WHAT IS ZINCAL?
The mild steel substrate is continuously hot dipped in a formulation of Aluminium (55%),
Zinc (43.5%) and Silicon (1.5%). The combination of Aluminium and Zinc increases the
sacrificial properties therefore extending the service life span of a steel roof by up to
4 times that of galvanised steel. The Aluminium components of the coating provide a
tough physical barrier between the extreme atmospheric conditions and the inner core
of steel. The Zinc in the coating protects the steel where exposed.
