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 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
