Galvanized steel wire testing and laboratory quality inspection report
What are the inspection items for galvanized steel wire? How to process the testing report? How long is the testing cycle? How long is the validity period of the report? What projects are being tested? We only do real testing.
Testing items:
Zinc coating test, dimensions, mechanical properties, torsion test, repeated bending, weight of zinc layer per unit area, adhesion of zinc layer, uniformity of zinc layer, straightness performance, surface quality, isothermal relaxation test, zinc layer copper sulfate, zinc layer quality, partial parameters, mesh strength, zinc layer quality, zinc layer content, mesh size and wire diameter, copper sulfate test
