Galvanized Color Coated Steel Coil for Construction
Color Coated Gi Sheet Product Description
Prepainted galvanized corrugated sheet is also called profiled board. It us- es colored coated steel plate, galvanized plate and other metal plates to roll and cold bend into various wave pro- filed boards. It is suitable for roof, wall and internal and external wall decoration of industrial and civil buildings, warehouses, special buildings and long-span steel struct- ure houses. It has the characteristics of light weight, high strength, rich color, convenient and fast construction, ea- rthquake resistance, fire prevention, rain proof, long ser- vice life, maintenance free and so on.
Color Coated Gi Sheet Product Parameter
PPGI is pre-painted galvanised steel, also known as pre-coated
steel, coil coated steel, color coated steel etc., typically with a
hot dip zinc coated steel substrate. The term is an extension of GI which is a traditional abbreviation
for Galvanized steel. Today the term GI typically refers to essentially pure zinc
(>99%) continuously hot dip coated steel, as opposed to batch
dip processes. PPGI refers to factory pre-painted zinc coated steel, where the
steel is painted before forming, as opposed to post painting which
occurs after forming. The hot dip metallic coating process is also used to manufacture
steel sheet and coil with coatings of aluminium, or alloy coatings
of zinc/aluminium, zinc/iron and zinc/aluminium/magnesium which may
also be factory pre-painted. While GI may sometimes be used as a collective term for various hot
dip metallic coated steels, it more precisely refers only to zinc
coated steel. Similarly, PPGI may sometimes be used as a general term for a range
of metallic coated steels that have been pre-painted, but more
often refers more precisely to pre-painted zinc coated steel. Zinc coated steel substrate for PPGI is typically produced on a
continuous galvanizing line (CGL). The CGL may include a painting section after the hot dip
galvanising section, or more commonly the metallic coated substrate
in coil form is processed on a separate continuous paint line
(CPL). Metallic coated steel is cleaned, pre-treated, applied with various
layers of organic coatings which can be paints, vinyl dispersions,
or laminates. The continuous process used to apply these coatings is often
referred to as Coil Coating. The steel thus produced in this process is a prepainted,
prefinished and ready for further processing into finished products
or components. to use material. The coil coating process may be used for other substrates such as
aluminium, or aluminium, stainless steel or alloy coated steel
other than “pure” zinc coated steel. However, only “pure” zinc coated steel is typically referred to as
PPGI. For example, PPGL may be used for pre-painted 55%Al/Zn alloy-coated
steel (pre-painted GALVALUME steel).
