The "fire resistance design" of steel structure is to resist fire and resist gravity, resist wind load, resist earthquake action on the same level, by taking fire protection measures for structural components, in short, "fire resistance design" can be summed up as the design of "structural fire protection" protection measures, so that the components under the external load conditions to meet the "structural fire resistance" time requirements. These requirements are the basis of steel structure fire protection design specifications.
Steel structure, H-shaped steel, channel steel
Steel structure fire retardant coating, according to the thickness is divided into three categories: 1. Ultra-thin steel structure fire retardant coating, coating thickness is less than or equal to 3 mm;
2. Thin-coated steel structure fireproof coating, coating thickness is greater than 3 mm, and less than or equal to 7 mm; Thick-coated fire-resistant coatings for steel structures with a coating thickness greater than 7 mm and less than or equal to 45 mm.
