Problems solved by technology

However, the corrosion resistance of steel is poor, and protective measures must be taken to prevent steel from corroding and rusting, so as to ensure the safety of the steel structure during the design service period.
Outdoor steel structures are used in harsh environments, and ordinary anti-corrosion coatings are difficult to meet the requirements of high temperature and high humidity resistance, acid rain resistance, and salt spray resistance
