 1. Rust on steel structures can be divided into three types: ① Light rust: Pitting corrosion appears on the surface, and some parts develop oxide scale. ② Moderate rust: Bright red rust spots and some oxide scale cracks. ③ Heavy rust: Oxide scale peels off, and the oxide layer increases. Some thick oxide layers can cause the steel structure surface to sink. 2. The main hazards caused by rust on steel structures: ① Stainless steel structures will have reduced load-bearing capacity and affect structural stability. ② Stainless steel structures will increase maintenance costs. ③ Rust on steel structures will shorten their service life. If steel structures are not regularly maintained and treated in a timely manner, rust stains and oxide scale will increase the corrosion and rust rate of the steel structure, which will not only affect the service life of the steel structure but also create potential safety hazards. 3. Effective methods for dismantling steel structures: ① Manual rust r...

 Routine maintenance of steel structures should focus on structural safety, corrosion protection, and the maintenance of connection components. Specific measures are as follows: 1. Routine Inspection and Maintenance Inspect components such as supports and purlins for deformation, corrosion, or loosening, with particular attention to the tightness of bolted connections. ‌ The thickness of the roof insulation layer must meet standards to prevent condensation, which can cause prolonged moisture exposure and corrosion of metal components. 2. Corrosion Protection: Promptly repair areas with peeling paint or rust. Prioritize the use of anti-corrosion paint or spray coatings for protection, ensuring the metal surface is clean and dry. Maintenance of Special Components Supports and sliding ball joints: Regularly lubricate moving parts (such as sliding ball joints) using molybdenum disulfide grease to reduce the coefficient of friction and maintain smooth rotation. ‌ Check that drainage ar...
