  • PPGI (ISO 9001:2000)

  • Width: 914 to 1,250mm

  • Thickness: 0.14 to 1.0mm

  • Zinc coating: 50 to 180g

  • Color coated steel sheets are a new-type pre-coated steel product developed rapidly in the past  years

  • Color coated steel sheets are made on high-speed continuous coating lines through a number of processes such as chemical pretreatment, primary coating and finish coating, thus they have better coating quality than single piece coating

  • They are ideal substitutes for wood panels in the construction industry because of their good economic features such as convenient installation, conservation of energy and resistance to contamination

  • The rapid development of color coated steel sheets is mainly attributed to their good economic, social and environmental properties

Q:What are the differences between strip steel and round steel? Where are they mainly used?
Difference between round bar and other steel bars:(1), is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed, cohesive force that cause steel and concrete, and the bond strength of steel and concrete in the other.(2) the composition is different. Round steel (grade a steel) belongs to ordinary low carbon steel, and most other steel bars are alloy steel.(3), the strength is not the same, low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
Q:What is the difference between strip and coil?
Coil generally refers to the strip width not less than 600mm, can generally be divided into Kaiping steel plate or longitudinal strip, standard and plate together, such as: carbon and low alloy structural steel plates and strips. Strip width is generally less than 600mm.
Q:What's the meaning of "double light" in strip cold rolling?
Double light: This is generally cold rolled roll of the statement, cold-rolled grades SPCC, SPCC is generally a general term, including SPCC-SB, SPCC-SDSPCC-SD is a single light, it is now generally rough surface is the material directly labeled SPCC, remove the suffixSPCC-SB is double light, the surface is mirror surface, also called bright surface
Q:Hot rolled strip and hot rolled strip are also sealing plates? What's their function?
Secondly, strip and steel strip should be about the same, no less than a narrow strip of steel bar, the equipment configuration is the same
Q:The degreasing time is too long, will the strip surface be oxidized?
Sheet metal pretreatment, degreasing total alkalinity is recommended in 15-20, alkali spent large, must be short time processing, for a long time will make the metal crystal nucleus passivation, influence phosphating film. Sheet metal general oil should not be cleaned, especially stamping parts, etc., it is recommended to use degreasing temperature, the temperature can be 65-75 degrees.
Q:What is the difference between steel strip and coil?
What do you think of rolling mills, not money ah, rolling strip is a small rolling opportunities, can be cheaper than rolling coil, and this cost should be spread to each product above, there are other what, like the cost of sharing ah.
Q:65 what is the hardness of the best heat treatment of manganese steel strip?
65 manganese spring steel best heat treatment hardness, mainly to have good elasticity, in the dynamic load environment conditions, there is a high yield strength. In case of heavy load, there should be high fatigue strength. Under repeated loads, it has a long service life, and has sufficient toughness and plasticity to prevent sudden brittle fracture under impact. 65 the best heat treatment hardness of manganese steel strip is HRC48, and the above comprehensive mechanical properties are the best.
Q:What is the meaning of C hot strip material, B material is how to distinguish between
Due to work hardening of cold rolled steel plate, a certain degree of toughness is low, but can yield better than that used to cold spring piece parts, at the same time as the yield point is close to the tensile strength, so the use of risk is not predictable, prone to accidents in the load exceeds the allowable load.
Q:What is the difference between steel strip and strip steel?
The steel strip is the product which the processing enterprise cuts the strip steel according to the specific machine size to cut into a certain length, the width, generally assumes the enclosed circle shape. For example, steel conveyor belts, such as furniture or wood processing enterprises, "band saw" saw blade, but also steel band.
Q:Pickling process of cold rolled strip
The continuous pickling line is divided into 3 sections according to the nature of the work:Inlet section: feeding, unwinding, strip surface, iron oxide crushing, straightening, shearing, shearing and welding;Pickling section: acid washing, hot and cold washing and drying;Exit section: shearing, oiling, and final take-up (take-up).
