How to prevent steel structure engineering rust?

Steel structure engineering is easy to be corroded in high humidity and corrosive medium. The common antirust method in steel structure engineering is to coat the steel surface with non-metallic coating to maintain the steel. Steel structure engineering coating has two kinds of primer and topcoat. Before painting, be sure to remove burrs, rust, oil stains and attachments from the steel surface. There are three commonly used derusting methods in steel structure engineering: manual derusting, pickling and sand blasting. The construction method of coating has two kinds: brush coating method and spraying method. In the construction process, should grasp the appropriate coating thickness and layer number, as well as good weather conditions and temperature conditions. In some specific conditions, steel structure engineering is particularly easy to corrosion and rust in the presence of degenerate medium. It must be painted or galvanized regularly during use.

Steel structure derusting and painting project. The rust removal and coating of steel structure are the links which are easily neglected in the steel structure project at present. The derusting of steel structure is divided into manual derusting and mechanical derusting. The construction personnel adopt different derusting methods according to the requirements of drawings and derusting grades. The quality control of the coating project should be carried out before the coating, and the surface of the component after the coating should be free of welding slag, oil, water, burr and other foreign bodies, and the coating frequency and thickness should meet the design requirements. Paint certificate, paint project by the fire department approved by the construction unit construction.
