PVDF Coated Metal Coil

PVDF-coated metal coil is a high-performance pre-painted material featuring a polyvinylidene fluoride (PVDF) fluorocarbon resin coating cured onto the metal substrate surface via a high-temperature baking process. This coating system is recognized as the premier choice in architectural coatings, renowned for its exceptional durability and protective properties. It is widely used in applications demanding stringent requirements for material longevity and appearance retention

Our PVDF Coating Technology

Thoroughly clean the metal substrate prior to coating; the substrate must be clean and free of contamination, with the chemical pretreatment film intact and undamaged;
Maintain a highly clean coating environment, strictly controlling the cleanliness of the coating chamber to prevent impurities from affecting coating flatness;
Ensure stable coating viscosity throughout the process to guarantee uniform coating thickness;
Primers are selected from polyurethane or epoxy types to guarantee coating adhesion to the substrate;
Filtration systems undergo regular inspection during coating, with clogged or damaged filters replaced promptly to prevent impurity contamination;
During baking, precisely control panel temperature (PMT) to 249°C with a curing time set to 23 seconds;
After baking, select either air cooling or water cooling based on production requirements to ensure stable coating formation.

Features of PVDF Coated Metal Coil

Exceptional Stability: The fluorocarbon bond structure provides the coating with outstanding chemical stability, maintaining consistent performance over extended periods in acidic, alkaline, and polluted environments.
Exceptional Durability: Withstands over 20 years of outdoor exposure while maintaining color integrity and gloss, featuring outstanding UV resistance.
Superior Processability: Flexible and impact-resistant coating supports post-forming operations including embossing, bending, and cutting.
Lightweight, High-Strength, and Eco-Friendly: Combines lightweight construction, high strength, and corrosion resistance without releasing harmful substances, aligning with green building standards.
Fire-Resistant, Moisture-Proof & Composite Applications: Commonly used in systems like polyurethane-edged composite panels as surface or edging materials, enhancing overall fire resistance, thermal insulation, and structural strength.
Easy & Efficient Installation: Lightweight material with excellent workability simplifies installation processes, shortening construction timelines while delivering both practicality and aesthetics.

PVDF Coated Metal Coil Application

With outstanding corrosion resistance, UV resistance, lightweight aesthetics, and easy processing, PVDF-coated metal coil finds extensive applications:

Buildings exposed to harsh environments long-term, such as stadiums, high-speed rail stations, power plants, coastal areas, and high-altitude regions;
Exterior wall and roofing systems for public buildings and industrial facilities requiring high aesthetics and durability;
Providing a new eco-friendly raw material that is weather-resistant, lightweight, and ready for direct processing for industries including shipbuilding, vehicle manufacturing, furniture, and electrical equipment.

Wanzhi PVDF Coated Steel Products

PVDF coated on galvanized steel coil(PPGI Coil)

It has dual anti-rust functions of galvanized layer and pvdf coating, and has excellent processability and high cost performance.

PVDF coated on galvalume steel coil (PPGL Coil)

It has stronger corrosion resistance, very long service life, and is resistant to high temperature and humidity.

PVDF coated on aluminum coil (PPAL Coil)

It is very light, very corrosion-resistant, and has good ductility.

Comparison and recommendations of three products

Item	PVDF galvanized steel coil	PVDF Galvalume Steel Coil	PVDF Aluminum Coil
Corrosion Resistance	Medium (depends on the galvanized layer)	Excellent (self-healing of galvalume)	Excellent (aluminum base + coating)
Weight	Heavy (steel substrate)	Heavy (steel substrate)	Light (aluminum base)
Cost	Relatively low	High	High
Typical Applications	Chemical equipment, ordinary curtain wall	Extreme environment, high-end curtain wall	Extreme environment, super high-rise, artistic decoration

Note: For coastal projects with limited budget, PVDF-coated galvanized steel + Z275 galvanized layer is also suitable for coastal high-corrosion environments.
