Corrosion Protection Processes and Quality Control for Steel Structures

图片
 Corrosion Protection Process for Steel Structures Corrosion protection processes for steel structures are essential for ensuring that steel structures remain in good condition over the long term. This article provides a detailed overview of the various steps involved in these processes, including surface preparation, priming, coating application, quality control, and final inspection and acceptance. Surface treatment Surface preparation is the first step in the corrosion protection process. Its primary purpose is to remove dirt, grease, rust, and other contaminants from the surface of steel structures to improve coating adhesion and corrosion protection. Surface preparation includes the following steps: Cleaning: Removing grease, dirt, and dust from the surface of steel structures using solvents or detergents. Degreasing: Removing grease and wax-like substances with an alkaline degreaser to improve coating adhesion. Rust Removal: Removing rust and other corrosion products from the...

Application of space frames to hangars

图片
To date, space frame structures have been widely used in China, with application scenarios including but not limited to: industrial plants, coal storage structures, hangars, airport terminals, high speed rail stations and large stadiums. 💚💚💚 Hangars require a large span and space sufficient for aircraft parking, but also a certain load-bearing capacity to withstand the loads brought by the equipment during aircraft maintenance. In order to increase the load-bearing capacity, the construction of hangar structures has been accompanied by improvements and innovations to the traditional two-storey space frame structure. For example, the four-bay hangar at Beijing Capital Airport, built in 1996, has a three-storey space frame structure with dimensions of (153+153)m × 90 m. The hangar of China Southern Airlines at Beijing Daxing International Airport, built in 2019, has a W-shaped truss + space frame structure system with a span of 222 m at the opening side of the gate. hangar
