High zinc layer no fancy galvanized sheet Galvanized coil 275g zinc layer

Generally speaking, only structural, tensile and deep drawing galvanized sheet
have tensile performance requirements. The structural galvanized sheet requires
yield point, tensile strength and elongation. Only elongation is required for
stretching. Test method: The same as the general test method of thin steel
plate, bending test: bending test is the main project to measure the process
performance of sheet metal, but the national standards for all kinds of
galvanized sheet requirements are not consistent, except structural grade, the
rest are not required to bend and tensile test. In Japan, bending tests are
required except for structural grade, architectural corrugated plate and
general corrugated plate. Requirements: The general requirements of galvanized
sheet bending 180, the outer surface shall not be separated from the zinc
layer, the plate base shall not have cracking and fracture.

Galvanized sheet is a steel plate coated with zinc. Is to prevent corrosion on
the surface of the steel plate to prolong its service life, coated with a layer
of metal zinc on the surface of the steel plate, is a kind of economic and
effective rust prevention method, the zinc coated steel plate is called
galvanized plate, galvanized coil plate and divided into no zinc flowers, small
zinc flowers and zinc flowers.

Zinc flower diameter 1~2mm zinc flower called small zinc flower. When the hot
galvanized sheet comes out from the zinc pot, to the zinc layer without
solidification spray or zinc powder, a water drop, a zinc powder particles will
form a crystallization center, so that the unit area of zinc flowers increased
and became smaller, so the galvanized surface will form with the naked eye can
distinguish small zinc flowers, traditionally the product produced by this
process is called small zinc flowers. Because this process often causes uneven
zinc flowers, uneven surface color, and high production cost, so this process
is not used much.

Large zinc flowers are not allowed to enter the finishing process. Small zinc
flower or no zinc flower products through the finishing process, known as
finishing zinc flower. This plate through the light of the galvanized sheet
polishing machine, the galvanized sheet surface of the zinc flower flat is
mainly used for color coated coil plate.
