Detailed Description of Color Coated Steel Coil
1. Product Introduction
Color coated steel coil, also known as color coated steel sheet, is made of hot-dip galvanized steel coil or hot-dip aluzinc steel coil as base material. After surface chemical pretreatment, organic paint is roller-coated and baked at high temperature for curing, forming a composite metal building material with beautiful appearance and strong corrosion resistance.
2. Product Structure
Base steel substrate: Ensure mechanical strength and structural stability
Chemical conversion layer: Improve coating adhesion and anti-rust performance
Primer layer: Enhance anti-corrosion ability and buffer external pressure
Top coat layer: Decide color, gloss, weather resistance and service life
Back paint layer: Protect inner side, prevent moisture and oxidation
3. Common Base Material Types
Hot-dip Galvanized Steel (GI): Stable performance, low cost, suitable for inland ordinary construction projects
Hot-dip Aluzinc Steel (GL): Excellent corrosion resistance, 2-3 times longer service life than galvanized sheet, suitable for coastal, humid and high corrosive areas
4. Main Coating Types
PE Polyester Coating: Cost-effective, outdoor service life 5-10 years, widely used in general factory buildings and warehouses
SMP Silicon Modified Polyester Coating: Good hardness and stain resistance, service life 10-15 years, ideal for urban public buildings
HDP High Durability Polyester Coating: Super weather resistance, service life 15-20 years, fit for outdoor photovoltaic projects
PVDF Fluorocarbon Coating: Ultra strong anti-ultraviolet and acid-base resistance, service life over 20 years, used for high-end buildings and coastal engineering
5. Conventional Specification Parameters
Thickness: 0.22mm-2.0mm
Common width: 1000mm, 1200mm, 1250mm, 1500mm
Standard colors: Off white, sea blue, brick red, silver gray, ivory white etc., customized colors available

6. Product Advantages
Double anti-corrosion structure, long service life and stable quality
Light weight, high strength, easy to bend, shear and press forming
Rich colors, bright appearance, good color retention and decorative effect
No secondary painting needed, convenient construction and short construction period
Environmental friendly material, recyclable and energy-saving
7. Wide Application Range
Construction industry: Factory roof and wall, steel structure enclosure, prefab house, color steel sandwich panel
Household appliances: Outer shell of refrigerator, air conditioner, washing machine
Municipal engineering: Construction fence, billboard, warehouse, rolling door
Other fields: Solar support, interior decoration, vehicle interior parts etc.
8. Implementation Standard
National Standard: GB/T 12754-2019 Color Coated Steel Sheet and Strip
9. Purchase Selection Guide
Inland dry area: Choose PE coating + galvanized base material
Coastal rainy corrosive area: Choose PVDF/HDP coating + aluzinc base material
Wall panel: Suggest thickness 0.4mm-0.6mm
Roof panel: Suggest thickness 0.5mm-0.8mm
10. Packaging & Delivery
Adopt standard export packaging with moisture-proof film, paper angle protection and steel belt fastening, waterproof and shockproof.
Normal delivery time: 5-7 working days
