Steel structure is easy to corrode



Steel structure must pay attention to protection, especially thin-walled components, therefore, in a strong corrosive medium within the building should not use steel structure. Steel should be thoroughly rusted before painting, paint quality and coating thickness should meet the relevant regulatory requirements. In the design should avoid the structure of moisture, leakage, the structure should be avoided in the inspection, maintenance of the dead ends. Newly built steel structure is generally separated from time to time to re-paint, maintenance costs higher. At home and abroad are developing a variety of high-performance coatings and corrosion-resistant weathering steel, steel corrosion resistance is poor problem is expected to be resolved.
