When it comes to large-scale liquid containment, pressed steel tanks are the industry standard for durability and modular efficiency. Rainbow Reservoirs specializes in premium sectional tanks constructed from hydraulically pressed steel panels, designed to provide high-volume water security for industrial, municipal, and agricultural applications across Africa.
Our pressed steel sectional tanks offer a "Lego-like" assembly that redefines bulk storage. By utilizing high-strength Aluzinc® or galvanized steel panels, we deliver a reservoir system that combines the structural integrity of traditional engineering with the rapid deployment required in today’s fast-paced infrastructure environment.
Traditional one-piece tanks often struggle with transport and capacity limits. Our pressed steel tanks solve these challenges through a modular, bolted design that offers several strategic advantages:
• Superior Corrosion Protection: We utilize advanced Aluzinc® coatings—an alloy of Aluminum, Zinc, and Silicon—which provides up to four times the lifespan of standard galvanized steel without the need for additional maintenance.
• Massive Capacity Range: Our hydraulic pressing technology allows for the construction of modular tanks ranging from 5,000 litres to over 5 million litres.
• Remote Location Accessibility: Because our pressed steel panels are delivered in a "flat-pack" format, they can be easily transported to restricted-access urban sites or remote mining operations where traditional construction is impossible.
• Versatile Installation: Our tanks can be installed at ground level or elevated on structural steel towers (tank stands) to provide gravity-fed pressure for municipal or fire-fighting systems.
• Hygienic & Potable Safe: Equipped with heavy-duty, food-grade RPVC liners, our tanks ensure that stored water remains untainted, odorless, and safe for human consumption.
Rainbow Reservoirs delivers custom pressed steel tank solutions tailored to meet the highest safety and quality benchmarks:
• Fire Protection: Fully ASIB-approved pressed steel tanks designed for reliable water supply in commercial and industrial fire suppression systems.
• Mining & Industrial: Rugged, heavy-duty panel systems capable of storing process water, wastewater, or raw materials in the most extreme environments.
• Municipal & Communities: Rapidly deployable reservoirs for schools, hospitals, and rural communities to ensure consistent water access during droughts or infrastructure failures.
• Agriculture: High-capacity storage for large-scale irrigation and livestock watering, built to last 40+ years under the harsh African sun.

Q: What makes a "pressed" steel tank different?
A: The term refers to the manufacturing process where steel plates are hydraulically pressed to create flanges and structural profiles. This increases the strength-to-weight ratio, allowing the tank to hold massive volumes without warping.
Q: Can these tanks be elevated?
A: Yes. Our pressed steel sectional tanks are frequently installed on steel towers to provide the necessary head pressure for fire sprinklers or rural water distribution.
Q: Do I need a concrete base for all sizes?
A: No. Many of our standard range tanks under 350,000 litres can be safely installed on a well-compacted sand bed or ring-beam, saving you time and civil engineering costs.
Invest in a water storage solution that offers permanent reliability. Rainbow Reservoirs provides the expertise and engineering needed to secure your water future with premium pressed steel tanks.
