Color steel plate. Pros:
1. Light weight: 10-14 kg square meters, equivalent to 1 30 of a brick wall.
2. Thermal insulation: thermal conductivity of core material: <
3. High strength: it can be used as a ceiling enclosure structure plate to bear load, bending and compression; Generally, there are no beams and columns for houses.
4. Bright color: no surface decoration is required, and the anti-corrosion layer of colored galvanized steel plate is maintained for 10-15 years.
5. Flexible and fast installation: the construction period can be shortened by more than 40%.
Disadvantages: 1. High maintenance cost.
Because the external painting will peel off after a long time, which will affect the appearance, it is generally maintained once every 2 years or so, that is, painting and spraying, but it does not affect the use without maintenance.
2. Poor thermal insulation and sound insulation.
Based on the cost-based design, the general color steel plate mobile house is relatively weak in thermal insulation and sound insulation performance, if you want to improve the heat and sound insulation effect, you need to thicken the partition and partition. The cost will increase.
3. Weak ability to resist wind and snow and pressure.
The general boneless color steel house is relatively weak in terms of compressive capacity, generally only one floor is built, and the skeleton mobile house uses C-shaped steel and I-beam to greatly improve the compressive capacity, but it is generally not recommended for the construction of permanent buildings.
4. It is easy to rust after a long time.
Since it is a steel plate + sprayed material, when the coating is peeled off, the internal steel plate is easy to rust, which affects the use.
Armor plate. Pros:
1. There are many types, and there are many types of steel with different carbon content.
2. High strength.
It is characterized by high tensile, compressive, bending and shear strength. It can be used as a variety of components and components in construction. In reinforced concrete, it can make up for the shortcomings of low tensile, bending, shear and crack resistance of concrete.
3. Good plasticity and toughness.
Construction steel can withstand large plastic deformation at room temperature, and can be cold formed, cold drawn, cold drawn, cold rolled, cold stamping and other cold processing. Steel has high toughness and can withstand impact; It can be welded or riveted for easy assembly; Able to perform, hot rolling and forging; Through heat treatment methods, the properties of steel can be changed or controlled to a considerable extent.
Disadvantages: 1. Low hardenability. Under normal circumstances, the maximum quenching diameter of carbon steel water quenching is only 10mm-20mm.
2. The strength and yield are relatively low. For example, the S of ordinary carbon steel Q235 steel is 235MPa, while the S of low-alloy structural steel 16MN is more than 360MPa. The s b of 40 steel is only, which is much lower than that of alloy steel.
3. Poor tempering stability. Due to the poor tempering stability, when carbon steel is quenched and tempered, in order to ensure higher strength, a lower tempering temperature needs to be used, so that the toughness of the steel is low; In order to ensure good toughness, the strength is low when the tempering temperature is high, so the comprehensive mechanical properties of carbon steel are not high.
4. It cannot meet the requirements of special performance. Carbon steel is often poor in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic properties, etc., and cannot meet the needs of special use performance.

Color steel plate is a kind of steel plate with color coating, and it is also a kind of building decoration material commonly used by us, which is beautifully colored and simple to install, and is widely used in the construction of warehouses and temporary buildings. So what are the advantages and disadvantages of color steel plates, and what are the purchase skills of color steel plates, the following article will introduce it to you.
Advantages of color steel plate.
1. The color steel plate is light in texture, and it also has excellent thermal insulation performance, and its thermal conductivity is still quite good.
2. The strength of the color steel plate is high, and it can be used as a ceiling load-bearing plate, and the bending and compression resistance is excellent.
3. The color steel plate is bright in color, simple and convenient to install, and has excellent decorative effect.
4. The color steel plate has excellent fire resistance, and the surface does not need any decoration.
Disadvantages of color steel plate.
1. High maintenance cost.
Because the exterior of the color steel plate adopts the spray painting and spraying process, it is easy to fall off for a long time, which affects the appearance, and usually needs to be maintained every 2 years, but it will not affect the use effect if it is not maintained.
2. Poor sound insulation performance.
The sound insulation effect of the color steel plate is relatively poor, and the wind resistance and compression resistance are also relatively poor, if you want to high insulation and see the wind and snow effect, you need to thicken the partition and the partition, which will lead to a large increase in the cost of use.
3. It is easy to rust after a long time.
Therefore, the color steel plate is made by spraying the steel plate on the outside, but after the coating falls off, the interior is also prone to rust.
Color steel plate purchase skills.
1. Observe the leakage edge of the color steel plate.
When we buy color steel plate, we need to see whether the exposed section of the color steel plate is finely crystalline, if there is graying, darkening and the existence of a magazine bureau indicates that the quality is poor, if the cut surface crystallization is fine, it means that the quality is excellent.
2. Observe the thickness of the substrate and the thickness of the lamination.
The color steel plate is composed of a base steel plate and a colored peritoneal layer, so we need to pay attention to the thickness of the substrate and the thickness of the coating when purchasing. 3. Listen to the sound.
When we buy color steel plates, we can also use our fingers or hard objects to tap the color steel plates, listen to the sound, usually the sound of the color steel plate with excellent material is relatively bright and crisp.
