What Is Anti Finger Print AFP Galvalume Coil?

Anti finger print (AFP) galvalume coil is a premium steel product coated with a thin, transparent polymer layer that prevents fingerprints, smudges, and stains from adhering to the surface. The base metal is galvalume steel (also known as aluzinc), which consists of approximately 55% aluminum, 43.4% zinc, and 1.6% silicon by weight. This combination offers superior corrosion resistance compared to traditional galvanized steel. The AFP treatment is applied after the hot-dip coating process, creating a smooth, matte or glossy finish that is easy to clean and maintain. Common grades include DX51D, AZ150, and AZ100, all conforming to ASTM A792M. This product is widely used for metal roofing coil, HVAC panels, electronic enclosures, and household appliances.

Key Benefits of AFP Galvalume Coil

Fingerprint resistance – The AFP coating repels oils and dirt, keeping surfaces clean during handling and installation.
Enhanced corrosion protection – The aluzinc layer provides up to 4 times the lifespan of standard galvanized steel in many environments.
Excellent formability – Suitable for roll forming, bending, and stamping without cracking the coating.
UV and weather resistance – Ideal for outdoor roofing and wall cladding applications.
Cost-effective – Lower maintenance and longer service life reduce total ownership costs.

Applications of Anti Finger Print AFP Galvalume Coil

The unique properties of AFP galvalume coil make it suitable for a wide range of industries. Here are the most common uses:

Roofing and cladding – Metal roofing coil with AFP coating resists dirt buildup and maintains a clean appearance for decades.
Home appliances – Refrigerators, washing machines, and microwave ovens benefit from fingerprint-resistant surfaces that are easy to clean.
Electronics enclosures – Computer cases, server racks, and control panels require a non-stick surface to prevent smudges during assembly.
Automotive parts – Interior trim and underbody components use AFP galvalume for its corrosion resistance and aesthetic finish.
HVAC systems – Ductwork and air handler housings stay cleaner longer with AFP coating.

In addition, the AZ150 galvalume grade is particularly popular for coastal and industrial environments where salt spray and chemical exposure are concerns. The combination of aluzinc and AFP coating provides a robust barrier against rust and staining.

Quality Certifications and Standards

All our products meet or exceed ASTM A792M, EN 10147, and JIS G3321 standards. We also offer chromium-free AFP coatings that comply with RoHS and REACH regulations, making them safe for use in food-contact appliances and sensitive electronic applications. Our quality control team performs salt spray tests (ASTM B117) to verify corrosion resistance, and we provide mill test certificates with every shipment.

Frequently Asked Questions

1. What is the difference between AFP galvalume and standard galvalume coil?
AFP galvalume has an additional transparent polymer coating that repels fingerprints, oils, and dirt. Standard galvalume lacks this top layer, making it more prone to smudging during handling. AFP is ideal for visible surfaces in appliances and architectural panels.

2. Can AFP galvalume coil be painted or powder coated?
Yes, but the AFP coating must be removed or chemically treated before painting. For most applications, the AFP finish is designed to be the final surface. If you require a painted finish, we recommend ordering our pre-painted galvalume coil instead.

3. What is the minimum order quantity (MOQ) for AFP galvalume coil?
Our MOQ is 25 metric tons per specification. For smaller trial orders, we may accommodate partial loads subject to availability. Contact our sales team to discuss your specific needs.

4. How do I choose between AZ100 and AZ150 coating?
AZ150 offers double the coating weight of AZ100, providing significantly better corrosion resistance. For roofing and exterior applications, AZ150 is recommended. For indoor use with minimal exposure, AZ100 is cost-effective and sufficient.

5. What is the typical lead time for an order?
For standard sizes (0.4–1.2mm thickness, 1000–1250mm width), lead time is 15–20 working days from our factory in Boxing, Binzhou. Custom specifications may require 25–30 days. We offer express production for urgent orders at a small premium.
