Factory Making 4140 Alloy Steel Plate - Theoretical Knowledge of Color Steel Plate – XINXIN PENGYUAN

The difference between plastic steel and plastic steel lies in the composition of the material. The magnet can absorb. Strictly speaking, plastic steel and color steel cannot be well distinguished in terms of metal properties and surface treatment, because be the same in essentials while differing in minor points. Six characteristics of color steel plate:

1. Light weight: 10-14 kg / m2, equivalent to 1/302 of brick wall.

2. Thermal insulation: thermal conductivity of core material: λ<= 0.041w/mk. 

3. High strength: it can be used as the bearing plate of ceiling enclosure structure, bending resistance and compression resistance; Beams and columns are not used in general houses.

4. Bright color: no surface decoration is required, and the preservation period of the anticorrosive coating of colored galvanized steel plate is 10-15 years.

5. Flexible and fast installation: the construction period can be shortened by more than 40%.

6. Oxygen index: (OI) 32.0 (provincial fire product quality inspection station).

7. The form of color steel plate: it is coiled material before forming, and there are many models after forming.

8. The most commonly used ones are: 820, 840, 900! Its composition structure is: protective film, polyester paint, zinc coating, steel plate.
