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's the best way to open a 10mm thick steel sheet?
Sheet steel is produced by hot rolling or cold rolling, with steel plates between 0.2-4mm in thickness. The width of the steel plate is between 500-1400mm. According to different uses, the thin steel plate is rolled with different material billets. The materials are carbon steel, fine carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel and electrical silicon steel. They are mainly used in automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and so on. In addition to the direct delivery of rolled steel sheets, there are also kinds of pickling, galvanizing and tinning.
Q:Why can steel HPB300, steel plate without Q300, steel structure manuscript review, but also continued the Q235, why not improve it?
Carbon steel according to the steel yield strength is divided into 5 grades: Q195, Q215, Q235, Q255 and Q275 of each grade because the quality is divided into A, B, C, D grade, with a maximum of four kinds, some only one; this is just plain carbon steel, the price is cheap, generally not heat treatment. Only quality carbon steel has the value of heat treatment.
Q:What can be painted on galvanized steel sheet?
Paint matching1. The paint preparation system used for galvanized steel in soaking or humid environment must be alkali resistant and can not be saponified. Therefore, it is advisable to choose epoxy type coating. Best with epoxy zinc yellow primer.2, for exposure in the dry environment of galvanized steel, zinc yellow epoxy primer can be used with acrylic polyurethane topcoat, or intermediate epoxy zinc chromate primer + epoxy micaceous iron oxide + fluorocarbon topcoat with ultra weatherability, long service life of the supporting scheme.In short, surface treatment is very important, considering the durability of galvanized parts, it is recommended to use the above two kinds of matching paint to ensure the normal service life and reduce the cost of intermediate maintenance.
Q:What does "rolled steel" mean?.
Rolling is a rolling process, the plate is kind of calendering material, not only some specific material, it can contain stainless steel and carbon steel materials, stainless steel with thickness of steel production for example, now the tolerance basic law, but in order to achieve a certain thickness
Q:How to choose welding method for welding different plate and thick steel plate?
Plate groove, the groove thickness is less than or equal to the thickness of the sheet, the welding arc to a plate, the molten pool of molten iron melt sheet, the specific point of view of plate thickness difference, observe the molten pool adjust current, prevent sheet welding, double-sided welding when necessary.
Q:Can the steel surface be made of epoxy resin flooring?
According to the characteristics of epoxy resin, it should be possible
Q:Who knows the wire width of the steel mesh?
Steel net is diamond, respectively from the left and right (up or down) with two curved metal strips, the two metal strips are generally not the same thickness, the thickness is the stem width, the width is less than the thickness of material.
Q:What welding rod should be used for welding of cast iron and Q235B steel plate?
Q235B is a kind of low carbon steel commonly used in China, good welding performance, applicable to a variety of welding engineering used J422 (new brand E4303) in order to improve the efficiency of welding, and can also be used CO2 welding, welding wire can be used H08.
Q:What is the difference between hot rolled steel and controlled rolled steel plate? Can two plates be used interchangeably?
The rolled steel plate is used to achieve the ideal special performance by controlling the amount of deformation, deformation and temperature. Having higher added value and higher price. Interchangeable, but not a good choice!
Q:What is a die steel plate?
Pressure plate template is made of galvanized steel sheet or the antiseptic treatment, the machine rolled into a groove plate with a cross section of the ladder waveform or project template material open box steel shell.
