Engineered for Africa · Since 1992
Aquasteel manufactures engineered FBE, sectional, corrugated and Zincalume steel water tanks and grain silos — specified for five applications: municipal, mining & industrial, fire protection, agriculture & grain, and commercial & residential backup.
We don't compete on price. We compete on engineering, coating specification and risk control — and the tank pays for itself, typically in 2–6 years.

Frequently Asked Questions
A bolted steel water tank coated with thermoset epoxy powder cured at high temperature to provide corrosion resistance compliant with AWWA D103.
Fusion Bonded Epoxy provides enhanced corrosion resistance in aggressive water conditions compared to traditional galvanised coatings.
Fusion Bonded Epoxy bolted steel tanks are typically specified for mining due to chemical resistance and structural durability.
Usually yes. Counting avoided cost — rainwater replacing bought water, downtime prevented, tanker deliveries eliminated and cheaper tanks no longer replaced — payback of 2–6 years against a 30+ year design life is common. Run your own numbers in the ROI calculator, or read what a steel tank really costs.
Yes. Aquasteel manufactures and delivers engineered steel water tanks nationwide and across selected African regions; installation is handled by our approved local partners.
The best steel water tank for South African conditions is one engineered for high UV exposure, variable water chemistry, wind load and remote installation — not simply the cheapest option. Aquasteel's Rhino Tank™ with Fusion Bonded Epoxy (FBE) coating is specified for aggressive environments where galvanised or plastic tanks fail prematurely. For agricultural and commercial applications, the Dura Tank™ offers engineered storage scaled to your volume and budget.
Trusted Across Sectors
"We have procured and installed various tanks from 36m³ to 1268m³ all over South Africa and abroad. Aquasteel has delivered good quality tanks and good service over the years. Hydrotek would have no reason not to recommend Aquasteel's products for all your water storage needs."
"We have purchased Aquasteel tanks in Zimbabwe for the last 6 years — from the 30,000L Express Smart Tank up to the 1,500,000L Smart Tank Extreme. Great value for money, easy to construct, and very impressive structures. Most of our customers buy Aquasteel just from seeing other installed tanks."
"You installed a 280,000L ST154 tank as part of a water recycling plant upgrade, now in full operation. On behalf of Namib Poultry, thank you for the quality, value-for-money products, professional advice and problem-free installation."
