Steel structures most often have to be protected where production is already running: in workshops, warehouses and on the pipe racks of operating plants and power facilities. Shutting a plant down for painting is usually not an option, so the work is built around the client’s process. Here is how we organise it and what is worth agreeing before we start.
Fire protection of steel structures works only when the coating is intact and has the required thickness over the entire surface. In practice the coating gets damaged far more often than it seems: installation work on site continues for months after painting. Here is how to tell whether a local repair is enough or the coating has to be removed completely.
Fire resistance of unprotected metal structures. This concept is crucial when assessing the fire resistance of steel structures that require fire protection treatment to achieve a rating of R15. According to SHNK 2.01.02-04 "Fire Safety of Buildings and Structures", roof structures in buildings classified as fire resistance level II must undergo fire protection treatment if the intrinsic fire resistance rating of each individual roof element is below R8. The intrinsic fire resistance limit
