What is Stainless Steel Water Tank

Stainless steel grades,such as the 316 or 304 types which are generally suitable for storing both cold and heat drinking waters.There are two connection ways including bolt-connection and welding connection.For welding one,it is connected through argon welding way and it is more fast to installation completion.Both two types stainless steel water tank could meet the high precise science and technology water storing or somewhere with strict water quality demands.In addition,stainless steel welding water tank is afraid of high chloride concentration water.Welding point will reduce the nickle content and lose the ability to prevent corrosion from high chloride water.

1.The size of stainless steel panels are produced by standard with 1*1 m, 1*0.5 m and 0.5*0.5 m.

2. The panel thickness is depends on tank height.

3.The maximum height available is 6.5 meters (Need add C-channel external reinforcement if over 5.5 m height).

1. Stainless steel water tank usually in short of SS or SUS water tank which consists of three types of panels which is customizable from 0.125 m3-5000 m3.

2. The water tank is usually set within 4 meters high,we have set the water tank height up to 6 meters already with high technology.

3. Stainless steel water tank is easily loaded for light weight and usually packed in plywood case and  loading most compare with other types of tanks.

4. Stainless steel water tank warranty time is 18 months since shipped out factory or 12 months since installation,based on closed one.

5. Stainless steel water tank can store many kinds of water,specially for high quality water,but always compromised to sea water or water with rich chloride.


1. All panels and accessories are both stainless steel materials,comply with national standard.

2. Panels consist of 1000 x 1000 mm,1000 x 500 mm,500 x 500 mm three types.

3. Water tank could be assembled either welding connection or bolt connection.

4. U-steel is optional between hot dip galvanized and painting.

5. It can be used overhead water tank and insulated water tank.

Stainless steel welding connection water tank installation video




The raw material adopt pure stainless steel 304 or 316; it has excellent corrosion resistance.


The stainless steel material can be implanted into the human body, it is very best healthy material for us.


Our raw material are all international famous brand. Tank life-span can be over 1/4 century.


Factory precast panel is easy to assemble and disassemble, the construction drawing, installation video, and a series of complete installation plan will be provided.


For argon arc welding type, all the welding process are handle from inside the tank, so there’s no need left space around of tank.



As over 20 years of water tank manufacturer,we have established 4 production lines separately for GRP modular water tank,HDG water tank,Stainless steel water tank,GSC underground water tank,which include 58 skilled engineers, 8 sets of molding pressure machines.

Except above water tank series,we could process and customize other SMC products such as electric pole protection cases,farm planting SMC series.
