Product Description
Galvanized coil is produced by continuous hot-dip galvanizing process using hot-rolled steel strip or cold-rolled steel strip as substrate. Hot-dip galvanized sheets are supplied in rectangular flat sheets after cross-cutting; hot-dip galvanized coils are supplied in coils after coiling.
Galvanized steel coil is one of the hot-selling products of Delong Metal. It is available in big, regular, small, and zero spangles. Compared to color steel coil, it is more affordable. Hot-dip galvanized coils are mainly used in containers, home appliances, automobiles, transportation, home business, construction and other fields. Especially in automobile manufacturing, steel structure construction, steel silo manufacturing and other industries. Their main features are: good surface quality, strong corrosion resistance, benefit from deep processing, economical and practical, etc.
As a wholesale supplier, Delong Metal can meet bulk orders timely. Also, we will offer a direct-sale price to lower your cost. If you are interested, please contact us for details

Spangles
Spangle is formed during the hot-dip galvanizing process. The size, brightness, and
surface of spangles mainly depend on the composition of the 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 use purpose.
(1) Big or Regular Spangles
Spangle-promoting elements are added to the zinc bath. Then beautiful spangles are
formed as the zinc layer solidifies. It looks good. But the grains are coarse and there is
slight unevenness. In a word, its adhesion is poor but weather resistance is good. It is
most suitable for guardrail, blower, duct, rolling shutter, drain pipe, ceiling bracket, etc.
(2) Small Spangles
During the solidification process of the zinc layer, zinc grains are artificially restricted to
form as fine spangles as possible. The spangle size can be controlled by cooling time.
Generally, the shorter the cooling time, the smaller the size. Its coating performance is
great. Therefore, it is perfect for drainage pipes, ceiling brackets, door columns, the
substrate for color coated steel, car body panels, guardrails, blowers, etc.
(3) Zero Spangles
By adjusting the chemical composition of the bath, the coating has a uniform surface
without visible spangles. The grains are very fine and smooth. It has excellent corrosion
resistance and good coating performance. It is also ideal for drainage pipes, automobile
components, back panels for home appliances, automobile body panels, guardrails,
blowers, etc.
Galvanized coil features lightweight, aesthetics, and excellent corrosion resistance. It
can be used directly or as the base metal for PPGI steel. Therefore, GI coil has been a
new material for many fields, such as construction, shipbuilding, vehicle manufacturing,
furniture, home appliances, etc.
1. Construction
They are often used as roofing sheets, interior and exterior wall panels, door panels and
frames, the surface sheet of the balcony, ceiling, railings, partition walls, windows and
doors, gutter, sound insulation wall, ventilation ducts, rainwater pipes, rolling shutters,
agricultural warehouses, etc.
2. Home Appliances
GI coil is widely applied to home appliances, such as the back panel of air conditioners,
and the outer casing of washing machines, water heaters, refrigerators, microwave
ovens, switch cabinets, instrument cabinets, etc.
3. Transportation
It is mainly used as decorative panels for cars, corrosion-resistant parts for cars, decks
of trains or ships, containers, road signs, isolation fences, ship bulkheads, etc.
4. Light Industry
It is ideal for making chimneys, kitchen utensils, garbage cans, paint buckets, etc. At
Wanzhi Steel, we also make some galvanized products, such as chimney pipes, door
panels, corrugated roofing sheets, floor decks, stove panels, etc.
5. Furniture, such as wardrobes, lockers, bookcases, lampshades, desks, beds,
bookshelves, etc.
6. Other Uses, such as post and telecommunication cable, highway guardrails,
billboards, newsstands, etc.
