1.Production process
It is produced on the base plate of prime aluzinc coated steel
coils through surface pretreatment (degreasing and chemical
treatment) and then being coated with one or several layers of
liquid coating material by roller coating before being baked out
and cooled down. Such coated steel sheet in coils is called as
color coated steel coils because the coating can be with different
colors, and it’s also called as pre-painted steel coils overseas
because coating is finished before contour machining.
2.Features of PPGI.
(1)Beautiful architectural images
Membrane structural architecture is the most representative and
promising architectural form in the 21st century. It breaks through the linear architectural from, brings
people a brand new feeling with beautiful curved surfaces and
perfect combinations of simplicity and lucidness, rigidness and
flexibility ,power and aesthetics ,and suppliers
architects with larger space for imagination and creation.
(2)Favorable self-cleaning performance
The surface of such membrane material has a protective coating with
a favorable thermo-insulating property, by which, 70% of the solar
heat can be reflected away. Based on a favorable self-cleaning
performance, 70% of the brightness can be still reserved after 10
years’ direct sunshine.
(3)Flame resistance and shock resistance
The membrane material used by a membrane structural architecture
has great flame retardance and high temperature resistance, and
thus it can satisfy the requirement for fire prevention. it also
has a favorable shock resistance because of low deadweight and its
flexible structure with large deformability.
(4)Short construction period
Cutting, piecing together, steel structure and steel ropes are all
finished and prepared in the factory, and it only requires
assembling on site, therefore the construction is simple and
convenient, and the construction cycle is shorter than that for a
traditional architecture.
