3. Versatility Modern downspout machines can handle various materials and profiles, accommodating the unique needs of different projects. Whether it’s a residential building or a commercial complex, these machines can be adjusted to meet specific design requirements, including custom colors and coatings.
4. Annealing Following the cold rolling process, the steel strips may require annealing. This heat treatment process relieves internal stresses that develop during cold rolling, restoring ductility and reducing hardness. The annealing process can be performed in a continuous furnace where the steel strip is heated and then gradually cooled.
