Galvanizes Sheets

This specification for hot-dip zinc-coated steel sheets in flat, corrugated sheets and coils is applied for testing the qualities of hot-dip zinc-coated steel sheets in flat, corrugated sheets and coils of Vnsteel Thang Long. This standard based on Japanese Industrial Standard JIS G3302, European Standard EN10142 and American ASTM A653/A653-08.

2. Product’s quality specifications

 2.1. Bend test

his test is to test the adhesion of zinc coating at 180⁰, there shall not be any flaking of the coating, cracking (visible to the naked eye) or fracture of the base metal on the outside of the bend portion. Standard for bending test is 0T-2T.

2.2. Tensile strength

 Remark: The standard applied for corrugated sheets. Other standards shall be agreed between the purchaser and manufacturer.

2.3. Coating mass
