PDS panel tank
Seo Heung Industry Co., Ltd has manufactured and developed a tank for drinking water and installed STS WATER TANK, PDF TANK, SMC TANK and etc. from the beginning, and has supplied a water tank in eco-friendly and sanitary material in order to consistently keep clean drinking water for about 20 years, and through the efforts of our research team, much cleaner and stronger PDS drinking water tank has been spread. What is PDS Panel?
"PDS" Panel is the steel plate to be compressed and molded by the material of Low Density PolyEthyelene sheet and hot dip galvanized steel and then pressed. This PANEL is assembled and used for the purpose of the water tank.

Characteristic OF PDS panel tank
As LDPE is a material that is harmless to human body, the drinking water is stored in a sanitary manner, and unlike GRP(smc) tank, the bottom panel of "PDS-PANEL" is assembled in a "FLAT" state to enable debris and sludge easy to move when a water tank is cleaned, and its features and benefits are that"DRAIN PANEL" is equipped to be completely drained.

The side panel uses the bracket to unite 4 pieces and it is the way of making the long bolts stick out from the inside to the outside to secure the nuts from the outside.
Internal bracket is made of the STS304 material to increase the strength of steel under the water pressure.

All internal supports should be reinforced with the angle of the STS304 material and the angle should be coated to prevent rust, and the area where the angles of the internal support are crossed should be secured with the STS bolts.

The installation of a partition (2.3.4) is also available so that the water can be used differently depending on the application. Also, put a 25t urethane board on the outside to prevent condensation and freezing and finish the exterior on it with 0.4mm color steel plate.

After using PDS PANEL tank, you can disassemble, clean and move it to the other place and reuse it. PDS is only a water tank with a large capacity in the world which can be assembled without electrical welding by metallic materials, and we are trying to continue the evolution of a water tank and will increase a self-esteem as a global company for a water tank.

PDS PANEL tanks can be used in different areas for many purposes.
