🔍 What Is a PE Water Tank?
A PE (Polyethylene) water tank is a lightweight, non-corrosive, and hygienic tank made from plastic that is safe for drinking water storage. PE tanks do not rust, and their UV-stabilized exterior makes them highly resistant to Malaysia’s weather. One-piece rotational molding ensures a strong structure that won’t crack or leak easily.
PE tanks like the Kossan N400RA are popular for domestic use, commercial storage, farming, and construction sites because of their reliability and low maintenance needs.
