Nowadays, important facilities and equipment using steel structure as the main body are playing more and more important roles in various fields. In order to use the steel structure more widely and safely, the corrosion problem of the steel structure and its connecting parts needs to be solved. The petrolatum tape covering(PTC) technology and oxidizable tape covering(OTC) technology are useful methods to improve the corrosion resistance of steel structure. The PTC technology applys to steel structures in zones with harsh corrosion environment(such as the splash zone), while the OTC technology applys to steel structures with special shapes in atmospheric zone. This paper introduced the corrosion problems of special-shaped steel structures in the splash zone and atmospheric zone, putted forward the solution of wrapping anti-corrosion technology, and then summarized the practical application of wrapping anti-corrosion technology in steel structure engineering and its protection effect. With the continuous improvement of relevant technologies and industries, the PTC and OTC wrapping anti-corrosion technologies would play more important roles in more fields, contribute to marine power and promote high-quality development.
