The stainless steel plate water tank adopts to the import food level SS304,SS316 stainless steel plate, blocking-up the sunlight irradiation thoroughly, does not multiply the algae, at any time maintains the water quality is clean.It can eradicate the second pollution completely. The stainless steel plate has light weight and high strength. The yield strength of stainless steel is equivalent to 1.5 times that of carbon steel and 6 times that of GRP. Compared with the SMC water tank, the stainless steel water tank has the better high temperature resistant performance. So it can apply to the request of fire and building standard act completely. Stainless steel water tank adopts to the all welding assembly. Compared with the traditional water tank which connection by bolt, it get rid of the sealing strip and bolt to make the water tank more strength and never leakage.
