so correction and straightening are needed to ensure the straightness and geometric dimensions of the main beam meet design requirements.
Machining: Perform necessary machining on the main beam, such as drilling holes and making slots, to facilitate the installation of other components.
Sandblasting and Anti-corrosion Treatment: Conduct sandblasting on the surface of the main beam to remove impurities and then apply anti-corrosion treatment to protect it from rust and corrosion.
