The steel panels of the tank are coated with a zinc layer on both sides. The corrugated steel sheet is continuously hot dipped in a formulation of Aluminum (55%), Zinc (43.5%) and Silicon (1.5%). The aluminum components of the coating provide a tough physical barrier between the extreme atmospheric conditions and the inner core steel. Zinc has inherent sacrificial properties and corrodes first before the mild steel corrodes. 

 A lightweight zincalume roof designed to withstand wind speeds of up to 55m/second can cover tanks. Roofs are fitted with a hatch, internal and external ladder for easy access inside the tank. Tanks can also be sealed with felt to avoid insect and dust contamination. All commercial and industrial water storage tanks require the construction of a concrete ring beam footing. It is imperative for the client to ensure that the foundation and civil works for the site are adequate. Ring beam design is dependant on the tank size and location. 

This high quality panel-type reservoir is a modular steel tank storage solution that bolts together for easy installation. A certified potable liner with woven base fabric polyester yearn ensures safe water storage for drinking. With capacities ranging from 16m3 to 3 100m3, these steel coated panel tanks are available in a multitude of design specifications depending on the client’s requirements, ranging from 3,0m x 2,34m high to 22,28m x 8,18m high. 

 Our Zincalume coated tanks are very competitively priced and due to the modular nature can be installed extremely quickly by a certified installer, even in difficult or remote sites anywhere around the world.
