Our Flat Sheet Galvanized Bolted Steel Water Tanks use precision-cut hot-dip galvanized steel panels that bolt together on-site. The modular design allows tanks to be transported to any location — remote farms, mines, or urban sites — and assembled with minimal equipment.

With capacities ranging from 20,000 L to 5,000,000 L, these tanks serve farmers, municipalities, mining operations, government projects, and industrial facilities across South Africa and neighbouring countries.

Corrugated Steel
Galvanized Tanks

Corrugated galvanized steel tanks offer exceptional strength-to-weight performance. The corrugated profile provides structural rigidity without heavy gauge steel, making them cost-effective for farms, rural communities, and residential properties across South Africa.

Available from 5,000 L to 500,000 L, these tanks are ideal where flat-sheet bolted systems would be oversized. Rapid assembly and lower transport costs make them the preferred choice for agricultural and rural applications.
