Fire protection through hot-dip galvanizing is simplified
Approval in individual cases will not apply in the future
Hot-dip galvanizing improves the fire resistance of steel structures, as hot-dip galvanized steels are characterized by lower emissivity. Emissivity is a measure of how strongly a material exchanges thermal radiation with its surroundings. Especially in the initial phase of a fire, reduced emissivity values lead to significantly delayed heating of the steel components and can make a significant contribution to achieving the required fire resistance of R30, especially in the case of components with sufficient solidity. Construction projects that have already been completed show the diverse range of uses for fire protection through hot-dip galvanizing in steel construction. Hall buildings, residential and commercial buildings, individual supports, pergola constructions or buildings such as rooftop areas or industrial extensions are just a few examples. If you want to use hot-dip galvanizing for fire protection, you have to provide mathematical proof by means of a hot calculation. For this purpose, the Hot-Dip Galvanizing Institute offers a free dimensioning tool. In addition, software manufacturers such as mb AEC Software and Dlubal Software have design programs for fire protection through hot-dip galvanizing in their portfolios.
