Galvanized Steel Coil Coating Thickness
Shandisa hukama hunotevera kufungidzira ukobvu hwekuputira kubva pahuremu hwekuputira [misa]:
1.00 oz / ft2 coating uremu = 1.68 mils coating ukobvu,
7.14 g/m2 kupeta huremu = 1.00 µm ukobvu hwekufukidzira.
Shandisa hukama hunotevera kushandura huremu hwekuputira kuita huremu hwekuputira:
