Every Aquasteel tank is matched to the coating specification, structural load and risk profile of the project. We don't supply catalogue tanks — we engineer water storage infrastructure.
Compare the Range
A quick comparison across coating, application and ideal use. The correct choice depends on water source, volume, chemistry and risk tolerance.

The Range in Detail
South Africa's sectional bolted FBE steel water tank, engineered for permanent corrosion control in aggressive pH 2–11 environments. The specified choice for municipal bulk water storage, mining process water, high-chlorine conditions and fire protection. When failure costs millions, Rhino Tank™ is specified.
Engineered corrugated ZINCALUME® grain silos for maize, wheat, soya, sorghum and sunflower — sized in tons (~135 t to ~2,800 t), with aeration and auger discharge.
Bridges performance and budget. High-grade PosMac® (Zn-Al-Mg) flat-panel steel with optional PVC AquaGuard liner for potable and non-potable use — ideal for commercial developments, schools, hospitals, agriculture and backup storage. Best cost per kL, maintained structural integrity.
Engineered residential water storage built from Chromadek steel for durability and aesthetic integration — for rainwater harvesting, estate backup systems, off-grid living and drought resilience. Reliable engineered storage, correctly sized and installed.
