different types galvanized plate 14 gauge galvanized steel sheet

The quality requirements of fine grade galvanized sheet include specification
size, surface, galvanized amount, chemical composition, plate shape, machine
function and packaging.

1. packing

It is divided into two kinds: galvanized sheet cut into fixed length and
galvanized sheet packing with coil. General iron sheet packaging, lined with
moisture-proof paper, outside with iron waist tie, tie firmly, to prevent the
internal galvanized sheet friction.

2. Specification and size

The product dimensions (such as the following and) are listed in the galvanized
sheet to promote the scale thickness, length and width and allowable faults. In
addition, the width and length of the board, the width of the volume can also
be determined by user request.

3. surface

General situation: Because of the difference in the treatment method of
galvanized plate in the plating process, the general situation is also
different, such as ordinary zinc flowers, fine zinc flowers, flat zinc flowers,
zinc flowers and phosphating disposal situation. Galvanized sheet and
galvanized coil cut to a fixed length shall not have defects affecting the use,
but the coil is allowed to have welding parts and other less deformed parts.

4. Galvanizing amount

Galvanizing measure value: Measuring galvanizing measure is a widely adopted
method to determine the thickness of zinc layer in galvanized sheet. There are
two kinds of galvanized quantity the same on both sides (equal thickness
galvanized) and zinc quantity on both sides (difference galvanized). Galvanized
units are g/m2.

5. Machine function

(1) Tensile test: Generally speaking, as long as the layout, tensile and deep
tensile galvanized sheet with tensile function requirements.

(2) Bending experiment: it is an important item to weigh the process function
of thin plate. But the world to all kinds of galvanized sheet requirements are
not the same. Generally, after the galvanized sheet is bent 180o, the outer
coating shall not have the zinc layer to leave, and the substrate shall not
have cracking and fracture.

6. Chemical composition

The requirements for the chemical composition of galvanized substrate vary from
country to country. If Japan has such a requirement, the United States does
not. Generally do not do product inspection.

7. Plate shape

There are two goals to weigh plate shape black and white, namely flatness and
sickle bend. The flatness of the plate and the maximum allowable value of the
sickle bend scale must be defined.

Minimum Order: 1 tons
