Shanghai Huiyi International Co., Ltd.

1- Hot Rolled Steel Coils Mill

Adopted many new steel rolling technologies and automatic cooling line, the two hot rolled

steel coil production lines are with annual output of 2000 tons, which can supply high quality

hot rolled steel coil to meet customer’s demand. And with six accessory slitting machines,

the product width can be multi-choice from 0.11mm to 6.0mm.

2- Cold Rolled Steel Coils Mill

The whole equipment technologies are based on advanced techniques of steel cold rolling

processing, fluid pressure sensing, electronic controlling etc. There are two pickling lines

with annual production of 1.3 million tons, three cold rolling production lines with annual

production of 5000 tons. The thickness range is from 0.12mm to 2.00mm.

3-Hot Dipped Galvanized Steel Coils Mill

Specializing in the production of Hot-dip Galvanizing steel coils and related products. The

annual capacity of this Continuous Hot-dip Galvanizing Lines which adopted the modified

Sendzimir method can reach 12000 tons. It can produce 0.11-6.0mm thick cold (0.12-2.0mm)

or hot(0.11-6.0mm) rolled galvanized steel coils with 700-1500mm width. These lines are

equipped with skin pass mill and can produce galvanized steel coils of regular spangle and

minimized spangle with different specifications like CQ, SQ, FH and so on. The zinc coating

is from 20g / m2 to 600g / m2. The lines can deal with various surface passivation treatment

such as chromated, chromated with anti-finger or chrome free with anti-finger, chrome free,

and trivalent chromium passivation, etc.

4-Pre-painted Steel Coils Mill

Pre-painted steel coil equipments with high quality are mainly imported from U.S.A, Japan,

and Taiwan. The designed capacity of the line is 60,000 tons per year. It takes advantage

of American GFG coating system and the process of two coating and two baking. And one

tension leveler was adopted in the exit side; therefore, high quality Pre-painted coils could

be produced. Color coated products are widely applied to roof, outside wall, rolling door,

sandwich plate, ceiling, daylight lamp manostat, antistatic and dustproof furniture plate, white

board, and self-cleaning plate, etc. And we also have a professional processing center for

slitting and flattening the thin gauge. Designed capacity is 600, 000 tons per year. There are

six imported processing lines which are all high-precision slitting equipments.

5- Hot Dipped Galvanized Steel Strips Mill

Highly advanced GI facility, specialized in producing Hot dipped galvanized steel strip

240,000MT annually. The continual hot roll steel strip in coil is made into galvanized steel

strip in coil by means of passing through the molten zinc pot. Its uniformity, tightness, erosion

resistance and pressure resistance characterize the coating on the product surface. In addition,

the strength of the welding seam is satisfied. The thickness from 0.11mm to 6.0mm, and width

under 1600mm. The Zinc coatingis from Z20 to Z600.

6-Cold Rolled Steel Strips Mill

Specialized in producing Cold rolled steel strip 12,000MT annually, the major facility

including 350, 450, 650,850 cold-rolled steel strip reversible and continuous rolling mills,

800HC rolling machine,5 acid-washing production line, auto-control slitting machine vertically

and horizontally, 10 sets of batch annealing facility, 2 continuously black annealing lines,

ammonia decomposition, stove of arising coal gas.

For each order, HUIYI would stick to follow with the quality guarantee system, from getting order→confirm raw material→specification analysis→manufacturing→process control inspection→packing finish →shipment, in order for 100% satisfaction from our customers.
