The prerequisite for all commodities not to have problems in application is processing. Therefore, steel structure can be widely used today because the whole production process of structure is careful and meticulous, and in the case of processing, corrosion prevention work is generally carried out to ensure that the structure is not easy to be eroded in the future application. At this stage, the structure is under construction.The common anti-corrosion method is to brush anti-corrosion materials. What are the common anti-corrosion coatings?

        1、 For the bridge steel structure, the epoxy resin zinc rich primer is generally selected, the intermediate paint is epoxy resin micaceous iron intermediate paint, and the paint is acrylate polyurethane topcoat.The advantage of this kind of paint is that the anti-corrosion range is relatively large, and the thickness of the paint can be determined according to the landform standard, so as to increase the anti-corrosion period of steel members.

     2、 For steel structure workshop components, the top coat is epoxy resin anti-corrosion top coat, the intermediate paint is epoxy resin micaceous iron intermediate paint, and the paint is epoxy resin zinc rich paint.According to the application characteristics of the industrial workshop, for example, the general industrial products manufacturing industrial workshop is different from the chemical industrial factory building, and the general industrial workshop paint is generally three times.For the steel structure workshop in extreme natural environment, it is necessary to improve the thickness of anti-corrosion paint.

     3、 For the non-standard steel components, the spray painting is generally carried out according to the engineering drawing notes. Before the construction drawing design, the planning institute should select the anti-corrosion method according to the local climate conditions.

    Generally speaking, the common anti-corrosion materials in the construction of steel structure, in fact, want to construct in the case of processing to achieve excellent anti-corrosion actual effect, in addition to the attention in the case of selection, the thickness of architectural coating is also certain provisions, because if the coating thickness is thin or uneven, it will immediately cause a variety of problems, harm In all normal anti-corrosion work, so we must pay attention to the way and process in the case of brush coating, so as to ensure that the architectural coating can help the structure to carry out anti-corrosion very well.
