Water Tanks: What is The Best Metal Material to Build One?

08 November 2022

Tanks are specialised storage containers used for both industrial and domestic applications. Water, oil, hazardous waste, chemicals, and other materials that must be kept at a facility or house for an extended period can all be kept in tanks. In reality, though, several tanks have various functions. The materials utilised during manufacture determine the function it serves. This blog will discuss the best material commonly used to build water tanks.

Aluminium

Aluminium is a light, silvery-white metal. It is bendable and soft. Numerous items, such as cans, foil, culinary utensils, window frames, beer kegs, and aeroplane components, are made of aluminium. It is naturally resistant to corrosion, although aluminium is potentially challenging to handle since it needs unique welding procedures. It is abrasive to tooling, or more precisely, the layer of aluminium oxide that forms on top of it is abrasive. It is costlier than steel. Aluminium isn’t as resilient or powerful.

Stainless steel

A variety of corrosion-resistant alloy steels containing at least 10.5% chromium are collectively referred to as stainless steel. The corrosion resistance is very good in all stainless steel. The naturally occurring film of chromium-rich oxide that forms on the steel’s surface gives it this resistance to attack. The most popular material for water truck tank construction nowadays is stainless steel since it is more ecologically friendly, naturally strong, durable, and corrosion-resistant. It also offers the greatest, most practical, long-term solution to handle the harsh Australian environment.

Galvanised Steel

Regular steel sheets are coated in zinc and then rolled into galvanised steel to prevent corrosion. Galvanizing was developed to aid in rust and corrosion control. Because “normal” steel is made of iron, which rusts when exposed to moisture of any kind, including rain, condensation, sea air, and even high humidity, this distinction is crucial. The steel will be destroyed by rust until it flakes and falls apart. Whereas previously, this was the most cost-effective way, galvanised steel is now notorious for negatively influencing the environment.

Plastic

The most affordable and popular type of tank is plastic. The raw material utilised to make these tanks, polyethylene, is a solidified rubber that strikes the perfect balance between being too brittle and pliable. Depending on the manufacturer, it can be acquired quickly and affordably. Plastic tanks are made following tank design codes to withstand impact from mechanical stress and solid objects, should that be the case. However, given the nature of the material, such resistance has a limit; even when the wall thickness is designed following design codes, a heavy enough impact would still damage the tank wall. Plastic tanks, however, hold up well enough to last a proper lifetime.

Which Material is Best for Water Tanks?

Although there are many choices, plastic is the ideal material for water tanks. These tanks are made of polyethylene, which makes them non-corrosive and long-lasting. The best thing is that these tanks don’t rust or corrode, unlike metal and concrete. These tanks are also incredibly portable and lightweight. These tanks can be installed or relocated without the use of heavy machinery. Most poly tanks are manufactured as a single piece without seams or joints. So, the tank’s joints are all made without sealants. Its most interesting feature is the ability to be recycled after a poly tank has reached the end of its useful life.
