Second, the engineering aspects of the handling problems

    The current form of the construction company's business, in terms of the steel works, almost always take the overall civil contract → → anti-corrosion construction steel specialist sub-specialty subcontractor, the subcontractor even then the road, so the actual coating application time simply showing everyone said "in hosting package" phenomenon, brought many negative factors for steel coating quality and safety control, common are:

    1, the total package, or some specialty steel subcontractor construction design (program), and most of them have content anticorrosive coating of fire, but in the actual construction material selection, construction and construction organization design approach (plan) requires close support large number of other packages which do not always pay attention that has been subcontracted to a specialized company, the total package does not have a person in charge of this quality and safety, steel corrosion fireproof coating is difficult to obtain useful substantive processing.

    2, more steel Contractors general contract factory production and field devices, the device also has Contractors subcontracted part alone. Steel manufacturing and installation company even has a certain scale, for the painting project is greater shot blasting and primer coating in the factory when the limited production, and on-site equipment after painting project is sub-sub. Therefore, in many conditions, the final painting on site workers, equivalent to some temporary patchwork labor force, an appropriate number of workers without necessarily paint quality and safety skills training, nor Bangdai old master, and no painting craftsmen counseling, for this situation, it is difficult to ensure the quality of painting works.

    3, a portion of the appropriate quality personnel to handle the steel rust quality specifications are not familiar with the concept of ambiguity, including craft designers will be showing the mechanical descaling specification written ST2.5 level, some believe handle mechanical descaling is craft craft rust and so on.
