The site shall be provided with safety protection methods, and special personnel shall be set for fire prevention and ventilation treatment to prevent fire or personnel poisoning accidents in the process of anti-corrosion painting.In addition, during operation, the weather of the day shall be considered. If the weather is bad, construction cannot be carried out.In order to prevent the inconvenience and loss of workers in the construction process of Guiyang steel structure anti-corrosive coating, attention should be paid to the processing and manufacturing of components and the operation of the device.First of all, with regard to the general situation,It is better to use dry and easy to spray cold solid coating; secondly, in the process of component processing, manufacturing and field splicing, it is necessary to ensure the quality of the weld. Because the raw materials in the weld are messy, it is easy to form electrodes, and it is easy to rust in the heat affected area. Before coating, it is necessary to thoroughly clean the weld slag and splashes; then, the steel structure components without special treatment are strictly prohibited from soil.The soil has strong corrosiveness to steel.

The bottom strength concrete shall be used to cover the soil touch area, and the thickness of the protective layer shall be ensured to meet the requirements; meanwhile, the joint parts of steel structure components (weld joints or bolt joints) shall not be pre coated in the factory,Only after the site devices are in place, carefully arrange these parts to prevent the welding of components after coating as much as possible, so as to prevent the integrity of the coating; moreover, the components manufactured and processed in the factory shall be properly stacked to prevent the secondary coating caused by the rust on the steel surface, resulting in unnecessary waste.For the coating damaged in the process of component transportation or device, it shall be cleaned timely after the device is in place, and the coating shall be corrected according to relevant standards.Steel is the data of various shapes, sizes and functions of ingots, billets or steels processed by pressure.Steel for construction can be divided into steel for steel structure and steel for concrete structure.The steel for steel structure is mainly low alloy steel (Q345 Series) and general structural steel (Q235 Series) plates. In some important structural designs, the steel materials with Z-direction functional requirements such as z15, z25 and Z35 are required.Q235 data is mostly used for light steel main structure, Q345 data for heavy steel main structure, Q235 round steel for embedded anchor bolts, hot-rolled steel bars for braces, and a few other steel shapes such as angle steel, channel steel, H-shaped steel, etc.Civil steel mainly includes screw steel, round steel, wire rod and section steel, etc.
