Galvanized wire is made of high quality low-carbon steel wire rod processing,
which is made of high quality low-carbon steel. After drawing molding, pickling
rust, high temperature annealing, hot dip galvanized and cooling process. That
is hot dip galvanized wire.
Good coating surface galvanized wire products, and have continuous smooth
usability, installation combined with plating is not sagging, dripping or
leaving the presence of slag plated surface should be seamless plated, exposed
iron and other defects. Note (allow defects): Leakage plating area of 0.5 mm
diameter or less spots; regardless of the size of plating, plated drain area
0.5-1 mm in diameter spots within each square centimeter of more than 3:00, and
plated the total number of spots member does not exceed 10 points; in the
non-coupling or connection angle at a height of not more than 1.5 mm of sag or
drop to stay slag; plating with hanging and operating tool in contact wounds,
but not exposed iron. Good galvanized wire, plating thickness of 3-4 mm, zinc
coating weight should be less than 460 g / m, that is, the average zinc coating
thickness not less than 65 microns; when the plating thickness greater than 4
mm, zinc coating weight should not be less than 610 g / m, that is, the average
zinc coating thickness of not less than 86 microns; standard galvanized wire
coating must be uniform, with zinc coating substantially uniform etching copper
sulfate solution tests do not reveal the five iron. Standard galvanized wire
coating adhesion requirements, zinc plating layer and base metals should be
combined with a solid enough adhesive strength, the hammer test does not fall
off, not projections.
I hope that the news is useful for you. Welcome to change your info with me
about galvanized iron wire or galvanized steel wire.
