Behavior of bent steel during hot-dip galvanizing
Bending metal - it is nothing like its cold treatment. It is necessary to weigh the pros and cons and be sure to consult with a specialist before the procedure of this kind of galvanizing. As practice shows, to obtain the desired result without breaking the structure and deformation, it is necessary to make the greatest bending radius. If the radius is small, you need to heat the product as much as possible in order to reduce the voltage.
Galvanized steel is subject to a strong temperature drop, which results in such consequences as cracks and other defects on parts with a large number of cold treatment. To avoid unnecessary stress, which occurs, including, and in the outer radius of bending, be sure to expose the metal structure to heat treatment at t = 593°C for an hour.
