When it comes to the classification of pressure-type color-coated rolls, many friends only know the tile type classification or thickness classification or color classification, but if it is more professional to talk about the paint film coating classification of pressure-type color-coated rolls, I estimate that a large number of friends will scratched his head.

The paint film coating of the embossed color coating steel roll is divided into four kinds: ① polyester coating (PE) color coating; ② high durability coating (HDP) color coating; ③ silicon modified coating (SMP) color coating board; ④ fluorocarbon coating (PVDF) color-coated board;

1. Ester coating (PE) color coated steel coil/sheet

PE polyester color-coated steel sheet has good adhesion, rich color, wide range in formability and outdoor durability, medium chemical resistance, and low cost. The advantages of PE polyester color-coated board are mainly cost-effective, and it is recommended to use PE polyester color-coated board in a relatively friendly environment;

2. High weather resistance coating (HDP) color coated steel coil/sheet;

HDP high weathering color coated steel coil/sheet has excellent color retention and anti-ultraviolet performance, excellent outdoor durability and chalk resistance, good paint film coating adhesion, rich colors, and excellent cost performance. The most suitable environment for high-weather-resistant HDP pressure-type color-coated rolls is harsh weather environments, such as plateaus and other areas with strong ultraviolet rays, we will recommend the use of HDP high-weather-resistant pressure-type color-coated rolls;

3. Silicon modified coating (SMP) color coated  steel coil/sheet;

The hardness, abrasion resistance and heat resistance of the SMP silicone polyester color-coated steel plate coating film are good; as well as good external durability and chalk resistance, gloss retention, general flexibility, and moderate cost. The most suitable environment for SMP silicon-modified polyester embossed color-coated coils is high-temperature workshops. For example, steel mills and other environments with high indoor temperatures are generally recommended to use SMP silicon-modified polyester embossed color-coated coils;

4. Fluorocarbon coating (PVDF) color coated steel coil/sheet;

PVDF Fluorocarbon Color Coated Steel Sheet has excellent color retention and UV resistance, excellent outdoor durability and chalk resistance, excellent solvent resistance, good formability, dirt resistance, limited color, and high cost. The high corrosion resistance of PVDF profiled color-coated coils. Many workshops with strong corrosive environments will choose PVDF profiled color-coated coils, and there are often humid sea breezes at the seaside, which are more corrosive.

Specifications of color steel plate

Color coated galvanized steel coil is a commonly used building material in construction. In order to meet the needs of different sites, there are many specifications of the coil on the market. If we want to choose and use this building material more proficiently, we need to have a detailed understanding of its various specifications and parameters. The following describes this issue in detail for everyone to understand.

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

2. The amount of zinc coating is 381g/m∧2, and the coating thickness is 5-25μm.

3. The core material is widely used rock wool board, and its main properties are as follows: the bulk density is 100～150kg/m∧3, and the thermal conductivity is (W/m∧2 k) 0.032～0.040.

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

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

After understanding the specifications of the above color steel coils, we can choose the appropriate color steel coils according to our own use conditions, so that they can play their due role in the processing and production of construction, decoration, home appliances, furniture, etc.
