The performance of steel structure production quality that does not meet the requirements

1. Cutting and slitting

When cutting and blanking, the size of the flange plate is different, which causes the size of the H-beam and the corbel to be inconsistent. The upper and lower flange plates of the steel beam connected with the corbel are misaligned by about one plate thickness; the cutting edge has a deep cut , The edge of the board has obvious depressions, or has a deep serrated mark, the cutting roughness exceeds the standard, the cutting edge of the panel is not perpendicular, and the splicing of the wrong edge exceeds the standard.
