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 is the difference between hard steel plate and soft steel plate?
Molding (Injection) refers to the process of heating and melting material from the high pressure into the mold cavity, after cooling and curing, to obtain forming products. This method is suitable for mass production of complicated parts, and it is one of the important processing methods. The injection molding process can be broadly divided into the following 6 stages: mold injection - pressure holding - cooling - mold opening - product removal, and the process can be repeated to produce products continuously.
Q:Must the welding between steel sheets be opened?
Not necessarily, very thin plate, no opening, but also guarantee penetration, but also through nondestructive testing
Q:What are the functions and classifications of galvanized sheet?
Galvanized sheet mainly used in industry: a large number of galvanized sheet, used in automobile manufacturing, refrigeration, construction, ventilation and heating facilities and furniture manufacturing and other fields. Galvanized steel anticorrosion method becomes important, not only because the zinc can form a protective layer on the surface of iron and steel, but also because zinc has the effect of cathodic protection, when the breakage of zinc coating, it can still prevent iron base metal corrosion by cathodic protection.
Q:Stainless steel plate and steel welding
Can be welded, stainless steel electrodes must be used, but also more than you use the stainless steel plate material, a higher level of welding rod! Before welding, the steel is to be polished to rust. Sub arc welding can also be used
Q:What are hot and cold plates?
Production process: in the production process without heating, so there is no pitting and iron oxide defects often appear in the hot rolling, good surface quality, high degree of finish. Moreover, the cold-rolled products have high dimensional accuracy, and the performance and organization of the products can meet some special requirements, such as electromagnetic properties and deep drawing properties.
Q:Who knows the wire width of the steel mesh?
The general will take the smaller, because this is the amount of processing, product strength. The steel net is placed horizontally, numerical caliper perpendicular to the horizontal plane is measured, (caliper with scale side and parallel to the horizontal plane) JS level width.
Q:What material can be replaced by 345D steel plate?
The steel plate is divided into hot-rolled and cold-rolled parts according to rolling.
Q:What is the hardness of the wear-resistant steel plate?
The microhardness of the wear-resisting layer of the wear-resisting steel plate can reach HVl700 ~ 2000, and the surface hardness can reach HRc58 to 62. The wear-resistant layer of the wear-resistant steel plate is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbides in the metallographic structure are distributed in a fibrous direction, and the direction of the fiber is perpendicular to the surface.
Q:Should the carbon fiber reinforce the steel bar on the side of the beam?
Not necessarily, mainly depends on how the design is calculated, usually put 100~200mm carbon fiber layering
Q:What are the problems encountered in the construction of steel sheet piles? How to deal with
Based on the soft, sometimes the construction was adopted into the adjacent pile phenomenon, measures is the number of adjacent piles are welded together, and in the application of play pile connected locking coated with butter and other lubricants to reduce resistance
