Prestank, Structa’s flagship pressed-steel sectional tank, is hot-dip galvanised for corrosion control in accordance with SANS 121 (ISO 1461) galvanizing standards. The robust tank offers extended maintenance-free life when water with aggressively corrosive properties needs to be stored. It meets all properties for mining-specific water storage tanks.
There has been an increased need for water storage solutions for mining projects in remote areas in Africa in the past two years. Naturally, the preference is for water storage tanks that are robust enough for extreme environments.
Pressed-steel sectional storage tanks
Thanks to innovations in engineering, there are numerous liquid storage tanks on the market for mining houses to explore for their respective projects. One of the storage tank types that have proved their worth—and continue to do so—in tough conditions are pressed-steel sectional tanks, earning trust across industries.
Structa Technology’s Prestanks
Pressed-steel sectional storage tanks are a niche area where Structa Technology has excelled, emerging as one of the most highly regarded providers. Based in Gauteng Province, South Africa, steel tank manufacturer Structa Technology, a member of the Structa Group, provides robust temporary or permanent water storage installations for mining projects. The company is renowned for the fabrication of the premier Prestank. For over 40 years, consistently, the Prestank brand has been widely esteemed for being a hygienically safe, cost-effective, and reliable water-storage solution.
Meticulous engineering
Meticulous engineering has made Structa Technology’s high-quality Prestank suitable for rugged demands in the mining sector. It is fabricated in accordance with SANS guidelines and meets South Africa’s hot-dipped galvanising requirements.
Typically, all Structa’s pressed-steel sectional tanks are hot-dip galvanised for corrosion control in accordance with SANS 121 (or ISO 1461) galvanizing standards. Uniquely, the thickness of the hot-dip galvanising coat on the Prestank is applied within a range of 80 to 100 µm. This is more than five times what is regarded as the standard thickness of zinc on pregalvanized corrugated steel cylindrical tanks. This treatment ensures an extended maintenance-free life when water with aggressively corrosive properties needs to be stored.
Why the Prestank sectional tank design
A mining company can rest assured of the following main benefits by choosing Prestank:
- It features a variety of construction elements and an infinite range of sizes and configurations to meet clients’ specifications. These include walkway options and staircases, as well as roof options.
- The profile panel sections provide excellent strength properties and are structurally sound for storing water. Our Prestank range adheres to the following design codes: SANS 10160 for structural loading and SANS 10162 for structural steel design of tank stands. Tanks mounted on steel towers above ground level have an aesthetically pleasing
- Another significant advantage of the sectional tank design is that it facilitates easier handling and transportation over long distances to remote areas, regardless of the final dimensions of the assembled unit.
- On-site assembly is quickly achieved without the need for sophisticated tooling methods.
- Minimum maintenance is required as the galvanised steel panels resist weathering from the elements while maintaining the integrity of the water they hold and protecting them from most forms of contamination.
- Access to the water tank can be restricted using a lockable, ventilated access cover, providing safety and peace of mind for clients.
