Brief Introduction

1. Prepainted Galvanized Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.

2. The base metal for Prepainted Galvanized Steel Coil is HDGI Steel. The finish coats of Prepainted Galvanized Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.

4. The color of the Prepainted Galvanized Steel Coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.

5. The Prepainted Galvanized Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.

 

Edit

Because there is no after annealing treatment, the hardness is very high (HRB greater than 90), mechanical processing performance is poor, only a simplebending process has less than 90 degree directional (direction perpendicular to the rolled).

3, use three

Edit

Hot rolled products with high strength and good toughness, easy processing and good forming can be excellent performance of welding, which is widely used in ships, cars, bridges, buildings, machinery, boiler, pressure vesselmanufacturing industry.

The scope of application:

(1) after annealing processing into the common cold;

(2) processing galvanized galvanized unit before the annealing treatment;

(3) the basic do not need to process the panel.

4 four, classification

Edit

Carbon steel plate, carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, container plate etc.. Rolling hard volumes: under normal temperature,the hot pickling volumes of continuous rolling.

Hot rolled steel strip products include steel (roll) and the shear of steel plate.And steel (coils) can be divided into straight and finishes volume (the volume,smooth rolling and slitting roll).

Q:What are the reasons for the steel mesh on both sides of the back pouring belt?
Increase overall stability. To prevent cracks due to settlement, uneven cement shrinkage, etc., but also to increase the overall firmness. Generally speaking, the stability of the post casting belt is increased.
Q:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel. Is that correct?
The volume is relatively wide. In addition, flat steel is usually hot-rolled out of long strip steel, fixed length 5 and 5.5,6 meters range, steel coil is Kaiping Chang 12501500, length 2.5 meters, 4 meters, 6 meters, ranging from steel plate
Q:What kind of material does ordinary steel plate refer to in steel market?
And because of the common strength, there is a single carbon steel plate is made, then the internal molecular interactions is very single, which makes the steel in strength is very limited, there is no better development. But the alloy steel plate is different, because this kind of steel plate because has joined many other elements, this also causes its internal molecular structure to become extremely complex, simultaneously its internal molecular force also becomes extremely strong. It also gives the plate greater in strength increased, and the alloying elements of the steel sheet is fixed on the strength of it development is limitless.
Q:What is the difference between hot rolled steel and controlled rolled steel plate? Can two plates be used interchangeably?
It is widely used in hot rolling technology. The utility model has the advantages that the mechanical property of the steel plate is mainly improved by means of control, and the level of the heat treatment plate is achieved. The control plate is included in the hot rolled plate. As for the exchange, mainly depends on your material performance requirements.
Q:Can 16Mn steel plate be used instead of Q345D steel plate?
If the use of Q345D instead of using 16Mn, that can be, but 16Mn instead of Q345D can not, and also can not buy 16Mn steel now, that is the old number, and the latest brand is Q345A
Q:1.5mm galvanized steel prices?
Galvanized steel sheet with hot-dip galvanized or zinc plated surface.
Q:The differences and uses of cold rolling and hot rolling
The free torsion rigidity of hot rolled steel is higher than that of cold rolled steel, so the torsion resistance of hot rolled steel is better than that of cold rolled steel
Q:Why should the back of the steel sheet pile cofferdam be pumped after the construction of the pile cap?
Loading and unloading steel sheet piles should be operated by two points lifting method. The number of steel pile piles should not be too many at any time, and attention should be paid to the protection of the locking hole to avoid damage.
Q:Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
If the intensity is enough, you should be the first 4mm for the economy. Carbon steel plate, with electrode arc welding, 2 diameter welding electrode on line.If it is stainless steel, tungsten argon arc welding is better
Q:What is a fixed length steel plate?
Such as steel plate, its fixed length is six meters, then it is 6 meters, the size will not be uneven. The standard size of the general steel plate is determined according to the national standard, such as 6 meters, 9 meters, etc..
