I know what you are hesitating about, so I will do my best to give you enough purchase protection!
How to test the adhesion of zinc layer?Through hammer test (ASTM A123) or copper sulfate immersion (5 times without iron exposure)
Do you provide third-party quality inspection report (such as SGS)?MTC (material report) + zinc coating thickness test report for each batch can be provided
Inner wall treatmentsandblasting/pickling
End protectionplastic cover/anti-rust paint (to prevent transportation bumps)
Special certificationdrinking water pipes require NSF/ACS certification (such as ASTM A106 galvanized pipes cannot be directly used for drinking water)
Is the weld subjected to non-destructive testing?Provide eddy current flaw detection (ET) or ultrasonic flaw detection (UT) report (in accordance with EN 10246)
How to ensure the uniformity of zinc layer?Adopt centrifugal zinc-spinning process and implement ASTM A123 three-point test method for zinc layer thickness
Zinc contentComply with EU RoHS (lead and cadmium content
Can it meet special needs?Can be shipped with ASTM standard number + manufacturer logo, etc.
Galvanized layer lifeProvide salt spray test report (such as 480 hours white rust does not exceed 5%)
Customized serviceCan do flaring/grooving/thread processing (processing fee is calculated separately)
