Posted: June 23, 2017 |
It’s a good decision to get rain water collected for future use. For this, rain water tanks are available. There are various types of rain water tanks available. These are made from different materials such as Concrete Tanks, Bladder, Metal Tanks, Steel Tanks and Polyethylene Tanks. Here, in this blog; we will discuss the difference between Polyethylene tanks and Steel Tanks. So, let’s begin: How do Polyethylene and Steel Tanks vary from each other? Among various types of rain water tanks available; Polyethylene are highly in demand and another choice is Stainless steel slimline rain water tanks. We will here compare both of them but before that we must know that there are various grades of steel and these grades are often expressed by numbers. For instance, Kitchen sink is made from steel having grade 304. Steel has chromium as a base element that is used to avoid corrosion. To remove the corrosive effects of sea water, chemical molybdenum is also added. This is also used in surgical equipments and stainless steel implants. In Steel water tank, stainless steel of 304 grade is used. It is advisable to confirm with the supplier about the grade of stainless steel used before purchasing the steel tank. This will make it easy to compare the tanks quality wise, strength wise and also ease of installation. Points of difference between Polyethylene and Steel Rain Water Tanks: Installation: For both tanks firm foundation is a preferable however for plastic tanks , the base is of crusher dust while for steel tanks; the base must be compact and must have a solid foundation. Make sure that the foundation is protected from getting eroded. Steel tanks once installed may not be moved again unless otherwise needed. Moving again can affect its structure as well as chances of leaks increases. On the other hand, poly water tanks are lighter and easier to move. This means shifting it from one place to another doesn’t affect its structure. Duration: Poly tanks can last up to 20 years or more as this can bear the harsh sun rays as UV stabilizers added to it prevent the tank from becoming brittle and decomposing. Stainless steel tanks must be kept clean. Solvents like salty sea water and chlorine must be kept away as these might cause corrosion. Avoid burying them as this can result into leaking tank. According to reports, it is proved that these tanks usually start leaking after two years due to poor manufacturing process hence it is necessary to conduct complete survey and gather all details before installing them. Warranty: Warranties for both tanks are different. As per the steel quality, warranty varies in stainless steel. Usually, warranty for any steel tank is 30 years or more however the actual manufacturing is different.
Reports show that they last for 15 years or more but practically these usually start leaking within 2 years due to corrosion of screws that join the steel sheets together. In case of plastic tanks, they have warranty of 25 years maximum.
In terms of warranty, plastic tanks are more preferred than steel ones. Based on these differences, we can see both tanks have their own pros and cons. Some prefer to have slimline stainless steel tanks as they occupy very less space and are easy to fill. They are available in various fashionable colours and have two years warranty against rust and corrosion. So, if corrosion and rust is the reason you are avoiding to buy steel tanks then this is the perfect solution for you.
