SR-TANK is an advanced STS water tank that completely removes weld deterioration corrosion with Bolting Type
PRESSED STAINLESS STEEL SECTIONAL WATER TANK
SR-TANK is produced by utilizing STS 444 materials which is most outstanding materials from stainless sorts in domestic side, and when its each panel is assembled, the way to assemble without welding could avoid becoming rusted on water tank. When it comes to damage destroying panels due to accumulated weight when putting water into tanks and draining water, STS 444(Duplex) is much superior than STS 303 for prevention. And inner parts of water tank comes to be rusted and be dirty and then finally durability of water tank is diminished with welded stainless (STS 304), on the other hand, SR-TANK chooses only bolt assembly rather than welding, this can be finest STS water tank which is competely far away from welding assembly.
Material
New type of stainless steel with outstanding corrosion resistance
New STS400 steel material containing molybdenum (Mo)
Shows powerful corrosion resistance with less generation of rust due to chlorine gas
Technique
Bolt assembly, panel joint technique
Completely eliminates the issue of rust generation thanks to a non-welding bolt assembly technique
Structure
System that emphasizes external reinforcement
Minimized internal horizontal reinforcing materials by employing the external frame reinforcement method
1-3mh: 100% external reinforcement type (no internal reinforcing materials)
Greater than 3.5mh: Internal and external mixed reinforcement type (no reinforcing materials on the upper section)
Increased sanitation and convenience in cleaning
