What should be paid attention to during the processing of color coated steel plate

With the rapid development of modern science and technology, the application of color-coated steel plates is becoming more and more extensive,

which makes us encounter difficulties when choosing to use them.

What style and model are suitable for us to use? Therefore, it is necessary to understand the structure of color-coated steel plates.

Color-coated steel sheets are coils before they form, and there are more models after forming.

Commonly used are 820 types, 840 types, 900 types,s and so on.

His composition structure divide into protective film (now eliminated), polyester paint, galvanized layer, steel plate) cold rolled plate and hot rolled plate).

General engineering use divide into single board and composite board, the composite board divide into asbestos composite board and polystyrene composite board.

The veneers generally use in factories or cooking; some veneers will additionally install with rock wool called “on-site compounding”.

The accessories of the painted board are also indispensable in construction.

Tenderloin, internal corners, external corners, door and window covers, small gutters, expansion joints, etc.

are fixed with rivets and are often sealed with rubber.

The processing of color-coated steel plates should go through processes such as cutting, punching, bending, and joining.

Due to the coating on the surface, special care should be taken to prevent damage to the coating during processing,

which will affect the appearance and service life of the finished product.

What should pay attention to during the processing of color coated steel plate

1. Shearing processing: The burrs on the cutting surface should reduce as much as possible, and the metal powder during the cutting process should remove.

At the same time, a rubber pad should lai on the bottom to prevent the color-coated steel plate from damaging the appearance during stacking and processing;

2. Bending processing: Before processing, the dirt and rust on the stamping die, punches, and other parts should remove;

the temperature during processing should be controlled above 5 degrees Celsius; if rolling processing perform, use hard materials to make rolls (quenched steel, die steel, etc.). )

Or apply a hard inscription on the outer surface of the roller;

3. Pressure processing: When performing pressure processing, the color coating steel plate must carefully select for its base material and coating type;

in addition, it must carefully process, and the appearance of the metal mold must be particularly smooth.

According to the situation, stick a maintenance film on the surface of the color-coated steel plate to maintain the coating;

4. Connection: The color-coated steel plate can mechanically connect, welded, and bonded.

However, the welding equipment and techniques of color-coated steel plates are still in the research and test stage and are not yet mature.

Users should try to use mechanical connection methods.

5. Maintenance of the cut section of the color-coated steel sheet:

When designing the product, try to place the cut-off part in a hidden place; when the galvanized sheet use as the color-coated steel plate of the substrate,

it is usually not necessary to perform special treatment on the cut part, because zinc has some Help to maintain the effect of steel.

Only people who expose to drugs and corrosive gases or who use drugs and corrosive gases in other harsh environments can keep the cut-off part.
