G550 Galvalume Steel Coils And Sheets 55% Aluzinc Full Hard JIS GB
GL is more popular in recent years, especially popular in Philipine
due to the merits of PPGL, which suitable for the enviroment there
Firstly, the corrosive resistance of the hot-dip alu-zinc coated
steel sheet is twice to fifth times as mush as that of the hot-dip
zinc- coated base metal.
Secondly, it can satisfy the processing requirements of rolling,
coiling and others processes alike.
Thirdly, the color won't change while continuously or
intermittently working with an ambient temperature up to
316℃.Neither serious oxygenation nor oxide scale might appear while
continuously or intermittently working with an ambient temperature
up to 490℃.
Thirdly, the heat and the light reflected are respectively twice as
much as those of hot-dip zinc steel sheet, and its reflectivity is
more than 0.75, exceeding 0.65 (required by the EPA Energy Star
Standard), which is an ideal construction material of saving
2. Mechanical properties of hot dip Al-Zn base
Mechanical properties of steel sheet and steel strip should be in
conformity with the stipulations of following table.
Due to effects of aging, mechanical properties of the steel strip
shall deteriorate with storage time passing, E.g. yield strength
and tensile strength will rise, elongation after fracture
decreases, formability deteriorates etc. it is suggested to use the
material as soon as possible.
|Yield strength (Mpa)||Tensile strength (Mpa)||Elongation A80%|
For products with nominal thickness greater than 0.50mm, but less
than or equal to 0.70mm, the elongation after fracture is allowed
to decrease by 2 units. For products with nominal thickness not
greater than 0.50mm, the elongation after fracture is allowed to
decrease by 4 units.
3. Storage of products
Products should be stored in a dry and ventilated room, instead of
being stored in the open air or a place with moisture and a great
change of temperature.
The products should be stored in a clean and neat enviroment,
preventing from various corrosive substances.
The storage place should be smooth and level, have a good bearing
Horizontal steel coil should be placed on the brackets with rubber
cushions or wooden cushions and be locked with the lock catch on
the topside. It mustn't be placed on to the fround or vehicles
To avoid being pressed, the steel coil mustn't be stored in
stacking. When the steel sheets are stored in stacking, a limit to
every stack should be specified and the sheets with large weight
and size should be placed in the lower part of the stack.
The storage of the steel sheets and coils should be scientifically
arranged in advance, so as to avoid unnecessary shifting.
