The presssed steel tanks can be elevated on structural steel towers. Strictly designed based on national structural design code, based on different region's climate with good wind resistance, earthquake resistance,weather resistance, etc. The panels are bolted together and are brased from the inside. All pressed steel panels are hot dipped galvanised – hence corrosion resistant, making this product particularly durable and suitable for storage of potable water.
