● Printed/Embossed coated coils are products that impart decorative patterns or three-dimensional textures to traditional coated coils through special surface treatment processes.
● Printed Color Coated Sheets employ advanced digital printing or roller coating transfer technology to reproduce exquisite patterns like wood grain, stone texture, camouflage, and geometric designs with high precision on the panel surface. They retain the corrosion resistance and durability of standard coated sheets while excelling in decorative appeal. They can accurately meet various architectural aesthetic needs, achieving realistic visual effects and providing diverse artistic expression for building facades and interior spaces.
● Embossed Color Coated Sheets are created by pressing strongly three-dimensional textures (e.g., orange peel, diamond pattern) onto the surface using specially designed embossing rollers before the coating fully cures. This process not only enhances the visual texture and tactile feel but also effectively conceals substrate imperfections and scratches that may occur during fabrication and installation, significantly improving the product's durability and practicality.
● Together, these two product types complement each other and are widely used in large commercial centers, stadiums, high-end residences, and custom furniture, serving as ideal materials for imparting unique character and enduring aesthetic appeal to buildings.
Same as conventional coated coils, depending on the mechanical and corrosion resistance requirements of the final application.
Substrate Type
Galvanized Steel (GI)
Galvalume Steel (GL) - More common.
Substrate Thickness
Conventional Range: 0.3mm ~ 1.2mm
Common for building interiors/appliances: 0.4mm ~ 0.8mm
Coating Weight
Selected based on requirements.
e.g., GI: 90/90, 75/75; GL: 50/50,75/75；
This is the core of the printed/embossed coated coil.
Coating System
Primer + Topcoat (+ Print Layer)
Primer + Topcoat + Embossing
Resin System: Polyester (PE), High Durability Polyester (HDP), Silicone Modified Polyester (SMP), PVDF. PE is common for interiors; HDP or PVDF is required for exteriors.
Coating Thickness
Unit: μm, per side.
Conventional Requirement: ≥ 20μm - The coating for embossed coils must be thicker to accommodate the pattern depth.
Pattern Type - Core Parameter
Print Patterns:
Wood Grain
Stone Pattern
Abstract Pattern
Camouflage
Custom Design
Embossed Patterns:
Orange Peel
Leather Grain
Pebble
Linen
Brick / Masonry
Pattern Precision & Quality
Print Resolution: The clarity and detail of the pattern.
Embossing Depth: Typically 10μm ~ 50μm. Depth affects tactile feel and visual effect.
Pattern Uniformity: The consistency of the pattern across the entire coil.
Color & Gloss
Color: Customizable, printing can achieve multi-color complex patterns.
Gloss: Typically Matte or Low Gloss (10° - 40°) to better highlight texture and hide minor scratches.
Pattern Durability
Abrasion Resistance: For printed coils, the pattern must have good adhesion and not be easily worn off.
Scratch Resistance: The 3D texture of embossed coils helps to conceal scratches.
QUV Accelerated Weathering Test: For outdoor use: ≥ 600 hours (HDP) or ≥ 1500 hours (PVDF) without significant deterioration of color and pattern.
Chemical Resistance
Resistance to alcohol and cleaner wiping, especially for appliance panels or indoor furniture.
Physical & Mechanical Properties
Adhesion: Cross-Cut Test Class 0 or 1, crucial for the print layer.
T-Bend: 3T - 5T, embossing/printing may slightly affect flexibility.
