Specification, type and characteristics of color steel coil

Color steel coil is a commonly used building material in construction. In order to meet the needs of different sites, the coil has many specifications in the market. If we want to choose and use this building material more skillfully, we need to have a detailed understanding of its various specifications and parameters. The following is a detailed introduction to this problem, you can learn about it.

1. The thickness of color steel coil is 0.13MM or 0.7mm, and the thicker coil needs to be customized.

2. The zinc coating amount is 381g / m Λ 2, and the coating thickness is 5 ~ 25 μ m。

3. Rock wool board, which is widely used as core material, has the following main properties: volume weight 100 ~ 150kg / m Λ 3, thermal conductivity (w / m Λ 2K) 0.032 ~ 0.040.

4. The working temperature is - 268 ~ 700 ℃, and the fiber softening temperature is 900 ~ 1000 ℃.

5. The weight of color steel coil is 10-14kg / m2, which is equivalent to 1 / 30 of brick wall.

After knowing the specifications of the above color steel coil, we can choose the appropriate color steel coil according to our own use situation, so that it can play its due role in the processing and production of architecture, decoration, household appliances, furniture, etc.

Color coated substrate type

Cold rolled color coated steel plate

The color plate produced by the cold-rolled substrate manufacturer has a smooth and beautiful appearance and has the machinability of the cold-rolled plate. However, any small scratch on the coating surface will expose the cold-rolled substrate to the air, resulting in the rapid formation of red rust. On bare iron. Therefore, these products can only be used for temporary isolation measures with low requirements, and can only be used as indoor materials.

Hot dip galvanized color coating roll

The product obtained by coating organic coating on hot-dip galvanized steel plate is hot-dip galvanized color coated plate. In addition to the protection of zinc, the organic coating on the surface of hot-dip galvanized color coated plate also plays the role of isolation and rust prevention, and its service life is longer than that of hot-dip galvanized plate. The zinc content of hot-dip galvanized substrate is generally 180 g / m2 (double-sided). The zinc content of hot-dip galvanized substrate for outdoor use is 275 g / m2.

Hot dip galvanized color coating roll

According to the requirements, hot-dip aluminum zinc steel plate can also be used as color coated substrate (55% aluminum zinc and 5% aluminum zinc).

Galvanized color coated plate

The galvanized sheet is used as the bottom plate and baked with organic paint. The product is galvanized color coated sheet. Due to the thin zinc layer of galvanized sheet, it usually contains 20 / 20g / m2 zinc, which is not suitable for the production of outdoor wall and roof. However, due to its beautiful appearance and excellent processing performance, it is mainly used for household appliances, acoustics, steel furniture, interior decoration and so on.
