Galvanized Steel coil(GI)
Hot dipped galvanized sheet and alloying galvanized sheet have
excellent performance, possessing ideal comprehensive of corrosion
resistance, formation and coating. They are mainly used in
building-roof, door, window, roller shutter door and suspended
skeleton, automobiles-vehicle shell, chassis, door, truck lid, oil
tank, and fender, metallurgy-steel sash blank and color coated
substrate, etc; In electrical appliance, it is mainly for fridge
seat, shell, freezer and kitchen equipment. The company has set up
350,000T/Y continuous galvanizing equipment, with UEC technique and
smoothing, straightening, passivating and coating functions to
produce various galvanized sheets with thickness 0.12-1.2mm and
width 700-1250mm
.

Quality control
• Surface test.
• Salt spray test is srtificial salt spray environment ,simulate
marine climate ,used o check Anti salt spray corrosion performance
of GI and PPGI ,and evaluate the quality of the protective coating
process.
• Flexibility Impact Tester Used to assess catsuit coating at a
very fst deformation ablility to resist cracking or fall out.
• Coating cup drawing tester Used to assess catsuit slow
deformation under coating ability to resist cracking or fall out.
• Zinc layer test
Our Min Zinc and AZ layer is 25g /m2 .We focus on middle and high
quality product only.
Our after-sale Service
We offer Service For 500+customers ,and our products are sold to
over 50+ countries and territories.

Our Product Services
• Cut large coils into small coils or Strip.
For steel coils, we can cut one large steel coil into small steel
coils for loading at seaport; because for container shipping, each
container usually loads weight can not be over 26 tons, but each
large coil is usually about 28 tons, so one large coils has to be
cut into small coils, and because the forklift usually takes 7-10
tons at seaport, so for easy loading into conatiner, each large
steel coil usually is cut into 3 small coils. For bulk vessel
shipping, it usually demands coils weight under 18 tons, so most
times, also need cut one large coil into 2 small coils.
• Open flat coils into steel plate.
For final application, need open flat the coils and cut the coils
into steel plate, so we open flat the coils and cut the coils to
steel plate to the sizes as required. For saving cost for loading
by container, load into 20 feet containers, so cut the length under
5800mm, usually as required to cut to length 2440mm and 5800mm,
width usually be 1220mm and 1500mm.after cutting the steel coils
into steel plate, we can do black paints on the surface of the
plate to make the plate to be anti-rust
