Correctly measuring fire protection coatings
Steel beams and steel structures form the basic framework of many buildings. In the event of a fire, they can be exposed to extreme heat and quickly become unstable.
Therefore, many of these constructions are coated with intumescent materials that swell up when heated, forming a thick, foamy layer that insulates the underlying structure and increases its ability to withstand fire. Internationally, there are several different minimum requirements that apply to such fire protection coatings.
Usually, the layers are 6 – 7 mm in thickness, although they can even be as thick as 20 mm.
Because human health and safety depend on how reliably these protective coatings work, their quality must be controlled meticulously.
