Product Introduction
Overview
The High-Quality Prepainted Steel Sheet is a premium metallic material designed to meet the dual demands of aesthetic appeal and functional durability. Constructed with a galvanized (PPGI) or galvalume (PPGL) steel substrate, this sheet features a pre-applied polymer coating in a wide range of colors and finishes, eliminating the need for on-site painting. The manufacturing process integrates precision surface treatment, primer adhesion promotion, and topcoat application, ensuring uniform color distribution and long-term resistance to environmental factors.
Available in thicknesses from 0.15mm to 2.0mm and widths up to 1250mm, the sheet balances formability with corrosion resistance. The prepainted surface can be customized with polyester, silicone-modified polyester (SMP), or polyvinylidene fluoride (PVDF) coatings, catering to diverse application requirements from indoor appliances to outdoor architectural cladding.
Features
Polyester Coating: Offers cost-effective color retention and general weather resistance, suitable for moderate climates (10-15 year warranty).
SMP Coating: Enhances heat and chemical resistance, ideal for industrial environments with mild pollution.
PVDF Coating: Provides exceptional UV and corrosion resistance (20+ year warranty), recommended for coastal or high-temperature zones.
Precision Surface Finish: Smooth, defect-free surface enables high-quality printing, embossing, or direct use in visible applications, such as signage and furniture.
Excellent Formability: Maintains ductility after painting, allowing complex bending, stamping, and roll-forming without coating cracking—critical for automotive and appliance manufacturing.
Efficient Installation: Lightweight design reduces transportation and labor costs, while pre-cut sizes and compatibility with standard fasteners streamline construction processes.
Environmental Compliance: Lead-free, low-VOC coatings meet international standards (RoHS, REACH), supporting sustainable building certifications (LEED, Green Globes).
Application
Building Envelopes: Used for cladding, roofing, and partition walls in commercial complexes, residential towers, and industrial facilities, offering design flexibility with color-matching options.
Home Appliances: Forms panels for refrigerators, washing machines, and air conditioners, where consistent color and scratch resistance enhance product appeal.
Transportation Industry: Fabricates truck bodies, trailer skins, and railway carriage components, resisting road salt, UV radiation, and mechanical stress.
General Fabrication: Ideal for metal furniture, storage cabinets, and signage, providing a durable, pre-finished material that reduces post-processing steps.
FAQ
Q: Can I request a custom color not in the standard palette?
A: Yes, we offer bespoke color matching services, including Pantone or RAL shades, with a minimum order quantity of 50 tons for non-standard hues.
Q: How does the coating handle scratches during installation?
A: Minor scratches can be touched up with matching paint; for high-impact environments, consider upgrading to a scratch-resistant PVDF topcoat.
Q: Is this sheet suitable for outdoor use without additional protection?
A: Yes, the prepainted coating is designed for outdoor exposure, but longevity depends on the coating type—PVDF is recommended for harsh climates.
Q: Can it be recycled at the end of its life?
A: Absolutely—the steel substrate and coatings are 100% recyclable, with no hazardous materials compromising the recycling process.
Color coating production process
Coating Type of PPGI & PPGL
Polyester (PE):Color coated steel coils are valued for their excellent adhesion, vibrant color options, and extensive formability, making them suitable for a variety of design possibilities. With exceptional outdoor durability, these coils can withstand harsh weather conditions while maintaining their aesthetic appeal. Additionally, they offer moderate chemical resistance, further enhancing their longevity and performance in different environments. Despite their impressive qualities, color coated steel coils remain cost-effective, providing a cost-efficient solution for various industries seeking a durable and visually appealing material for their projects.
Silicon modified polyester(SMP): One possible material that fits these criteria is polyurethane. Polyurethane coatings are known for their excellent abrasion and heat resistance, making them suitable for a wide range of applications. They also have good external durability and chalking resistance, as well as good gloss retention and flexibility. Additionally, polyurethane coatings are relatively cost-effective compared to other high-performance coatings.
High Durability Polyester(HDP): In addition to these qualities, the paint also boasts exceptional resistance to harsh weather conditions, making it ideal for long-term outdoor use. Its anti-ultraviolet properties ensure that the vibrant colors will remain intact even under direct sunlight exposure. Furthermore, the paint's anti-pulverization feature guarantees a smooth and pristine finish that will last for years to come. With its strong adhesion to various surfaces, the paint creates a durable and long-lasting film that enhances the overall appearance of any project. The wide range of rich colors available provides endless possibilities for creative expression, all while maintaining excellent cost performance.
Polyvinylidene Fluoride(PVDF): These characteristics describe a high-quality, durable coating or paint that is specifically designed for outdoor applications. The excellent color retention and UV resistance indicate that the coating will not fade or deteriorate when exposed to sunlight, while the solvent resistance ensures that it will not be easily damaged by chemicals or other harsh substances. The good moldability means that the coating can be easily shaped or molded to fit different surfaces, and the stain resistance indicates that it will be easy to clean and maintain. However, the limited color options and high cost suggest that this coating may be more expensive and less customizable than other options. Overall, this coating would be a great choice for outdoor applications where durability and longevity are important.
Polyurethane (PU): Polyurethane coating is known for its exceptional durability and resistance to wear, corrosion, and damage. It is a popular choice for buildings and structures that are exposed to harsh environmental conditions, such as extreme temperatures, moisture, and chemical exposure. The coating can withstand these conditions for an extended period, with a typical shelf life of more than 20 years. This makes it a cost-effective and long-lasting solution for protecting surfaces from corrosion and deterioration. Overall, polyurethane coating is a reliable option for applications where high performance and longevity are essential.
