Hot Dipped Galvanized/Galvanneal Steel Coils Zinc Coated 40-400g
Introduction of Hot Dipped Galvanized/Galvanneal Steel Coils
Galvanized steel coil, immersing the thin steel plate in the molten
zinc bath, and adhering a layer of zinc thin steel plate on the
surface. It is mainly produced by the continuous galvanizing
process, that is, the coiled steel plate is continuously immersed
in the zinc-melted plating tank to make galvanized steel plate;
alloyed galvanized steel plate. This kind of steel plate is also
made by the hot-dip method, but it is heated to about 500 °C
immediately after exiting the tank to form an alloy film of zinc
and iron. This galvanized steel coil has good paint adhesion and
weldability.
The Advantage of Hot Dipped Galvanized/Galvanneal Steel Coils
1,The zinc layer has uniform thickness and strong adhesion. No
peeling and good corrosion resistance.The Surface is very smooth
and clean,zinc flower is symmetrical,beautiful.
2,Galvanized Coil With the cold rolled steel of different strength
and thickness as substrate, it is produced through applying the
zinc coated on both faces by hot dip process.
3,Large inventory All products are packed and warehousedafter
passing the inspection, and deliveredin one order. So as to ensure
that the customer's products can be delivered in the shortest time.
You don't have to worry about the quality and transportation of the
goods at all.
Application of Hot Dipped Galvanized/Galvanneal Steel Coils
Galvanized steel coils(GI steel coils) can be used for widely as
follows,
(1)In the construction industry: to manufacture exterior and
Interior products such as metal shingles, corrugated sheeting,
sandwich panels, profiles, metallic ceilings, skirting boards,
decorative panels inside heated and non- heated rooms, elevators,
doors window shutters, shelves etc.
(2)In the automotive industry: to manufacture external and internal
car body parts (car doors, car boots, oil filters, dashboards,
windscreen wipers etc.
(3)In manufacture of home appliances, furniture, and consumer
goods: metallic furniture, lighting equipment, shelves, radiators,
сar doors, car boots etc.

Spangle is formed during the hot-dip galvanizing process. The size,
brightness, and surface of spangles mainly depend on the
composition of zinc layer and the cooling method. According to the
size, it includes small spangles, regular spangles, big spangles,
and free spangles. They look different, but the spangles almost
will not influence the quality of galvanized steel. You can choose
according to your preference and purpose.
