Paint System Comparison: PE, SMP, HDP & PVDF
The paint system determines the service life, color retention and price of a PPGI coil. Buyers should choose the coating based on climate and application:
| Paint System | Top / Back Film | Weatherability | Typical Warranty | Best For |
|---|---|---|---|---|
| PE (Polyester) | 18-25 / 5-7 µm | Good | 5-10 years | Interior, general roofing, budget projects |
| SMP (Silicon Modified Polyester) | 20-25 / 7 µm | Very good | 10-15 years | Exterior cladding, higher surface hardness |
| HDP (High-Durability Polyester) | 20-25 / 7 µm | Excellent | 15-20 years | Long-life roofing, strong color stability |
| PVDF (Fluorocarbon, 70% Kynar/Hylar) | 25 / 15 µm | Superior | 20+ years | Coastal, high-UV and architectural facades |
Popular RAL colors in stock include RAL 9002, RAL 9006, RAL 5015, RAL 3005 and RAL 6005. Custom RAL shades and zinc coatings from Z40 to Z275 are available to order, with PVDF 25/15 µm systems recommended for coastal and high-radiation climates.

FAQ
What is the difference between PPGI and GI coil?
GI Coil (Galvanized Iron Coil) has a zinc coating for basic corrosion resistance. PPGI Coil (Prepainted Galvanized Iron Coil) takes this further by adding multiple layers of paint (primer and topcoat) on top of the galvanized layer. This prepainted galvanized steel coil provides enhanced protection against weathering, UV rays, and chemicals, along with a wide range of aesthetic color options, making it superior for applications where both durability and appearance are important.
What are the main paint systems used for color coated coil?
The most common paint systems for color coated coil are Polyester (PE), Silicon Modified Polyester (SMP), and Polyvinylidene Fluoride (PVDF). PE offers good durability and cost-effectiveness for general use. SMP provides better weather resistance and color retention. PVDF (also known as Hylar) offers the highest performance with exceptional resistance to UV fading, chalking, and chemicals, making it ideal for harsh environments and architectural applications.
What is the typical lead time for ordering prepainted steel from China?
The standard production and shipping lead time for ordering prepainted galvanized steel coil from our Qingdao factory is 15 to 25 days after order confirmation and receipt of payment. This timeframe covers manufacturing, quality inspection, and preparation for shipment. For very large or custom orders, our team will provide a precise timeline. We are known as a reliable PPGI supplier for maintaining consistent lead times to keep your projects on schedule.
Can you supply small quantities or samples of PPGI coil?
While our standard Minimum Order Quantity (MOQ) is 25 tons for production orders, we can often provide sample coils or smaller test quantities for color matching and quality verification before you place a full order. As a customer-focused PPGI supplier, we encourage you to contact us to discuss your specific needs for samples or trial orders of color coated coil.

PPGI Coil Buying Checklist
A comparable PPGI quotation needs more than thickness and colour. Ask every supplier to quote the same substrate grade, metallic coating, paint system, tolerances, coil weight and packing method.
1. Base metal and coating
State the required grade, zinc or aluzinc coating mass, nominal thickness and acceptable tolerance. A lower coating mass can reduce the initial price but changes corrosion performance.
2. Paint specification
Confirm the RAL colour, top and back paint thickness, gloss, primer and whether PE, SMP, HDP or PVDF is required for the exposure conditions.
3. Coil and packing
Specify width, coil ID, target coil weight, edge condition, protective film, eye-to-sky or eye-to-wall loading, and destination-port requirements.
Documents to request before shipment
- Mill test certificate showing grade and mechanical properties
- Coating and paint-thickness inspection report
- RAL colour sample or signed colour confirmation
- Coil packing list with net and gross weight
- Loading photos and container-securing record
