Lokacin ƙayyade ko siye HDPE Geomemlane, you will encounter two units of measurement for thickness: millimeters (mm) and mils. One mil is equal to one-thousandth of an inch (0.001"). Since we work with clients globally, being comfortable with both is essential.
Anan ga ginshiƙi mai saurin canzawa don mafi yawan kauri na geomembrane HDPE:
- 0.5 mm = 20 mil

- 2.0 mm = 80 mil
- 2.5 mm = 100 mil
