Translation: Heat resistance, freeze-thaw resistance, salt fog corrosion resistance, and UV radiation resistance: the coating should not exhibit any peeling, detachment, hollowing, cracking or other phenomena within the specified test time and according to the specified requirements. Additionally, the thermal insulation efficiency decay should be ≤35%.
Moisture resistance, acid resistance, and alkali resistance: the coating should not exhibit any peeling, detachment phenomena within the specified test time, and the thermal insulation efficiency decay should be ≤35%.
The fire resistance of steel structure fireproof coatings should conform to the requirements of GB/T14907.
Steel structures have many advantages. Steel is a non-combustible building material that has seismic resistance, bending resistance, and other characteristics. In practical applications, steel can increase the load capacity of buildings and meet the aesthetic and design needs. It also avoids the shortcomings of traditional building materials like concrete, such as inability to bend or stretch. Therefore, steel is widely used in the construction industry, from single-story buildings to multi-story buildings, skyscrapers, factories, warehouses, waiting rooms, and airports.
