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:Steel plate pile length, adjacent two steel plate pile joints should be staggered what position?
If the joint in the same position, such as 9+9m then need to stagger joint position,Avoid stress in one position that results in joint fracture and deformation risk.
Q:What's the difference between single rolling steel sheet and continuous rolling steel plate?
Continuous plate refers to the hot rolling and cold rolling steel plate, rolling steel in rolling end is rolling roll, after Kaiping became a continuous plate after segmentation, due to the presence of curling and Kaiping rolling steel process, usually there are some residual stress, usually thin (less than 25mm) is narrow (usually below 2100mm).
Q:What's the difference between a spray plate and a colored steel plate?
Color steel plate, material without zinc flower leveling, hot galvanized steel coil and zinc alloy coating, steel coil and other good substrate;
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 is Larson steel sheet pile?"
As a kind of new building materials in the Larson steel sheet pile cofferdam, bridge construction, large pipeline, temporary ditch excavation for retaining, retaining water and sand retaining wall; in the wharf, unloading field wall, retaining wall, Levee Revetment, play an important role in engineering. As a cofferdam, Larson steel sheet pile is not only green and environmental friendly, but also has fast construction speed, low construction cost and good waterproof function.
Q:How to introduce carbon steel plate?
Grade: the cases of Q235-A F, said the sigma s Note: Q is more than 235MPa grade yield strength of A grade (ABCD four), F boiling steel characteristics: low price, process performance (such as welding and excellent cold formability). Applications: general engineering structures and general mechanical parts. Such as Q235 can make bolts, nuts, pins, hooks and less important mechanical parts, as well as the construction of the thread steel, steel, steel and so on
Q:What's the density of the 0.5 color steel plate?
The traditional coating is divided into several categories, the most high-grade is fluorocarbon coating, almost 20 years of anti-corrosion. Generally from the steel mill to reel in the form of distribution to all parts.
Q:Can the steel surface be made of epoxy resin flooring?
According to the characteristics of epoxy resin, it should be possible
Q:What are the rental costs for steel sheet piles?
According to the different processing technology, it can be divided into hot rolled / stretched steel sheet pile and cold rolled steel sheet pile. Now, due to the production conditions and scale constraints, hot rolled steel sheet pile has no production line in China, and the rolled steel sheet piles used in China are all from abroad.
Q:How can steel plates with a thickness of 1MM be welded?
The seam is also called the wheel welding equipment for the production, mainly uses fuel exhaust pipe seal. The principle is similar to that of spot welding. The difference is that the output current is uninterrupted.
