Product Description:

 PPGI is the material which uses galvanizinc color steel striped steel as the basic substrate metal.There could be other substrates such as aluminium,aluminium zinc color steel stripinc,stainless steel,etc. Prepainted galvanizinc color steel striped steel coil refers that after the surface pretreatment of base plate, covering one layer or two layers(more than two layers when necessary) organic coating on the surface with the method of continuous coating,and then conduct drying and solidifying. Prepainted galvanizinc color steel striped steel coil is characterizinc color steel striped of excellent decoration,moldability,corrosion resistance,strong coating adhesive force and can keep the novel luster for a long time.

 


PPGI surface can be divided into coated board, embossed board, printing plate.

Q:What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
General handling steel rolls are used for driving. Forklift trucks are OK, but a larger fork truck, usually cold rolled, weighs less than 15T. The hot rolled coil is below 30T.
Q:Steel coil from vertical to horizontal, what sling needs?
Consider using the function with hydraulic prop hanging clamp from the coil center will hold tight after hanging up, then put in a L type hydraulic turnover device platform or unilateral double column loading platform, then L platform can realize 90 degrees down, vertical horizontal variable.
Q:What is the material of steel coil 08F and what brand can be used instead?
20 steel used for various mechanical parts is not subjected to great stress and toughness, such as rod, sleeve, screw, lifting hook; also can be used for manufacturing in 60 pressure and 450 DEG C using non corrosive medium pipes, pipe; can also be used for carbon and cyanide carburized core strength is not the chain, such as bushings, roller, shaft and gear, sprocket and other important.
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
As far as I know, the galvanized rolls of WISCO are wider in width than other domestic steel mills, and can produce 2080 wide steel coils.
Q:The difference between aluminized color steel roll and ordinary color steel roll
Aluminized color coated sheet is a new type of material produced in China in recent years due to its high end applications. It is often used as an indication of CCLI. It is made of galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon), which is more galvanized and more corrosion resistant. It is processed by surface degreasing, phosphating and complexing treatment, and is coated with organic coating.
Q:Several reading methods of steel tape measure
Precise steel tape factory and after a period of time must go through the verification and indicate the verification of temperature, tension and feet. Feet marked on the length of its nominal length, and the difference between the actual length is called length correction delta l ruler by different tension will make feet long. To avoid this change requires the use of steel tape according to the scale mark force of steel tape. At different temperature the foot will change with the temperature so it is necessary to use t as variable function to represent the feet long, this is the ruler length equation, its general form:
Q:Why can hot rolled coils be placed outside?
Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
Q:Can cold rolled galvanized steel coils be acid washed after oxidation?
If it has been galvanized, it can not be pickled, and if it is pickled, it may corrode the zinc layer
Q:What's the best material for color coated steel coil?
The base material of color coated coil is mainly galvanized steel or galvanized alloy steel plate.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
Generally, according to the volume measurement, each roll weighs 3~15 tons.
