Boasting anti-corrosive and anti-aging capabilities, the products can withstand all types of adverse weather conditions. Inherently endowed by fiberglass itself, these products exhibit exceptional resistance to high and low temperatures (operable within a range of -50~160℃), superior chemical inertness (resistant to acids, alkalis, salts, organic solvents, and other corrosive substances), as well as remarkable dimensional stability—characterized by an extremely low coefficient of thermal expansion, which is 12×10⁻⁶/℃.

The SMC composite water meter boxes are anti-corrosion resistance, coloration.
