Galvanizing service

Besides being the primary ingredient in galvanizing, Zinc is essential to life. In fact all organisms maintain the generally constant level of 20mg of zinc per kg. To achieve this for example, phytoplankton in the deep ocean must concentrate zinc obtained from seawater more than one million times.










No wonder then that zinc, through the galvanizing process, has become man’s most effective, readily available partner in the drive to preserve the life of the steel, which itself is such an important part of our world.













The galvanizing process is more than 250 years old. It is not generally known exactly when the South African galvanizing industry was first established, but the process is has been a mainstay of American industry since the 1890’s.















Items to be galvanised are first cleaned in heated washing dips to remove dirt, oil, soluble markings, surface rust and mill scale. After the pre-galvanizing process, the steel is then dipped into molten zinc heated to 435 to 455 degrees Celsius.












It is then inspected for coating thickness and surface condition. Once it has been returned to our factory, we file down rough edges as needed in preparation for possible painting and installation.s and deliveries from our premises.
