Aluzinc Round Steel water Tanks

Aluzinc round steel tanks are made with a mixture of Iron, silicon and Aluminium frames with an inner liner of PVC or TPU depending on stored liquid or usage of the industrial tank. The height of the Aluzinc Reservoir allows for more liquid volume per square meter on the ground in comparison to stand alone bladder, corrugated or pressed steel tanks.

Exceptional Quality

The design is in accordance to a recognized code of practice, this enables FTS to design various custom water tanks for numerous projects according to specific design codes and standards.

The Aluzinc Steel round water Tank is designed to stand up to aggressive wind loads in specific regions where hurricanes, high winds and thunderstorms occurs regularly. The tank shell can be adapted to any bespoke needs, we can adapt the wall sheet thickness, roof sheeting and truss design for a more durable structure when nature comes thundering down.

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

A lightweight Aluzinc roof designed to withstand wind speeds of up to 100km an hour can cover tanks. Roofs are fitted with a hatch, internal and external ladder for easy access inside the tank. Tank can also be sealed with felt seal to avoid insects, 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. Ringbeam design is dependent on the tank size and location.

Multiple Applications

The Aluzinc water tank is suitable for a wide range of applications. In the agricultural sector they are ideal for irrigation, stock and poultry use. Additionally, they are widely used in the Industrial and Mining sector, for rural and domestic water storage, grain storage, waste water treatment plants, township development and for storing potable water in security estates. Furthermore, they can be used for certain chemical storage applications depending on the liner type and the chemical being stored. What’s more, their exceptional fireproofing qualities make Aluzinc or zincalume tank ideal for firewater storage tanks
