According to its topcoat coating, the color-coated steel plate is classified mainly into PE polyester color plate, PVDF fluorocarbon color board, HDP high weather-resistant polyester color plate (also called high-performance polyester color board), SMP silicon color change board. Here is an introduction to the performance characteristics, service life, application fields and comparison of different coated color plates.

1PE polyester color board

Introduction: Polyester color coating is a metal paint color plate made by using PE polyester paint coating on the metal plate, and then baking at high temperature

Main features: good adhesion, wide range in formability and outdoor durability, medium chemical resistance.

Specifications: thickness 0.17-1.5mm, width below 1250mm.

Substrate: galvanized/aluminum-zinc.

Coating structure: 2 layers on the front / 1 layer on the back.

Coating thickness: 15-25um/5-10um

Coil weight: less than or equal to 10 tons.

Roll inner diameter: 510mm/610mm.

Roll outer diameter: 800-1500mm.

Service life: 5-10 years

Application fields: light steel structure industrial plants, warehouses, mobile houses, civil residences, flat slope roofs, etc.

2SMP silicon modified color plate

Introduction: Silicon modified color coating is a metal paint color plate made by using SMP silicon modified resin coating on a metal plate, and then baking at high temperature

Main features: The coating film has good hardness, abrasion resistance and heat resistance, as well as good external durability and non-chalking, but limited gloss retention and flexibility.

Specifications: thickness 0.17-1.5mm, width below 1250mm.

Substrate: galvanized/aluminum-zinc.

Coating structure: 2 layers on the front / 1 layer on the back.

Coating thickness: 20-25um/5-10um

Coil weight: less than or equal to 10 tons.

Roll inner diameter: 510mm/610mm.

Roll outer diameter: 800-1500mm.

Service life: 10-15 years

Application fields: light steel structure industrial plants, warehouses, mobile houses, civil residences, flat slope roofs, etc.

3HDP high-performance color board

Introduction: High-performance color coating, also known as high weather-resistant color plate, is the use of HDP high-performance polyester coating on the metal plate, and then baked at high temperature to make the metal paint color plate.

Main features: Due to the different resin molecular structure of high-performance polyester and ordinary polyester, high-performance polyester has better resistance to ultraviolet damage and better durability, and its main properties are between polyester and fluorocarbon

Specifications: thickness 0.17-1.5mm, width below 1250mm.

Substrate: galvanized/aluminum-zinc.

Coating structure: 2 layers on the front / 1 layer on the back.

Coating thickness: 20-25um/5-10um

Coil weight: less than or equal to 10 tons.

Roll inner diameter: 510mm/610mm.

Roll outer diameter: 800-1500mm.

Service life: 10-15 years

Applications: It is suitable for light steel structure buildings with high requirements for UV resistance, flat and sloped roofs, etc.

4PVDF fluorocarbon color plate

Introduction: Fluorocarbon color plate is a metal paint color plate made by using PVDF polyvinylidene fluoride coating on the metal plate, and then baked at high temperature.

Main features: It has extraordinary stability, and can maintain the stability of various properties in acid, alkali and polluted environments; Excellent durability, fluorocarbon color board can still maintain good color and luster outdoors for 20 years; Excellent processing performance, the painted color plate has high flexibility, impact resistance, and can also be post-embossed.

Specifications: thickness 0.17-1.5mm, width below 1250mm.

Substrate: galvanized/aluminum-zinc.

Coating structure: 2 layers on the front / 1 layer on the back.

Coating thickness: 20-25um/5-10um

Coil weight: less than or equal to 10 tons.

Roll inner diameter: 510mm/610mm.

Roll outer diameter: 800-1500mm.

Period of use: 20 years or more

Applications: It is suitable for chemical plants, power plants, steel mills, high-speed rail stations, etc. with high requirements for ultraviolet resistance and weather resistance.
